企业微信第三方应用（四）基于springboot开发（获取provider_access_token,suite_access_token,access_token）

前言
上一篇“企业微信第三方应用（三）基于springboot开发（获取Ticket，auth_code）”我们讲到了如何获取suite_ticket和auth_code两个重要参数。

下面将讲解如何获取企业微信第三方应用的三种token方式

获取TOKEN

上面图是获取三种token所需要的参数

1、获取服务商凭证provider_access_token

WeChatThirdTokenController:

package com.wechat.controller;

import com.wechat.service.IWeChatThirdTokenService;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * 第三方应用操作
 *
 * @author: wx
 * @date: 2022/4/1
 */
@Slf4j
@RestController
@RequestMapping(value = "wechatToken")
public class WeChatThirdTokenController {

    @Autowired
    private IWeChatThirdTokenService weChatThirdTokenService;


    /**
     * 获取第三方应用凭证
     */
    @ApiOperation(value = "获取第三方应用凭证")
    @PostMapping(value = "getSuiteToken")
    public void getSuiteToken(){
        //获取第三方应用凭证
        weChatThirdTokenService.getSuiteToken();
    }

    /**
     * 服务商的token
     */
    @ApiOperation(value = "服务商的token")
    @PostMapping(value = "getProviderToken")
    public void getProviderToken(){
        //服务商的token
        weChatThirdTokenService.getProviderToken();
    }

    /**
     * 获取企业凭证
     */
    @ApiOperation(value = "获取企业凭证")
    @PostMapping(value = "getCorpToken")
    public void getCorpToken(){
        weChatThirdTokenService.getCorpToken();
    }
}

IWeChatThirdTokenService:

package com.wechat.service;

/**
 * 获取token
 */
public interface IWeChatThirdTokenService {

    /**
     * 获取第三方应用凭证
     */
    void getSuiteToken();

    /**
     * 服务商的token
     */
    void getProviderToken();

    /**
     * 获取企业凭证
     */
    void getCorpToken();
}

接口实现类WeChatThirdTokenServiceImpl:
