Question

但是在webview上没有显示任何内容。我已经检查过我正在尝试加载的html在浏览器上完美运行。

一切正常接受我遇到的XMLHttpRequest无法加载的一个状态... Access-Control-Allow-Origin错误不允许原点。

MainActivity.java：

    package com.example.gowsample;

    import android.annotation.TargetApi;
    import android.app.Activity;
    import android.os.Build;
    import android.os.Build.VERSION_CODES;
    import android.os.Bundle;
    import android.util.Log;
    import android.view.Menu;
    import android.view.MenuItem;
    import android.webkit.ConsoleMessage;
    import android.webkit.WebChromeClient;
    import android.webkit.WebSettings;
    import android.webkit.WebView;
    import android.webkit.WebViewClient;
    public class MainActivity extends Activity {
         private WebView mWebview ;

         @SuppressLint("SetJavaScriptEnabled") @TargetApi(Build.VERSION_CODES.JELLY_BEAN) @Override
            protected void onCreate(Bundle savedInstanceState) {
                    super.onCreate(savedInstanceState);
                    setContentView(R.layout.activity_main);
                    mWebview  = (WebView)findViewById(R.id.webView1);
                    mWebview.getSettings().setJavaScriptEnabled(true);
                    mWebview.getSettings().setDomStorageEnabled(true);
                    mWebview.getSettings().setAllowFileAccess(true);
                    mWebview.getSettings().setAllowContentAccess(true);
                    mWebview.getSettings().setAllowFileAccessFromFileURLs(true);
                    mWebview.getSettings().setAllowUniversalAccessFromFileURLs(true);
                    mWebview.setWebChromeClient(new WebChromeClient());         

    String myvar = ""; 

    String summary = "<!DOCTYPE html><html><meta http-equiv=\"content-type\" content=\"text/html; charset=UTF-8\"><!-- Video.js 4 -->\n<link href=\"http://vjs.zencdn.net/4.12/video-js.css\" rel=\"stylesheet\">\n<script src=\"http://mysite/video.js\"></script>\n<!-- Common -->\n<link href=\"http://mysite/bin/videojs.vast.vpaid.min.css\" rel=\"stylesheet\">\n<!-- Video.js 5 -->\n<script src=\"http://mysite/bin/videojs_4.vast.vpaid.min.js\"></script>\n<script src=\"http://mysite/VPAID1/bin/es5-shim.js\"></script>\n<script src=\"http://mysite/VPAID1/bin/ie8fix.js\"></script>\n<video id=\"example_video_1\" class=\"video-js vjs-default-skin\"\n    controls preload=\"auto\" width=\"300\" height=\"250\"\n    poster=\"http://vjs.zencdn.net/v/oceans.png\"\n    data-setup='{\n      \"plugins\": {\n      \"vastClient\": {\n        \"adTagUrl\": \"http://mysite/VPAID1/sincity.xml\",\n        \"adCancelTimeout\": 5000,\n        \"adsEnabled\": true\n        }\n      }\n    }'>\n  <source src=\"http://vjs.zencdn.net/v/oceans.mp4\" type='video/mp4'/>\n\n \n</video>\n</html>";
    String html =summary; 
    mWebview.loadData(html, "text/html; charset=utf-8", "UTF-8");

            }

    }

控制台说：

08-03 11：38：17.961：I / chromium（2858）：[INFO：CONSOLE（0）] “XMLHttpRequest无法加载 http://mysite/VPAID1/sincity.xml。一张通配符 '*'不能在'Access-Control-Allow-Origin'标题中使用凭证标志为真。因此不允许原点'null' 访问“，

如何解决这个错误..

当凭证标志为真时，Android Webview“XMLHttpRequest无法加载<xmlurl> .wildcard'*'无法使用'Access-Control-Allow-Origin'标头”
