首先给出使用例子
AFURLSessionManager 使用方法:

AFURLSessionManager
1.请求服务器数据
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration]; AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration]; NSURL *URL = [NSURL URLWithString:@“http://example.com/download.zip"]; NSURLRequest *request = [NSURLRequest requestWithURL:URL]; NSURLSessionDownloadTask *downloadTask = [manager downloadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) { NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil]; return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]]; } completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) { NSLog(@"File downloaded to: %@", filePath); }]; [downloadTask resume];
2.上传数据
NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration]; AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:configuration]; NSURL *URL = [NSURL URLWithString:@"http://example.com/download.zip"]; NSURLRequest *request = [NSURLRequest requestWithURL:URL]; NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithRequest:request progress:nil destination:^NSURL *(NSURL *targetPath, NSURLResponse *response) { NSURL *documentsDirectoryURL = [[NSFileManager defaultManager] URLForDirectory:NSDocumentDirectory inDomain:NSUserDomainMask appropriateForURL:nil create:NO error:nil]; return [documentsDirectoryURL URLByAppendingPathComponent:[response suggestedFilename]]; } completionHandler:^(NSURLResponse *response, NSURL *filePath, NSError *error) { NSLog(@"File downloaded to: %@", filePath); }]; [downloadTask resume];
3.多线程下载数据
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://example.com/upload" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { [formData appendPartWithFileURL:[NSURL fileURLWithPath:@"file://path/to/image.jpg"] name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" error:nil]; } error:nil]; AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; NSURLSessionUploadTask *uploadTask; uploadTask = [manager uploadTaskWithStreamedRequest:request progress:^(NSProgress * _Nonnull uploadProgress) { // This is not called back on the main queue. // You are responsible for dispatching to the main queue for UI updates dispatch_async(dispatch_get_main_queue(), ^{ //Update the progress view [progressView setProgress:uploadProgress.fractionCompleted]; }); } completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) { if (error) { NSLog(@"Error: %@", error); } else { NSLog(@"%@ %@", response, responseObject); } }]; [uploadTask resume];

1.post请求
- (nullable NSURLSessionDataTask *)POST:(NSString *)URLString parameters:(nullable id)parameters success:(nullable void (^)(NSURLSessionDataTask *task, id _Nullable responseObject))success failure:(nullable void (^)(NSURLSessionDataTask * _Nullable task, NSError *error))failure DEPRECATED_ATTRIBUTE;
2.get请求
- (nullable NSURLSessionDataTask *)GET:(NSString *)URLString parameters:(nullable id)parameters success:(nullable void (^)(NSURLSessionDataTask *task, id _Nullable responseObject))success failure:(nullable void (^)(NSURLSessionDataTask * _Nullable task, NSError *error))failure
