asp.net-core - aws lambda api gatewayc AmazonDynamoDBException

问题描述

我的应用程序在 AWS 中使用 c# .net 核心。在我探索添加 cloudfront 并添加另一个用户之前，我有 lambda api正在工作。现在它不再工作了，我不知道如何修复（我只是 aws 的新手，只是能够通过我观看的视频教程完成所有这些）。因此，为了隔离，我删除了我刚刚创建的云端分发，因为它可能是原因，但它仍然无法正常工作，我还删除了用户，因为错误暗示它可能正在寻找“共享凭据”，但仍然没有不行。我的 api 在本地工作，并直接对 dynamodb 执行 CRUD，所以我知道我的 dynamodb 和我的 aws 访问配置没有问题。它仅在部署时中断。

更新我的 lambdas

LambdaDynamoDBRole - DynamoReadWriteAccess

当我们在这里时，我不确定指向我的本地文件夹是否正确，我之前没有注意到它仍在工作，但我没有在我的配置中修改将它指向本地与否，但下面是摘录。

这是我的招摇错误的图像：

下面是我在调用我的 api 的 GET 后从 cloudwatch 获取的整个错误日志：

知道如何解决这个问题吗？谢谢

解决方案

如果它在您的本地工作，我假设您可能已经使用 AWSCredentials 类之一在代码中硬编码了 AWS 凭证。例如

new Amazon.Runtime.BasicAWSCredentials("","")

如果是这种情况，请删除所有硬编码的凭据。

at AWSServerlessPOS.Services.CategoryListService.ScanAsync(QueryRequest request) in C:\Users\Administrator\source\repos\AWSServerlessPOS\AWSServerlessPOS\Services\CategoryListService.cs:line 65

除非您为 Lambda 使用自定义运行时，否则上述行不应出现在 AWS 上。的默认运行时C#是基于 Linux 的，而且绝对不会有 Windows 路径系统。如果无法访问完整代码，我会假设一些硬编码也会导致此问题。
