微信开放平台_第三方平台授权流程_接口调用令牌

六、接口调用令牌

6.1 官网说明

在公众号/小程序接口调用令牌（authorizer_access_token）失效时，可以使用刷新令牌（authorizer_refresh_token）获取新的接口调用令牌。

注意： authorizer_access_token 有效期为 2 小时，开发者需要缓存 authorizer_access_token，避免获取/刷新接口调用令牌的 API 调用触发每日限额。缓存方法可以参考：https://developers.weixin.qq.com/doc/offiaccount/Basic_Information/Get_access_token.html

请求地址

POST https://api.weixin.qq.com/cgi-bin/component/api_authorizer_token?component_access_token=COMPONENT_ACCESS_TOKEN

请求参数说明

POST 数据示例：

{
  "component_appid": "appid_value",
  "authorizer_appid": "auth_appid_value",
  "authorizer_refresh_token": "refresh_token_value"
}

6.2 获取流程及示意代码

    /**
	 * 获取接口调用令牌
	 * @param authorizerAppid	授权方 appid
	 * @param authorizerRefreshToken	授权方 刷新令牌
	 * @return
	 */
	public static String getAuthorizerAccessToken(String authorizerAppid,String authorizerRefreshToken){
		webChatCatchUtil = SpringContextHolder.getBean("webChatCatchUtil");
		String authorizerAccessToken = webChatCatchUtil.getWeixinOpenAuthorizerAccessToken();
		if(authorizerAccessToken==null) {
			authorizerAccessToken = OpAuthCodeUtil.getAuthorizerAccessTokenInstant(authorizerAppid,authorizerRefreshToken);
		}
		return authorizerAccessToken;
	}

	private static String getAuthorizerAccessTokenInstant(String authorizerAppid,String authorizerRefreshToken){
		webChatCatchUtil = SpringContextHolder.getBean("webChatCatchUtil");
		String componentAccessToken = getOpenAccToken();   //令牌
		//设置请求参数
		JSONObject json = new JSONObject();
		json.put("component_appid", ComponentConfig.APPID);
		json.put("authorizer_appid", authorizerAppid);
		json.put("authorizer_refresh_token", authorizerRefreshToken);
		String API_COMPONENT_TOKEN_URl = WeixinImSetting.OPEN_URL_AUTHORIZERTOKEN;

		String responseData = HttpSend.httpPost(API_COMPONENT_TOKEN_URl + componentAccessToken, json.toString(), null);
		JSONObject postData = JSONObject.fromObject(responseData);
		log.info("====================返回post结果：" + postData);
		String authorizerAccessToken = (String) postData.get("authorizer_access_token");
		Integer expires_in = (Integer) postData.get("expires_in");     //有效期，单位：秒
		log.info("getAuthorizerAccessTokenInstant-result:"+json);
		webChatCatchUtil.setWeixinOpenPreAuthCode(authorizerAccessToken,expires_in);
		return authorizerAccessToken;
	}

结果参数说明

返回结果示例：

{
  "authorizer_access_token": "some-access-token",
  "expires_in": 7200,
  "authorizer_refresh_token": "refresh_token_value"
}
