Python、BeautifulSoup、iMAP 和請求

Question

我正在編寫一個程序，它可以抓取電子郵件並從特定電子郵件（如 Newegg）中檢索鏈接。 我可以使用 iMAP 登錄並獲得 html 編碼，但是每當我在 BeautifulSoup 中實際找到 html 代碼時，href 不是實際鏈接。 下面的代碼是我正在使用的。

for part in email_message.walk():
    if part.get_content_maintype() == "multipart":
        continue
filename = part.get_filename()
    if not filename:
        ext = '.html'
        filename = 'msg-part-%08d%s' %(counter, ext)
        counter += 1
    content_type = part.get_content_type()
    print(content_type)
    if "html" in content_type:
        html_ = part.get_payload()
        soup = BeautifulSoup(html_, 'html.parser')
        print(soup.prettify())

我找到了我需要的特定“a”元素，但信息完全被打亂了。

<a 003e40bf801121da0c8026371fac2881d7ada96d0f3044bd52ea90c6f133482b7ac302="A6D66F63B93C9324A61A7BF6F53C6AD3B9FCE2E9722F2737F5C2BDEEC024FDB8BB1A8A=" 2='55);"' 255,="" 300px;="" 6035c14bccf6122e13d0c10420388428d9f6da5e55d8c39a946196846f58cb49754b4b="624023C5DA52531A16144B86B446AD159FC1B545111C71DA86A4B2BAB81E3BC6809F33=" a1c0a2d2231e3aa2c54f352a6ead95f6a0d3cad4f9d4610f9475ac"="" block;="" c41a281473fd50144612e9e4807a3c31920713f3fa05e6e851e830e5aaed502d2057db="5696E077EDBD8839ED7D1D9DFE6BCF861A354D0E6FB52F0818DB4C7971AB53C7F73CBB=" color:="" decoration:="" display:="" hre='f=3D"https://www.newegg.com/mr/DAC2DEFCF7F955FE4BCD7E3DF4926A74/D1F70B=' none;="" rgb(255,="" style='3D"text-=' target='3D"_blank"' width:="">

如果我用檢查元素提取它，這就是實際的 html 的樣子。

我究竟做錯了什么？ 為什么我的 href 實際上沒有作為 Newegg 鏈接出現？ 我可以從 BeautifulSoup 那里得到一點點並解擾它，但這不是我想要做的。

我需要能夠獲取鏈接才能在該鏈接上運行請求。

Answer 1

弄清楚了。 改變這個

html_ = part.get_payload()

對此

html_ = part.get_payload(decode=True)
