使用mitmdump-map local功能修改雪球行情信息,报编码错误

环境:win10,mumu模拟器,python3.7,mitmdump 5.3.0,已配置好证书

问题描述:
1.执行
C:\Users\Cioffi>mitmdump -p 8999 -s F:\Users\Cioffi\PycharmProjects\selenium_hogwarts\mitm_proxy\maplocal_xueqiu.py,第一次刷新雪球APP数据可与json文件同步展示,当修改json文件中的信息,再次刷新APP的行情也,报错信息具体见log:

2.python代码如下:
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(
                200,  # (optional) status code
                f.read(),
                {"Content-Type": "application/json"}  # (optional) headers
            )

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

image

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。
