[Gatsby App-> AWS Lambda到Google Auth返回Gatsby

Question

[我有一个点击操作，将获取请求发送到运行Google auth脚本的AWS Lambda函数，然后返回一个URL进行授权并返回到获取请求，并使用window.location将我发送给Google以进行授权，授权，目前我已将其发送回同一个lambda。我不能只是将其发送回Gatsby站点，因为google需要auth重定向URL来返回200状态代码，而且我不能仅在我的站点上创建一个页面，例如/ auth进行重定向。因此，一旦Im重定向到原始lambda，授权代码就会附加到网址中。到目前为止，一切正常。

我坚持的是下一步。

A）如何将用户重定向回Gatsby网站？

B）我是否将该身份验证（从url参数中提取出来）存储在我可以使用faundDB的数据库中，我很熟悉那和lambda函数。

C）并且我应该将google发送到一个单独的lambda，然后将我的提取请求发送给它，这真的很重要。

我正在使用NodeJS Lambda

这是我的lambda

const { google } = require("googleapis");
// const axios = require('axios')
// const url = 'http://checkip.amazonaws.com/';
let response;

/**

 */
exports.lambdaHandler = async (event, context) => {
  try {
    const oauth2Client = new google.auth.OAuth2(
      "1fdsfas",
      "uiPCvLfsdfs",
      "https://fdsfa/test"
    );

    // generate a url that asks permissions for Blogger and Google Calendar scopes
    const scopes = ["https://www.googleapis.com/auth/calendar"];

    const url = oauth2Client.generateAuthUrl({
      // 'online' (default) or 'offline' (gets refresh_token)
      access_type: "offline",

      // If you only need one scope you can pass it as a string
      scope: scopes,
    });

    console.log(url);

    // const ret = await axios(url);
    response = {
      statusCode: 200,
      headers: {
        "Access-Control-Allow-Origin": "*",
      },
      body: JSON.stringify({
        message: "Hello World",
        urlAuth: url,
        // location: ret.data.trim()
      }),
    };
  } catch (err) {
    console.log(err);
    return err;
  }

  return response;
};

这是我的提取请求

const click = () => {
    fetch("http://fdsaf/test")
      .then(response => response.json())
      .then(response => {
        console.log(response.urlAuth)
        window.location.href = response.urlAuth
      })
  }

Answer 1

我知道了。我最终创建了第二个lambda来推送到数据库，作为google auth的调用bakc url。然后立即将301重定向到localhost。

// const axios = require('axios')
// const url = 'http://checkip.amazonaws.com/';
let response;
const faunadb = require("faunadb"); /* Import faunaDB sdk */

exports.lambdaHandler = async (event, context) => {
  try {
    // const ret = await axios(url);
    let code;
    if (event.queryStringParameters) {
      code = event.queryStringParameters.code;
    } else {
      code = "no code";
    }

    // Connect to the database
    const q = faunadb.query;
    const client = new faunadb.Client({
      secret: "fdsafa",
    });

    await client
      .query(q.Create(q.Collection("AuthUrl"), { data: { title: code } }))
      .then((ret) => console.log(ret));


    response = {
      statusCode: 301,
      headers: {
        Location: "http://localhost:8000",
      },
    };
  } catch (err) {
    console.log(err);
    return err;
  }

  return response;
};
