javascript - 如何使用 webview 或 Web 浏览器在 android Studio 中显示 OKHTTP html 响应并与之交互

Question

我正在构建一个 Android 应用程序。我已经使用 OKHTTP 构建了一个请求，我得到的响应是一个由 html css 和 js 内容组成的字符串。此响应实际上是用户必须使用的一种形式，以允许应用程序与给定网站进行通信。

现在我希望用户能够看到该响应作为 html 页面并单击按钮以允许通信。唯一的问题是我不知道如何在 WebView 或网络浏览器中将该响应显示为 html。

来自 MainActivity:

                          Authenticate myAouth = new Authenticate("myCostumerKey","mySecretKey");
                           try {
                               myResponse=myAouth.run("myUrlHere");
                               //System.out.println( myResponse);
                           } catch (Exception e) {
                               e.printStackTrace();
                           }

认证类

public class Authenticate {
private final OkHttpClient client;
String[] myResponse =new String[2];
public Authenticate( final String consumerKey, final String consumerSecret) {

    client = new OkHttpClient.Builder()
            .authenticator(new Authenticator() {
                @Override public Request authenticate(Route route, Response response) throws IOException {
                    if (response.request().header("Authorization") != null) {
                        return null; // Give up, we've already attempted to authenticate.
                    }

                    System.out.println("Authenticating for response: " + response);
                    System.out.println("Challenges: " + response.challenges());
                    String credential = Credentials.basic(consumerKey, consumerSecret);
                    Request myRequest =response.request().newBuilder()
                            .header("Authorization", credential)
                            .build();
                    HttpUrl myURL = myRequest.url();
                    myResponse[0]= String.valueOf(myURL);
                    return myRequest;
                }
            })
            .build();
}

@RequiresApi(api = Build.VERSION_CODES.KITKAT)
public String[] run(String url) throws Exception {
    Request request = new Request.Builder()
            .url(url)
            .build();


    try (Response response = client.newCall(request).execute()) {
        if (!response.isSuccessful()) throw new IOException("Unexpected code " + response);
        myResponse[1]=response.body().string();
        System.out.println(" URL is "+myResponse[0]+" my response body is "+myResponse[1]);

    }

    return myResponse;
}}

您可以使用以下代码将String转换为HTML，然后将其显示在WebView中

    try {
        String html = new String(response, "UTF-8");
        String mime = "text/html";
        String encoding = "utf-8";

        myWebView.getSettings().setJavaScriptEnabled(true);
        myWebView.loadDataWithBaseURL(null, html, mime, encoding, null);
    } catch (UnsupportedEncodingException e) {
        e.printStackTrace();
    }
}
