AWS Lambda 错误：无法解压缩上传的文件

Question

我正在尝试使用 node.js 的 aws-sdk 包更新我的 lambda 函数中的代码。所以我编写了以下脚本来运行以部署代码

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);
});

问题是，当我运行脚本时，出现以下错误：

{ InvalidParameterValueException: Could not unzip uploaded file. Please check your file, then try to upload again.

我尝试从我的计算机和 CircleCI 部署 zip 文件，我也尝试使用 AWS CLI，结果都相同。

我在 zip 文件和 config.json 中有我需要的一切。我在这里做错了什么？

Answer 1

ZipFile需要是一个Buffer.

这意味着您必须读取文件并将其转换为Buffer对象。

您可以使用fs.readFile()或fs.readFileSync()来执行此操作。
