iOS:POST，其中JSON只是众多参数中的一个

通过将JSON的数据表示形式设置为HTTP正文，我已成功地将JSON用作我的应用程序中发布webservices的参数：

    //Prep
    NSData *requestData = [NSJSONSerialization dataWithJSONObject:<my JSON> options:0 error:nil];
    NSString *apiString = <the webservice>;

    //POST
    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:apiString]];
    [request setHTTPMethod:@"POST"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody:requestData];

    //Go
    NSURLResponse *response = nil;
    queryResultData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];

必须作为帖子提交

有趣的是，JSON字典只是许多参数中的一个参数，而不是在主体中。我不知道如何在帖子中添加这些参数

编辑 在php中也有相同的概念。用可可粉怎么做

$data = array('x' => 1, 'name => 'fred');

$json = json_encode($data);

curl_setopt($curl_handle, CURLOPT_POSTFIELDS, array('json_data' => $json));
 -- or --
curl_setopt($curl_handle, CURLOPT_POSTFIELDS, 'something=whatever&json_data='.$json);

$data = array('x' => 1, 'name => 'fred');

$json = json_encode($data);

curl_setopt($curl_handle, CURLOPT_POSTFIELDS, array('json_data' => $json));
 -- or --
curl_setopt($curl_handle, CURLOPT_POSTFIELDS, 'something=whatever&json_data='.$json);
