我正在尝试使用 mechanize 将图片的 URL 提交到网站的图像搜索引擎。这是我的代码位。我选择的图像是从互联网上随机选择的。

r = br.open('http://stu.baidu.com/')
for f in br.forms():
    print f
br.select_form(nr=1)

br.form['objurl']='http://images2.fanpop.com/image/photos/13900000/Pretty-Dogs-in-Garden-dogs-13905929-1920-1200.jpg'
br.submit()
print br.submit

但是，这是我从终端响应中得到的。我不知道我哪里错了......

face2.py:13: UserWarning: gzip transfer encoding is experimental!
  br.set_handle_gzip(True)
<form2 POST http://stu.baidu.com/i?rt=0&rn=10&stt=0&ct=0&tn=baiduimage multipart/form-data

我似乎无法加载百度，但它可能与“用户警告：gzip 传输编码是实验性的”有关。或者，您可能需要对 GET 数据进行 urllib.urlencode。

一些例子： http: //pymotw.com/2/urllib/ http://kentsjohnson.com/kk/00010.html
