Json 代码不起作用

Question

NSString *urlString = @"http://chkdin.com/dev/api/peoplearoundmexy/?";
NSURL *url = [NSURL URLWithString:urlString];

NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];

NSString *parameterString=[NSString stringWithFormat:@"skey=%@&user_id=%@",@"XXXXXXX",@"3225"];


NSLog(@"%@",parameterString);


[request setHTTPMethod:@"POST"];

[request setURL:url];

[request setValue:parameterString forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];


NSData *postData = [parameterString dataUsingEncoding:NSUTF8StringEncoding];

[request setHTTPBody:postData];

    NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&error];
    NSLog(@"%@",[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error]);
    NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
    NSLog(@"%@",dict);

这是我的 json 解析，我的问题是当我点击这个 api 时它正在显示

{
  message = "Valid skey required.";
status = 0;
}

但是这个 api 在 safari 中工作。我认为问题是请求添加到 url 错误。你能帮我吗....

Answer 1

我尝试在没有AFNetworking 的情况下使用以下代码并且它工作正常。

NSString *post = [NSString stringWithFormat:@"skey=%@&user_id=%@",@"sa6rw9er7twefc9a7dvcxcheckedin",@"3225"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:[NSString stringWithFormat:@"http://chkdin.com/dev/api/peoplearoundmexy/?%@",post]]];
[request setHTTPMethod:@"POST"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:nil];
NSError *error;

NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:&error];
NSLog(@"%@",[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error]);
NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSLog(@"%@",dict);

我通过 AFNetworking 3 得到响应

试试这个

 AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    [manager GET:@"http://chkdin.com/dev/api/peoplearoundmexy/?" parameters:@{@"skey":@"sa6rw9er7twefc9a7dvcxcheckedin",@"user_id":@"3225"} progress:nil success:^(NSURLSessionTask *task, id responseObject) {
        NSLog(@"%@",responseObject);
    } failure:^(NSURLSessionTask *operation, NSError *error) {
    }];
