如何将JSON中的regex表达式传递给API？

{
  "regexPattern": "^\\d{3}-\\d{2}-\\d{4}$"
}

import json
import re

# 假设json_data是从API接收到的JSON字符串
json_data = '{"regexPattern": "^\\\\d{3}-\\\\d{2}-\\\\d{4}$"}'
data = json.loads(json_data)

# 将字符串转换为正则表达式对象
regex_pattern = re.compile(data['regexPattern'])

# 测试正则表达式
test_string = "123-45-6789"
if regex_pattern.match(test_string):
    print("匹配成功")
else:
    print("匹配失败")

{
  "regexPattern": "^\\\\d{3}-\\\\d{2}-\\\\d{4}$"
}

import json
import re
import requests

# 定义正则表达式
regex_pattern = "^\\d{3}-\\d{2}-\\d{4}$"

# 将正则表达式转换为JSON字符串
data = {
    "regexPattern": regex_pattern
}
json_data = json.dumps(data)

# 发送POST请求到API
response = requests.post('https://example.com/api', data=json_data, headers={'Content-Type': 'application/json'})

# 解析响应
if response.status_code == 200:
    response_data = response.json()
    received_regex = re.compile(response_data['regexPattern'])
    
    # 测试接收到的正则表达式
    test_string = "123-45-6789"
    if received_regex.match(test_string):
        print("匹配成功")
    else:
        print("匹配失败")
else:
    print("请求失败，状态码:", response.status_code)
