使用 firebase 函数将数据推送到 Firestore

您好，我是新的 firebase 函数，并尝试将数据推送到 firestore，通过下面的代码，我可以将消息推送到 firestore 并且它正在工作，

exports.addMessage = functions.https.onRequest(async (req, res) => {
  // Grab the text parameter.
  const original = req.query.text;
  // Push the new message into Firestore using the Firebase Admin SDK.
  const writeResult = await admin.firestore().collection('messages').add({original: original});
  // Send back a message that we've successfully written the message
  res.json({result: `Message with ID: ${writeResult.id} added.`});
});

通过这个网址我可以推送文本

http://localhost:5001/myProj/us-central1/addMessage?text=sss

我需要将一些数据推送到对象数组中来代替文本，我需要对上面的代码进行哪些更改。

对象如：

data: {  booking_id: "0",
         channels: "4",
        country: "GB", 
        date: "2020-05-12",
        currencies: "GBP",
        total: "5000"    } 

                                       
                           

如果您想在 Cloud Function 中传递对象，则应将其添加到 POST 请求的正文中并按照中所述进行解析这部分文档 https://firebase.google.com/docs/functions/http-events#read_values_from_the_request并在此详细说明官方样本 https://github.com/firebase/functions-samples/tree/main/quickstarts/time-server（见下文代码行 https://github.com/firebase/functions-samples/blob/3515b7f38a3c598cdb20152a263372e81719ecda/quickstarts/time-server/functions/index.js#L69).

更具体地说，在云功能中您应该执行以下操作：

const booking_id = req.body.booking_id;
const channels = req.body.channels;
//...

并通过curl调用它，您应该执行以下操作：

curl -H 'Content-Type: application/json' /
     -d '{"booking_id": "0", "channels": "4", "country": "GB", ...}' /
