我正在尝试以键值对的形式阅读jSON响应。
当我通过浏览器手动点击网址时，我通过jSON对象获取所需的状态代码/响应
{"status":"0","responseCode":"1021","response":{"message":"Please check your Settings ","data":"2012-11-24, 7:28 am"}}
当我尝试通过我的app.My代码通过应用程序发送数据时，无法获得相同的预期响应
[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);
我通过代码获得的回复

答案 0 :(得分：1)
- (void)requestFinished:(ASIHTTPRequest *)request1
{
// Use when fetching text datatype = agency; type = court;
NSString *responseString = [request1 responseString];
}
- (void)requestFailed:(ASIHTTPRequest *)request1
{
NSError *error = [request1 error];
NSLog(@"%@",error);
}
这些是ASIHttp方法的委托方法。将在响应到来时调用。
快乐编码!!!!
答案 1 :(得分：0)
请注意ASIHTTPRequest no longer working因此您可以使用AFNetworking。
AFNetworking是iOS和Mac OS X的令人愉快的网络库。它建立在NSURLConnection，NSOperation和其他熟悉的Foundation technologies之上。它有一个modular architecture，设计精良，功能丰富的API非常适合使用。
找到SDK here
此外，您可以尝试以下代码可能会帮助您。
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);
如果是GET请求，那么您可以尝试链接： /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。
