1 判断编码

使用

response = requests.get(url)

获得网页内容后，用chardet判断网页编码方式

chardet.detect(response.content)

自己出现乱码的网页，response.encoding返回的结果是：ISO-8859-1。

而chardet.detect(response.content)返回的结果是：{'confidence': 0.99, 'encoding': 'GB2312'}。

2 将bytes转换为并写入文件

然后用该编码方式将response的内容转换为str类型

f.write(response.content.decode("GB2312","ignore"))

不加”ignore“参数容易报错，提示某些字符无法decode。

3 读取时指明编码方式

soup=BeautifulSoup(open("test.html"),"lxml",from_encoding="GB2312")

4 完整的编码示例

def saveUrl(url,fileName):
    url = "输入目标网址"
    fileName="希望保存的文件名称"
    response = requests.get(url)
    p("status_code:"+str(response.status_code))
    p("encoding:"+response.encoding)
    p("chardet result:")
    p(chardet.detect(response.content))
    f = open(fileName + ".html", 'w')
    f.write(response.content.decode(chardet.detect(response.content)["encoding"],"ignore"))
    f.close()

def mainF():
    #参数from_encoding="GB2312"来自p(chardet.detect(response.content))
    soup=BeautifulSoup(open("test.html"),"lxml",from_encoding="GB2312")
    soup = BeautifulSoup(open("test.html"), "lxml")
    p(soup.prettify())
    pass

saveUrl("","")
mainF()
