python& Selenium Click和"TypeError:字符串索引必须为整数". [英] Python & Selenium Click and "TypeError: string indices must be integers"

问题描述

我目前正在编写一段代码，并使用该纪录片进行了许多阅读，并看了许多示例，但是仍然无法修复我的错误.我正在使用Python和Selenium Webdriver.

I am currently working on a piece of code and have done many readings using the documentary and looked at many examples, but still I cannot fix my bug. I am using Python and Selenium Webdriver.

这是问题所在:我正在尝试从使用Javascript的HTML页面提取图像.一旦我使用了Selenium Webdriver，就会显示功能调用的结果(在firefox中)，但是我无法单击页面底部的数字进入第3或第4页.

Here's the problem: I am trying to extract an image from an HTML page that uses Javascript. The results from the function call are displayed (in firefox) once I use the selenium webdriver, but I cannot click on a number at the bottom of the page to go onto the 3rd or 4th page.

这是我遇到问题的HTML代码:

Here is the HTML code that I am having issues with:

<div class="pagebook" data-reactid=".1.0.2.0"><div style="display:none;" data-reactid=".1.0.2.0.0"></div><div class="active" data-reactid=".1.0.2.0.1:$0">1</div><div class="" data-reactid=".1.0.2.0.1:$1">2</div><div class="" data-reactid=".1.0.2.0.1:$2">3</div><div class="" data-reactid=".1.0.2.0.1:$3">4</div><div class="" data-reactid=".1.0.2.0.1:$4">5</div><div class="" dat<div class="next" style="margin-right:20px;" data-reactid=".1.0.2.0.$6">►</div></div>

我使用xpath功能进行了此调用:browser.find_element_by_xpath('//div[@data-reactid=".1.0.2.0.1:$2"]').click()

I did this call using xpath capability: browser.find_element_by_xpath('//div[@data-reactid=".1.0.2.0.1:$2"]').click()

我第一次这样做，它工作了几次，然后给了我一个错误，我再也无法使用它了.错误是:

The first time I did this it worked a few times and then it gave me an error and I could never use it again. The error was:

File "C:\Python27\Lib\site-packages\selenium-2.49.2-py2.7.egg\selenium\webdriver\remote\errorhandler.py", line 111, in check_response
    message = value["value"]["message"]
TypeError: string indices must be integers

这是我正在使用的代码:

Here is the code that I am using:

browser = webdriver.Firefox()
browser.implicitly_wait(5) #backup wait of 5 seconds just in case
browser.get(url2)
browser.find_element_by_xpath('//div[@data-reactid=".1.0.2.0.1:$2"]').click()

我在寻求帮助的地方

1. 错误
2. 使用其他点击功能

推荐答案

这是已知的，当前已打开的问题 a>在硒2.49中.解决方法是，将降级到2.48 :

This is a known, currently open, issue in selenium 2.49. As a workaround, downgrade to 2.48:

pip install selenium==2.48

---

我还将定位器改进为:

---

I would also improve the locator to:

//div[@class="pagebook"]/div[. = "2"]
