AWS Lambda 錯誤：無法解壓縮上傳的文件

Question

我正在嘗試使用 aws-sdk package 為 node.js 更新我的 lambda function 中的代碼。所以我編寫了以下腳本來運行以部署代碼

var AWS = require('aws-sdk');
AWS.config.loadFromPath('./config.json');
var lambda = new AWS.Lambda();

var params = {
    FunctionName: 'FunctionName',
    ZipFile: 'fileb://deploy_package.zip'
}

lambda.updateFunctionCode(params, function(err, data) {
    if (err) console.log(err, err.stack);
    else console.log(data);
});

問題是當我運行腳本時出現以下錯誤：

我嘗試從我的計算機以及 CircleCI 部署 zip 文件，我也嘗試使用 AWS CLI，所有結果都相同。

我在 zip 文件和 config.json 中擁有我需要的一切。 我在這里做錯了什么？

Answer 1

ZipFile需要是一個Buffer 。

這意味着您必須讀取文件並將其轉換為Buffer對象。

您可以使用fs.readFile()或fs.readFileSync()來執行此操作。

Answer 2

您的 ZipFile 參數不正確，它必須是緩沖區。 嘗試更改為：

var fs = require('fs');

var params = {
    FunctionName: 'FunctionName',
    ZipFile: fs.readFileSync('deploy_package.zip')
}

lambda.updateFunctionCode(params, function(err, data) {
    if (err) console.log(err, err.stack);
    else console.log(data);
});

Answer 3

我遇到了這個問題並解決了它。

看起來您正在壓縮 zip 文件。 這就是它無法再次壓縮的原因。

PS：如果您使用的是 AWS-S3，請取消選中“GZIP 文件”選項。

Answer 4

節點 js 。 使用喜歡

fs.readFile('lambda/function.zip', (err, data) => {
   if (data) {
      console.log(data)
      lambda.createFunction(data);
  }
})

Answer 5

我的解決方案與上述方案接近但略有不同。 也許是因為這種差異，它為我解決了這個問題：

import AWS from 'aws-sdk'
import fs from 'fs'

const file = fs.readFileSync(`myFileName.zip`)

const params = {
  Code: {
    ZipFile: Buffer.from(file),
  },
  ...
}

// Then standard SDK Lambda implementation:

const lambda = new AWS.Lambda({ apiVersion: '2015-03-31' })
lambda.createFunction(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});
