推荐答案

WebView 不允许您访问 HTTP 响应的内容.

The WebView does not let you access the content of the HTTP response.

为此，您必须使用 HttpClient，然后使用 loadDataWithBaseUrl 并指定基本 url，以便用户可以使用 webview继续在网站中导航.

You have to use HttpClient for that, and then forward the content to the view by using the function loadDataWithBaseUrl and specifying the base url so that the user can use the webview to continue navigating in the website.

示例:

// Executing POST request
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(url);
httppost.setEntity(postContent);
HttpResponse response = httpclient.execute(httppost);

// Get the response content
String line = "";
StringBuilder contentBuilder = new StringBuilder();
BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
while ((line = rd.readLine()) != null) { 
    contentBuilder.append(line); 
}
String content = contentBuilder.toString();

// Do whatever you want with the content

// Show the web page
webView.loadDataWithBaseURL(url, content, "text/html", "UTF-8", null);
