Question

我正在使用ASIHTTPRequest [request startAsynchronous]功能向我的webservice api发送请求以登录。如果请求正常，则返回json值。然后我发送另一个请求以获取用户的信息，但在这里我收到错误。

这是我的代码：

-(void)login
{
    [usernameTextField resignFirstResponder];
    [passwordTextField resignFirstResponder];

    username = [usernameTextField text];
    password = [passwordTextField text];

    if ( ([username length] == 0 ) || ([password length] == 0 )) 
    {
       ...
    }
    else
    {
        NSString *URL = [NSString stringWithFormat:@"https://xxx.xxx.xx.xx/FMS/Pages/Service/FMService.svc/Login?user=%@&pass=%@",username,password];
        NSURL *requestURL = [NSURL URLWithString:URL];
        ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:requestURL];
        [request setValidatesSecureCertificate:NO];
        [request setDelegate:self];
        [request startAsynchronous];
    }
}

- (void)requestFinished:(ASIHTTPRequest *)request
{
    NSError *error = [request error];
    if (!error) 
    {
        NSString *responseString = [request responseString];
        NSDictionary *responseDict = [responseString JSONValue];
        NSString *unlockCode = [responseDict objectForKey:@"d"];
        if ( [unlockCode isEqualToString:@"successful"] ) 
        {
            NSURL *url = [NSString stringWithFormat:@"https://xxx.xxx.xx.xx/FMS/Pages/Service/FMService.svc/GetUserInfo?user=%@",username];
            ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
            [request setValidatesSecureCertificate:NO];
            [request startSynchronous];**//THERE IS AN ERROR**
            NSError *error = [request error];
            if (!error) 
            {
                NSDictionary *responseDict = [responseString JSONValue];
                NSString *realName = [responseDict objectForKey:@"RealName"];
                NSLog(@"%@",realName);
            } 
        }
        else
        {
           //...
        }
    }
    else
    {
        NSLog(@"%@",[error description]);
    }
}

有一个错误：

[__ NSCFString absoluteURL]：发送到实例的无法识别的选择器 0x69ef4b0

另一个错误：

void SendDelegateMessage（NSInvocation *）：delegate （_selectionLayoutChangedByScrolling :)等待后无法返回 10秒主运行循环模式：kCFRunLoopDefaultMode

此行不正确：

    NSURL *url = [NSString stringWithFormat:@"https://xxx.xxx.xx.xx/FMS/Pages/Service/FMService.svc/GetUserInfo?user=%@",username];

应该改为：

    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"https://xxx.xxx.xx.xx/FMS/Pages/Service/FMService.svc/GetUserInfo?user=%@",username]];
