Introduction

The HTTP module sends a POST request to the corresponding address, with json parameters in the body. The specific parameters can be customized. It also receives a json response value, with customizable fields. In the above figure, we define an input parameter: extracted field (key is appointment, type is string), and an output parameter: extraction result (key is response, type is string).

So, the curl command for this request is:

curl --location --request POST 'https://xxxx.laf.dev/appointment-lab' \
--header 'Content-Type: application/json' \
--data-raw '{
"appointment":"{\"name\":\"小明\",\"time\":\"2023/08/16 15:00\",\"labname\":\"子良A323\"}"
}'

The response is:

{
  "response": "您已经有一个预约记录了，每人仅能同时预约一个实验室:\n  姓名：小明\n  时间: 2023/08/15 15:00\n  实验室: 子良A323\n      "
}

If you don't want to deploy additional services, you can use laf to quickly build interfaces, write and send them without deployment

Here is a request example:

import cloud from '@lafjs/cloud';
const db = cloud.database();
export default async function (ctx: FunctionContext) {
  const { appointment } = ctx.body;
  const { name, time, labname } = JSON.parse(appointment);
  const missData = [];
  if (!name) missData.push('你的姓名');
  if (!time) missData.push('需要预约的时间');
  if (!labname) missData.push('实验室名称');
  if (missData.length > 0) {
    return {
      response: `请提供: ${missData.join('、')}`
    };
  }
  const { data: record } = await db
    .collection('LabAppointment')
    .where({
      name,
      status: 'unStart'
    })
    .getOne();
  if (record) {
    return {
      response: `您已经有一个预约记录了，每人仅能同时预约一个实验室:
姓名：${record.name}
时间: ${record.time}
实验室: ${record.labname}
`
    };
  }
  await db.collection('LabAppointment').add({
    name,
    time,
    labname,
    status: 'unStart'
  });
  return {
    response: `预约成功。
姓名：${name}
时间: ${time}
实验室: ${labname}
`
  };
}
