我试图连接到的Grooveshark API,这是HTTP请求
POST URL
http://api.grooveshark.com/ws3.php?sig=f699614eba23b4b528cb830305a9fc77
POST payload
{"method":'addUserFavoriteSong",'parameters":{"songID":30547543},"header":
{"wsKey":'key","sessionID":'df8fec35811a6b240808563d9f72fa2'}}
我的问题是我怎么能发送通过Java这个要求吗?
基本上,你可以使用标准的Java API做到这一点。 退房URL
, URLConnection
,也许HttpURLConnection
。 他们在包java.net
。
至于具体的API签名,尝试sStringToHMACMD5
发现在这里。
请记住要更改您的API密钥,这是非常重要的,因为每个人都知道它知道。
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();
你可以看看到Commons的HttpClient包。
这是相当简单的创建POST
的,具体你可以复制在这里找到的代码: http://hc.apache.org/httpclient-3.x/methods/post.html :
PostMethod post = new PostMethod( "http://api.grooveshark.com/ws3.php?sig=f699614eba23b4b528cb830305a9fc77" );
NameValuePair[] data = {
new NameValuePair( "method", "addUserFavoriteSong..." ),
...
};
post.setRequestBody(data);
InputStream in = post.getResponseBodyAsStream();
...
干杯,
