我正在尝试连接到groovehark API，这是http请求

I'm trying to connect to the grooveshark API, this is the http request

POST URL
http://api.grooveshark.com/ws3.php?sig=f699614eba23b4b528cb830305a9fc77

{"method":'addUserFavoriteSong",'parameters":{"songID":30547543},"header": 
{"wsKey":'key","sessionID":'df8fec35811a6b240808563d9f72fa2'}}

我的问题是如何通过Java发送此请求？

My question is how can I send this request via Java?

推荐答案

基本上，您可以使用标准Java API来完成查看 URL ， URLConnection ，也许 HttpURLConnection 。它们在包 java.net 。

Basically, you can do it with the standard Java API. Check out URL, URLConnection, and maybe HttpURLConnection. They are in package java.net.

关于API特定签名，请尝试在 sStringToHMACMD5 。 com / questions / 8396297 / android-how-to-create-hmac-md5-string>这里。

As to the API specific signature, try sStringToHMACMD5 found in here.

并记得改变你的API KEY，这是非常重要的，因为每个人都知道它。

String payload = "{\"method\": \"addUserFavoriteSong\", ....}";
String key = ""; // Your api key.
String sig = sStringToHMACMD5(payload, key);

URL url = new URL("http://api.grooveshark.com/ws3.php?sig=" + sig);
URLConnection connection = url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);

connection.connect();

OutputStream os = connection.getOutputStream();
PrintWriter pw = new PrintWriter(new OutputStreamWriter(os));
pw.write(payload);
pw.close();

InputStream is = connection.getInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
String line = null;
StringBuffer sb = new StringBuffer();
while ((line = reader.readLine()) != null) {
    sb.append(line);
}
is.close();
String response = sb.toString();
