我的python 3 lambda函数从API网关接收以下事件（主体是base64编码的）：

我提交了一个带有图像和json字符串的表单作为multipart/form-data POST请求。我使用以下代码在服务器端处理它：

from requests_toolbelt.multipart import decoder
content_type_header = event['headers']['content-type']
postdata = base64.b64decode(event['body']).decode('iso-8859-1')
head = []
cont = []
for part in decoder.MultipartDecoder(postdata.encode('utf-8'), content_type_header).parts:
        head.append(part.headers)
        cont.append(part.content)  # content in binary format
print("\nJSON Part:-")
print(head[1])
print(cont[1])
print("\n")
print("File Part:-")
print(head[0])
print(cont[0])
print("\n")

with open("t.jpg", 'wb') as w:
        w.write(cont[0])

输出：-

JSON Part:-
{b'Content-Disposition': b'form-data; name="upload_json_string"'}
b'{ "data": "test"}'

File Part:-
{b'Content-Disposition': b'form-data; name="upload_filepath"; filename="img001 (3).jpg"', b'Content-Type': b'image/jpeg'}

但是输出的t.jpg（34 kb）不可读（损坏）并且比原始文件（29 kb）大。我在哪里犯了错误？我如何正确提取上传的文件（二进制数据）？

python-3.x

好吧，我得到了这个问题。这是由于不同的编码和解码。我用iso-8859-1解码，但用utf-8编码，这可能会导致二进制数据的错误，但不是文本数据。此外，这个额外的解码和编码步骤是不必要的，可以删除。然后，我能够复制确切的文件。

postdata = base64.b64decode(event['body'])

和

decoder.MultipartDecoder(postdata, content_type_header).parts

有了这个，我们就有了javascript客户端（或任何客户端）发送的multipart/form-data请求的代码，由AWS转换为base64，并由python后端处理。干杯。

我们遇到了同样的问题和效果。问题是postdata.encode（'utf-8'）进行转换，并尝试转换不可打印的字节。因此，Multipart-Headers不会转换，但二进制内容会被破坏。
在我们的例子中，AWS没有进行base64转换，所以base64.b64decode（event ['body']）没有帮助。
解决方案是配置API网关集成以使用正确的contentHandling我们在openapi定义上进行集成，它看起来像这样：

/contents:
    post:
      operationId: uploadContent
      description: "Upload content"
      tags:
        - Content
      requestBody:
        required: true
        content:
          multipart/form-data:
            schema:
              $ref: '#/components/schemas/ContentCreateCommand'
      responses:
        "201":
          description: "content uploaded"
       
      x-amazon-apigateway-integration: # API Gateway extension
        uri: !Sub "arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/arn:aws:lambda:${AWS::Region}:${AWS::AccountId}:function:NameYourFunction/invocations"
        passthroughBehavior: when_no_match
        httpMethod: "POST"
        contentHandling: "CONVERT_TO_TEXT"
        type: "aws_proxy"

关于集成的文档可以在这里找到https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-swagger-extensions-integration.html
也许这个设置可以在cdk/cloudformation或web控制台中找到
通过正确的内容处理，base64.b64decode（event ['body']）是最后剩下的和平。
