$ mitmproxy

Error: mitmproxy requires Python 3.5 or above

Starting with version 1.0 released in 12/2016, mitmproxy no longer supports Python 2.

To install the latest version of mitmproxy using pip on Python 3, run:

    pip uninstall mitmproxy
    pip3 install mitmproxy

You can also use our standalone binaries that come with their own Python interpreter:

    http://docs.mitmproxy.org/en/stable/install.html

To get rid of this message and use the last version of mitmproxy that supports Python 2, run:

    pip install "mitmproxy==0.18.2"


Apologies for the inconvenience!

となるので、

$ sudo pip uninstall mitmproxy
$ sudo pip install "mitmproxy==0.18.2" --upgrade --ignore-installed six

と入れ直し。

$ mitmproxy

端末設定

iOSの場合、wifi設定から「HTTPプロキシ」の設定を行う。

サーバー：自分のマシンの IP アドレス
ポート番号：8080
認証：オフ

これで端末から通信すればコンソール上で内容確認が出来るっすー

コンソール操作は、

j,kで上下移動
enterで詳細
tabでRequest, Response, Detailのタブ切り替え
qで一覧へ戻る
Ctr+cで終了
