1 修改index.vue

此程式碼可以上傳檔案
進入C:\htmlstudy\weixin\todos\src\components下的檔案

2 修改todos下的cloudbaserc.json程式碼

          "functions": [
            {
              "name": "gettodo",
              "timeout": 5,
              "envVariables": {},
              "runtime": "Nodejs10.15",
              "memory": 128,
              "aclRule": {
                "invoke": true
              }
            },
            {
              "name": "deltodo",
              "timeout": 5,

              }

            {
              "name": "addtodo",
              "timeout": 5,
              "envVariables": {},
              "runtime": "Nodejs10.15",

              }

          ]
        }
      },
      "auth": {

            }
          ]
        }
      }
    }
  },
  "functions": [],
  "region": "ap-shanghai"
}

3 在cloudfunctions目錄下新建puttodo目錄

4 copy addtodo中的3個檔案、一個資料夾到puttodo目錄

5 修改 puttodo中index.js

const cloud = require('./clouddb')

async function puttodo(event) {
  var req=event;
  if(req._id==undefined){
    return;
}

const backdata=await cloud.collection('todo').doc(req._id).update({fileId:req.fileId})
return backdata
}

exports.main = async (event, context) => {
  return puttodo(event);
};

6 部署

tcb
或
tcb fn code update puttodo
