mitmproxy修改接口返回
公司的软件库没有charles，也没有fiddler，也不让自己下载安装，只好自己写个代理修改接口返回了
在windows上安装和配置mitmproxy
-
安装mitmproxy包
pip install mitmproxy -
在命令行打 mitmweb 看是否能起起来一个8081的web网页
能打开下图2的网页则说明安装成功了，但是如果还没安装过证书的话，是还看不到任何请求的。
-
安装证书
windows下，安装完mitmproxy后，系统会自动下载好了证书，路径在 C:\Users\你的用户名.mitmproxy
3.1 双击mitmproxy-ca.p12,进入证书导入向导
3.2 直接下一步后，不填密码，再直接下一步
3.3 选择证书存储选【受信任的证书颁发机构】
3.4 点击完成,证书就导入到当前用户\计算机的根证书存储里面了
chrome开代理
-
打开chrome的设置 -- 搜索“代理” -- 点击“打开您的计算机代理设置”， 此时会打开系统的代理设置窗口
-
在手动设置代理打开代理，设置好端口为8080， 保存。如果是要代理本地某些网段的端口，如172.18..,要注意地址是否写入了禁用列表，必须从列表移除掉才能抓到包。
-
此时再打开 mitmweb ，可以看到已经能抓到http包了
代码
- 获取请求头和request_body
如下实例会打印请求头，并把请求body写入文件里
# 来自client的 HTTP 请求被成功完整读取(包括请求头以及body)
def request(self, flow: mitmproxy.http.HTTPFlow):
filter_host = "172.18.34.102"
url_path = "http://172.18.34.102:9005/xxx-api/containerType/query"
if (str(flow.request.host) == filter_host) and (str(flow.request.url) == url_path):
self.num += 1
ctx.log(u"处理第 %d 个请求" % self.num)
ctx.log(flow.request.headers) # 打印请求头
with open(r'./request_body.txt', 'a', encoding="utf-8") as file:
# file.write(str(flow.request.headers))
file.write(str(flow.request.get_text())) # 保存请求body
print("request_body 写入成功")
生成了一个request_body.txt的文件
- 修改repsonse
# 来自server的 HTTP 响应被成功完整读取
def response(self, flow: mitmproxy.http.HTTPFlow):
filter_host = "172.18.34.102"
url_path = "http://172.18.34.102:9005/xxx-api/base/getEnum"
if (str(flow.request.host) == filter_host) and (str(flow.request.url) == url_path):
res = json.loads(flow.response.get_text())
res['data']['commonEnum']['containerKind'] = {'CARTON': "纸箱", 'PLASTIC': "塑料", 'AAA':'哈哈哈'} # 修改接口返回
flow.response.set_text(json.dumps(res))
ctx.log('modified limitCount: {}'.format(res))
