[英]How to specify request type to AWS lambda invocation with boto3?
我有一个 lambda function 接受GET
, POST
和DELETE
请求。 我想使用 python 的boto3
库来调用它。
根据文档,可以使用 boto3 调用 lambda boto3
,如下所示:
response = client.invoke(
FunctionName='string',
InvocationType='Event'|'RequestResponse'|'DryRun',
LogType='None'|'Tail',
ClientContext='string',
Payload=b'bytes'|file,
Qualifier='string'
)
但是如何指定我的请求类型? 我的有效负载是否应该包含一个包含GET
/ POST
/ DELETE
的字段method
? 或者我应该通过ClientContext
对象/字符串传递它吗?
您需要在 Payload Parameter 中指定 HTTP 请求
{
"version": "2.0",
"routeKey": "$default",
"rawPath": "/my/path",
"rawQueryString": "parameter1=value1¶meter1=value2¶meter2=value",
"cookies": [
"cookie1",
"cookie2"
],
"headers": {
"header1": "value1",
"header2": "value1,value2"
},
"queryStringParameters": {
"parameter1": "value1,value2",
"parameter2": "value"
},
"requestContext": {
"accountId": "123456789012",
"apiId": "api-id",
"authentication": {
"clientCert": {
"clientCertPem": "CERT_CONTENT",
"subjectDN": "www.example.com",
"issuerDN": "Example issuer",
"serialNumber": "a1:a1:a1:a1:a1:a1:a1:a1:a1:a1:a1:a1:a1:a1:a1:a1",
"validity": {
"notBefore": "May 28 12:30:02 2019 GMT",
"notAfter": "Aug 5 09:36:04 2021 GMT"
}
}
},
"authorizer": {
"jwt": {
"claims": {
"claim1": "value1",
"claim2": "value2"
},
"scopes": [
"scope1",
"scope2"
]
}
},
"domainName": "id.execute-api.us-east-1.amazonaws.com",
"domainPrefix": "id",
"http": {
"method": "POST",
"path": "/my/path",
"protocol": "HTTP/1.1",
"sourceIp": "IP",
"userAgent": "agent"
},
"requestId": "id",
"routeKey": "$default",
"stage": "$default",
"time": "12/Mar/2020:19:03:58 +0000",
"timeEpoch": 1583348638390
},
"body": "Hello from Lambda",
"pathParameters": {
"parameter1": "value1"
},
"isBase64Encoded": false,
"stageVariables": {
"stageVariable1": "value1",
"stageVariable2": "value2"
}
}
好吧,当您调用 lambda function 时,它没有定义请求类型的选项。
解决方法是 - 您可以在有效负载中传递它并在 lambda function 中访问它。
否则,理想的方法是使用 HTTP 请求调用 function,如已经建议的那样。
