使用Android webView访问html页面，碰到ajax跨域访问时，仅仅在header中加入

http {

......

add_header Access-Control-Allow-Origin *;

add_header Access-Control-Allow-Headers X-Requested-With;

add_header Access-Control-Allow-Methods GET,POST,OPTIONS;

......

}

信息，无法解决跨域访问问题，可以尝试给webview设置如下配置，已解决该问题；

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN){

webView.getSettings().setAllowUniversalAccessFromFileURLs(true);

}else{

try {

Class> clazz = webView.getSettings().getClass();

Method method = clazz.getMethod("setAllowUniversalAccessFromFileURLs", boolean.class);

if (method != null) {

method.invoke(webView.getSettings(), true);

}

} catch (NoSuchMethodException e) {

e.printStackTrace();

} catch (InvocationTargetException e) {

e.printStackTrace();

} catch (IllegalAccessException e) {

e.printStackTrace();

}

}
