尝试在 java 中使用 bing azure marketpalce 的搜索 api 我有这个代码：

import org.apache.commons.codec.binary.Base64;
import org.apache.http.client.ResponseHandler;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.BasicResponseHandler;
import org.apache.http.impl.client.DefaultHttpClient;

public class BingAPI2 {
    public static void main(String[] args) throws Exception{
        BingAPI2 b = null;
        b.getBing();

    }

public static void getBing() throws Exception {

        HttpClient httpclient = new DefaultHttpClient();

        try {
            String accountKey = "myAccountKey=";
            byte[] accountKeyBytes = Base64.encodeBase64((":" + accountKey).getBytes());
            String accountKeyEnc = new String(accountKeyBytes);

            HttpGet httpget = new HttpGet("https://api.datamarket.azure.com/Data.ashx/Bing/Search/Web?$Query=%27Datamarket%27&$format=json");
            httpget.setHeader("Authorization", "Basic <"+accountKeyEnc+">");

            System.out.println("executing request " + httpget.getURI());

            // Create a response handler
            ResponseHandler<String> responseHandler = new BasicResponseHandler();
            String responseBody = httpclient.execute(httpget, responseHandler);
            System.out.println("----------------------------------------");
            System.out.println(responseBody);
            System.out.println("----------------------------------------");

        } finally {
            // When HttpClient instance is no longer needed,
            // shut down the connection manager to ensure
            // immediate deallocation of all system resources
            httpclient.getConnectionManager().shutdown();
        }
    }

}

我得到一个错误：

线程“main”中的异常 org.apache.http.client.HttpResponseException：授权类型不支持您提供的。仅支持 Basic 和 OAuth

我首先看到的是你的台词

byte[] accountKeyBytes = Base64.encodeBase64((":" + accountKey).getBytes());

应该阅读：

byte[] accountKeyBytes = Base64.encodeBase64((accountKey + ":" + accountKey).getBytes());

还有你为此使用 apache 库的原因吗？我用于从 bing 获取 json 对象的代码使用 java.net，如下所示：

import java.net.URLConnection;
import java.net.URL;
import java.io.InputStreamReader;

class BingJson{

  JSONObject getJSONfromBing(String term){
  try{
    URLConnection c = new URL(term).openConnection();
    String key = (DatatypeConverter.printBase64Binary(("XXX" + ":" + "XXX").getBytes("UTF-8")));
    c.setRequestProperty("Authorization", String.format("Basic %s",key));
    c.connect();
    //etc.
  }
}

要构建 json 对象，我会说遵循以下代码： Convert InputStream to JSONObject
