Introduction

SJNetwork provides a high level network request API based on AFNetworking and inspired by YTKNetwork: generating network request object according to the configuration of a specific network request(url, method, parameters etc.) and managing requests by the corresponding objects.

Document for Chinese-convenient reader:中文文档

Features

  • Ordinary request: sending GET,POST,PUT,DELETE network request.
    • write and load caches, configure cache available time duration​
  • Upload request: sending upload image(s) network request
    • one and more than one image uploading and configure compress ratio before uploading​
  • Download request: sending download file network request
    • resumable or not
    • background downloading supporting or not
  • Default parameters:default parameters will be added on request body
  • Custom header: configuring custom request header(key-value)
  • Base url configuration : server url of network requests
  • Request management:canceling one or more than one current network requests; checking current requests’ information
  • Cache operation: writing, loading or clearing one or more than one cache of network requests ; calculating cache size
  • Debug mode switch: for convenience of debugging

Usage

Method1: using Cocoapods:

pod 'SJNetwork'

then

#import <SJNetwork/SJNetwork.h>

Method2: moving SJNetworkfolder into your project.

then

#import "SJNetwork.h"

Basic Configuration

Server url

[SJNetworkConfig sharedConfig].baseUrl = @"http://v.juhe.cn";

Default parameters

[SJNetworkConfig sharedConfig].defailtParameters = @{@"app_version":[[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleShortVersionString"],
                                                        @"platform":@"iOS"};

Timeout seconds

[SJNetworkConfig sharedConfig].timeoutSeconds = 30;//default is 20s

Debug mode

[SJNetworkConfig sharedConfig].debugMode = YES;//default is NO

Add request header

[[SJNetworkConfig sharedConfig] addCustomHeader:@{@"token":@"2j4jd9s74bfm9sn3"}];

or

[[SJNetworkManager sharedManager] addCustomHeader:@{@"token":@"2j4jd9s74bfm9sn3"}];

The input key-value pair will be added in network request header.

If a pair with same key-value dose not exist, then add it, if it exists, then replace it.

Ordinary Network Request

POST request (none writing or none loading cache):

[[SJNetworkManager sharedManager] sendPostRequest:@"toutiao/index"
                                       parameters:@{@"type":@"top",
                                                    @"key" :@"0c60"}

     success:^(id responseObject) {

  } failure:^(NSURLSessionTask *task, NSError *error, NSInteger statusCode) {

  }];

POST request ( writing and loading cache):

[[SJNetworkManager sharedManager] sendPostRequest:@"toutiao/index"
                                       parameters:@{@"type":@"top",
                                                    @"key" :@"0c60"}
                                        loadCache:YES
                                    cacheDuration:180
  success:^(id responseObject) {

} failure:^(NSURLSessionTask *task, NSError *error, NSInteger statusCode) {

}];

If loadcache is set to be YES, then try to load cache before sending network request.

If cacheDuration is set to be more than 0, then write cache after receiving response object.

Flow chart of cache operation in ordinary requests:

Cache Operation

Loading cache

Loading cache of a specific network request:

[[SJNetworkManager sharedManager] loadCacheWithUrl:@"toutiao/index"
                                            method:@"POST"
                                        parameters:@{@"type":@"top",
                                                     @"key" :@"0c60"}
                                 completionBlock:^(id  _Nullable cacheObject) {                               
}];

Loading cache of network requests share the same request url:

[[SJNetworkManager sharedManager] loadCacheWithUrl:@"toutiao/index"
                                   completionBlock:^(NSArray * _Nullable cacheArr) {
}];

Loading cache of network requests which share the same request url and method:

[[SJNetworkManager sharedManager] loadCacheWithUrl:@"toutiao/index"
                                            method:@"POST"
                                   completionBlock:^(NSArray * _Nullable cacheArr) {
}];

Clearing Cache

Clearing cache of one specific network request:

[[SJNetworkManager sharedManager] clearCacheWithUrl:@"toutiao/index"
                                             method:@"POST"
                                         parameters:@{@"type":@"top",
                                                      @"key" :@"0c60"}
                                    completionBlock:^(BOOL isSuccess) {
}];

Clearing cache of network requests share the same request url:

[[SJNetworkManager sharedManager] clearCacheWithUrl:@"toutiao/index"
                                    completionBlock:^(BOOL isSuccess) {
}];

