Android Development (30) Use WebView and click the link on the webpage to create a temporary QQ session WPA

On the PC end, We can click a URL link to start QQ. This is a good user jump experience. Very convenient.

The links used are as follows:

<A target = "_ blank" href = "http://wpa.qq.com/msgrd? V = 3 & uin = & site = qq & menu = yes"
> Click </a>

Replace 8888888 with your QQ number.

webView1.setWebViewClient(new WebViewClient() {public boolean shouldOverrideUrlLoading(WebView view, String url) {view.loadUrl(url);return true;}});

After capturing the sent request packet, I found that in the request of the http://wpa.qq.com, the actual request was also sent starting with mqqwpa: // im/chat.

Therefore, you need to overload the shouldInterceptRequest method to intercept other sechme processes.

 

As shown below:

webView1.setWebViewClient(   (url.startsWith("http") || url.startsWith("https" =
