ios - AFnetworking 不断返回响应代码=-1011“请求失败 : client error (422)

Question

我正在尝试使用 AFNetworking 创建 POST 请求。但是我总是返回一个错误说:

    Error Domain=com.alamofire.error.serialization.response Code=-1011 "Request failed: client error (422)" UserInfo=0x7ff1fa76a5c0 {com.alamofire.serialization.response.error.response=<NSHTTPURLResponse: 0x7ff1fa76ce40> { URL: https://isisfriends.zendesk.com/requests/mobile_api/create.json } { status code: 422, headers {

} }, NSErrorFailingURLKey=https://isisfriends.zendesk.com/requests/mobile_api/create.json, com.alamofire.serialization.response.error.data=<7b226572 726f7222 3a22496e 76616c69 6420656d 61696c20 61646472 65737322 7d>, NSLocalizedDescription=Request failed: client error (422)}

这是我的代码:

NSString * question = [_textFieldQuestion text];
NSString * detail = [_textFieldDetails text];
NSString * email = [_textFieldEmail text];

if(question.length > 0 && detail.length > 0 && email.length > 0)
{
    NSString *url = @"https://isisfriends.zendesk.com/requests/mobile_api/create.json";
    NSDictionary *parameters = @{@"subject":question, @"description":detail, @"email":email};


    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];


    AFJSONRequestSerializer *reqSerializer = [AFJSONRequestSerializer serializer];
    [reqSerializer setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [reqSerializer setValue:@"1.0" forHTTPHeaderField:@"X-Zendesk-Mobile-API"];


    manager.requestSerializer = reqSerializer;
    manager.responseSerializer = [AFJSONResponseSerializer serializer];

    NSLog(parameters.descriptionInStringsFileFormat);

    [manager POST:url parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) {
        NSLog(@"===== JSON: ======= %@", responseObject);
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"============== Error: ============\n%@", [error description]);
    }];


} else {

}

我很确定我提供的参数(主题、描述、电子邮件)是正确的，因为如果我像下面这样将参数直接放在 url 中，它就可以正常工作。

422 客户端错误是由于身份验证失败。检查您是否需要任何身份验证，或者如果您认为您有权限，请在控制台中查找记录的 Failure error serialised 以检查服务器必须对您的调用说些什么。

使用这个简化的代码:

    NSString *myUrlString= YOUR LINK;

    NSMutableDictionary* postRequestDictionary = [[NSMutableDictionary alloc] init];

    postRequestDictionary[@"YOUR PARAMATER"]= YOUR PARAMETER VALUE;

 //  ... ADD ANY MORE PARAMETER IF YOU WANT HERE ...

    NSLog(@"body = %@",postRequestDictionary);

    AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager alloc]init];

    manager.responseSerializer = [AFJSONResponseSerializer serializer];
    manager.requestSerializer = [AFJSONRequestSerializer serializer];
    [manager.requestSerializer setValue:@"HEADER VALUE" forHTTPHeaderField:@"HEADER"];

 //   ... ADD ANYMORE HEADER IF YOU WANT ...


    [manager POST:myUrlString parameters:postRequestDictionary success:^(AFHTTPRequestOperation *requestOperation,id JSON){

        NSLog(@"%@",JSON);


    } failure:^(AFHTTPRequestOperation *requestFailureOperation , NSError *error){


        NSLog(@"%@",error);
        NSData *errorData = error.userInfo[AFNetworkingOperationFailingURLResponseDataErrorKey];

        NSDictionary *serializedData = [NSJSONSerialization JSONObjectWithData: errorData options:kNilOptions error:nil];
        NSLog(@"Failure error serialised - %@",serializedData);


    }];

希望这对您有所帮助。 😊👍
