Question

我想使用afnetworking 2.0将数据发送到网址。我将字典值作为参数传递。以下是我的代码。

NSError *错误; NSData * executionsData = [NSJSONSerialization dataWithJSONObject：dic options：NSJSONWritingPrettyPrinted error：＆amp; error];

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"my url"]];
[request setTimeoutInterval:600];
[request setHTTPMethod:@"POST"];
[request setValue:[NSString stringWithFormat:@"%lu", (unsigned long)executionsData.length] forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:executionsData];
[request setValue:[self userAgent] forHTTPHeaderField:@"User-Agent"];


AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];
op.responseSerializer = [AFJSONResponseSerializer serializer];

[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSDictionary* resultsDict   = (NSDictionary*)responseObject;
    NSLog(@"%@", resultsDict);
    //process result json dictionary

    //success
    //success();
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    //failure
    NSLog(@"Error:%@",error);
    //failure();
}];

但每次执行此代码时，我都会收到如下错误。

我是IOS的新手，对afnetworking不太了解。有人会为此重播吗？

使用AFHTTPSessionManager及其方法POST:parameters:success:failure:。您可以在此处找到更多示例：挂钩到Live Service 标题下的http://www.raywenderlich.com/59255/afnetworking-2-0-tutorial。
