写一个post请求，有以下要求： 请求地址 URL：http://172.16.10.13:18080/api/sso/getUserInfo post请求，Body格式：form-data header中的key有这些参数：timestamp，appKey，sign，，version body有这些参数：authCode，account，nickName，name 这个请求的返回示例为{ "success": true, "code": 200, "message": "请求成功", "data": { "account": "50011737", "nickName": "张三", "name": "张三" } } 将account解析出来，用Java代码写

好的，以下是使用Java代码发送post请求并解析返回数据中的account字段的示例代码：

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.HashMap;
import java.util.Map;

public class Main {
    public static void main(String[] args) {
        String url = "http://172.16.10.13:18080/api/sso/getUserInfo";
        Map<String, String> headers = new HashMap<>();
        headers.put("timestamp", "your_timestamp");
        headers.put("appKey", "your_appKey");
        headers.put("sign", "your_sign");
        headers.put("version", "your_version");
        
        Map<String, String> body = new HashMap<>();
        body.put("authCode", "your_authCode");
        body.put("account", "your_account");
        body.put("nickName", "your_nickName");
        body.put("name", "your_name");

        try {
            String response = sendPostRequest(url, headers, body);
            String account = parseAccountFromResponse(response);
            System.out.println("Account: " + account);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    private static String sendPostRequest(String url, Map<String, String> headers, Map<String, String> body) throws IOException {
        URL obj = new URL(url);
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();
        con.setRequestMethod("POST");
        
        // Set request headers
        for (Map.Entry<String, String> entry : headers.entrySet()) {
            con.setRequestProperty(entry.getKey(), entry.getValue());
        }

        StringBuilder postData = new StringBuilder();
        // Set request body
        for (Map.Entry<String, String> entry : body.entrySet()) {
            if (postData.length() != 0) {
                postData.append("&");
            }
            postData.append(entry.getKey()).append("=").append(entry.getValue());
        }
        byte[] postDataBytes = postData.toString().getBytes("UTF-8");
        
        con.setDoOutput(true);
        con.getOutputStream().write(postDataBytes);

        BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
        String inputLine;
        StringBuilder response = new StringBuilder();
        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

        return response.toString();
    }

    private static String parseAccountFromResponse(String response) {
        // Parse the account field from the response JSON
        // Here is a simple example assuming the response is always in the same format as the provided example
        int startIndex = response.indexOf("\"account\": \"") + "\"account\": \"".length();
        int endIndex = response.indexOf("\"", startIndex);
        return response.substring(startIndex, endIndex);
    }
}

请将代码中的 `your_` 替换为实际的值，并根据实际情况调整解析返回数据中account字段的方法`parseAccountFromResponse`，以适应实际返回数据的格式。
