Question

我正在尝试通过邮递员通过AWS API网关发布请求。我有aws IAM，它似乎正在工作。我可以发送任何请求，但lambda函数却返回200响应。

我想在正文中发送一个二进制文件，但是每当我向请求正文中添加任何内容，表单数据，原始或二进制数据时，我都会收到以下消息：

{
    "message": "The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.\n\nThe Canonical String for this request should have been\n'POST\ ..."
}

我尝试添加 image / png和application / octect-stream到Binary Media Types 并且还尝试指定其中仅包含一个字段的模型，但这也不起作用。

任何帮助将不胜感激。我曾尝试在AWS论坛上发帖，但是没有“发帖”，“问问题”或“创建”按钮来实际提出问题，因此请回到旧的可信任stackoverflow。

干杯。米奇。

Lambda函数：

import json
import os
import boto3

def lambda_handler(event, context):
    var = os.environ.get("a_variable")

    return {
        'statusCode': 200,
        'body': json.dumps({'message': 'Hello from Lambda 2!',
                            'echo': event,
                            'data': var})
    }
