UnicodeDecodeError： 'ascii' codec 无法编码字符 u'\u2019'

Question

我不断遇到以下错误，似乎无法使.encode('ascii', errors='ignore')工作。

eqs = soup.find_all('div', {'style': 'margin:7px 5px 0px;vertical-align:top;text-align:center;display:inline-block;line-height:normal;width:120px;'})
for equipment in eqs:
    if '#b0c3d9' in str(equipment):
        f2.write(equipment.getText() + ', Commonn')
    if '#5e98d9' in str(equipment):
        f2.write(equipment.getText() + ', Uncommonn')
    if '#4b69ff' in str(equipment):
        f2.write(equipment.getText() + ', Raren')
    if '#8847ff' in str(equipment):
        f2.write(equipment.getText() + ', Mythicaln')
    if '#b28a33' in str(equipment):
        f2.write(equipment.getText() + ', Immortaln')
    if '#d32ce6' in str(equipment):
        f2.write(equipment.getText() + ', Legendaryn')
    if '#eb4b4b' in str(equipment):
        f2.write(equipment.getText() + ', Ancientn')
    if '#ade55c' in str(equipment):
        f2.write(equipment.getText() + ', Arcanan')

我尝试过：

f2.write(equipment.getText().encode('ascii', errors='ignore'))

和

f2.write(equipment.encode('ascii', errors='ignore').getText())

以及我为发布的其他一些事情。例如，通过Beautifuresoup以后会读取的文件运行，但这只是引发了不同的错误。再次感谢您的帮助。

我正在使用字符串从下面的HTML中解析出盒子阴影。我知道这可能不是最好的做法，但这是我想到的唯一途径。仍然是美丽的人。

<div style="margin:7px 5px 0px;vertical-align:top;text-align:center;display:inline-block;line-height:normal;width:120px;"><div style="margin-bottom: 5px;box-shadow:0px 0px 2px 4px #5e98d9;"><a href="/Pirate_Slayer%27s_Tricorn" title="Pirate Slayer's Tricorn"><img alt="Pirate Slayer's Tricorn" src="http://hydra-media.cursecdn.com/dota2.gamepedia.com/thumb/7/79/Pirate_Slayer%27s_Tricorn.png/120px-Pirate_Slayer%27s_Tricorn.png" width="120" height="80" srcset="http://hydra-media.cursecdn.com/dota2.gamepedia.com/thumb/7/79/Pirate_Slayer%27s_Tricorn.png/180px-Pirate_Slayer%27s_Tricorn.png 1.5x, http://hydra-media.cursecdn.com/dota2.gamepedia.com/thumb/7/79/Pirate_Slayer%27s_Tricorn.png/240px-Pirate_Slayer%27s_Tricorn.png 2x"></a></div>

Answer 1

您正在使用没有编解码器的str(equipment)；您将标签对象编码为ASCII。

不要使用str;将文本作为一个Unicode值。并使用映射和循环而不是许多if语句。

在这种情况下，style属性是您需要测试的全部：

types = {
    '#b0c3d9': 'Common',
    '#5e98d9': 'Uncommon',
    '#4b69ff':'Rare',
    '#8847ff': 'Mythical',
    '#b28a33': 'Immortal',
    '#d32ce6': 'Legendary',
    '#eb4b4b': 'Ancient',
    '#ade55c': 'Arcana'
}
for equipment in eqs:
    style = equipment.div.attrs.get('style', '')
    textcontent = equipment.getText().encode('utf8')
    for key in types:
        if key in style:
            f2.write('{}, {}'.format(textcontent, types[key])

但是，这些颜色代码很可能在equipment标签上的属性中；仅在标签值中查看，或使用.find()调用来缩小搜索范围。
