API Gateway 验证内容类型标头

Question

如果内容类型不是 json api 网关不进行验证而只是通过。我使用代理集成，所以没有映射模板，只能使用“when_no_match”。我使用内联招摇。

我可以检查标题是否存在但不能检查值 - 我该怎么做？

/myMethod:
    post:
        x-amazon-apigateway-request-validator : "myvalidator"
        parameters:
        # How do I also validate Content-Type value is "application/json"
        - name: Content-Type
          in: header
          required: true

我想要 API 网关来验证这一点，所以我不必在代码中检查它

在Integration Request您的终端选项卡中，单击Mapping Templates，设置Request body passthrough为never，添加映射模板application/javascript，然后单击Method Request Passthrough旁边的下拉菜单Generate template。

这是招摇的片段： requestTemplates: application/json: | ## See http://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-mapping-template-reference.html ## This template will pass through all parameters including path, querystring, header, stage variables, and context through to the integration endpoint via the body/payload #set($allParams = $input.params()) { "body-json" : $input.json('$'), "params" : { #foreach($type in $allParams.keySet()) #set($params = $allParams.get($type)) "$type" : { #foreach($paramName in $params.keySet()) "$paramName" : "$util.escapeJavaScript($params.get($paramName))" #if($foreach.hasNext),#end #end } #if($foreach.hasNext),#end #end }, "stage-variables" : { #foreach($key in $stageVariables.keySet()) "$key" : "$util.escapeJavaScript($stageVariables.get($key))" #if($foreach.hasNext),#end #end }, "context" : { "account-id" : "$context.identity.accountId", "api-id" : "$context.apiId", "api-key" : "$context.identity.apiKey", "authorizer-principal-id" : "$context.authorizer.principalId", "caller" : "$context.identity.caller", "cognito-authentication-provider" : "$context.identity.cognitoAuthenticationProvider", "cognito-authentication-type" : "$context.identity.cognitoAuthenticationType", "cognito-identity-id" : "$context.identity.cognitoIdentityId", "cognito-identity-pool-id" : "$context.identity.cognitoIdentityPoolId", "http-method" : "$context.httpMethod", "stage" : "$context.stage", "source-ip" : "$context.identity.sourceIp", "user" : "$context.identity.user", "user-agent" : "$context.identity.userAgent", "user-arn" : "$context.identity.userArn", "request-id" : "$context.requestId", "resource-id" : "$context.resourceId", "resource-path" : "$context.resourcePath" } } passthroughBehavior: "never" httpMethod: "POST" type: "aws"
