Delight-im高级网络视图通过每个GET&发送自定义标头POST请求 [英] Delight-im advanced webview send custom headers with every GET & POST request
本文介绍了Delight-im高级网络视图通过每个GET&发送自定义标头POST请求的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在使用delight-im/Android-AdvancedWebView加载带有附加标头(用户身份验证令牌)的网址，但标头仅在初始请求时发送，即该Webview所加载的第一个网址.但是，当我单击该URL中的另一个链接并尝试发布一些值时，标题未传递.如何将其扩展为具有与基本url相关联的url的所有GET和POST请求? 请提及一种执行此操作的方法. 这是我的代码示例，用于通过webview加载网址.
I am using delight-im/Android-AdvancedWebView for loading a url with extra headers (user auth token), but the headers are sending only with the initial request, that is the first url the webview is loading. But when I click another link in that url and try to POST some value the header is not passed along. How it can be extended to all GET and POST requests with the url's associated with base url ? Please mention a way to do this. Here is my code sample for loading the url with webview.
public class TableViewTest extends AppCompatActivity implements AdvancedWebView.Listener {
SharedPreferences pref;
boolean preventCaching = true;
private static final String URL = "my-url";
private AdvancedWebView mWebView;
@SuppressLint("SetJavaScriptEnabled")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_table_view_test);
pref = getSharedPreferences("LoginActivity", Context.MODE_PRIVATE);
final String acToken = pref.getString("token", "DEFAULT");
//used this method to add headers with every request, not working
Map<String, String> headers = new HashMap<String, String>();
headers.put("Authorization", "Bearer " + acToken);
//mWebView.loadUrl(your url, headers);
//webView = (WebView) findViewById(R.id.webView1Id);
mWebView = (AdvancedWebView) findViewById(R.id.webview);
mWebView.setListener(this, this);
mWebView.setGeolocationEnabled(false);
mWebView.setMixedContentAllowed(true);
mWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);

}
mWebView.setWebViewClient(new WebViewClient() {

});
mWebView.setWebChromeClient(new WebChromeClient() {

super.onReceivedTitle(view, title);

}*/
}
@Override

}
@Override
protected void onSaveInstanceState(Bundle outState) {

webView.saveState(outState);

推荐答案
您可以添加以下代码:
mWebView.setWebViewClient(new WebViewClient(){
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url, getExtraHeaders());
return true;
}
});
其中getExtraHeaders()返回一个Map<String, String>，其中包含要在此URL的HTTP请求中使用的其他标头.
where getExtraHeaders() returns a Map<String, String> containing the additional headers to be used in the HTTP request for this URL.
另外，请注意，addHttpHeader现在已得到修复，并随每个GET请求发送自定义标头.
Also, please note that addHttpHeader has been fixed now and sends custom headers with every GET request.
