我用 Python 构建了一个与 Twilio API 配合使用的问答游戏，因此我可以通过短信运行游戏到我的 Twilio 号码。我试图弄清楚如何传递一个响应，该响应将在发送电话收到时显示标准文本和表情符号。

我一直在努力理解 unicode 与 ascii 字符集以及 utf-8 中的编码和解码。我最后登陆的地方是下面的代码，它只是像手机上的常规字符串一样打印出 unicode 代码点。差距似乎在于如何隔离和传递电话可以解释的代码点。关于如何做到这一点的任何想法或指示？还是有人会推荐其他方法？

代码的当前状态如下：

# -*- coding: utf-8 -*-

from flask import render_template, flash, redirect, session, url_for, request, jsonify, g
from flask import Response
from app import app
from config import TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN
from twilio import twiml
from twilio.rest import TwilioRestClient
import re, random

client = TwilioRestClient(TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN)


def simplify_txt(submitted_txt):
    response_letters = re.sub(r'\W+', '', submitted_txt)
    return response_letters.lower()

@app.route("/quiz_game")
def quiz_game():

   response = twiml.Response()

    from_number = str(request.values.get('From', None))
    body = request.values.get('Body', None)
    simplify_body = simplify_txt(body)

    questions = { 
            0: "What word is shorter when you add two letters to it?",
            1: "If I drink, I die. If i eat, I am fine. What am I?",
            2: "What kind of tree is carried in your hand?",
            3: "Thanks for playing.",
            4: ""
    }

    # Stripped down answers to compare to text in case multiple word answer
    simplify_answers = { 
            1:"short", 
            2:"fire", 
            3:"palm",
            4:""
            }

    # Pretty print answers
    print_answers = { 
            1:"short", 
            2:"fire", 
            3:"palm",
            4:""
            }

    # if from_number not in track_user:
    if from_number not in session:
        session[from_number] = 0
        counter = session.get('counter', 0)
        counter += 1
        session['counter'] = counter
        message = "Shall we play a game? %s "  % questions[0]
    else:
        game_round = session['counter']

        if simplify_answers[game_round] == simplify_body:
            session[from_number] += 10
            score = session[from_number]

            message = "Correct Answer. You have %d points out of 30. %s" % (score, questions[game_round])

            message += unicode('u1f31f',"unicode_escape").encode('utf-8') 

        else:
            score = session[from_number]
            message = "Wrong answer. We were looking for %s. Your score is %d out of 30. %s" % (print_answers[game_round], score, questions[game_round])

        session['counter'] += 1


    if session['counter'] > 3:
        session.pop(from_number, None)
        session['counter'] = 0


    response.sms(message)

    return Response(str(response))

更新：部分问题是将 sms 方法应用于消息变量将其转换为不保留 unicode 代码点的 XML 格式。应用 messages.create 方法捕获并保存 unicode 代码点，以便移动设备对其进行解释。

对于修复，我将 Rob 的建议主要应用于代码的最后两行，将 response.sms 和 return 替换为 client.messages.create 并将 message 变量传递给 body 参数。我还将 u for unicode 应用于分配给消息变量的所有字符串，并将表情符号代码点/图像添加到消息中。这些使发短信的表情符号起作用。如果您想查看更新，请查看：https ://github.com/nyghtowl/Twilio_Quiz

关于如何使用 Twilio Python 模块发送表情符号的好问题。也喜欢战争游戏参考。我想我知道这里发生了什么。

发光星形符号的 unicode 值是 U+1F31F ，表示为 Python unicode 文字是u"\U0001F31F". 没有加号，它实际上是一个不同的代码点，不是发光的星星表情符号。

因此，要发送此特定示例，您将执行以下操作：

from twilio.rest import TwilioRestClient

# Set Twilio credentials
TWILIO_ACCOUNT_SID = "ACxxxxxxxxxxxxx"
TWILIO_AUTH_TOKEN = "yyyyyyyyyyyyyyyy"
TWILIO_NUMBER = "+15558675309"

# Instantiate Twilio REST client
client = TwilioRestClient(TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN)

# Send a glowing star emoji
client.messages.create(from_=TWILIO_NUMBER, to="+15556667777", body=u"Here is your tasty emoji: \U0001F31F")

希望有帮助！
