// app.js App({ onLaunch() { if (!wx.cloud) { console.error('请使用 2.2.3 或以上的基础库以使用云能力'); } else { wx.cloud.init({ env: 'your-env-id' // 这里填写你在FinClip创建的环境ID }); } } });
imageRecognition
的云函数,并编写图像识别逻辑。// cloudfunctions/imageRecognition/index.js const cloud = require('wx-server-sdk'); const tencentcloud = require('tencentcloud-sdk-nodejs'); cloud.init(); const CVM = tencentcloud.cvm.v20170312.Client; const clientConfig = { credential: { secretId: "YOUR_SECRET_ID", secretKey: "YOUR_SECRET_KEY", }, region: "ap-shanghai", profile: { httpProfile: { endpoint: "cvm.tencentcloudapi.com", }, }, }; const client = new CVM(clientConfig); exports.main = async (event, context) => { const { fileID } = event; const res = await cloud.downloadFile({ fileID, }); const buffer = res.fileContent; // 调用图像识别接口 const params = { Image: buffer.toString('base64'), }; return client.ImageRecognition(params).then( (data) => { return { success: true, data, }; }, (err) => { console.error("error", err); return { success: false, error: err, }; } ); };
