前言

在这篇文章中，我将分享如何利用ChatGPT 4.0辅助论文写作的技巧，并根据网上的资料和最新的研究补充更多好用的咒语技巧。

GPT4的官方售价是每月20美元，很多人并不是天天用GPT，只是偶尔用一下。

如果调用官方的GPT4接口，就可以按使用量付费，用多少付多少，而且没有3个小时内只能提问50条的使用限制。

但是对很多人来说调用接口是比较麻烦的。如果开发一个网站，后台调用GPT4的接口，大家一起用，

分摊一下服务器的成本，就比较划算了。见文末【参考链接】

nodejs后台代码：

let baseApiKeyOnServer = 'Basic xxx'
const chatGetWeather = async (req, res) => {
  let { city = '北京', extensions = 'all' } = req.query
  let headers = req.headers
  let authorization = req.headers?.authorization
  console.log('天气', city, headers, req.query)
  if (authorization === baseApiKeyOnServer) {
    let resultCity = cityList.find((item) => item.name.includes(city))
    let cityCode = '110000'
    if (resultCity && resultCity.adcode) {
      cityCode = resultCity.adcode
    }
    console.log('高德天气查询', city, cityCode, extensions)
    //	extensions可选值：base/all base:返回实况天气 all:返回预报天气
    let result = await axios.get(
      `https://restapi.amap.com/v3/weather/weatherInfo?key=${weatherApiKey}&city=${cityCode}&extensions=${extensions}`
    )
    const searchResult = result.data
    let functionResponse
    if (searchResult && Array.isArray(searchResult.lives)) {
      functionResponse = `${JSON.stringify(searchResult.lives)}`
    } else if (searchResult && Array.isArray(searchResult.forecasts)) {
      functionResponse = `${JSON.stringify(searchResult.forecasts)}`
    } else {
      functionResponse = `${JSON.stringify(searchResult)}`
    }
    res.send({
      code: 200,
      data: {
        city,
        headers,
        result: functionResponse,
      },
      message: '成功',
    })
  } else {
    res.send({
      code: 400,
      message: '失败：参数headers.authorization',
    })
  }
}
