Delight-im高级WebView如何在每个GET和POST请求中发送自定义标头？

Question

我正在使用delight-im/Android-AdvancedWebView来加载带有额外标头（用户身份验证令牌）的url，但是这些标头仅随初始请求发送，即WebView加载的第一个url。但是，当我单击该url中的另一个链接并尝试POST一些值时，标头不会被传递。如何将其扩展到所有与基本url相关联的GET和POST请求的url上？ 请提供一种解决方法。 以下是用于使用WebView加载url的代码示例。

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);

Answer 1

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;
    }
});

getExtraHeaders() 返回一个包含用于此 URL 的 HTTP 请求中使用的附加标头的 Map<String, String>。

另外，请注意，addHttpHeader 已经修复，现在会在每个 GET 请求中发送自定义标头。
