如何发送含空格单词的GET请求？requests库请求异常疑问

Hey Bob, let's break down why your request isn't returning the content you expect—this is a common gotcha with how the requests library handles parameter values!

The Root Problem #

You set the query parameter to a list [brand, style], but Poshmark's search endpoint expects a single string where terms are joined by a + (like freepeople+top). When you pass a list to requests.get() for a parameter, the library will generate a URL with duplicate query parameters, like this:
https://poshmark.com/search?query=freepeople&query=top&type=listings&department=Women

That's not what the site's search system is looking for, so it returns unexpected results.

Corrected Code #

Here's how to fix it by joining your brand and style into a single string for the query parameter:

import requests

search = 'https://poshmark.com/search?'
brand = "freepeople"
style = "top"

# Join brand and style with a + to match the expected query format
queryParameters = {
    'query': f"{brand}+{style}",
    'type': 'listings',
    'department': 'Women'
}

# Optional: Add a User-Agent header to mimic a browser (some sites block default requests)
headers = {
    'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36'
}

response = requests.get(search, params=queryParameters, headers=headers)

# Verify the generated URL matches your target
print(response.url)

Quick Check #

After running this, print(response.url) should output exactly the URL you intended:
https://poshmark.com/search?query=freepeople+top&type=listings&department=Women

This should make the request match what you'd manually enter in a browser, so the response content should align with your expectations.
