不能将req (events.APIGatewayProxyRequest类型的变量)用作adapter.ProxyWithContext参数中的core.SwitchableAPIGatewayRequest值

Question

我是刚到戈朗来的。我似乎无法提供使用adapter.ProxyWithContext所需的论据。根据这个https://pkg.go.dev/github.com/awslabs/aws-lambda-go-api-proxy@v0.13.0/gorillamux#GorillaMuxAdapter.ProxyWithContext，它应该接受API代理事件或API V2事件。

import (
    "context"
    "github.com/aws/aws-lambda-go/events"
    "github.com/aws/aws-lambda-go/lambda"
    routerProxy "github.com/awslabs/aws-lambda-go-api-proxy/gorillamux"
)

var adapter *routerProxy.GorillaMuxAdapter

func main() {
    cfg := config.NewConfig()
    s := app.NewApp(cfg, log)

    adapter = routerProxy.New(s.SetupRoutes())
    lambda.Start(lambdaHandler) // execute lambda and the specific lead handler
}

func lambdaHandler(ctx context.Context, req events.APIGatewayProxyRequest) (events.APIGatewayProxyResponse, error) {
    c, err := adapter.ProxyWithContext(ctx, req)
    return c, err
}


i'm having this error: 
``var req events.APIGatewayProxyRequest
cannot use req (variable of type events.APIGatewayProxyRequest) as core.SwitchableAPIGatewayRequest value in argument to adapter.ProxyWithContextcompilerIncompatibleAssign

正如批注mkopriva所指出的，您不能直接将events.APIGatewayProxyRequest传递给adapter.ProxyWithContext。

您需要创建SwitchableAPIGatewayRequest的新实例并将其传递给ProxyWithContext。

这应该可以解决您的问题：

import "github.com/awslabs/aws-lambda-go-api-proxy/core"

[...]

func lambdaHandler(ctx context.Context, req events.APIGatewayProxyRequest) (events.APIGatewayProxyResponse, error) {
    return adapter.ProxyWithContext(ctx, *core.NewSwitchableAPIGatewayRequestV1(&req))
}
