断言失败 - [AFHTTPRequestSerializer requestWithMethod：URLString：参数：错误：]

每当我运行这个功能我得到断言错误，我应该怎么办断言失败 - [AFHTTPRequestSerializer requestWithMethod：URLString：参数：错误：]

[MBProgressHUD showHUDAddedTo:self.view animated:YES]; 
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; 
    NSString *link = [NSString stringWithFormat:@"%@device_model_no=%@&device_serial_no=%@&device_imei=%@&note=%@&disclaimer=%@&extra_note=%@&package_plan=%@&price=%@&duration=%@&device=%@&user_reg_id=%@&device_category=%@",KURL,txtModelNumber.text,txtSerialNo.text,txtIMEI.text,txtViewExtra.text,deviceDisclamer,additonalDetail.text,plan,price,duration,deviceName,userID,nil]; 
    NSLog(@"%@",link); 

    manager.responseSerializer.acceptableContentTypes = [manager.responseSerializer.acceptableContentTypes setByAddingObject:@"text/html"]; 

    [manager GET:link parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) { 
     NSLog(@"JSON: %@", responseObject); 


     NSLog(@"%@", responseObject); 

     NSDictionary *returnedDealDict = responseObject ; 
     NSArray *returnArray = [returnedDealDict objectForKey:@"result"]; 

     for(NSDictionary *dealDict in returnArray) 
     { 
      if ([dealDict objectForKey:@"success"]) 
      { 
       ALERT_VIEW(@"Thanks1! Your information has been saved Successfully! We will contact you soon.") 
      } 
      else 
      { 
       ALERT_VIEW(@"Your information doesn t exist in our database, Please go back and enter your contact info again!") 
      } 
     } 
     success(); 

     [MBProgressHUD hideHUDForView:self.view animated:YES]; 




    } 
     failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
      NSLog(@"Error: %@", error); 
      ALERT_VIEW(@"Error occured while loading data."); 
      NSLog(@"getBrandDevice Error"); 
      [MBPro 

gressHUD hideHUDForView:self.view animated:YES]; 
      }];

我得到这个错误

什么该网址最终会成为？ – borrrden 2014-09-25 05:50:54

你需要添加这行代码，以避免无效参数的URL字符串

NSString *encoded = [link stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

(nullable NSString *)stringByAddingPercentEscapesUsingEncoding:(NSStringEncoding)enc NS_DEPRECATED(10_0, 10_11, 2_0, 9_0, "Use -stringByAddingPercentEncodingWithAllowedCharacters: instead, which always uses the recommended UTF-8 encoding, and which encodes for a specific URL component or subcomponent since each URL component or subcomponent has different rules for what characters are valid.");

@NullData在这一刻完美的回答工作，但方法stringByAddingPercentEscapesUsingEncoding已过时的话，你们应该考虑到改为使用stringByAddingPercentEncodingWithAllowedCharacters方法。

像这样迅速

let path = myurlstring.stringByAddingPercentEncodingWithAllowedCharacters(NSCharacterSet.URLQueryAllowedCharacterSet())

或本作objc

path = [path stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
