我想使用webview发出http发布请求。
webView.setWebViewClient(new WebViewClient(){
public void onPageStarted(WebView view, String url,
Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
public boolean shouldOverrideUrlLoading(WebView view,
String url) {
webView.postUrl(Base_Url, postData.getBytes());
return true;
}
});
上面的代码段加载了网页。我想访问此请求的响应。
如何使用webview获取http post请求的响应?
提前致谢
WebView不允许您访问HTTP响应的内容。
您必须使用HttpClient,然后使用函数loadDataWithBaseUrl并指定基本URL将内容转发到视图,以便用户可以使用webview继续在网站中导航。
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);
首先将http库的支持添加到您的gradle文件:能够使用
useLibrary 'org.apache.http.legacy'
在此之后,您可以使用以下代码在webview中执行发布请求:
public void postUrl (String url, byte[] postData)
String postData = "submit=1&id=236";
webview.postUrl("http://www.belencruzz.com/exampleURL",EncodingUtils.getBytes(postData, "BASE64"));
