I've successfully logged into a website and loaded a table that can then be downloaded as an .xls file. The issue I'm having is that an image has to be clicked to call the download. I haven't figured out how to post the correct data to fetch the .xls file.
Here is the website's HTML:
There is a link embedded in the website that points to //www.emlco.com/control/filedownload but when I try and get it, the page is empty.
Here is my code:
with requests.Session[] as z:
z.get["//www.emlco.com/control/j_security_check", stream=True]
p3 = z.post["//www.emlco.com/control/j_security_check",data=payload3]
z.get[link]
inventory_start = z.post[link, data={'newSearch':'true'}]
inventory_excel = z.post[link,data={'fileType':'mlInventory'}]
#inventory_excel = z.post['//www.emlco.com/control/filedownload',data={'fileType':'mlInventory'}]
inventory_excel = z.get['//www.emlco.com/control/filedownload', stream = True]
#output = open['MLCStock.xls', 'wb']
#output.write[inventory_excel.content]
#output.close[]
print[inventory_excel.url]
print[inventory_start.url]
print["Done"]
I apologize for the redundant comments. I was trying various combinations to see what would take.
Thanks in advance. I am quite new at Python.
I have this little website i want to fill in a form with the requests library. The problem is i cant get to the next site when filling the form data and hitting the button[Enter does not work].
The important thing is I can't do it via a clicking bot of some kind. This needs to be done so I can run in without graphics.
info = {'name':'JohnJohn',
'message':'XXX',
'sign':"XXX",
'step':'1'}
First three entries name, message, sign are the text areas and step is I think the button.
r = requests.get[url]
r = requests.post[url, data=info]
print[r.text]
The Form Data looks like this when i send a request via chrome manually:
- name:JohnJohn
- message:XXX
- sign:XXX
- step:1
The button element looks like this:
Wyślij
The next site if i do this manually has the same adres.
Hi there!
I was wondering how exactly I would go about using python's requests library to click on buttons on a webpage. After I click on a button on a webpage I want to be able to access the page that I am redirected to.
As an example, if I wanted to access r/learnpython's homepage and then click the "Create Post" button to have the webpage redirect me to the page that lets me create a post, how would I use requests to do that?
r = requests.get['//www.reddit.com/r/learnpython/new/']
Keep in mine that I do not want to go to the URL "//www.reddit.com/r/learnpython/submit" directly. I want to be able to actively press the "Create Post" button in this example. I also don't want to use selenium or any other solution that requires me to have a the browser's GUI open.
I know this is basic but I can't for the life of me find a post that gives me a clear answer to this question. Thanks for your time!!!
TL;DR: Don't think that this functionality is available yet with requests-HTML, as the script argument is used to scrape static HTML only [and not to run js on a dynamic page]. Seems like Selenium is the only option [if button click causes existing data on the page to change, instead of opening a new page, and the method for the button click is located in the backend]?
When I try to put js in the script I get a puppeteer error.
For example, I have the following code:
script = """
[] => {
let button = document.getElementsByClassName["course-title"][0]
button.click[]
}
"""
r.html.render[sleep=5, timeout=10000, script=script, keep_page=True]
and I get the error:
pyppeteer.errors.ElementHandleError: Evaluation failed: TypeError: Cannot read property
'click' of undefined
at pyppeteer_evaluation_script:4:20
I thought that maybe the page content wasn't rendering properly, so I wrote [this was right above where script was declared]
with open['response.txt', 'w', encoding='utf-8'] as f:
f.write[r.text]
to get the content of the HTML, and the element did exist on the page.
Similar error when trying to use jQuery [website has jQuery enabled]
Code:
script = """
[] => {
$[document].ready[function[] {
$[".course-title"][0].click[];
}]
}
"""
response = r.html.render[sleep=5, timeout=10000, script=script, keep_page=True]
Error:
response is None
So then I wanted to check if js was even working and wrote:
script = """
[] => {
return 1+1;
}
"""
response = r.html.render[sleep=5, timeout=10000, script=script, keep_page=True]
print[response]
Output:
2
This means that the role of passing a
script to the render function is not to run the script on the page, but rather to run a script to scrape the static HTML content of the page. Otherwise, the response would be an object [requests.Response[] object with the attributes .text and methods .json[], etc.]. Furthermore, in the case where a button click edits content on the page, and the method for the click is in the backend [I mean this is the only reason you would have to click a button in the first place, otherwise just look at the
URL endpoint, or what the method for the click does], not being able to get the HTML response is useless?
This matches up with the documentation for requests-HTML where the only time they mention render[script=script] is under the line "You can also render JavaScript pages without Requests:", and in this section, the js is simply run on a HTML string [and this js is just for getting information in the HTML], and the return of the render is just the return of the js code that was in script.
How do you simulate a button click in Python?
1 Answer.
Pressed F12 key to enter it and selected the Network Tab..
Clicked the "Display more examples" button..
Found the last request ["bst-query-service"].
Right-clicked it and selected Copy > Copy as cURL [cmd].
How do you press a button on a website using python?
We can find the button on the web page by using methods like find_element_by_class_name[], find_element_by_name[], find_element_by_id[] etc, then after finding the button/element we can click on it using click[] method. This will click on the button and a popup will be shown.
