使用click（）Webdriver Selenium函数Python时超时 [英] Timeout when using click() webdriver selenium function Python

问题描述

这是我的第一个Web抓取项目，我在Python上使用了Selenium Webdriver，以便在选择网站上的一些选项后动态生成一些csv文件（尽管我还没有）。

This is my first web scraping project and I'm using selenium webdriver with Python in order to dynamically generate some csv files after choosing a few options on a website (though I'm not there yet).

但是，当执行到达按钮click（）时，我面临着意外的超时。单击会执行，但会卡在其中，并且直到超时都不会继续执行。

However, I'm facing an unexpected timeout when the execution reaches a button click(). The click is performed but it gets stuck in there and does not continue the execution till the timeout.

有任何解决方法的线索吗？

Any clues on how to solve that?

谢谢！

from selenium import webdriver
from selenium.webdriver.support.ui import Select
import time


driver = webdriver.Firefox()
driver.get('http://www8.receita.fazenda.gov.br/SimplesNacional/Aplicacoes/ATBHE/estatisticasSinac.app/Default.aspx')
driver.find_element_by_id('ctl00_ctl00_Conteudo_AntesTabela_lnkOptantesPorCNAE').click()
Select(driver.find_element_by_id("ctl00_ctl00_Conteudo_AntesTabela_ddlColuna")).select_by_visible_text("Município")
filtro_uf =     driver.find_element_by_id('ctl00_ctl00_Conteudo_AntesTabela_btnFiltros')

for i in range (1, 28):
    filtro_uf.click()
    uf = Select(driver.find_element_by_id("ctl00_ctl00_Conteudo_AposTabela_ddlUf"))
    uf.options[i].click()
    time.sleep(2)
    driver.find_element_by_id('chkTodosMunicipios').click()
    time.sleep(2)
    driver.find_element_by_xpath("//*[contains(text(),'Ok')]").click()
    time.sleep(2)

# Here is where my code get stuck and gets a timeout
    driver.find_element_by_id('ctl00_ctl00_Conteudo_AntesTabela_btnExibir').click()

我得到的错误：

推荐答案

我找到了解决方法

显然，click（）函数会阻塞代码，直到页面完全加载为止。但是，由于某种原因，该页面会一直永久加载（无需加载其他任何内容），并保留我的代码，直到达到超时限制为止。

Apparently, the click() function blocks the code until the page is "completely" loaded. However, for some reason, the page keeps loading forever (without anything else to load) and it holds my code till it reaches the timeout limit.

而不是使用click，我已将其更改为键ENTER，并且页面仍然永久加载，但不再保存代码。

Instead of using click, I've changed it to key ENTER and the page still keeps loading forever but it doesn't hold the code anymore.

#FROM CLICK
driver.find_element_by_id('ctl00_ctl00_Conteudo_AntesTabela_btnExibir').click()

#TO SENDING ENTER (ue007)
driver.find_element_by_id('ctl00_ctl00_Conteudo_AntesTabela_btnExibir').send_keys(u'\ue007')
