好吧,我正在尝试在外部服务器上授权我的 android 应用程序,首先我加载用户输入其用户名和密码的 URL,然后该页面将我重定向到我的页面上并向我发送我应该获取的“代码”和“状态”授权令牌。我正在尝试使用检索该代码,JavascriptInterface
但不幸的是没有收到任何东西......所以有一个问题,为什么我没有得到代码或状态?
一些编码:
我的安卓端:
@SuppressLint("SetJavaScriptEnabled")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.web_view);
web_view = (WebView) findViewById(R.id.web_view);
web_view.getSettings().setJavaScriptEnabled(true);
web_view.addJavascriptInterface(new IJavascriptHandler(this),
"AndroidBridge");
final AlertDialog alertDialog = new AlertDialog.Builder(this).create();
progressBar = ProgressDialog.show(LoginActivity.this,
"Authentication", "Loading...");
web_view.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
public void onPageFinished(WebView view, String url) {
if (progressBar.isShowing()) {
progressBar.dismiss();
}
}
public void onReceivedError(WebView view, int errorCode,
String description, String failingUrl) {
alertDialog.setTitle("Error");
alertDialog.setMessage(description);
alertDialog.setButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int which) {
return;
}
});
alertDialog.show();
}
});
web_view.loadUrl(authorizationURL);
}
public class IJavascriptHandler {
LoginActivity activity;
public IJavascriptHandler(LoginActivity activity) {
this.activity = activity;
}
@JavascriptInterface
public void sendToAndroid(String code, String state) {
// this is called from JS with passed value
try {
Log.v("LOGIN CODE + state", code + " " + state);
} catch (Exception e) {
Log.v("LOGIN ERROR", ":(");
e.printStackTrace();
}
}
}
网页端:
<?php
if(isset($_GET['code'])){
echo "<html>
<body>
<script type=\"text/javascript\">
if(window.AndroidBridge){
window.AndroidBridge.sendToAndroid(" . $_GET["code"] . ", " . $_GET["state"] . ");
}
else {
alert(\"Error\");
}
</script>
<p>Success!</p>
<p>" . $_GET["code"] . "</p>
<p>" . $_GET["state"] . "</p>
</body>
</html>
";
}
?>
注意:此页面上有一些打印 html,所以我得到了代码和状态,但是函数 sendToAndroid 不能正常工作,或者我的 Java 中的某些东西......这两个if
条件都是正确的。
