机械化python单击按钮(python 机械)

我有一个带有<input type="button" name="submit" />按钮的表单,希望能够单击它。

我已经尝试过,mech.form.click("submit")但是会出现以下错误:

ControlNotFoundError: no control matching kind ''clickable'', id ''submit''

mech.submit() 也不起作用,因为它的类型是按钮并且不提交。

有任何想法吗?谢谢。

单击type="button"纯HTML 的形式什么都不做。为了执行任何操作,必须包含 javascript

并且mechanize不运行 javascript

因此,您的选择是:

  • 自己阅读JavaScript并模拟mechanize其效果
  • 使用spidermonkey运行JavaScript代码

我会做第一个,因为使用起来spidermonkey似乎很困难,可能不值得。

ElementNotVisibleException:消息:尝试通过Selenium和Python单击按钮时,元素不可交互错误

ElementNotVisibleException:消息:尝试通过Selenium和Python单击按钮时,元素不可交互错误

我有一个包含源代码的页面,如下面的代码。在执行操作后,在其中显示“撤消”和“关闭”按钮。我试图单击“关闭”按钮。我已经尝试了下面的所有三个代码块,但都无法正常工作。有人可以指出我做错了什么,还是建议其他尝试?

html来源:

<div><div><i></i><div>Your stuff is going to <span>place</span> is on its way.</div><div><button> Undo</button></div><div><button> Close</button></div></div></div>

与文本的元素 关闭 是一个动态的元素,以便找到你要引起元素 WebDriverWait元素是可点击 ,你既可以使用以下方法解决:

  • 使用CSS_SELECTOR

    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.action-bar button.c-button.c-button--blue"))).click()
  • 使用XPATH

    WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[contains(@class, ''action-bar'')]//button[@c-button c-button--blue'' and normalize-space()=''Close'']"))).click()
  • 注意 :您必须添加以下导入:

        from selenium.webdriver.support.ui import WebDriverWait    from selenium.webdriver.common.by import By    from selenium.webdriver.support import expected_conditions as EC

php-Python:使用机械化将数据提交到表单后,提取.csv结果

php-Python:使用机械化将数据提交到表单后,提取.csv结果

我是第一次使用Python从网络上提取数据.多亏了其他一些帖子以及webpage,我才知道如何使用机械化模块将数据提交到表单.

现在,我坚持寻找如何提取结果.提交表单时会有很多不同的结果,但是如果我可以访问csv文件,那将是完美的.我假设您必须使用re模块,但是如何通过Python下载结果呢?

运行作业后,csv文件位于此处:摘要=>结果=>下载重链表(您只需单击“加载示例”即可查看该网页的工作方式).

import re
import mechanize

br = mechanize.browser()
br.set_handle_robots(False)   # ignore robots
br.set_handle_refresh(False)  # can sometimes hang without this

url = 'http://circe.med.uniroma1.it/proABC/index.PHP'
response = br.open(url)

br.form = list(br.forms())[1]

# Controls can be found by name
control1 = br.form.find_control("light")

# Text controls can be set as a string
br["light"] = "DIQMTQSPASLSASVGETVTITCRASGNIHNYLAWYQQKQGKSPQLLVYYTTTLADGVPSRFSGSGSGTQYSLKINSLQPEDFGSYYCQHFWSTPRTFGGGTKLEIKRADAAPTVSIFPPSSEQLTSGGASVVCFLNNFYPKDINVKWKIDGSERQNGVLNSWTDQDSKDSTYSMsstLTLTKDEYERHNSYTCEATHKTSTSPIVKSFNRNEC"

# To submit form
response = br.submit()
content = response.read()
# print content

result = re.findall(r"Prob_Heavy.csv", content)
print result

打印内容时,我感兴趣的行如下所示:

<h2>Results</h2><br>
Predictions for Heavy Chain:
<a href='u17003I9f1/Prob_Heavy.csv'>Download Heavy Chain Table</a><br>
Predictions for Light Chain:
<a href='u17003I9f1/Prob_Light.csv'>Download Light Chain Table</a><br>

因此,问题是:如何下载/访问href =’u17003I9f1 / Prob_Heavy.csv’?

