Question

所以我正在制作一个测试登录应用程序，所以我可以看看应用程序和服务器如何一起表现。所以我有三个与我合作的端点。所有三个下载json文件，所以我可以打印出来没问题。问题是它们都需要用户名和密码。我得到了第一个没有问题的下载，它完美无缺。我在我的httpClass中使用内置验证器的机器人来处理这个问题。我所要做的就是将我的用户名和密码传递给它，它的工作正常。

另一个端点将检查用户是否可以登录服务器。这也会返回一个json。它还需要用户名和密码。但它不适用于我用于第一个的验证器。它一直给我filenotfound异常和它。唯一希望我能让这个工作的是构建url并将其发送到httpclass。通过手动添加像这样的用户名和密码

http://mywebpage/endpoint1

然后添加像这样的信息

http://mywebpage/endpint2

我是用代码手动完成的。我不认为这是正确的方法，因为我工作的第一个看起来是正确的方式。任何建议，将不胜感激。

这是我正在使用的html类

public class MyHttpClass extends AsyncTask<String, Void, String> {

private String user;
private String pass;
Activity act;

//this is used if you need a password and username
//mainly for logins to a webserver
public MyHttpClass(String user, String pass)
{
    this.user = user;
    this.pass = pass;

}

@Override
protected String doInBackground(String... params) {
        String url = params[0];
        return http(url);
}
private String http(String myUrl)

{
    String respone = null;
    HttpURLConnection urlConnection = null;
    try
    {
        URL url = new URL(myUrl);
            Authenticator.setDefault(new Authenticator() {
                @Override
                protected PasswordAuthentication getPasswordAuthentication() {
                    return new PasswordAuthentication(user, pass.toCharArray());
                }
            });

        urlConnection = (HttpURLConnection)url.openConnection();

        InputStream inputStream = urlConnection.getInputStream();

        if(inputStream != null)
        {
            respone = streamToString(inputStream);
            inputStream.close();
        }

    }catch (IOException ie)
    {
        //ie.printStackTrace();
        Log.d("Issue with Http: " , "IOException");
        ie.printStackTrace();

    }finally {
        if(urlConnection != null)
        {
            urlConnection.disconnect();
        }
    }
    return respone;
}

这是我正在进行所有测试的主要课程

在android中使用Volley库。它与GSON一起用于发出自定义请求，因此您无需担心JSON创建和JSON解析。一切都很容易。
