Objective c 带有URL参数的断言失败

在我的项目中，我需要向客户端发送电子邮件，但我面临断言失败和无效参数。我已经检查了所有的解决方案，但都不起作用

-(void)EmailWebservice
{
    [MBProgressHUD showHUDAddedTo:self.view animated:YES];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
    [serializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [serializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    manager.requestSerializer = serializer;

    NSString *getPostLink = [NSString stringWithFormat:@"http://Dummy.com/sendmail/?business_email=%@&_name=%@",TextEmail.text,[[NSUserDefaults standardUserDefaults]valueForKey:@"USERNAME"]];

    NSString *encoded = [getPostLink stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    NSLog(@"Encoding value is %@",encoded);

    [manager GET:getPostLink parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

        NSLog(@"JSON: %@", responseObject);
        [MBProgressHUD hideHUDForView:self.view animated:YES];

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

        NSLog(@"the failure is %@", error);
        [MBProgressHUD hideHUDForView:self.view animated:YES];

    }];
}

错误：

由于未捕获异常而终止应用程序 'NSInternalInconsistencyException'，原因：'无效参数不存在 令人满意的：URLString'

错误是告诉您的URL有问题。我会先打印出url，就像您使用该行所做的那样：

NSLog(@"Encoding value is %@",encoded);

你能把它粘贴到你选择的浏览器中，看看页面是否加载吗

您可能正在尝试对url中的参数值进行硬编码：

business_email
fave_customer_name

对参数进行编码：

-(void)EmailWebservice
{
    [MBProgressHUD showHUDAddedTo:self.view animated:YES];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer];
    [serializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [serializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    manager.requestSerializer = serializer;

    NSString *email = [TextEmail.text stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    NSString customer = [[NSUserDefaults standardUserDefaults]valueForKey:@"USERNAME"] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    NSString *getPostLink = [NSString stringWithFormat:@"http://Dummy.com/csrestapi/sendintroemail/?business_email=%@&fave_customer_name=%@",email,customer];

    NSString *encoded = [getPostLink stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    NSLog(@"Encoding value is %@",encoded);

    [manager GET:getPostLink parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

        NSLog(@"JSON: %@", responseObject);
        [MBProgressHUD hideHUDForView:self.view animated:YES];

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

        NSLog(@"the failure is %@", error);
        [MBProgressHUD hideHUDForView:self.view animated:YES];

    }];
}
