使用HttpClient向服务器发送restful post请求

直接上代码：

public class RestClient {
    public static void main(String[] args) {
        String url = "http://ip地址/api/User/GetToken";
        HttpClient client = new HttpClient();
　　　　　//POST方法
        PostMethod method = new PostMethod(url);
　　　　　//传递参数
        NameValuePair[] data = {
                new NameValuePair("UserName", "sinopec\\xxxx"),
                new NameValuePair("Password", "xxxx") };
        method.setRequestBody(data);
        try {
            int statusCode = client.executeMethod(method);
            if (statusCode == 200) {
                String strJson = method.getResponseBodyAsString();
                System.out.println(strJson);
                // System.out.println(map.get("user").getUsername());
            }
        } catch (HttpException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
