无法连接到Android Studio上的本地API

Question

所以我正在开发一个Android应用程序，它必须与我编码的API进行交互。目前我只是在本地运行API。我已经测试了所有的路线，它们都可以工作。

现在我想在我的Android应用程序上向这个API发送请求。为此，我使用一个类Request estManager，它扩展了AsyncWG来管理每个请求（如果你问的话，我可以给你看代码）。我已经添加了

当我使用电脑的IP地址通过RequestManager执行请求时，它会暂停一段时间，然后抛出SocketTimeoutException，并出现以下错误：无法连接到/XX。XX。XX。XX（端口XXXX）来自/XX。XX。XX。XX（端口XXXX）。请注意，从邮递员处发出相同的请求是没有问题的。

所以我尝试了多种方法，比如添加一个文件network_security_config.xml来允许带有我电脑的IP地址的流量，我停用了我的防火墙，我在防火墙上添加了几个入站和出站规则来授予Android Studio的权限，IP地址，使用的端口等...

有人经历过同样的情况吗，或者有人能帮我解决这个问题吗？我真的需要让它工作...

编辑：以下是RequestManager类：

class RequestManager extends AsyncTask<HashMap<String, Object>, Void, Response> {

    protected Response doInBackground(HashMap<String, Object>... parameterMaps) {
        Response response = null;
        HashMap<String, Object> params = parameterMaps[0];
        String method = (String) params.get("method");
        if ("GET".equals(method)) {
            response = doGet(params);
        } else if ("POST".equals(method)) {
            response = doPost(params);
        } else if ("UPDATE".equals(method)) {
            response = doUpdate(params);
        } else if ("DELETE".equals(method)) {
            response = doDelete(params);
        }
        return response;
    }

    private Response doGet(HashMap<String, Object> params) {
        Response response = null;
        try {
            OkHttpClient client = new OkHttpClient();

            Context context = (Context) params.get("context");
            String protocol = Config.getConfigValue(context, "protocol");
            String ipAddress = Config.getConfigValue(context, "ipAddress");
            String port = Config.getConfigValue(context, "port");
            String route = (String) params.get("route");
            String url = protocol + ipAddress + ":" + port + "/" + route;

            Request request = new Request.Builder()
                    .url(url)
                    .get()
                    .addHeader("Content-Type", "application/json")
                    .addHeader("Cache-Control", "no-cache")
                    .build();

            response = client.newCall(request).execute();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return response;
    }

    private Response doPost(HashMap<String, Object> params) {
        Response response = null;
        try {
            OkHttpClient client = new OkHttpClient();

            Context context = (Context) params.get("context");
            String protocol = Config.getConfigValue(context, "protocol");
            String ipAddress = Config.getConfigValue(context, "ipAddress");
            String port = Config.getConfigValue(context, "port");
            String route = (String) params.get("route");
            String url = protocol + ipAddress + ":" + port + "/" + route;

            MediaType mediaType = MediaType.parse("application/json");
            String bodyContent = params.get("body").toString();
            RequestBody body = RequestBody.create(mediaType, bodyContent);

            Request request = new Request.Builder()
                    .url(url)
                    .post(body)
                    .addHeader("Content-Type", "application/json")
                    .addHeader("Cache-Control", "no-cache")
                    .build();

            response = client.newCall(request).execute();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return response;
    }

    private Response doUpdate(HashMap<String, Object> params) {
        Response response = null;
        try {
            OkHttpClient client = new OkHttpClient();

            Context context = (Context) params.get("context");
            String protocol = Config.getConfigValue(context, "protocol");
            String ipAddress = Config.getConfigValue(context, "ipAddress");
            String port = Config.getConfigValue(context, "port");
            String route = (String) params.get("route");
            String url = protocol + ipAddress + ":" + port + "/" + route;

            MediaType mediaType = MediaType.parse("application/json");
            String bodyContent = params.get("body").toString();
            RequestBody body = RequestBody.create(mediaType, bodyContent);

            Request request = new Request.Builder()
                    .url(url)
                    .put(body)
                    .addHeader("Content-Type", "application/json")
                    .addHeader("Cache-Control", "no-cache")
                    .build();

            response = client.newCall(request).execute();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return response;
    }

    private Response doDelete(HashMap<String, Object> params) {
        Response response = null;
        try {
            OkHttpClient client = new OkHttpClient();

            Context context = (Context) params.get("context");
            String protocol = Config.getConfigValue(context, "protocol");
            String ipAddress = Config.getConfigValue(context, "ipAddress");
            String port = Config.getConfigValue(context, "port");
            String route = (String) params.get("route");
            String url = protocol + ipAddress + ":" + port + "/" + route;

            Request request = new Request.Builder()
                    .url(url)
                    .delete()
                    .addHeader("Content-Type", "application/json")
                    .addHeader("Cache-Control", "no-cache")
                    .build();

            response = client.newCall(request).execute();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return response;
    }

    protected void onPostExecute(Response response) {

    }
}

我这样称呼它：

        HashMap<String, Object> params = new HashMap<>();
        JSONObject body = Utils.jsonify(content);
        params.put("body", body);
        params.put("route", Constants.User.BASE_USER);
        params.put("context", SignUp.this);
        params.put("method", "POST");

AsyncTask<HashMap<String, Object>, Void, Response> requestManager = new RequestManager().execute(params);

使用localtunnel临时公开本地api。这就像一个魅力，非常容易使用。已将其用于多个项目，以针对本地API进行测试。
