Python调用smallcase API调试：Thunder Client可用但脚本失败

Smallcase的/user/sc/drafts/save接口在Thunder Client中可正常调用，但在Python脚本中执行失败，尽管请求体和请求头与Thunder Client中完全一致：

• 已将终端打印的请求体复制到Thunder Client中验证，确认格式正确
• SC_CSRF_TOKEN是登录smallcase官网后从开发者工具的请求头中获取，反复核对过正确性

错误表现 #

1. 未使用json.dumps()处理请求体时，返回错误：

{'success': False, 'errors': ['Invalid token'], 'data': None}

2. 使用json.dumps()处理请求体后，返回结果：

{'data': 'Please mail us at tech@smallcase.com. Mistake is on our side!'}

预期成功响应 #

{
"success": true,
"errors": null,
"data": {
"did": ".......",
"scid": "......."
}
}

已尝试的解决方案 #

将生成的数据导出为JSON文件后再导入函数调用，问题仍未解决。

相关代码 #

import requests
import yfinance as yf
import json

# 替换为实际获取的SC_CSRF_TOKEN
SC_CSRF_TOKEN = "your-actual-token"
