amazon-web-services - 无法识别的令牌“$context”：期待（“true”、“false”或“null”）AWS VTL

Question

我正在传递一个context-token通过 graphql 客户端调用的标头，我试图将其从标头中拉出以使用以下 vtl 传递给 lambda：

{
    "version": "2017-02-28",
    "operation": "Invoke",
    "payload": {
        "type": "Query",
        "resolver": "apiContext",
        "arguments":  $utils.toJson($context.arguments),
        "contextToken": $context.request.headers.context-token
    }
}

这对我有用。

{
    "version": "2017-02-28",
    "operation": "Invoke",
    "payload": {
        "type": "Query",
        "resolver": "apiContext",
        "arguments":  $utils.toJson($context.arguments),
        "contextToken": "$context.request.headers.get("context-token")"
    }
}
