Instagram ?__a=1接口失效及GraphQL查询数据问题（4月19日更新）

Hey folks, if you've been struggling to fetch a full list of Instagram user posts lately, you're not alone—Instagram's made some significant changes to their unofficial API in recent weeks, and here's the latest intel based on hands-on testing:

What's Broken Right Now #

• Pagination Methods: The previously reliable workflow using the endpoint https://www.instagram.com/{{username}}/?__a=1 with pagination via graphql.edge_owner_to_timeline_media.page_info.end_cursor is no longer functional. On top of that, the older max_id pagination parameter has been fully disabled by Instagram.
• Old Authentication: The ig_pr cookie that many developers relied on for authenticated requests has been blocked entirely—any requests using this cookie will now fail.

Current Working Approach (April 19 Update) #

The only viable way to fetch user post data right now is to use a valid, account-tied sessionid cookie in your request headers:

1. Grab the sessionid from an active, logged-in Instagram session (this cookie is specific to your account and needs to be fresh to avoid being flagged).
2. Include this sessionid in the Cookie header of your requests to Instagram's endpoints.
3. Note that while the basic ?__a=1 endpoint structure might still return partial data, pagination via the end cursor is no longer supported—you'll need to adapt to Instagram's updated GraphQL endpoint schema if you need to retrieve full post histories.

Heads up: Instagram actively enforces rate limits and blocks unofficial API usage, so even with a valid sessionid, avoid making excessive requests in a short window to prevent getting your account or IP flagged.
