Java Android WebView未重定向到其他页面。水疗网站

我有一个网站，我希望该网站成为一个移动应用程序，因为它是响应。我决定将其作为一个WebView，因为它更容易实现，因为我不是一个移动开发人员。我的网站使用Laravel+Vuejs SPA（单页应用程序）。但当我点击导航栏登录后，它不会将我重定向到下一页。有人能告诉我我错过了什么吗？这与我的网站有关还是仅仅是安卓系统的问题

MainActivity.java

package com.example.carrental;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends AppCompatActivity {

    WebView web;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        web = findViewById(R.id.webView);
        WebSettings webSettings = web.getSettings();
        webSettings.setJavaScriptEnabled(true);
        web.setWebViewClient(new Callback());
        web.loadUrl("http://52.74.70.6:90/");

    }

    private class Callback extends WebViewClient {
        @Override
        public boolean shouldOverrideKeyEvent(WebView view, KeyEvent event) {
            return false;
        }
    }
}

当网站在web视图中打开时，您可以通过以下代码查看url重定向

 public class PaymentWebActivity extends Activity {

    private WebView webView;
    private String link = "";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        webView = (WebView) findViewById(R.id.webview);
        if (getIntent().getExtras() != null) {
            link = getIntent().getExtras().getString("link");
        }
        initWebView();
    }

    private void initWebView() {
        WebSettings webSettings = webView.getSettings();
        webSettings.setJavaScriptEnabled(true);
        WebViewClientImpl webViewClient = new WebViewClientImpl(this);
        webView.setWebViewClient(webViewClient);
        webView.loadUrl(link);
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if ((keyCode == KeyEvent.KEYCODE_BACK) && this.webView.canGoBack()) {
            this.webView.goBack();
            return true;
        }

        return super.onKeyDown(keyCode, event);
    }

            finish();
        } else if (checkErrorUrl(url)) {
            webView.destroy();
            Uri uri = Uri.parse(url);
            String errorMessage = uri.getQueryParameter("message");
            showConfirmDialog(errorMessage);
        }

        dialog.setCancelable(false);
        dialog.show();
    }

    private boolean checkSuccessUrl(String url) {
        return url.contains("success.php");
    }

    private boolean checkErrorUrl(String url) {

    }
}

• success.php
• error.php

这两个文件是在服务器端创建的，因此当checkUrl找到这些文件时，我们可以根据url执行逻辑。您也可以根据找到的内容转发页面。

好的，您可以解释更多内容吗？如何使用代码？sirsee在我的帖子中，我给了你整个页面的代码，但是从服务器端你需要创建你想要转发给用户的文件。我在我的代码中提到了两个文件（success.php和error.php），因此这些文件由override url加载方法监视，因此一旦找到特定文件，您就可以确定需要转发的文件，但我使用的是框架。如果我只在那里设置一个路径，比如

localhost/success

，可以吗？您使用了哪个框架？
