场景：用户上传身份证照片后，把照片保存再云存储，然后通过cloud.getTempFileURL换出这个照片的临时url，把这个url通过云函数传递给腾讯云接口并且得到返回的结果。 已知：通过腾讯云的 API Explorer 得到node环境中请求的代码（附上API Explorer链接：https://console.cloud.tencent.com/api/explorer?Product=ocr&Version=2018-11-19&Action=IDCardOCR&SignVersion= 代码如下：（腾讯云ID和密钥，以及图片url没有写入，替换进去即可）（我已经再node环境中使用过以下代码可以得到满意的结果） 问题：如何把这个代码迁移到微信云函数里去？？ const tencentcloud = require("../../../../tencentcloud-sdk-nodejs"); const OcrClient = tencentcloud.ocr.v20181119.Client; const models = tencentcloud.ocr.v20181119.Models; const Credential = tencentcloud.common.Credential; const ClientProfile = tencentcloud.common.ClientProfile; const HttpProfile = tencentcloud.common.HttpProfile; let cred = new Credential("腾讯云ID", "腾讯云密钥"); let httpProfile = new HttpProfile(); httpProfile.endpoint = "ocr.tencentcloudapi.com"; let clientProfile = new ClientProfile(); clientProfile.httpProfile = httpProfile; let client = new OcrClient(cred, "ap-guangzhou", clientProfile); let req = new models.IDCardOCRRequest(); let params = '{"ImageUrl":"这里写入图片URL连接","CardSide":"FRONT"}' req.from_json_string(params); client.IDCardOCR(req, function(errMsg, response) { if (errMsg) { console.log(errMsg); return; } console.log(response.to_json_string()); }); 云函数 // 云函数入口文件 const cloud = require('wx-server-sdk') cloud.init() // exports.main = async (event, context) => { }

在开发者工具中使用cloud.openapi.subscribeMessage.send后怎么看到最后的服务通知弹出（如下图），我在真机调试里也没看到，还是我写的有问题 [图片]
