Question

每当我运行此函数时，我都会收到断言错误，我应该怎么做

   [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];
             }];

我收到此错误

*由于未捕获的异常'NSInternalInconsistencyException'而终止应用程序，原因：'无效的参数不满足：URLString' * 首先抛出调用堆栈：

Answer 1

你需要添加这行代码以避免无效的参数url string

 NSString *encoded = [link stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

Answer 2

（可为空的NSString *）stringByAddingPercentEscapesUsingEncoding：（NSStringEncoding）enc NS_DEPRECATED（10_0,10_11,2_0,9_0，＆＃34;使用   -stringByAddingPercentEncodingWithAllowedCharacters：相反，它始终使用推荐的UTF-8编码，并编码为   特定的URL组件或子组件，因为每个URL组件或   子组件对于哪些字符有效具有不同的规则。＆＃34;）;

@NullData回答此时工作完美，但方法stringByAddingPercentEscapesUsingEncoding已弃用，所以你们应该考虑使用stringByAddingPercentEncodingWithAllowedCharacters方法。

对于swift来说，这是一样的

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

或对于objc

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

Answer 3

可能是url地址不正确，有空格，错误字符等。例如：

断言失败 - [AFHTTPRequestSerializer requestWithMethod：URLString：parameters：error：]
