Firebase函数不记录“console.log()”语句

get() 方法,参见文档 here 这表示“要在异步操作后返回数据,请返回一个promise。promise返回的数据将发送回客户端。”

exports.purchaseItem = functions.https.onCall((data, context) => {
  console.log('data:')
  console.log(data)
  let lbcCustomerStripeToken = data.lbcCustomerStripeToken
  let lbcStoreId = data.lbcStoreId
  let amount = data.amount
  console.log('lbcCustomerStripeToken:')
  console.log(lbcCustomerStripeToken)
  console.log('lbcStoreId:')
  console.log(lbcStoreId)
  console.log('amount:')
  console.log(amount)

  let lbcFee = Math.round(amount * 0.02)

  return db.collection('stores').doc(lbcStoreId).get().then(lbcStore => {
    if (!lbcStore.exists) {
      console.log('No such product!');
    } else {
      console.log('Document data:', product.data());
    }
    console.log('storeInfo:')
    console.log(lbcStore.data())
    return {message: 'Success'}
  })    
  .catch((error) => {
    // To be adapted here, see https://firebase.google.com/docs/functions/callable#handle_errors
    console.log(error);
  });
};

另外,请注意,您应该为错误处理部分调整代码,请参阅 https://firebase.google.com/docs/functions/callable#handle_errors

最后,确保你的 db 常量定义为 admin.firestore(); .

console.log() 在特定函数的 Log

https://console.firebase.google.com/u/0/project/<project-name>/functions/logs

*改变 <project-name> 给你的(没有 < >

*您可能需要选择特定的功能/日志级别才能实时查看日志。

您还可以使用文档中所述的查看日志:

https://firebase.google.com/docs/functions/writing-and-viewing-logs#viewing_logs

使用firebase工具查看日志

firebase functions:log

查看特定函数的日志

firebase functions:log --only <FUNCTION_NAME>
