我搜索了AWS Lambda文檔,但找不到我的問題的答案。AWS Lambda Payloads
有沒有一種方法可以從Lambda函數(用node.js編寫)訪問整個請求體?
event
參數似乎只包含解析的JSON屬性。

您的請求正文需要使用XML或JSON以便能夠在您的Lambda
函數中訪問它。您需要指定它在API Gateway
儀表板的Integration Request
部分中的處理/映射和傳遞方式。
作爲替代方案,如果它更適合您的用例,您可以考慮將lambda設置爲簡單代理。我發現最近有更多人使用這種技術。
http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-set-up-simple-proxy.html
請求等以下幾點:
POST /testStage/hello/world?name=me HTTP/1.1
Host: gy415nuibc.execute-api.us-east-1.amazonaws.com
Content-Type: application/json
headerName: headerValue
{
"a": 1
}
會倒閉以下事件數據發送到您的AWS lambda表達式:
{
"message": "Hello me!",
"input": {
"resource": "/{proxy+}",
"path": "/hello/world",
"httpMethod": "POST",
"headers": {
"Accept": "*/*",
"Accept-Encoding": "gzip, deflate",

"queryStringParameters": {

},
"body": "{\r\n\t\"a\": 1\r\n}",

}
}
現在,您可以訪問所有的頭,url params,body等在每個請求中。
您可以在AWS Lambda中訪問正文映射模板中的請求正文。
Integration Request
Integration Request
,打開Body Mapping Templates
面板Content Type
application/json
的application/json
項目{
"body" : $input.json('$')
}
之後,你可以訪問請求主體作爲你的Node.js lambda函數event.body
。
您可以在不使用API網關的情況下自定義請求參數嗎? – user2976753
