How to get the body of the WebResourceRequest in android webView

I need to modify the request header of the android webView request. So, I add the following code in the method shouldInterceptRequest.

Here is my code:

@Override
public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
    try {
        String mUrl = request.getUrl().toString();
        OkHttpClient httpClient = new OkHttpClient();
        Request mRequest = new Request.Builder()
                .url(request.getUrl().toString())
                .addHeader("token", UserHelper.getToken()) //add headers
                .build();
        Response response = httpClient.newCall(mRequest).execute();

        return new WebResourceResponse(
            getMimeType(request.getUrl().toString()), // set content-type
            response.header("content-encoding", "utf-8"),
            response.body().byteStream()
        );
    } catch (Exception e) {
        return super.shouldInterceptRequest(view, request);
    }
    return super.shouldInterceptRequest(view, request);
}

Actually, it works, all the requests carry the new header. However, because I construct the new request, the original request method/body was lost. I don't know how to keep the original method and body from the WebResourceRequest.

WebResourceRequest is an interface that can't read the request body, but you can use your own interface something like this repo dose.

https://github.com/KonstantinSchubert/request_data_webviewclient

webView.setWebViewClient(new WriteHandlingWebViewClient() {
   @Override
   public boolean shouldOverrideUrlLoading(WebView view, WriteHandlingWebResourceRequest request) {
        // works the same as WebViewClient.shouldOverrideUrlLoading, 
        // but you have request.getAjaxData() which gives you the 
        // request body
   }
});
