通过键值对读取jSON对象请求
我正在尝试阅读jSON对的forms的jSON响应。
当我通过浏览器手动点击URL时，通过jSON对象获得所需的状态码/响应
{"status":"0","responseCode":"1021","response":{"message":"Please check your Settings ","data":"2012-11-24, 7:28 am"}}
当我试图通过我的app.My代码，当我通过应用程序发送数据时得到相同的预期响应
[dictionnary setObject:@"admin" forKey:@"username"]; [dictionnary setObject:@"123123" forKey:@"password"]; NSError *error = nil; NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionnary options:kNilOptions error:&error]; NSString *urlString = @"MY CALL URL"; NSURL *url = [NSURL URLWithString:urlString]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod:@"POST"]; [request setHTTPBody:jsonData]; NSURLResponse *response = NULL; NSError *requestError = NULL; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&requestError]; NSLog(@"response is obtained"); NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding] ; NSLog(@"%@", responseString);
响应我正在通过代码获取

在你的URLRequest中指定你不想要html，但你想要原始的json
NSURL *url = [NSURL URLWithString:urlString]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod:@"POST"];
至：
NSURL *url = [NSURL URLWithString:urlString]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod:@"POST"]; [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];//!!!
你可以尝试下面的代码可能会帮助你。
NSString *username = emailField.text; NSString *password = passwordField.text; NSMutableDictionary *dictionnary = [NSMutableDictionary dictionary]; [dictionnary setObject:@"admin" forKey:@"username"]; [dictionnary setObject:@"123456" forKey:@"password"]; NSError *error = nil; NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dictionnary options:kNilOptions error:&error]; NSString *urlString = @"Sample URL"; NSURL *url = [NSURL URLWithString:urlString]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; [request setHTTPMethod:@"POST"]; [request setHTTPBody:jsonData]; NSURLResponse *response = NULL; NSError *requestError = NULL; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&requestError]; NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding] ; NSLog(@"%@", responseString);
如果它是一个GET请求，那么你可以尝试链接： /index.php/api/transaction/model/transactionsuccess?username=admin&password=1212 3
NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"/index.php/api/transaction/model/transactionsuccess?username=admin&password=12123"]]; // Perform request and get JSON as a NSData object NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; NSLog(@"response=%@",response );
并使用此代码。
这个问题与服务器端有关; 所以你必须咨询服务的后端开发者，更可能的是，在服务端检查使用POST或GET的数据命中，而如果后端是php，所以暂时build议他使用$ request而不是$得到或$后，只是为了testing。 另外，这个事实很明显，正如你所提到的那样，当你从浏览器中尝试url时，你得到了所需的json，但是在POST的情况下，你永远无法做到这一点。
我100％肯定这是从服务器端。如果可能的话提供我所需的服务器url与testingauthenticationvariables。 （通过断点或日志，通过参数交叉检查完整的url。）
