azure function 应用程序环境的配置值

Question

您正在开发一个Azure Function App。您使用 Azure Function App 主机不支持的语言开发代码。代码语言支持 HTTP 原语。 您必须将代码部署到生产 Azure Function App 环境。 您需要配置应用程序以进行部署。 您应该使用哪些配置值？

请告知是否应该 代码 -> 自定义处理程序 -> 自定义 或者 Docker 容器 -> power shell 核心 -> 7.0

尝试了 Docker 容器 -> power shell core -> 7.0 但没有成功

Answer 1

为了使用自定义处理程序，请参阅此 Github 示例：-

示例 Http Golang 自定义处理程序：-

参考这里。

GoCustomHandler.go:-

package main

import (
    "fmt"
    "net/http"
    "log"
    "os"
    "strings"
)

func httpTriggerHandler(w http.ResponseWriter, r *http.Request) {
    if r.Header.Get("X-Forwarded-For") != "" {
        w.Write([]byte(strings.Split(r.Header.Get("X-Forwarded-For"),":")[0]))
    } else if r.Header.Get("Host") != "" {
        w.Write([]byte(strings.Split(r.Header.Get("Host"),":")[0]))
    } else if r.RemoteAddr != "" {
        w.Write([]byte(strings.Split(r.RemoteAddr,":")[0]))
    }
}

func main() {
    httpInvokerPort, exists := os.LookupEnv("FUNCTIONS_HTTPWORKER_PORT")
    if exists {
        fmt.Println("FUNCTIONS_HTTPWORKER_PORT: " + httpInvokerPort)
    }
    mux := http.NewServeMux()
    mux.HandleFunc("/httptrigger", httpTriggerHandler)
    log.Println("Go server Listening...on httpInvokerPort:", httpInvokerPort)
    log.Fatal(http.ListenAndServe(":"+httpInvokerPort, mux))
}

使用以下命令构建此代码：-

go build GoCustomHandler.go

将创建

GoCustomHandler.exe

，然后将其添加到

host.json

中，如下所示：-

{
    "version": "2.0",
    "extensionBundle": {
        "id": "Microsoft.Azure.Functions.ExtensionBundle",
        "version": "[1.*, 2.0.0)"
    },
    "customHandler": {
        "description": {
            "defaultExecutablePath": "GoCustomHandler.exe",
            "workingDirectory": "",
            "arguments": []
        },
        "enableForwardingHttpRequest": true
    }

}

正如您已经尝试使用

Powershell core

，直接创建一个 Http 触发器并针对 Http Primitive 用例进行调整，如下所示：-

run.ps1:-

# Azure Function PowerShell Script for HTTP Trigger

param($req, $TriggerMetadata)

# HTTP trigger function processed a request.
Write-Host "PowerShell HTTP trigger function processed a request."

# Interact with query parameters or the body of the request.
$name = $req.Query.Name
if (-not $name) {
    if ($req.Body) {
        $reqBody = $req.Body | ConvertFrom-Json
        $name = $reqBody.Name
    }
}

# Prepare the response body
if ($name) {
    $body = "Hello, $name. This HTTP triggered function executed successfully."
} else {
    $body = "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response."
}

# Create a response object using HTTP primitives
$response = [System.Net.Http.HttpResponseMessage]::new([System.Net.HttpStatusCode]::OK)
$responseContent = [System.Net.Http.StringContent]::new($body)
$response.Content = $responseContent

# Return the response
$response

输出：-

function.json:-

{
  "bindings": [
    {
      "authLevel": "anonymous",
      "type": "httpTrigger",
      "direction": "in",
      "name": "req",
      "methods": ["get", "post"]
    },
    {
      "type": "http",
      "direction": "out",
      "name": "res"
    }
  ]
}
