libgdx的http请求方法不适用于Web应用程序

Question

I'm testing the net class of libgdx library to get a json from the page passed to the setUrl method. This portion of code comes from a class called ApplicationScreen that implements the libgdx Screen interface. That's the code:

@Override
public void show() {

    String requestContent = null;

    httpRequest = new HttpRequest(Net.HttpMethods.GET);
    httpRequest.setUrl("http://localhost/projects/SqlParser/index.php");
    httpRequest.setHeader("Content-Type", "text/plain");
    httpRequest.setContent(requestContent);

    Gdx.net.sendHttpRequest(httpRequest, new HttpResponseListener() {

        public void handleHttpResponse(HttpResponse httpResponse) {

            final int statusCode = httpResponse.getStatus().getStatusCode();

            System.out.println("HTTP Request status: " + statusCode);
            System.out.println("Content:");
            System.out.println(httpResponse.getResultAsString());


        }

        public void failed(Throwable t) {
            System.out.println("HTTP request failed!");
        }

    });

}

When I run the desktop version I get this message on the Console window "HTTP Request Status: 200", followed by the content of the http request, so the code does what I expect it should do. When I run instead the html version I get this message on the Console "HTTP Request status: 0". Any suggestion?

Did you set up the permissions in the android manifest?

How to add manifest permission to android application?

Also need to check that you use the ip of the computer you are using when passing the the url rather than localhost.

Hope this is of some help...even if it is long overdue.

这可能为时已晚，但就我而言，事实证明这是违反同源政策的行为。

我使用不安全版本的Google Chrome解决了这个问题，使用以下选项启动浏览器： - allow-file-access-from-files --disable-web-security
