AFnetworking回头率响应代码= -1011“请求失败：客户端错误（422）

Question

我尝试使用AFNetworking创建一个POST请求但是我始终返回错误说：

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 {

这里我的代码：

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 { 

} 

我小我肯定提供了（主题，说明，电子邮件）的参数是corrent，监守如果我把参数直接像下面的网址，它工作正常

https://isisfriends.zendesk.com/requests/mobile_api/create.json?subject=testing&email=testing@asd.com&description=testing

422客户端错误是由于验证失败。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，以检查服务器对您的呼叫所说的话。

使用这种简化代码：

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); 


    }]; 

希望这有助于。
