AFNetworking3.0和之前的

3.0后的初始化方法

AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

GET方法

[manager GET:URLString parameters:parameter progress:^(NSProgress * _Nonnull downloadProgress) {

if (progress) {progress(downloadProgress);

}

} success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

if (success) {

success(responseObject);

}

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

if (failure) {

failure(error);

}

}];

POST方法

[manager POST:URLString parameters:parameter progress:^(NSProgress * _Nonnull uploadProgress) {

if (progress) {

progress(uploadProgress);

}

} success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

if (success) {

success(responseObject);

}

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

if (failure) {

failure(error);

}

}];

之前的版本初始化

AFHTTPRequestOperationManager * manager =[AFHTTPRequestOperationManager manager];

GET方法

[manager GET:urlString parameters:nil success:^(AFHTTPRequestOperation * _Nonnull operation, id  _Nonnull responseObject) {

// NSLog(@"%@",responseObject);

if (complete) {

complete(responseObject);//调用block将请求数据返回

}

} failure:^(AFHTTPRequestOperation * _Nullable operation, NSError * _Nonnull error) {

if (failure) {

failure(error);//将错误信息返回

}

}];

POST方法

//请求

[requestManager POST:urlString parameters:paras success:^(AFHTTPRequestOperation *operation, id responseObject){

NSLog(@"%@",responseObject);

if (complete) {

complete(responseObject);

}

} failure:^(AFHTTPRequestOperation * __nullable operation, NSError *error){

if (failure) {

failure(error);

}

}];

成功或失败的回调Block

typedef void (^CompleteCallBack)(id data);//请求完成时的回调

typedef void (^FailureCallBack)(NSError* error);//请求出错的回调

返回格式的设置

manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html", nil];

返回二进制流

//设置返回数据格式（二进制）

manager.responseSerializer = [AFHTTPResponseSerializer serializer];
