python - body = 'cmd=' + urllib_parse.quote_plus(unicode(verb).encode ('utf-8' )) 返回 "name ' unicode' 未定义”

Question

当我在 Python 3.4 上运行以下 python 代码时

# -*- coding: utf-8 -*-
import unittest, time, re
from selenium.selenium import selenium

class google(unittest.TestCase):
    def setUp(self):
        self.verificationErrors = []
        self.selenium = selenium("localhost", 4444, "*chrome", "https://www.google.com/")
        self.selenium.start()

    def test_google(self):
        sel = self.selenium
        sel.open("/?gws_rd=ssl")
        sel.type("id=gbqfq", "")
        sel.type("id=gbqfq", "test")

    def tearDown(self):
        self.selenium.stop()
        self.assertEqual([], self.verificationErrors)

if __name__ == "__main__":
    unittest.main()

我遇到错误名称'unicode'未定义:

======================================================================
ERROR: test_google (__main__.google)

Traceback (most recent call last):
  File "google.py", line 11, in setUp

NameError: name 'unicode' is not defined

怎么了？有办法解决吗？

Answer 1

正如它所说，unicode 不再是 3.x 中的内置 - 相反，str 类型描述了 Unicode 字符串。

您不应该收到此消息，因为它发生在 Selenium 代码中。这表明您没有正确安装 Selenium - 您拥有 2.x 代码，但试图从 3.x 中使用它。

快速检查文档表明 Selenium 支持 3.x - 但您需要卸载并重新安装它，并确保这次正确。
