我使用Sentiment-140提供的公共API来查找小文本是正面,负面还是中性。虽然我可以成功地使用他们简单的HTTP-JSON服务,但我没有使用CURL。这是我的代码:在JAVA中接收来自CURL的响应
public static void makeCURL(String jsonData) throws MalformedURLException, ProtocolException, IOException {
byte[] queryData = jsonData.getBytes("UTF-8");
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("10.1.1.1", 8080));
HttpURLConnection con = (HttpURLConnection) new URL("http://www.sentiment140.com/api/bulkClassifyJson").openConnection(proxy);
con.setRequestMethod("POST");
con.setDoOutput(true);
OutputStream os = con.getOutputStream();
InputStream instr = con.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(instr));
os.write(queryData);
os.close();
String lin;
while((lin = br.readLine())!=null){
System.out.println("[Debug]"+lin); // I expect some response here But it's not showing anything
}
}
我在做什么错?
您的代理是否需要验证?有什么异常?堆栈跟踪 ? – 2013-03-20 06:03:24
没有身份验证。我可以成功地使用类似的技术来获得常规的HTTP响应... – Aditya 2013-03-20 06:31:57
尝试移动这些行:InputStream instr = con.getInputStream(); BufferedReader br = new BufferedReader(new InputStreamReader(instr));在os.write()和os.close()之后。 – Kylar 2013-03-20 16:09:12
