一直在努力改变在一个Android应用程序的HTTP请求的用户代理字符串。我已经使用Wireshark和仿真器一起进行了测试,已经看出,虽然我设置了用户代理字符串中的web视图,相关的使用loadURL请求不使用此用户代理字符串。相反,我看到的Wireshark捕获的Dalvik用户代理字符串。这里是code抽象。有任何想法吗?还是模拟器不支持此?
@覆盖公共无效的run(){ 断言(上下文!= NULL); ... ... web视图=新的WebView(背景); ... 字符串defaultUserAgent =betaUAteststring; //清除每个应用程序缓存等 webView.clearCache(真); webView.clearHistory(); webView.getSettings()setAppCacheEnabled(假)。 。webView.getSettings()setCacheMode(WebSettings.LOAD_NO_CACHE); webView.getSettings()setJavaScriptEnabled(真)。 webView.setWebViewClient(新WebViewClient(){ @覆盖 公共无效onPageFinished(的WebView视图,字符串URL){ .... } @覆盖 公共无效onPageStarted(的WebView视图,字符串URL,位图图标){ .. } @覆盖 公共无效onLoadResource(的WebView视图,字符串URL){ ... } }); //开始加载 。webView.getSettings()setUserAgentString(defaultUserAgent); 字符串setUA = webView.getSettings()getUserAgentString()。 // - >这里记录显示正确的用户代理,所以web视图不接受该值 //但下面的语句不会导致与网页视图用户代理HTTP请求 webView.loadUrl(URL); //替代无助或者(且不应根据的Javadoc) //地图<字符串,字符串> headerMap =新的HashMap<字符串,字符串>(); //headerMap.put(\"User-Agent\",\"uaTestInAMap); //webView.loadUrl(url,headerMap);}
解决方案
回答我的问题。看来,不论什么原因,仿真器不采取从web视图用户代理字符串。我还没有发现这不过的理由。在code正常工作的真实设备上。
Been trying to change the User-Agent string in the HTTP request of an Android app. I have tested this together with wireshark and the emulator, and have seen that although I set the useragent string in the webview, the associated loadUrl request does not use this user-agent string. Instead I see the Dalvik useragent string in the wireshark capture. Here is the code abstract. Any ideas? Or does the emulator not support this?
@Override
public void run() {
assert(context != null);
...
...
webView = new WebView(context);
...
String defaultUserAgent = "betaUAteststring";
// Clear per-application caches etc
webView.clearCache(true);
webView.clearHistory();
webView.getSettings().setAppCacheEnabled(false);
webView.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient() {
@Override
public void onPageFinished(WebView view, String url) {
....
}
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
..
}
@Override
public void onLoadResource(WebView view, String url) {
...
}
});
// Start loading
webView.getSettings().setUserAgentString(defaultUserAgent);
String setUA = webView.getSettings().getUserAgentString();
//--> logging here shows the correct user agent, so the webview does accept the value
// However the following statement does not result in an http request with the webviews user agent
webView.loadUrl(url);
//Alternative doesn't help either (and shouldn't according to javadoc)
//Map<String,String> headerMap = new HashMap<String,String>();
//headerMap.put("User-Agent","uaTestInAMap");
//webView.loadUrl(url, headerMap);
}
解决方案
Answering my own question. It appears that the emulator for whatever reason is not taking the user agent string from the webview. I have not found out the reason for this however. The code works fine on a real device.