解决方法:

这是一个使用BeautifulSoup的快速且肮脏的示例,它请求避免使用正则表达式解析HTML. sudo pip install bs4(如果您已安装pip但尚未安装BeautifulSoup).

import re
import mechanize
from bs4 import BeautifulSoup as bs
import requests
import time


br = mechanize.browser()
br.set_handle_robots(False)   # ignore robots
br.set_handle_refresh(False)  # can sometimes hang without this

url_base = "http://circe.med.uniroma1.it/proABC/"
url_index = url_base + "index.PHP"

response = br.open(url_index)

br.form = list(br.forms())[1]

# Controls can be found by name
control1 = br.form.find_control("light")

# Text controls can be set as a string
br["light"] = "DIQMTQSPASLSASVGETVTITCRASGNIHNYLAWYQQKQGKSPQLLVYYTTTLADGVPSRFSGSGSGTQYSLKINSLQPEDFGSYYCQHFWSTPRTFGGGTKLEIKRADAAPTVSIFPPSSEQLTSGGASVVCFLNNFYPKDINVKWKIDGSERQNGVLNSWTDQDSKDSTYSMsstLTLTKDEYERHNSYTCEATHKTSTSPIVKSFNRNEC" 
br["heavy"] = "QVQLKESGPGLVAPSQSLSITCTVSGFSLTGYGVNWVRQPPGKGLEWLGMIWGDGNTDYNSALKSRLSISKDNSKSQVFLKMNSLHTDDTARYYCARERDYRLDYWGQGTTLTVSSASTTPPSVFPLAPGSAAQTNSMVTLGCLVKGYFPEPVTVTWNSGSLSSGVHTFPAVLQSDLYTLSSSVTVPsspRPSETVTCNVahpAsstKVDKKIVPRDC"

# To submit form
response = br.submit()
content = response.read()
# print content

soup = bs(content)
urls_csv = [x.get("href") for x in soup.findAll("a") if ".csv" in x.get("href")]
for file_path in urls_csv:
    status_code = 404
    retries = 0
    url_csv = url_base + file_path
    file_name = url_csv.split("/")[-1]
    while status_code == 404 and retries < 10:
        print "{} not ready yet".format(file_name)
        req = requests.get(url_csv )
        status_code = req.status_code
        time.sleep(5)
    print "{} ready. Saving.".format(file_name)
    with open(file_name, "wb") as f:
        f.write(req.content)

在REPL中运行脚本:

Prob_Heavy.csv not ready yet
Prob_Heavy.csv not ready yet
Prob_Heavy.csv not ready yet
Prob_Heavy.csv ready. Saving.
Prob_Light.csv not ready yet
Prob_Light.csv ready. Saving.

python selenium单击按钮

python selenium单击按钮

我是python selenium的新手,我尝试单击具有以下html结构的按钮:

<div>    <divonclick="submitForm(''mTF'')">        <inputtype="button"></input>        <div></div>        <span>           Search        </span>    </div>    <divonclick="submitForm(''rMTF'')">        <inputtype="button"></input>        <span>              Reset        </span>   </div></div>

我希望能够同时单击上方的SearchReset按钮(显然是单独单击)。

我尝试了几件事,例如:

driver.find_element_by_css_selector(''.button .c_button .s_button'').click()

要么,

driver.find_element_by_name(''s_image'').click()

要么,

driver.find_element_by_class_name(''s_image'').click()

但是,我似乎总是以结尾NoSuchElementException,例如:

selenium.common.exceptions.NoSuchElementException: Message: u''Unable to locate element: {"method":"name","selector":"s_image"}'' ;

我想知道是否可以以某种方式使用HTML的onclick属性来进行selenium单击?

任何能将我指向正确方向的想法都很棒。谢谢。

对于python,请使用

from selenium.webdriver import ActionChains

ActionChains(browser).click(element).perform()

Python selenium无法单击按钮弹出窗口

Python selenium无法单击按钮弹出窗口

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

import time
driver = webdriver.Chrome()

driver.get('https://developers.google.com/gmail/api/quickstart/python')


elem=driver.find_element_by_xpath(
    "//a[@]")

driver.execute_script("arguments[0].scrollIntoView({block: 'center'})",elem)

elem.click()

wait = WebDriverWait(driver,50)

wait.until(EC.frame_to_be_available_and_switch_to_it(
(By.CSS_SELECTOR,'.devsite-henhouse-dialog iframe')))

wait.until(EC.presence_of_element_located(
    (By.XPATH,"//button[@]"))).click()

它在 iframe 内,将其切换到它并使用 webdriver 等待
