Question

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

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，所有结果都相同。

我在zip文件和config.json中拥有所需的一切。我在这里做错了什么？

Answer 1

Buffer必须是Buffer。

这意味着您必须阅读该文件并将其转换为onChange={event => this.setState({ email:event.target.value })}对象。

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

Answer 2

我遇到了这个问题并解决了。

好像您正在压缩zip文件。这就是为什么它无法再次压缩它。

PS：如果您使用的是AWS-S3，请取消选中“ GZIP文件”选项。

Answer 3

您的ZipFile参数不正确，它必须是缓冲区。尝试更改为：

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 4

Node js。使用像

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

AWS Lambda错误：无法解压缩上传的文件
