使用rwunderground包获取逐小时历史气象数据超时问题求助

Hey there! That timeout error usually pops up when the Weather Underground API takes longer than the default 10 seconds to respond, or your network connection is lagging. Let's work through some fixes step by step:

1. Extend the Request Timeout #

The rwunderground package relies on httr for HTTP requests, so you can pass a custom timeout configuration to give the API more time to send data back. Try setting a longer timeout (like 30 seconds) using httr::timeout():

library("rwunderground")
rwunderground::set_api_key("MY_API_KEY")
# Extend timeout to 30 seconds to avoid connection timeouts
history(set_location(zip_code = "90210"), "20170101", config = httr::timeout(30))

If 30 seconds still isn't enough, you can bump it up to 60 seconds or more depending on your network speed.

2. Validate Your API Key & Permissions #

Double-check that your Weather Underground API key is valid and has access to historical data endpoints. Free-tier keys often have rate limits or restricted access to certain data types—make sure your subscription plan allows fetching hourly historical weather data.

3. Check Network & Firewall Restrictions #

If you're on a corporate or restricted network, firewalls or proxies might be blocking the request to the Weather Underground API. Try testing the code on a different network (like your home Wi-Fi) to rule out this issue.

4. Batch Requests (For Future Multi-Day Queries) #

While you're only requesting a single day right now, if you plan to fetch data for multiple days later, splitting requests into smaller batches (one day at a time) can reduce the chance of timeouts compared to asking for a large date range all at once.
