目标主机不能为空，也不能在参数中设置。方案=null，主机=null，路径=eocribin.netne.net/FetchUserData.php

Question

收到错误，我不知道为什么我已经看了几个小时了，我觉得这是我遗漏的基本内容有人可以看看它可能是什么吗？

public class ServerRequests {
        ProgressDialog progressDialog;
        public static final int CONNECTION_TIMEOUT = 1000 * 15;
        public static final String SERVER_ADDRESS = "http://eocribin.netne.net";

我觉得我在上面的部分中标记了主机以供稍后用作变量，但它只将其注册为路径

    public ServerRequests(Context context) {
        progressDialog = new ProgressDialog(context);
        progressDialog.setCancelable(false);
        progressDialog.setTitle("Processing...");
        progressDialog.setMessage("Please wait...");
    }

    public void storeUserDataInBackground(User user,
                                          GetUserCallback userCallBack) {
        progressDialog.show();
        new StoreUserDataAsyncTask(user, userCallBack).execute();
    }

    public void fetchUserDataAsyncTask(User user, GetUserCallback userCallBack) {
        progressDialog.show();
        new fetchUserDataAsyncTask(user, userCallBack).execute();
    }

    /**
     * parameter sent to task upon execution progress published during
     * background computation result of the background computation
     */

    public class StoreUserDataAsyncTask extends AsyncTask<Void, Void, Void> {
        User user;
        GetUserCallback userCallBack;

        public StoreUserDataAsyncTask(User user, GetUserCallback userCallBack) {
            this.user = user;
            this.userCallBack = userCallBack;
        }

        @Override
        protected Void doInBackground(Void... params) {
            ArrayList<NameValuePair> dataToSend = new ArrayList<>();
            dataToSend.add(new BasicNameValuePair("name", user.name));
            dataToSend.add(new BasicNameValuePair("username", user.username));
            dataToSend.add(new BasicNameValuePair("password", user.password));
            dataToSend.add(new BasicNameValuePair("age", user.age + ""));

            HttpParams httpRequestParams = getHttpRequestParams();

            HttpClient client = new DefaultHttpClient(httpRequestParams);
            HttpPost post = new HttpPost(SERVER_ADDRESS
                    + "/Register.php");

            try {
                post.setEntity(new UrlEncodedFormEntity(dataToSend));
                client.execute(post);
            } catch (Exception e) {
                e.printStackTrace();
            }

            return null;
        }

您在 path=eocribin.netne.net/FetchUserData.php

中缺少 "http://"
