从 Azure Function 发送 SMS Nexmo 出错

Question

I try to send the SMS from Azure Function, it show the error. But if i do in Web or console app the sms succesfully sent. The error is this:

System.TypeInitializationException:''Nexmo.Api.Configuration' 的类型初始化器抛出异常。'

MissingMethodException: 找不到方法：'Microsoft.Extensions.Configuration.IConfigurationBuilder Microsoft.Extensions.Configuration.MemoryConfigurationBuilderExtensions.AddInMemoryCollection(Microsoft.Extensions.Configuration.IConfigurationBuilder, System.Collections.Generic.IEnumerable1<System.Collections.Generic.KeyValuePair2>)'。

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
var client = new Nexmo.Api.Client(creds: new Credentials(Api_KEY, Api_Secret));
                var results = client.SMS.Send(request: new SMS.SMSRequest()
                {
                    from = nexmo.Sender,
                    text = nexmo.Msg,
                    to = nexmo.Receiver
                });

我意识到这是一个老问题，但我注意到它仍然没有被接受。

我刚刚使用下面的代码将最新版本的 .Net SDK (5.9.0) 与 Functions v1、v3 和 v4 一起使用，没有任何问题

using Vonage;
using Vonage.Request;
using Vonage.Messaging;

var credentials = Credentials.FromApiKeyAndSecret("abcd123efg", "abcdefgfgfgfgf");

 var VonageClient = new VonageClient(credentials);
 var response = VonageClient.SmsClient.SendAnSms(new SendSmsRequest()
 {
     To = "0123456789",
     From = "Vonage APIs",
     Text = "A text message sent using the Vonage SMS API"
  });

我还能够按照库克先生的方法运行新的 WhatsApp API。

public bool Send(Message msg)
    {
        var task = SendAsync(msg);
        task.Wait();
        return task.Result;
    }

    public async Task<bool> SendAsync(Message msg)
    {
        var requestJson = CreateJson(msg);
        Console.WriteLine(requestJson);
        var content = new StringContent(requestJson);
        content.Headers.ContentType = MediaTypeHeaderValue.Parse("application/json");
        var client = new HttpClient();            

        try
        {
            HttpResponseMessage response = await client.PostAsync("https://messages-sandbox.nexmo.com/v0.1/messages", content);
            string responseJson = await response.Content.ReadAsStringAsync();
            return MessageSucceeded(responseJson);
        }
        catch
        {
            return false;
        }
    }

    private string CreateJson(Message msg)
    {
        JObject request = new JObject();
            JObject from = new JObject();
                from.Add("type", "whatsapp");
                from.Add("number", "14157386170");
            request.Add("from", from);


            JObject to = new JObject();
                to.Add("type", "whatsapp");
                to.Add("number", ConnectionData);
            request.Add("to", to);

            JObject message = new JObject();
                JObject content = new JObject();
                    content.Add("type", "text");
                    content.Add("text", msg.Text);
                message.Add("content", content);
            request.Add("message", message);
        return request.ToString();
    }

    private bool MessageSucceeded(string json)
    {
        var obj = JObject.Parse(json);
        JToken token;
        return obj.TryGetValue("message_uuid", out token);
    }

沙盒测试的 RequestJson 是：

{ 
    "from": { "type": "whatsapp", "number": "14157386170" }, 
    "to": { "type": "whatsapp", "number": "YOUR_WHITELIST_NUMBER" }, 
    "message": { 
        "content": { "type": "text", "text": "Test succeeded. Congrats" }
    }
}

如果请求成功，ResponseJson 将包含一个 message_uuid。我只检查是否包含它

{"message_uuid": "e6859d67-1a94-44c4-bf09-a3e3fa7f8691"}

我遇到了同样的问题，似乎 Nexmo.Csharp.Client 包在 Azure Functions 上无法正常工作。这可能是因为其中一个程序集与 Azure 不兼容（并非全部兼容）或某些配置设置在 Azure Functions 上不受支持。

我对安装了多少参考/程序集感到惊讶：

安装包 Nexmo.Csharp.Client

所以我放弃了尝试找出原因。相反，一个更简单的解决方案是创建自己的 HttpClient 并直接使用 REST API（这可能是重量级包所做的）。

        var client = new HttpClient();

        var requestContent = new FormUrlEncodedContent(new[] {
            new KeyValuePair<string, string>("api_key", "YOURKEY"),
            new KeyValuePair<string, string>("api_secret", "YOURSECRET"),
            new KeyValuePair<string, string>("to", "TO!!!"),
            new KeyValuePair<string, string>("from", "MisterCook"),
            new KeyValuePair<string, string>("text", "MisterCook Says Hi")

        });

        HttpResponseMessage response = await client.PostAsync(
            "https://rest.nexmo.com/sms/json",
            requestContent);

        HttpContent responseContent = response.Content;

        using (var reader = new StreamReader(await responseContent.ReadAsStreamAsync()))
        {
            // If you need it... 
        }

这将使您免于部署庞大的 Nexmo.Csharp.Client 包部署并在 Azure Functions 中工作。

如果它在本地或在其他环境中工作，那么代码是正确的。特别是对于 Azure Functions，我会检查依赖项是否按预期安装，并且 API 密钥等变量是否具有您预期的值（添加一些日志记录来测试这一点）——这些在无服务器上下文中的工作方式不同。希望对您有所帮助！
