chromote's Issues

KeyError: 'webSocketDebuggerUrl'

Hi, sometimes this exception is yield:

Traceback (most recent call last):
  File "D:\sources\personal\www\www.todotrucos.info\posts\foo_post.py", line 33, in <module>
    wpp.run(filename=__file__, post_content=POST, tags=[], post_status="draft")
  File "D:\sources\personal\python\framework\web\wp_lib.py", line 280, in run
    print chrome.tabs
  File "d:\virtual_envs\py2710\lib\site-packages\chromote\__init__.py", line 122, in tabs
    return tuple(self._get_tabs())
  File "d:\virtual_envs\py2710\lib\site-packages\chromote\__init__.py", line 106, in _get_tabs
    yield ChromeTab(tab['title'], tab['url'], tab['webSocketDebuggerUrl'])
KeyError: 'webSocketDebuggerUrl'

And the code yielding that exception is very basic

chrome = Chromote()
print chrome.tabs

As i said, it happens sometimes but i don't know, any clue why?

Regards

Chrome wont start with debugging

I couldn't get Chrome to start with the remote debugging port enabled. I finally realized that you have to kill any chrome processes on Windows first, before you can start Chrome with the remote debugging port enabled. I thought others may benefit from this info.

How do we get the contents of the page from the tab?

from chromote import Chromote
chrome = Chromote()

chrome.tabs[0].set_url('http://www.nytimes.com')
    print(chrome.tabs[0])

"The New York Times - Breaking News, World News & Multimedia - https://www.nytimes.com/"

How we we get the contents of the page?

Add new version number to current code

Could you please add a new version number to the current code? Currently, pip install chromote installs version 0.3.0, which is missing the add_tab, close_tab functionality implemented in commit #13.

Using chromote for multiple Chrome processes with different debugger ports?

Is it possible to use Chromote for multiple Chrome processes with different debugger ports? For example, if I open two new Chrome windows with debugger port 9222 and port 9223, can I create two Chromote instances in a single parent process and connect them to their respective browser processes?

The reason for this is that I want to use Chromote as a load testing tool for a web application, where a number of clients open up browsers and remote control them simultaneously.

in `_send`, should `Runtime.evaluate` take `"returnByValue": False`?

This is perhaps more of a question than an issue, but in my project, I need to add "returnByValue": False, at around line 72 in __init__.py:

(note, I'm adding line breaks only to make it easier to read)

def evaluate(self, javascript):
    """
    Evaluate JavaScript on the page
    """
    return self._send(
        {"method": "Runtime.evaluate", 
         "params": {"expression": javascript, 
            "returnByValue": False}})        # <---- This bit

Without this, I don't get back the full string contents of returned data, e.g. the results of Array maps and so on. I'm happy to make a PR to make this a setting (e.g. an extra param on evaluate, with default set to True), but just wanted to find out your thoughts?

Documentation?

Is the full documentation available anywhere for the API?

I am looking for a way to open multiple tabs and cycle between them, preferably without reloading the tab each time.

how to make mouseclicks on ajax pages?

Post request use chromote

Hi, thanks for your job!
By using chromote, i can set a url to remote Chrome(in docker container) and return a html code, but i can't sent a post request to the chrome, do you have any idea? Thanks again!

example: How can i get a logged-in page when i send a login url to remote headless Chrome?

LICENSE file

First of all, thanks for a nice software!

Could you add LICENSE file?
The following page might help for choosing a license.

Thanks!

cannot use chrome.tabs

Hey, thanks for making this repo. I tried to run but I'm running into an issue:

>>> from chromote import Chromote
>>> chrome = Chromote()
>>> chrome
Chromote(host="localhost", port=9222)
>>> print chrome

According to readme, I should see the following:

[Chromote(tabs=1)]

But instead, I see this error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.6/site-packages/chromote/__init__.py", line 156, in __str__

    return len(self.tabs)

    return tuple(self._get_tabs())

    for tab in res.json():

    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/usr/local/lib/python3.6/json/decoder.py", line 357, in raw_decode
    raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)

Tried this in python 2.7 and got the same result as well.

Any ideas????

Thanks!
