--------------------------------

### Run Chrome with Remote Debugging Enabled

Source: https://github.com/marty90/pychromedevtools/blob/master/README.md

Command to launch Google Chrome with remote debugging enabled on port 9222, allowing connections from any origin. This setup is essential for PyChromeDevTools to interact with the browser.

```Bash
google-chrome --remote-debugging-port=9222 --remote-allow-origins=*
```

### Measure Page Loading Time in Chrome

Source: https://github.com/marty90/pychromedevtools/blob/master/README.md

Demonstrates how to measure the time it takes for a web page to load using PyChromeDevTools. It enables Network and Page domains, navigates to a URL, and waits for the `Page.loadEventFired` event to determine the load completion time.

```Python
import PyChromeDevTools
import time

chrome = PyChromeDevTools.ChromeInterface()
chrome.Network.enable()
chrome.Page.enable()

start_time=time.time()
chrome.Page.navigate(url="http://www.google.com/")
chrome.wait_event("Page.loadEventFired", timeout=60)
end_time=time.time()

print ("Page Loading Time:", end_time-start_time)
```

--------------------------------

### Extract and Print All Object URLs from a Page

Source: https://github.com/marty90/pychromedevtools/blob/master/README.md

Shows how to capture and print all URLs of resources loaded by a web page using PyChromeDevTools. It navigates to a URL and then processes `Network.responseReceived` events from the message queue to extract and display each resource's URL.

```Python
import PyChromeDevTools

chrome = PyChromeDevTools.ChromeInterface()
chrome.Network.enable()
chrome.Page.enable()

chrome.Page.navigate(url="http://www.facebook.com")
event,messages=chrome.wait_event("Page.frameStoppedLoading", timeout=60)

for m in messages:
    if "method" in m and m["method"] == "Network.responseReceived":
        try:
            url=m["params"]["response"]["url"]
            print (url)
        except:
            pass
```

### Initialize ChromeInterface with Custom Host and Port

Source: https://github.com/marty90/pychromedevtools/blob/master/README.md

Initializes a ChromeInterface object, specifying a custom host and port for the Chrome remote debugging instance. This is useful when Chrome is not running on the default `localhost:9222` or on a different machine.

```Python
chrome = PyChromeDevTools.ChromeInterface(host="1.1.1.1",port=1234)
```

--------------------------------

### Initialize PyChromeDevTools ChromeInterface

Source: https://github.com/marty90/pychromedevtools/blob/master/README.md

Initializes a ChromeInterface object to connect to a running Chrome instance. By default, it attempts to connect to `localhost:9222`.

```Python
chrome = PyChromeDevTools.ChromeInterface()
```

--------------------------------

### Extract and Print All Cookies from a Loaded Page

Source: https://github.com/marty90/pychromedevtools/blob/master/README.md

Illustrates how to retrieve and display all cookies set by a web page using PyChromeDevTools. It navigates to a URL, waits for the page to stop loading, and then fetches network cookies using `Network.getCookies`.

```Python
import PyChromeDevTools
import time

chrome = PyChromeDevTools.ChromeInterface()
chrome.Network.enable()
chrome.Page.enable()

chrome.Page.navigate(url="http://www.nytimes.com/")
chrome.wait_event("Page.frameStoppedLoading", timeout=60)

#Wait last objects to load
time.sleep(5)

cookies,messages = chrome.Network.getCookies()
for cookie in cookies["result"]["cookies"]:
    print ("Cookie:")
    print ("\tDomain:", cookie["domain"])
    print ("\tKey:", cookie["name"])
    print ("\tValue:", cookie["value"])
    print ("\n")
```

--------------------------------

### Navigate Chrome Page using DevTools Protocol

Source: https://github.com/marty90/pychromedevtools/blob/master/README.md

Sends a `Page.navigate` command to the connected Chrome instance to load a specified URL. The function returns the command's interpreted JSON result and any messages received during the operation.

```Python
return_value, messages = chrome.Page.navigate(url="http://example.com/")
```

--------------------------------

### Wait for and Pop a Single Chrome DevTools Event Message

Source: https://github.com/marty90/pychromedevtools/blob/master/README.md

Blocks until a message is received from Chrome's event queue or a timeout occurs. It returns a single message, which is already interpreted as JSON. An optional `timeout` parameter can be specified.

```Python
message=chrome.wait_message()
```

--------------------------------

### Wait for a Specific Chrome DevTools Event

Source: https://github.com/marty90/pychromedevtools/blob/master/README.md

Blocks until an event with the specified `event_name` arrives or a timeout elapses. It returns the first matching event and all other events received before it. An optional `timeout` parameter can be configured.

```Python
matching_event,all_events=chrome.wait_event(event_name)
```

--------------------------------

### Retrieve All Currently Received Chrome DevTools Event Messages

Source: https://github.com/marty90/pychromedevtools/blob/master/README.md

Retrieves all messages currently in the event queue without blocking. This method is non-blocking and does not use a timeout, providing immediate access to accumulated events.

```Python
messages=chrome.pop_messages()
```
