Question

我试图创建一个应用程序来保存来自特定网站（https://www.airservicesaustralia.com/naips/Account/LogOn）的网页，并且我试图让应用为用户登录，并提供他们在应用中保存的详细信息。我想尝试让它在后台发布登录数据。我一直在尝试使用NSMutableURLRequest，但没有运气......有关如何在后台登录此网站的任何建议吗？

谢谢！

Answer 1

您应该使用具有某种开发模式的浏览器（例如启用了开发人员模式的Chrome或Safari）并读取登录时发生的POST或GET请求中的变量（在这种情况下，发生时发生的请求）你按Submit）。

在您自己的请求中使用相同的变量。

将其放入“登录”按钮操作

NSString *post = [[NSString alloc] initWithFormat:@"uname=%@&pwd=%@",usernameData,passwordData];

NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];

NSURL *url = [NSURL URLWithString:@"http://www.yourlink.com/chckLogin.php"];
NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
[theRequest setHTTPMethod:@"POST"];
[theRequest setValue:postLength forHTTPHeaderField:@"Content-Length"];
[theRequest setHTTPBody:postData];


NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

if( theConnection )
{
    indicator.hidden = NO;
    [indicator startAnimating];
    webData = [[NSMutableData data] retain];
}
else
{
    NSLog(@"Internet problem maybe...");
}

然后有连接

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    [webData setLength: 0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
    [webData appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
    // show error
    indicator.hidden = YES;
    [indicator stopAnimating];
    [connection release];
    [webData release];
}

-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    NSString *loginStatus = [[NSString alloc] initWithBytes: [webData mutableBytes] length:[webData length] encoding:NSUTF8StringEncoding];
    greetingLabel.text = @"";
    NSLog(@"after compareing data is %@", loginStatus);
    if ([loginStatus isEqualToString:@"right"]) {

        // right login
    } else {
        // wrong login
        greetingLabel.hidden = NO;
        greetingLabel.text = @"Incorrect username and/ or password.";
    }

    [loginStatus release];
    [connection release];
    [webData release];
    indicator.hidden = YES;

}
