Java企业微信服务商代开发获取AccessToken示例

这里主要针对的是企业微信服务商代开发模式 文档地址

可以看到里面大致有三种token，一个是服务商的token，一个是企业授权token，还有一个是应用的token
这里面主要有下面几个参数
首先是服务商的 corpid 和 provider_secret ，这个可以在 应用管理-通用开发参数 里面查看

然后是企业的 corpid 和企业的永久授权码 permanent_code ，这两个是需要在企业授权的的时候通过回调获取的，具体请参考官方文档 获取永久授权码

最后就是应用的 suite_id 和 suite_secret 还需要一个 suite_ticket ，前面两个在应用信息里面就可以看到，suite_ticket 这个也是需要通过回调获取 ，具体参考官方文档 推送suite_ticket

拿到这些参数后就好说了，剩下的都是调接口
直接上代码

这里面用到的 HttpsRequestUtil 工具类

import java.io.*;
import java.net.HttpURLConnection;
import java.net.URL;

/**

public class HttpsRequestUtil {

    public static String sendPostRequest(String urlString, String jsonInputString) throws IOException {
        URL url = new URL(urlString);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();

        // 设置请求方法为POST
        connection.setRequestMethod("POST");

        // 设置请求头
        connection.setRequestProperty("Content-Type", "application/json");
        connection.setRequestProperty("Accept", "application/json");

        // 启用输出流，用于发送请求数据
        connection.setDoOutput(true);

        try (OutputStream os = connection.getOutputStream()) {
            byte[] input = jsonInputString.getBytes("utf-8");
            os.write(input, 0, input.length);
        }

        // 获取响应
        try (BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream(), "utf-8"))) {
            StringBuilder response = new StringBuilder();
            String responseLine;
            while ((responseLine = br.readLine()) != null) {
                response.append(responseLine.trim());
            }
            return response.toString();
        } finally {
            // 关闭连接
            connection.disconnect();
        }
    }

    public static String sendGetRequest(String urlString) throws IOException {
        URL url = new URL(urlString);
        HttpURLConnection connection = (HttpURLConnection) url.openConnection();

        // 设置请求方法为GET
        connection.setRequestMethod("GET");

        // 设置请求头
        connection.setRequestProperty("Accept", "application/json");

        // 获取响应
        try (BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream(), "utf-8"))) {
            StringBuilder response = new StringBuilder();
            String responseLine;
            while ((responseLine = br.readLine()) != null) {
                response.append(responseLine.trim());
            }
            return response.toString();
        } finally {
            // 关闭连接

}

WeiXinProviderConst 就不贴了，里面就是记录上面那几个参数的

到这里可以发现，其实对接企业微信并不难，麻烦的地方就在于各种配置各种参数，然后就是回调，回调这个后面有空我也会整理出来
