在 Python 中使用 Selenium 和 PhantomJS 时出现异常错误

Question

我正在尝试填写 these page 的表格，我检查了 HTML 代码，并且我正在寻找的表格在那里，但是当我运行我的代码时，我遇到了一个我在 selenium 中从未见过的错误。

我在带有 Selenium 的 Python 3.6.1 中使用 PhantomJS 2.1.1。

我想填写这些表格。

<input type="text" name="Dt_Ref" value="31/08/2017" maxlength="10" size="10" class="form_data" onBlur="formatCamp(this, 'date');javascript:if(REUNE.Dt_Ref.value!=REUNE.Dt_RefAnt.value){REUNE.target='_self';REUNE.action='reune.asp';REUNE.submit()};" onKeyPress="return(validaConteudo(event, this, 'date'))" onKeyUp="saltaCampo(event, this, 'date',8)" onFocus="removeCaracs(this, 'date')">  <a style="cursor:hand; cursor:pointer;" onclick="openCalendar(document.REUNE.elements['Dt_Ref']);return false;">

我的代码是：

from selenium import webdriver


url = 'http://www.anbima.com.br/reune/reune.asp'
path_phantom = 'C:\\Users\\TBMEPYG\\AppData\\Local\\Continuum\\Anaconda3\\Lib\\site-packages\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe'

#Processing

driver = webdriver.PhantomJS(executable_path= path_phantom)
driver.get(url)
name = driver.find_element_by_name("Dt_Ref")
driver.quit()

我得到了这个错误：

Traceback (most recent call last):
  File "C:\Users\TBMEPYG\Desktop\beta_anbima.py", line 11, in <module>
    name = driver.find_element_by_name("Dt_Ref")

这是我的代码的第一步。我在银行代理下，这可能是问题所在。当我从我的 Chrome 访问时，该页面工作正常。 当我尝试在 this site 中使用相同的代码（更改 url 和元素名称）时，它工作正常。

谢谢大家。

这是 PhantomJS 的问题/错误。

我建议您使用 Chrome 或 docker 镜像作为 selenium/standalone-chrome

如果您查看https://github.com/ariya/phantomjs/issues，则有1923 未解决的问题，这是不言而喻的。

你甚至不能查询

driver.find_elements_by_xpath("//*")

你会得到错误

NoSuchElementException: Message: {"request":{"headers":{"Accept":"application/json","Accept-Encoding":"identity","Connection":"close","Content-Length":"87","Content-Type":"application/json;charset=UTF-8","Host":"127.0.0.1:53425","User-Agent":"Python http auth"},"httpVersion":"1.1","method":"POST","post":"{\"using\": \"xpath\", \"value\": \"//*\", \"sessionId\": \"eb09e680-8e72-11e7-8b72-d1137b47fa59\"}","url":"/elements","urlParsed":{"anchor":"","query":"","file":"elements","directory":"/","path":"/elements","relative":"/elements","port":"","host":"","password":"","user":"","userInfo":"","authority":"","protocol":"","source":"/elements","queryKey":{},"chunks":["elements"]},"urlOriginal":"/session/eb09e680-8e72-11e7-8b72-d1137b47fa59/elements"}}

所以打开一个错误并计算1924，但我真的怀疑你会得到多少帮助
