python发起请求提示UnicodeEncodeError

具体错误：

UnicodeEncodeError: 'latin-1' codec can't encode characters in position 73-74: Body ('测试') is not valid Latin-1. Use body.encode('utf-8') if you want to send it encoded in UTF-8.

解决：
对请求参数进行编码处理：
示例代码：

import requests
import json
import re
import pymysql
from tool.Mysql_connect import Mysql_operation
from tool.get_token import Crm_token

class test_demo(object):
    def __init__(self):
        self.op_mysql=Mysql_operation()
        self.token=Crm_token()
    def create_yixiang(self):
        url='http://xxx/customerAdjunctAdd'
        token=self.token.get_token()
        headers={"Content-Type":'application/x-www-form-urlencoded',
        "token":token}
        try:
            tel_num=self.op_mysql.sql_select('''select max(tel) from nc_customer_adjunct''')[0]['max(tel)'] #结果为str
        except Exception as error:
            print(error)
        a=1
        while a<3:
            tel_num=int(tel_num)+1
            a+=1
            data='customer_type=1&source=1&course_name_id=41&tel=%d&customer_name=测试3.1&sex=0&school=测试1&intro_id=0'%(tel_num)
            try:
                request1=requests.request("POST",url=url,headers=headers,data=data.encode()) #encode对请求编码处理：不处理接口会返回数据解析错误
                # print(data)
                response1=request1.json()
                print(headers)
                print(response1)
            except Exception as error:
                print(error)
if __name__=="__main__":
    Tm=test_demo()
    Tm.create_yixiang()
