如何使用Python Requests修改casamundo搜索框输入值并提交搜索查询（不使用Selenium）

Got it, let's break down why your current approach isn't working and how to fix it.

Why Your data={'value': 'England'} Method Fails #

That readonly input with data-test="autocomplete-input" is just a UI display element—its value only shows the destination you've selected, not the actual parameter the server uses to process searches. When you send value: England via Requests, the server doesn't recognize it because the real search request uses entirely different parameters (often tied to internal destination IDs, not plain text).

Step 1: Find the Actual Search API #

First, you need to uncover the backend API that handles Casamundo's search requests:

1. Open your browser's DevTools (F12) and switch to the Network tab.
2. Go to the Casamundo search page, enter a destination (e.g., "France"), and click search.
3. Look for POST/GET requests labeled with terms like search, results, or query. Check the request's:
   • Request URL: The actual endpoint the search is sent to.
   • Form Data/Query Parameters: The key-value pairs the server expects (e.g., destinationId, checkIn, guests).
   • Headers: Critical details like User-Agent, Referer, and Cookie (many sites block requests without these).

Step 2: Simulate the API Request with Requests #

Once you have the correct endpoint and parameters, you can replicate the request directly. Here's a sample based on typical Casamundo API behavior:

import requests

# Create a session to persist cookies (helps avoid being blocked)
session = requests.Session()

# Copy headers from your browser's DevTools (adjust these to match your request)
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/118.0.0.0 Safari/537.36',
    'Referer': 'https://www.casamundo.com/search/',
    'Accept': 'application/json, text/plain, */*'
}

# Example payload (replace with parameters from your DevTools capture)
# Note: Many sites use destination IDs instead of plain text—get this from autocomplete API if needed
search_payload = {
    'destinationId': 'GBR-ENG',  # Example ID for England
    'destinationName': 'England',
    'checkIn': '2024-07-15',
    'checkOut': '2024-07-22',
    'adults': 2,
    'children': 0
}

# Send the request to the actual API endpoint
response = session.post(
    'https://www.casamundo.com/api/v2/search',  # Replace with your captured endpoint
    headers=headers,
    json=search_payload  # Use json= instead of data= if the request uses JSON format
)

# Process the response
if response.status_code == 200:
    results = response.json()
    print("Search results loaded successfully!")
    # Extract relevant data from results here
else:
    print(f"Request failed: Status code {response.status_code}")
    print(response.text)

Pro Tips #

• Get Destination IDs: If the API requires a destination ID (most do), look for an autocomplete API request when you type in the search box. It’ll return a list of destinations with their corresponding IDs.
• Update Headers: Always use real browser headers to avoid being flagged as a bot. You can copy these directly from DevTools' "Request Headers" section.
• Handle Cookies: Using a Session object ensures cookies are persisted, which helps maintain a valid session with the site.
