我正在尝试将curl命令转换为Java(使用Apache HttpClient 4.x)：

export APPLICATION_ID=SOME_ID

export REST_API_KEY=SOME_KEY

curl -i -X POST \n -H "X-Parse-Application-Id: ${APPLICATION_ID}" \n -H "X-Parse-REST-API-Key: ${REST_API_KEY}" \n -H "Content-Type: image/png" \n --data-binary @/Users/thomas/Desktop/greep-small.png \n https://api.parse.com/1/files/greep.png

但出现以下错误：{“错误”：“未经授权”}.

这是我的Java代码如下所示：

DefaultHttpClient httpclient = new DefaultHttpClient();

HttpHost targetHost = new HttpHost("localhost", 80, "http");

httpclient.getCredentialsProvider().setCredentials(

new AuthScope(targetHost.getHostName(), targetHost.getPort()),

new UsernamePasswordCredentials("username", "password"));

HttpPost httpPost = new HttpPost("https://api.parse.com/1/files/greep.png");

System.out.println("executing request:

" + httpPost.getRequestLine());

List nameValuePairs = new ArrayList(2);

nameValuePairs.add(new BasicNameValuePair("Example-Application-Id", "SOME_ID"));

nameValuePairs.add(new BasicNameValuePair("Example-REST-API-Key", "SOME_KEY"));

nameValuePairs.add(new BasicNameValuePair("Content-Type", "image/png"));

httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

HttpResponse response = httpclient.execute(httpPost);

HttpEntity responseEntity = response.getEntity();

System.out.println("----------------------------------------");

System.out.println(response.getStatusLine());

if (responseEntity != null) {

System.out.println("Response content length: "

+ responseEntity.getContentLength());

}

System.out.println(EntityUtils.toString(responseEntity));

httpclient.getConnectionManager().shutdown();

如何转换以-H开头的卷曲线和以“ –data-binary”开头的卷曲线？ -d的java等效项是什么？

-d '{ "name":"Andrew", "picture": { "name": "greep.png", "__type": "File" } }' \n

任何提示表示赞赏.谢谢
