Install extension

你安装的扩展 NuGet 包取决于你在函数应用中使用的 C# 模式：

扩展的功能因扩展版本而异：

Install bundle

Starting with Functions version 2.x, the HTTP extension is part of an extension bundle, which is specified in your host.json project file. To learn more, see extension bundle.

可以使用以下 C# 模式之一创建 C# 函数：

• 独立辅助角色模型：编译的 C# 函数，该函数在独立于运行时的工作进程中运行。 需要隔离的工作进程来支持长期支持 （LTS） 和非 LTS 版本的 .NET 和 .NET Framework 上运行的 C# 函数。
• In-process model: Compiled C# function that runs in the same process as the Azure Functions runtime.
• C# script: Used primarily when you create C# functions in the Azure portal.

using Microsoft.Extensions.Logging;
using Newtonsoft.Json.Linq;
using Twilio.Rest.Api.V2010.Account;
using Twilio.Types;
namespace TwilioQueueOutput
{
    public static class QueueTwilio
    {
        [FunctionName("QueueTwilio")]
        [return: TwilioSms(AccountSidSetting = "TwilioAccountSid", AuthTokenSetting = "TwilioAuthToken", From = "+1425XXXXXXX")]
        public static CreateMessageOptions Run(
        [QueueTrigger("myqueue-items", Connection = "AzureWebJobsStorage")] JObject order,
        ILogger log)
        {
            log.LogInformation($"C# Queue trigger function processed: {order}");

            var message = new CreateMessageOptions(new PhoneNumber(order["mobileNumber"].ToString()))
            {
                Body = $"Hello {order["name"]}, thanks for your order!"
            };

            return message;
        }
    }
}

The following example shows a Twilio output binding in a function.json file and a JavaScript function that uses the binding.

Here's binding data in the function.json file:

Example function.json:

{
  "type": "twilioSms",
  "name": "message",
  "accountSidSetting": "TwilioAccountSid",
  "authTokenSetting": "TwilioAuthToken",
  "from": "+1425XXXXXXX",
  "direction": "out",
  "body": "Azure Functions Testing"
}

JavaScript 代码如下所示：

module.exports = async function (context, myQueueItem) {
    context.log('Node.js queue trigger function processed work item', myQueueItem);

    // In this example the queue item is a JSON string representing an order that contains the name of a
    // customer and a mobile number to send text updates to.
    var msg = "Hello " + myQueueItem.name + ", thank you for your order.";

    // Even if you want to use a hard coded message in the binding, you must at least
    // initialize the message binding.
    context.bindings.message = {};

    // A dynamic message can be set instead of the body in the output binding. The "To" number 
    // must be specified in code. 
    context.bindings.message = {
        body : msg,
        to : myQueueItem.mobileNumber
    };
};

完整的 PowerShell 示例当前不可用于 SendGrid 绑定。

The following example shows how to send an SMS message using the output binding as defined in the following function.json.

    {
      "type": "twilioSms",
      "name": "twilioMessage",
      "accountSidSetting": "TwilioAccountSID",
      "authTokenSetting": "TwilioAuthToken",
      "from": "+1XXXXXXXXXX",
      "direction": "out",
      "body": "Azure Functions Testing"
    }

可以将序列化的 JSON 对象传递到 func.Out 参数以发送短信。

import logging
import json
import azure.functions as func

def main(req: func.HttpRequest, twilioMessage: func.Out[str]) -> func.HttpResponse:

    message = req.params.get('message')
    to = req.params.get('to')

    value = {
      "body": message,
      "to": to
    }

    twilioMessage.set(json.dumps(value))

    return func.HttpResponse(f"Message sent")

The following example shows how to use the TwilioSmsOutput annotation to send an SMS message. to、from 和 body 的值在属性定义中是必需的，即使以编程方式重写它们也是如此。

package com.function;

import java.util.*;
import com.microsoft.azure.functions.annotation.*;
import com.microsoft.azure.functions.*;

public class TwilioOutput {

    @FunctionName("TwilioOutput")
    public HttpResponseMessage run(
            @HttpTrigger(name = "req", methods = { HttpMethod.GET, HttpMethod.POST },
                authLevel = AuthorizationLevel.FUNCTION) HttpRequestMessage<Optional<String>> request,
            @TwilioSmsOutput(
                name = "twilioMessage",
                accountSid = "AzureWebJobsTwilioAccountSID",
                authToken = "AzureWebJobsTwilioAuthToken",
                to = "+1XXXXXXXXXX",
                body = "From Azure Functions",
                from = "+1XXXXXXXXXX") OutputBinding<String> twilioMessage,
            final ExecutionContext context) {

        String message = request.getQueryParameters().get("message");
        String to = request.getQueryParameters().get("to");

        StringBuilder builder = new StringBuilder()
            .append("{")
            .append("\"body\": \"%s\",")
            .append("\"to\": \"%s\"")
            .append("}");

        final String body = String.format(builder.toString(), message, to);

        twilioMessage.setValue(body);

        return request.createResponseBuilder(HttpStatus.OK).body("Message sent").build();
    }
}

Attributes

Both in-process and isolated worker process C# libraries use attributes to define the output binding. C# 脚本改为使用 function.json 配置文件。

Annotations

The TwilioSmsOutput annotation allows you to declaratively configure the Twilio output binding by providing the following configuration values:

+

Place the TwilioSmsOutput annotation on an OutputBinding<T> parameter, where T may be any native Java type such as int, String, byte[], or a POJO type.

Configuration

The following table explains the binding configuration properties that you set in the function.json file, which differs by runtime version:
