通过 Twilio 发送短信让它选择带有 MessagingServiceSid 的发件人号码不起作用 [英] Sending an SMS through Twilio letting it chose the From number with a MessagingServiceSid doesn't work

问题描述

我正在尝试使用 twilio 发送短信，但没有指定特定的发件人号码，而是让 Copilot 为我选择最佳号码(如 https://www.twilio.com/docs/api/rest/sending-messages#post-parameters-conditional).

I'm trying to send an SMS using twilio, without specifying a specific From number, instead letting Copilot chose the best number for me (as documented in https://www.twilio.com/docs/api/rest/sending-messages#post-parameters-conditional).

但是，在发送请求时，Twilio REST API 会抱怨我没有指定发件人编号.正如预期的那样，指定发件人编号有效.但是我想避免这种情况，以便在将来需要更多数字时更加灵活.我误解了文档吗?

However, when sending a request, the Twilio REST API complains that I did not specify a From number. Specifying a From number, as expected, works. But I'd like to avoid this to be more flexible in case I need more numbers down the road. Am I misunderstanding the documentation ?

我使用 HTTPie 来测试 API.完整的请求/响应:

推荐答案

我可以看到您在 MessageService 中有一个数字，但是看起来您正在使用不支持 使用 MessageService 发送.

I can see that you have a number in the MessageService, however it looks like you are using the old deprecated endpoint that does not support sending with the MessageService.

您有:/2010-04-01/Accounts/$ACCOUNT_SID/SMS/Messages.json

您应该使用:/2010-04-01/Accounts/$ACCOUNT_SID/Messages.json

试试看，让我知道它是怎么回事.

Give that a try and let me know how it goes.
