Serverless and uploading image from Lambda endpoint to S3

Serverless and uploading image from Lambda endpoint to S3



I'm using the Serverless framework with Python. What I'm trying to accomplish is have an HTTP endpoint setup by Serverless and have that endpoint upload an image to S3. The client, Android, would upload an image from their phone and hit the endpoint with the image. I've been able to successfully upload to S3 but when I click on download for the image and try to open it, it appears to be corrupted.

I'm using the file_uploadobj function and it expects a file like object as its first argument. It should be noted that the type of event['body'] is unicode.


event['body']


unicode



Here is the code that I'm using to accomplish this upload.


import boto3

def upload_image(event, context):
headers, body = event['headers'] ,event['body']
client = boto3.client('s3', region_name='us-west-2')
filename = event['queryStringParameters']['filename']
tmp_filename = '/tmp/' + filename
file__ = open(tmp_filename, 'wb')
file__.write(body)
# file__.write(body.encode('utf-8'))
# file__.write(body.encode('base64'))
file__.close()
with open(tmp_filename, 'rb') as file_data:
client.upload_fileobj(file_data, 'bucket', filename, ExtraArgs='ContentType': 'image/jpeg')
return
'statusCode': 200,
'body': 'path': filename



Does anyone have any ideas as to what I'm doing wrong?



I've also tried the following using upload_file.


import base64

def upload_image(event, context):
headers, body = event['headers'] ,event['body']
client = boto3.client('s3', region_name='us-west-2')
filename = event['queryStringParameters']['filename']
tmp_filename = '/tmp/' + filename
with open(tmp_filename, 'wb') as file_descriptor:
file_descriptor.write(base64.b64decode(data))
client.upload_file(tmp_filename, 'bucket', filename, ExtraArgs='ContentType': 'image/jpeg')
return
'statusCode': 200,
'body': 'path': filename





can you look at the metadata of the object? What's the content-type and the size of the object?

@KendrickKesley here's the data of the body gist.github.com/Petesta/d1d0d18b0694923f29b97d747d22cff2. The content-type is multipart/form-data.
