10-22 15:29:40.897: …我有一个响应方法,看起来像我的Lambda函数:
def respond(err, res=None):
return {
'statusCode': 400 if err else 200,
'body': json.dumps(err) if err else json.dumps(res),
'headers': {
'Access-Control-Allow-Headers': 'content-type,X-Amz-Date,Authorization,X-Api-Key,X-Amz-Security-Token',
'Access-Control-Allow-Methods': 'POST, GET, DELETE',
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Credentials': True,
'Content-Type': 'application/json',
},
}
当我使用Postman的OPTIONS请求测试我的端点时,我收到500内部服务器错误.如果我从API网关控制台测试它,我另外得到这个:
Execution log for request test-request
Wed Jul 05 14:25:26 UTC 2017 : Starting execution for request: test-invoke-request
Wed Jul 05 14:25:26 UTC 2017 : HTTP Method: OPTIONS, Resource Path: /login
Wed Jul 05 14:25:26 UTC 2017 : Method request path: {}
Wed Jul 05 14:25:26 …我正在尝试为使用AWS Lambda的应用程序编写无服务器后端，并且遇到标题中的错误。使用API Gateway代理集成进行测试时会发生错误，但是在Lambda控制台中进行测试时，该功能可以正常工作。
这是错误：
{
"errorMessage":"string indices must be integers",
"errorType":"TypeError",
"stackTrace":[
[
"/var/task/auth_login.py",
17,
"lambda_handler",
"response = get_user(payload)"
],
[
"/var/task/shifty_utils/__init__.py",
22,
"get_user",
"table = dynamo.Table(user['company'] + '_users')"
]
]
}
这是发生情况的上下文：
def lambda_handler(event, context):
payload = event['body']
response = get_user(payload)
def get_user(user):
try:
table = dynamo.Table(user['company'] + '_users')
response = table.get_item(
Key={
'userId': user['userId'],
'position': user['position']
}
)
except ClientError as e:
print(e.response['Error']['Message'])
return {'message': e.response['Error']['Message']}
else:
return response
基本上，代理集成似乎是以JSON格式的字符串而不是dict的形式读取事件对象，但是如果我为此调整代码，就会发生以下情况：
{
"errorMessage":"the JSON object must be str, bytes …
