如何在Android中使用Microsoft Translator API

用于Android示例的Microsoft Translator API自2017年3月起已被弃用（仅此一年）。 所以我很难在android上翻译文本。 任何人都可以帮我在android上做这个工作吗？ 只是我已经在java中使用它，但我无法在Android上运行它。 我已经尝试过使用asynctask，但无济于事，没有翻译出来。 或者我刚刚做了一个错误的asyc任务？

应用程序的界面是这样的：

---

它只有一个简单的文本字段，其翻译应该在另一个文本字段中输出。 翻译是从韩语到英语。

Android代码是这样的。

import android.os.AsyncTask; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.view.View; import android.widget.TextView; import org.apache.commons.io.IOUtils; import java.net.URL; import java.net.URLEncoder; import java.util.regex.Matcher; import java.util.regex.Pattern; import javax.net.ssl.HttpsURLConnection; public class MainActivity extends AppCompatActivity { //MS Translator Key is in here public static String key = ""; private TextView txtTranslatedText, txtOriginalText; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); txtOriginalText = findViewById(R.id.txtOriginalText); txtTranslatedText = findViewById(R.id.txtTranslatedText); } public void translate(View view) { // String textOrig = txtOriginalText.getText().toString(); // String textOrig ="안녕하세요 123 -)^ 친구"; String textOrig; textOrig=txtOriginalText.getText().toString(); String output; output=getTranslation(textOrig); txtTranslatedText.setText(output); } public static String getTranslation(String translatedTextStr) { try { // Get the access token // The key got from Azure portal, please see https://docs.microsoft.com/en-us/azure/cognitive-services/cognitive-services-apis-create-account String authenticationUrl = "https://api.cognitive.microsoft.com/sts/v1.0/issueToken"; HttpsURLConnection authConn = (HttpsURLConnection) new URL(authenticationUrl).openConnection(); authConn.setRequestMethod("POST"); authConn.setDoOutput(true); authConn.setRequestProperty("Ocp-Apim-Subscription-Key", key); IOUtils.write("", authConn.getOutputStream(), "UTF-8"); String token = IOUtils.toString(authConn.getInputStream(), "UTF-8"); // System.out.println(token); //Code to Display Token // Using the access token to build the appid for the request url String appId = URLEncoder.encode("Bearer " + token, "UTF-8"); String text = URLEncoder.encode(translatedTextStr, "UTF-8"); String from = "ko"; String to = "en"; String translatorTextApiUrl = String.format("https://api.microsofttranslator.com/v2/http.svc/GetTranslations?appid=%s&text=%s&from=%s&to=%s&maxTranslations=5", appId, text, from, to); HttpsURLConnection translateConn = (HttpsURLConnection) new URL(translatorTextApiUrl).openConnection(); translateConn.setRequestMethod("POST"); translateConn.setRequestProperty("Accept", "application/xml"); translateConn.setRequestProperty("Content-Type", "text/xml"); translateConn.setDoOutput(true); String TranslationOptions = "" + "general" + "text/plain" + "True" + "" + "contact with each other" + ""; translateConn.setRequestProperty("TranslationOptions", TranslationOptions); IOUtils.write("", translateConn.getOutputStream(), "UTF-8"); String resp = IOUtils.toString(translateConn.getInputStream(), "UTF-8"); // System.out.println(resp+"\n\n"); String s=resp; Pattern assign_op=Pattern.compile("()" + "|()" + "|[()\\\\[\\\\]{};=#.,'\\\\^:@!$%&_`*-]" + "|[a-zA-Z0-9\\s]*" + ""); Matcher m = assign_op.matcher(s) ; String actualTranslation=""; Boolean endOfTransTxt=false,startOfTransTxt=false,concat=false; String foundRegexStr="",tempStr=""; while (m.find()) { foundRegexStr=m.group(); if(m.group().matches("()")) { startOfTransTxt=true; } else if(m.group().matches("()")) { endOfTransTxt=true; concat=false; } else{ startOfTransTxt=false; endOfTransTxt=false; } if(startOfTransTxt==true) { concat=true; } else if(concat==true) { tempStr=tempStr+""+m.group(); } else { } } // System.out.println("\nTranslated Text: "+tempStr); translatedTextStr=tempStr; } catch (Exception e) { e.printStackTrace(); } return translatedTextStr; } }

我认为你做错了AsyncTask 。 你可以这样做：

 private class TransAsynTask extends AsyncTask{ @Override protected String doInBackground(String... strings) { String output = getTranslation(strings[0]); return output; } @Override protected void onPostExecute(String s) { txtTranslatedText.setText("Output: " + s); super.onPostExecute(s); } } 

在onCreate你打电话：

  String textOrig; textOrig = txtOriginalText.getText().toString(); new TransAsynTask().execute(textOrig); /*String output; output = getTranslation(textOrig); txtTranslatedText.setText("Translated Text: " + output);*/
