JSON正文AFNetworking 2.0的POST请求 [英] POST request with JSON body AFNetworking 2.0

问题描述

反正有使用AFNetworking〜> 2.0发送带有JSON正文的POST请求吗？

Is there anyway to send a POST request with a JSON body using AFNetworking ~> 2.0?

我尝试使用：

manager.requestSerializer = [AFJSONRequestSerializer序列化器];
经理POST：< url>参数：@ {@数据：@值}成功：< block>失败：< block>’


，但是它不起作用。任何帮助是极大的赞赏。
谢谢

but it doesn't work. Any help is greatly appreciated. Thanks

推荐答案

您可以在 NSMutableURLRequest 在参数中不直接输入：。参见我的示例代码：

You can add your JSON body in NSMutableURLRequest not direct in parameters:. See my sample code :

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
// Set post method
[request setHTTPMethod:@"POST"];
// Set header to accept JSON request
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
// Your params
NSDictionary *params = @{@"data":@"value"};
// Change your 'params' dictionary to JSON string to set it into HTTP
// body. Dictionary type will be not understanding by request.
NSString *jsonString = [self getJSONStringWithDictionary:params];

// And finally, add it to HTTP body and job done.
[request setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]];

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
manager.requestSerializer = [AFJSONRequestSerializer serializer];
AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request success:<block> failure:<block>];
