是否有任何模块可以从azure V4函数执行express api而不是模块“azure-aws-serverless-express”？

Question

当我从 azure 函数模型 V4 调用执行时，获取请求 url 为未定义，

auzurev4\src 函数\httpTrigger1.ts

import { InvocationContext, HttpRequest } from "@azure/functions";
import { app } from "@azure/functions";
import azureFunctionHandler from "azure-aws-serverless-express";
import expressApp from "../../app";

const httpTrigger: any = async function (
  context: InvocationContext,
  req: HttpRequest
): Promise<void> {
  await azureFunctionHandler(expressApp)(context, req);
};

export default app.http("httpTrigger1", {
  methods: ["GET"],
  route: "{*segments}",
  handler: httpTrigger,
});

auzurev4 pp.ts

import express, { Request, Response } from "express";
const app = express();

app.get("/api/user", (req: Request, res: Response) => {
  res.send("Hello from Express!");
});

export default app;

尝试 api url

http://localhost:7071/api/user

我使用 azure-aws-serverless-express 成功从 auzure v3 获得了 api 响应，但在执行 azure v4 时出现此错误。所以请指导我解决这个问题或者请分享任何其他替代模块

错误：

您可以直接使用以下代码，而不是使用

azure-aws-serverless-express

：-

httpTrigger1.ts：-

import { app, HttpRequest, HttpResponseInit, InvocationContext } from "@azure/functions";
import appInstance from "../../app"; 

export async function httpTrigger1(request: HttpRequest, context: InvocationContext): Promise<HttpResponseInit> {
    context.log(`Http function processed request for url "${request.url}"`);

    try {
        const response = await appInstance.get("/api/user")(request, null);

        return {
            body: response.body
        };
    } catch (error) {
        return {
            status: 500,
            body: JSON.stringify({ message: "Error calling Express API", error: error.message })
        };
    }
};

app.http('httpTrigger1', {
    methods: ['GET', 'POST'],
    authLevel: 'anonymous',
    handler: httpTrigger1
});

app.ts：-

import express, { Request, Response } from "express";

const app = express();

export function createUserHandler() {
    return (req: Request, res: Response) => {
        res.send("Hello from Express!");
    };
}
export default app;

输出：-
