postman 无法查询CloudWatch日志AWS API端点

我正在尝试为我们的内部团队构建一个小型Web应用程序，用于查看我们的CloudWatch日志。现在，我还处于开发初期，只是尝试使用AWS API官方文档中指定的https://logs.us-east-1.amazonaws.com通过Postman访问日志。
我已经按照以下步骤设置了对端点的POST请求，并使用以下头：Postman Generated Headers
此外，在以下文件我已提供的行动在本职位请求的正文：{"Action": "DescribeLogGroups"}
使用AWS CLI，这工作正常，我可以看到我所有的日志组。
当我向https://logs.us-east-1.amazonaws.com发送这个请求时，我得到了：

{
    "Output": {
        "__type": "com.amazon.coral.service#UnknownOperationException",
        "message": null
    },
    "Version": "1.0"
}

状态码是200。
我尝试过的事情：

完全删除请求体->导致“内部服务器错误”
将/describeloggroups附加到没有正文的URL->导致“内部服务器错误”

我真的不知道我做错了什么。

最好的方法是将X-Amz-Target头设置为Logs_20140328.DescribeLogGroups。
下面是一个示例请求：https://docs.aws.amazon.com/AmazonCloudWatchLogs/latest/APIReference/API_DescribeLogGroups.html#API_DescribeLogGroups_Example_1_Request
下面是一个你可以尝试的 Postman 集合。将其保存为文件并使用File -> Import导入Postman。它还要求您在postman中设置credential和region变量。

尝试将其复制到json文件中，并将其导入Postman并添加缺少的变量。我试图在服务“日志”中获取DescribeLogGroups。在这里的文档www.example.com中查看https://docs.aws.amazon.com/AmazonCloudWatchLogs/latest/APIReference/API_DescribeLogGroups.html#API_DescribeLogGroups_Example_1_Request有关头和正文的更多信息。PS：会话令牌是可选的，我不需要它在我的情况下希望它适用于任何人谁

你们帮我找出了我做错了什么，谢谢！现在，我没有尝试下载文件并导入它（上面建议），因为我已经在Postman中设置好了。但是我看到我丢失了标题“Content-Encoding”“amz-1.0”。然后它起作用了。真不敢相信！：）
