WebView作为嵌入浏览器进行OAuth1.0认证

来源：互联网发布：电脑数据流量统计编辑：程序博客网时间：2024/06/01 07:31

新浪微博Android客户端开发视频中OAuth认证要使用WebView作为嵌入浏览器进行OAuth认证，所以现在我也把代码贴出来一下

首先是布局文件，webview.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<WebView android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/wbView"/>
</LinearLayout>

复制代码

布局文件比较简单，就一个WebView 控件。

Activity：

package com.iweibo;
import com.iweibo.oauth.MyOAuth;
import com.iweibo.util.JavascriptInterface;
import android.app.Activity;
import android.app.ProgressDialog;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Toast;
/**

* @version 1.0

*/
public class WebViewActivity extends Activity {
private WebView wbView;
private String url=null;
private Handler handler;
private ProgressDialog pd;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
url= MyOAuth.getAuthenticationURL();
System.out.println("url" +url);
if(null==url)
{
Toast.makeText(this, "授权地址为空", 3000).show();
return ;
}
init();
loadUrl(wbView, url);
handler = new Handler()
{
public void handleMessage(android.os.Message msg)
{
switch(msg.what)
{
case 0:
pd.show();
break;
case 1:
pd.dismiss();
break;
}
};
};
}
private void init()
{
wbView = (WebView) this.findViewById(R.id.wbView);
//设置可用Javascript脚本
wbView.getSettings().setJavaScriptEnabled(true);
wbView.setScrollBarStyle(0);//滚动条风格，为0就是不给滚动条留空间，滚动条覆盖在网页上
wbView.addJavascriptInterface(new JavascriptInterface(), "Methods");
wbView.setWebViewClient(new WebViewClient()
{
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
loadUrl(view, url);
return true;
}
@Override
public void onPageFinished(WebView view, String url)
{
if(url.equals("http://api.t.sina.com.cn/oauth/authorize"))
{
view.loadUrl("javascript:window.Methods.getPin('<head>'+document.getElementsByTagName('html')[0].innerHTML+'</head>');");
Intent intent = new Intent(WebViewActivity.this, AccessTokenActivity.class);
startActivity(intent);
}
super.onPageFinished(view, url);
}
});
wbView.setWebChromeClient(new WebChromeClient(){
public void onProgressChanged(WebView view, int newProgress)
{
if(newProgress == 100)// 全部加载完毕
{
handler.sendEmptyMessage(1);
}
super.onProgressChanged(view, newProgress);
}
});
pd = new ProgressDialog(this);
pd.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pd.setMessage("正在载入");
}
private void loadUrl(final WebView view,final String url)
{
new Thread()
{
public void run() {
handler.sendEmptyMessage(0);
view.loadUrl(url);
};
}.start();
}
}
