Android Webview POST [英] Android Webview POST

问题描述

我试图完成一些非常简单的事情，但我没有找到关于此的好的文档.我有一个 webView，我需要在其中加载一个需要 POST 数据的页面.看起来是一个简单的过程，但我找不到在 webView 中显示结果的方法.

I am trying to accomplish something quite simple, yet I have found no good documentation on this. I have a webView, and I need to load a page in it that requires POST data. Seems like a simple process, yet I cannot find a way to display the result in a webView.

过程应该很简单:

query(with POST data) -> webserver -> HTML response -> WebView.

query(with POST data) -> webserver -> HTML response -> WebView.

我可以使用 DefaultHttpClient 提交数据，但无法在 WebView 中显示.

I can submit data using a DefaultHttpClient, but this cannot be displayed in a WebView.

有什么建议吗?

非常感谢

解决方案

private static final String URL_STRING = "http://www.yoursite.com/postreceiver";

    public void postData() throws IOException, ClientProtocolException {  

         List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();  
         nameValuePairs.add(new BasicNameValuePair("foo", "12345"));  
         nameValuePairs.add(new BasicNameValuePair("bar", "23456"));

         HttpClient httpclient = new DefaultHttpClient();  
         HttpPost httppost = new HttpPost(URL_STRING);  
         httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));  

         HttpResponse response = httpclient.execute(httppost);  
         String data = new BasicResponseHandler().handleResponse(response);
         mWebView.loadData(data, "text/html", "utf-8");
    }

推荐答案

试试这个:

private static final String URL_STRING = "http://www.yoursite.com/postreceiver";

public void postData() throws IOException, ClientProtocolException {  

     List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();  
     nameValuePairs.add(new BasicNameValuePair("foo", "12345"));  
     nameValuePairs.add(new BasicNameValuePair("bar", "23456"));

     HttpClient httpclient = new DefaultHttpClient();  
     HttpPost httppost = new HttpPost(URL_STRING);  
     httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));  

     HttpResponse response = httpclient.execute(httppost);  

}

我建议将此作为 AsyncTask 的一部分并在之后更新 WebView

I would recommend doing this as part of an AsyncTask and updating the WebView afterwards
