from mitmproxy import http
# 报错：待debug，数据未同步更新
# request 方法名不能修改，当有请求来的时候，就会回调request方法
# flow：请求接口中的数据
def request(flow: http.HTTPFlow):
# 发起请求，获取当前接口的url，判断是否等于指定的路径
if "quote.json" in flow.request.pretty_url:
# 打开本地的数据文件
with open(r"G:\hogwarts_workspace\apitest\map_local\quote2.json","r",encoding="utf-8") as f:
# 创造一个response
flow.response = http.HTTPResponse.make(

同学，你这个报错信息好像没有传好，主要还是要看log是什么原因
已经重新粘贴了log的内容，麻烦帮忙看下，多谢啦
这个解码问题不确定是不是win系统的问题，看看这个帖子能不能帮到你：
我好像看到你哪里问题了，你的这行代码：
with open(r"G:\hogwarts_workspace\apitest\map_local\quote2.json","r",encoding="utf-8") as f:
把“with open(r"")”里面那个r去掉吧，看看，这里应该是直接贴你的json文件绝对路径就行
此处需要防止字符转义，路径中包含\a
你可以把你路径里那个 apitest换一个名字，就不用转义了，这是最快解决问题的办法。
如果你要坚持这个路径，那就还是要看看这句里有没有别的问题，总之报错就是出在这个处理上哈
已修改路径，报错依然存在
用来转义的r已经去掉了对吗
是的
把要判断的语句换成这个试试：
if "https://stock.xueqiu.com/v5/stock/batch/quote.json?_t=" in flow.request.pretty_url:
报错依然存在
没辙了，看不出来什么问题，那看看我之前发那个链接尝试别的解决方法哈
你的文件内容是gbk吧，然后你尝试用utf8解析？
我也是报这个错误，然后我单独执行with open那个命令不报错，执行windows命令就报这个错误
json的编码格式也是utf-8的
我之前也遇到类似的问题，实际是安装的mimtproxy版本为5.3.0导致的，你卸载重装mimtproxy为5.2.0版本试试
问题已解决，感谢啊。果然5.2版本用着明显比5.3顺畅，之前使用5.3版本，加载修改后的json或python文件时会明显卡顿一会儿。
