python 對任意文件(jpg,png,mp3,mp4)base64的編碼解碼

程序是事件驅動的，寫博客是什么驅動的？事件？ 時間？no，我承認我很懶，甚至不願意記錄總結。哪是什么驅動的？ 對！ 問題驅動的。遇到了問題解決了問題突然想起來搬到blog上，讓遇到相同問題的可以參考下。

問題所在

我用的Electronic WeChat，當朋友發送文字、圖片、甚至視頻的時候都可以打開（Audio無法收聽，因為電腦無外設音響/喇叭）。但發來的語音就扯蛋了，只能通過手機聽，甚至不能轉發。

但是發現可以通過開發者工具看到http語音文件的請求地址。

直接復制url在瀏覽器中打開沒有任何響應？難道是Referer與Cookie有判斷。果然！只有在登陸的瀏覽器中可以，不信你可以直接在瀏覽器中打開web微信嘗試操作，Electronic WeChat 只有一個tab。open link in new tab 其實就跳轉到瀏覽器了。然而開發者工具帶了一個騷操作，那就是“Copy Response”

copy response的數據為base64內容：

所以將base64轉換為對應的mp3格式不就可以播放了嗎？.......

 base64

Python的base64函數是內置函數，是一種用64個字符來表示任意二進制數據的方法。用記事本打開exe、jpg、pdf這些文件時，我們都會看到一大堆亂碼，因為二進制文件包含很多無法顯示和打印的字符，所以，如果要讓記事本這樣的文本處理軟件能處理二進制數據，就需要一個二進制到字符串的轉換方法。Base64是一種最常見的二進制編碼方法。

廖雪峰老師對base64的介紹

 

 base64對文件的編碼解碼

對文件的編碼就是讀取文件內容，encode為base64，對文件的解碼就是將base64字符串轉換為文件二進制。

• 編碼使用 base64.b64encode()
• 解碼使用 base64.b64decode()

讀取文件我們可以用with open as 也可以直接open，區別是with智能關閉文件，open要手動close文件。參考：https://www.cnblogs.com/gengcx/p/6713646.html

上代碼：

def ToBase64(file, txt):
    with open(file, 'rb') as fileObj:
        image_data = fileObj.read()
        base64_data = base64.b64encode(image_data)
        fout = open(txt, 'w')
        fout.write(base64_data.decode())
        fout.close()


def ToFile(txt, file):
    with open(txt, 'r') as fileObj:
        base64_data = fileObj.read()
        ori_image_data = base64.b64decode(base64_data)
        fout = open(file, 'wb')
        fout.write(ori_image_data)
        fout.close()

ToBase64("./desk.jpg",'desk_base64.txt')  # 文件轉換為base64
ToFile("./desk_base64.txt",'desk_cp_by_base64.jpg')  # base64編碼轉換為二進制文件

 

pyqt的GUI外衣

想轉換命令行就如上，但是操作不方便，可以給base64的代碼穿一個GUI外衣，使用pyqt方便的不得了！

這樣就可以把微信發送的語音文件保存下來了。猜猜上面那個 “data:audio/mp3;base64,..”說的什么玩意。
