Objective c 当使用obj c将数据发布到parse.com时，我得到的响应为code=107 error="；无效的json:"；

当我试图通过NsMutableUrlRequest将url发布到Parse.com时，得到的响应如下 代码=107； error=“无效json:”

该函数是用javaScript编写的

但是当我从curl发帖时，我得到了确切的输出

curl -X POST \

  -H "X-Parse-Application-Id: appID" \

  -H "X-Parse-REST-API-Key: restAPiKEy" \

  -H "Content-Type: application/json" \

  -d '{}' \

但在目标c中，我得到了错误 这是我的密码

 NSURL *URL = [NSURL URLWithString:@"https://api.parse.com/1/functions/hello"];
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL];
    request.HTTPMethod = @"POST";


    NSString * params = @"----the app id---=X-Parse-Application-Id&-----the rest api key=X-Parse-REST-API-Key";


    NSData *data = [params dataUsingEncoding:NSUTF8StringEncoding];

    [request setValue:@"APPID" forHTTPHeaderField:@"X-Parse-Application-Id"];
    [request setValue:@"REST API KEY" forHTTPHeaderField:@"X-Parse-REST-API-Key"];
    [request addValue:@"8bit" forHTTPHeaderField:@"Content-Transfer-Encoding"];
    [request addValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request addValue:[NSString stringWithFormat:@"%lu", (unsigned long)[data length]] forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody:data];

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
        // Peform the request
        NSURLResponse *response;
        NSError *error = nil;
        NSData *receivedData = [NSURLConnection sendSynchronousRequest:request
                                                     returningResponse:&response
                                                                 error:&error];
        NSDictionary *dictOfNews  = [NSJSONSerialization
                                     JSONObjectWithData:receivedData //1
                                     options:kNilOptions
                                     error:&error];

        NSLog(@"dict of the news: %@", dictOfNews);


        if (error) {
            // Deal with your error
            if ([response isKindOfClass:[NSHTTPURLResponse class]]) {
                NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse*)response;
                NSLog(@"HTTP Error: %ld %@", (long)httpResponse.statusCode, error);
                return;
            }
            NSLog(@"Error %@", error);

        }
        else
        {
            NSLog(@"SUCCESS GRAND SUCCESS");
        }

    });

请告诉我，我哪里做错了。提前感谢

我只是好奇你为什么要这么做，有一个原生的Objective-C API为你包装了其余的调用@TimothyWalters我正在使用你提到的url保存和获取对象，但这是用javascript编写的云代码（），要获取数据，有没有其他方法在Xcode中获取“”[PFCloud callFunctionInBackground:@“hello”with Parameters@{}block:…]@TimothyWalters非常感谢。这非常有效而且非常简单。。
