Android的登录网站 - 总是返回登录页面数据 [英] Android Login to Website - Always returns login page data

问题描述

我有一个登录表单目前正在登录参数，并登录到使用HTTP POST请求一个网站。我不确定服务器类型，这样可能是问题。一旦需要登录凭据，它覆羽InputStream的一个字符串（所有的HTML），并设置到一个TextView。这里的登录：

I have a login form currently taking login parameters and logging into a website using HTTP Post Request. I am unsure of the server type so that could be the problem. Once it takes the login credentials, it coverts the inputstream to a string (all the html) and sets that to a textview. Here's the login:

private void postLoginData() throws ClientProtocolException, IOException {
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost("loginurl"); // Changed for question.

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("sid", "username"));
        nameValuePairs.add(new BasicNameValuePair("pin", "pass"));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);
        String finalres = inputStreamToString(response.getEntity().getContent()).toString();
        tvStatus.setText(finalres);

    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
    } catch (IOException e) {
        // TODO Auto-generated catch block
    }
}

和这里的inputStreamToString（）

And here's the inputStreamToString()

private StringBuilder inputStreamToString(InputStream is) throws IOException {
    String line = "";
    StringBuilder total = new StringBuilder();

    // Wrap a BufferedReader around the InputStream
    BufferedReader rd = new BufferedReader(new InputStreamReader(is));

    // Read response until the end
    while ((line = rd.readLine()) != null) { 
        total.append(line); 
    }

    // Return full string
    return total;
}

问题是，它永远只是返回登录页面的HTML。当用户无法在网站上登录，它有一个小的消息来表示。即使我添加不正确的凭据，它不会显示任何不同。同样，如果我添加正确的登录，它仍然显示我刚登录页面的HTML。

The problem is that it ALWAYS just returns the HTML for the login page. When a user fails login on the site, it has a little message to indicate so. Even if I add incorrect credentials, it doesn't display anything different. Likewise, if I add the correct login, it still shows me just the login page HTML.
