java - Bing Autosuggest api for an android app，但它给出的响应代码为 404 并且找不到资源，但相同的代码在 java 编译器中工作正常

Question

我想在 android 应用程序中使用 Bing Autosuggest API。我使用了此处记录的代码：- https://docs.microsoft.com/en-us/azure/cognitive-services/Bing-Autosuggest/quickstarts/java 在运行/编译相同的代码时代码工作正常简单的java编译器：- https://www.onlinegdb.com/online_java_compiler

我的应用程序能够在网络视图中打开网址https://api.cognitive.microsoft.com/bing/v7.0/Suggestions/?subscription-Key=my_key&q=india （这意味着在应用程序）。Android 需要在一个单独的线程中调用它，这就是我在这里使用 Async 的原因。

对于下面的代码，第一个 URL 工作正常（响应代码为 200），但第二个给出的响应代码为 404。

两者都可以在浏览器中使用其确切的 url 链接打开

    url = new URL("https://api.bing.com/osjson.aspx?query=abcd");
    url = new URL("https://api.cognitive.microsoft.com/bing/v7.0/Suggestions/?mkt=en-IN&subscription-Key=key&q=india");

    HttpsURLConnection connection = null;
    connection = (HttpsURLConnection) url.openConnection();
    connection.setRequestMethod("GET");
    connection.setDoOutput(true);
    int HttpsREsult = connection.getResponseCode(); 

如文档中所述，我编写的代码如下：-

在Android中，代码编写如下：-

 public class bing_ac_main extends AsyncTask<String,Void,String> {
    protected String subscriptionKey = "my key";  
    protected String host = "https://api.cognitive.microsoft.com";
    protected String path = "/bing/v7.0/Suggestions";
    protected String mkt = "en-IN";
    protected String query = "sail";
    @Override
    protected String doInBackground(String... strings) {
        String encoded_query = null;
        try {
            encoded_query = URLEncoder.encode (query, "UTF-8");
            String params = "?mkt=" + mkt + "&q=" + encoded_query;

            URL url = new URL (host + path + params);
            HttpsURLConnection connection = null;
            connection = (HttpsURLConnection) url.openConnection();
            connection.setRequestMethod("GET");
            connection.setRequestProperty("Ocp-Apim-Subscription-Key", subscriptionKey);
            connection.setDoOutput(true);
            int HttpsREsult = connection.getResponseCode();
            String Httpsstring= connection.getResponseMessage();
      .......

在在线编译器中，我在函数中编写了相同的代码：-

    public  static String getResponse(){

        String subscriptionKey = "my key";  
        String host = "https://api.cognitive.microsoft.com";
        String path = "/bing/v7.0/Suggestions";
        String mkt = "en-IN";
        String query = "ind";

        String encoded_query = null;
        try {
            encoded_query = URLEncoder.encode (query, "UTF-8");
            String params = "?mkt=" + mkt + "&q=" + encoded_query;

            URL url = new URL (host + path + params);
            HttpsURLConnection connection = null;
            connection = (HttpsURLConnection) url.openConnection();
            connection.setRequestMethod("GET");

            connection.setRequestProperty("Ocp-Apim-Subscription-Key", subscriptionKey);

            connection.setDoOutput(true);
            int HttpsREsult = connection.getResponseCode();
     .....
}

我预计 HttpsResult 应该是 200，但在 android 中实际输出是 404。我在相同代码的在线编译器中将 HttpsResult 设为 200，这是正确的