Clearing cache of network requests which share the same request url and method:

[[SJNetworkManager sharedManager] clearCacheWithUrl:@"toutiao/index"
                                             method:@"POST"
                                    completionBlock:^(BOOL isSuccess) {
}];

Calculating Cache

Calculating the size of cache folder:

[[SJNetworkManager sharedManager] calculateCacheSizeWithCompletionBlock:^(NSUInteger fileCount, NSUInteger totalSize, NSString *totalSizeString) {

        NSLog(@"file count :%lu and total size:%lu total size string:%@",(unsigned long)fileCount,(unsigned long)totalSize, totalSizeString);

}];

fileCount:file counts in cache folder

totalSize: size of cache folder(unit is byte)

totalSizeString:size of cache folder (size of unit) eg.file count :5 and total size:1298609 total size string:1.2385 MB

Uploading Function

Uploading one image, original size:

[[SJNetworkManager sharedManager]  sendUploadImageRequest:@"api"
                                               parameters:nil
                                                    image:image_1
                                                     name:@"universe"
                                                 mimeType:@"png"
                                                 progress:^(NSProgress *uploadProgress) {

  self.progressView.observedProgress = uploadProgress;

} success:^(id responseObject) {

} failure:^(NSURLSessionTask *task, NSError *error, NSInteger statusCode, NSArray<UIImage *> *uploadFailedImages) {

}];

Here, the mimeType can be jpg/JPG, png/PNG, jpeg/JPEG and if the user gives a wrong type, the mimeType will be jpg.

Uploading two images, compress ratio is 0.5(note that if the mineType is ‘png’ or ‘PNG’, the compressRatio will be useless):

[[SJNetworkManager sharedManager]  sendUploadImagesRequest:@"api"
                                                parameters:nil
                                                    images:@[image_1,image_2]
                                             compressRatio:0.5
                                                      name:@"images"
                                                  mimeType:@"jpg"
                                                  progress:^(NSProgress *uploadProgress) {

  self.progressView.observedProgress = uploadProgress;

} success:^(id responseObject) {

} failure:^(NSURLSessionTask *task, NSError *error, NSInteger statusCode, NSArray<UIImage *> *uploadFailedImages) {

}];

And if the server which is used for uploading is different from the server for ordinary requests, you can user this api:

[[SJNetworkManager sharedManager]  sendUploadImagesRequest:@"http://uploads.im/api"
                                               ignoreBaseUrl:YES
                                                  parameters:nil
                                                      images:@[image_1,image_2]
                                               compressRatio:0.5
                                                        name:@"images"
                                                    mimeType:@"jpg"
                                                    progress:^(NSProgress *uploadProgress) {

      self.progressView.observedProgress = uploadProgress;

  } success:^(id responseObject) {

  } failure:^(NSURLSessionTask *task, NSError *error, NSInteger statusCode, NSArray<UIImage *> *uploadFailedImages) {

  }];

Here, setting ignoreBaseUrl to be YES, and the request url should be complete download url.

Downloading Function:

We support background downloading(using NSURLSessionDownloadTask object ) and none-background downloading(using NSURLSessionDataTask object) , resumable or none-resumable downloading.

resumable none-resumable
background supporting
none-background supporting

Note:If a none-background supporting downloading is on going then app enters into background, the downloading task will be canceled. And When app enters into foreground again, an auto-resume mechanism will make the downloading task restart again.

Sending download request

Resumable && none-background supporting download reqeust (default configuration):

[[SJNetworkManager sharedManager] sendDownloadRequest:@"wallpaper.jpg"
                                     downloadFilePath:_imageFileLocalPath
                                             progress:^(NSInteger receivedSize, NSInteger expectedSize, CGFloat progress)
{
       self.progressView.progress = progress;

} success:^(id responseObject) {

} failure:^(NSURLSessionTask *task, NSError *error, NSString *resumableDataPath) {

}];

None-resumable && none-background supporting download reqeust:

[[SJNetworkManager sharedManager] sendDownloadRequest:@"half-eatch.jpg"
                                     downloadFilePath:_imageFileLocalPath
                                            resumable:NO
                                    backgroundSupport:NO
                                             progress:^(NSInteger receivedSize, NSInteger expectedSize, CGFloat progress) 
{

    self.progressView.progress = progress;

