[ERR_INVALID_ARG_TYPE]：第一个参数必须为字符串类型或Buffer的实例使用admin.authverifyIdToken

问题描述

我正在编写一个后端服务器（使用Node.js），以允许用户与Firebase进行交互。这是我到目前为止的内容：

• 我可以让用户通过管理员ADK创建他们的Firebase帐户（使用电子邮件和密码）；
• 我可以让用户通过REST API登录到他们的Firebase帐户（使用他们已经创建的电子邮件和密码）；并返回其idToken和refreshToken。

但是，我真的很奇怪，每当用户登录时，他们将拥有一个全新的idToken（持续1小时）；那么当新的idToken生成时，旧的会立即过期吗？因此，我认为我将使用firebase-admin SDK的verifyIdToken函数来执行我需要的操作。

问题是，即使当我输入新的idToken时，该函数也会失败。我真的不知道这是怎么回事。

如果我不执行捕获操作，则会出现以下错误：

(node:9240) UnhandledPromiseRejectionWarning: TypeError [ERR_INVALID_ARG_TYPE]: The first argument must be of type string or an instance of Buffer. Received type number (1598554002)

This error originated either by throwing inside of an async function without a catch block,or by rejecting a promise which was not handled with .catch().

(node:9240) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future,promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

这是我调用的函数：

async function verifyid(data,serverres) {
   serverres.write(data.id);
   await admin.auth().verifyIdToken(data.id).then(function(token) {
       serverres.write(token.exp)
   }).catch(function(error) {
       serverres.write(`Error code: ${error.code} \r\nError message: ${error.message}`);
   });
};

主要代码在这里：

var server = http.createServer(async function (req,res) {
    var urllink = url.parse(req.url,true);
    var urldata = urllink.query;

    if (Object.entries(urldata).length !== 0){
        switch(urldata.goal){
            //I dropped some cases here for clearance of the code
            case 'verifyid':
                await verifyid(urldata,res)
                res.end();
                break;
            default:
                res.write("Error: No action has been specified!")
                res.end();
        };
    };
  });


//initialize admin
var admin = require('firebase-admin');
var serviceAccount = require("./vimath_serviceAccountKey.json");
const { parse } = require('path');
const { userInfo } = require('os');

admin.initializeApp({
    credential: admin.credential.cert(serviceAccount),databaseURL: 'https://[my project].firebaseio.com'
});

server.listen(8080);

你们能看看吗？

非常感谢您

祝你有美好的一天，

解决方法

此行引发错误：

[Route("api/myRoute")]
[HttpPost]
    public async Task<IHttpActionResult> uploadExcelData
                (
                  [FromBody] Array excelRows
    )
            {
                 string[] aryExcelRowsObjects;

                 DataTable dataTable = new DataTable();
                 dataTable.Columns.Add(new DataColumn("name",typeof(string)));
                 dataTable.Columns.Add(new DataColumn("position",typeof(string)));
                 dataTable.Columns.Add(new DataColumn("sales",typeof(int)));

                 // this is the example I'm using and it no longer works as you can't use .Split() on an array. What should I change it to?
                 aryExcelRowsObjects = excelRows.Split(','); 

                // this is the example I'm using and I don't think it accounts for adding multiple columns into a row
                    foreach (string s in aryExcelRowsObjects)
                    {
                        dataTable.Rows.Add(s);
                    }

            }

该API需要一个字符串或一个Buffer，但是您要传递一个数字。