} success:^(id responseObject) {

} failure:^(NSURLSessionTask *task, NSError *error, NSString *resumableDataPath) {

}];

Resumable && background supporting download request:

[[SJNetworkManager sharedManager] sendDownloadRequest:@"universe.jpg"
                                     downloadFilePath:_imageFileLocalPath
                                            resumable:YES
                                    backgroundSupport:YES
                                             progress:^(NSInteger receivedSize, NSInteger expectedSize, CGFloat progress)
{

    self.progressView.progress = progress;

} success:^(id responseObject) {

} failure:^(NSURLSessionTask *task, NSError *error, NSString *resumableDataPath) {

}];

None-resumable && background supporting download request:

[[SJNetworkManager sharedManager] sendDownloadRequest:@"iceberg.jpg"
                                     downloadFilePath:_imageFileLocalPath
                                            resumable:NO
                                    backgroundSupport:YES
                                             progress:^(NSInteger receivedSize, NSInteger expectedSize, CGFloat progress)
{

    self.progressView.progress = progress;

 } success:^(id responseObject) {

 } failure:^(NSURLSessionTask *task, NSError *error, NSString *resumableDataPath) {

 }];

Also supports ignoring base url:

[[SJNetworkManager sharedManager] sendDownloadRequest:@"http://oih3a9o4n.bkt.clouddn.com/wallpaper.jpg"
                                        ignoreBaseUrl:YES
                                     downloadFilePath:_imageFileLocalPath
                                             progress:^(NSInteger receivedSize, NSInteger expectedSize, CGFloat progress)
{
      self.progressView.progress = progress;

} success:^(id responseObject) {

} failure:^(NSURLSessionTask *task, NSError *error, NSString *resumableDataPath) {

}];

Suspending download request

Suspending one download current request:

[[SJNetworkManager sharedManager] suspendDownloadRequest:@"universe.jpg"];

Suspending one or more than one current download requests:

[[SJNetworkManager sharedManager] suspendDownloadRequests:@[@"universe.jpg",@"wallpaper.jpg"]];

Suspending all current download requests:

[[SJNetworkManager sharedManager] suspendAllDownloadRequests];

Resuming download request

Request Management

Current request(s) Information

Checking if there is remaining current request(s):

BOOL remaining =  [[SJNetworkManager sharedManager] remainingCurrentRequests];
if (remaining) {
    NSLog(@"There is remaining request");
}

Calculating count of current request(s):

NSUInteger count = [[SJNetworkManager sharedManager] currentRequestCount];
if (count > 0) {
    NSLog(@"There is %lu requests",(unsigned long)count);
}

Logging all current request(s):

[[SJNetworkManager sharedManager] logAllCurrentRequests];

Canceling request

Canceling one network request:

[[SJNetworkManager sharedManager] cancelCurrentRequestWithUrl:@"toutiao/index"
                                                       method:@"POST"
                                                   parameters:@{@"type":@"top",
                                                                @"key" :@"0c60"}];

Canceling network request(s) with the same url:

[[SJNetworkManager sharedManager] cancelCurrentRequestWithUrl:@"toutiao/index"];

Canceling network request(s) with the same urls:

[[SJNetworkManager sharedManager] cancelDownloadRequests:@[@"toutiao/index",@"weixin/query"]];

Canceling all current network request(s):

[[SJNetworkManager sharedManager] cancelAllCurrentRequests];

Log Output

If debug mode is set to be yes, detail log will be provided:

[SJNetworkConfig sharedConfig].debugMode = YES;

Loading cache before sending network request, but cache is expired:

=========== Load cache info failed, reason:Cache is expired, begin to clear cache...
=========== Load cache failed: Cache info is invalid 
=========== Failed to load cache, start to sending network request...
=========== Start requesting...
=========== url:http://v.juhe.cn/toutiao/index
=========== method:GET
=========== parameters:{
    app_version = 1.0;
    key = 0c60;
    platform = iOS;
    type = top;
}
=========== Request succeed! 
=========== Request url:http://v.juhe.cn/toutiao/index
=========== Response object:{
  code = 200,
  msg = "",
  data = {}
}
=========== Write cache succeed!
=========== cache object: {
  code = 200,
  msg = "",
  data = {}
