EdgeOne has a high threshold for use, and here we go again with an error: ERR_EMPTY_RESPONSE I asked the large model, but it couldn’t clarify the reason. Submitted a ticket, and then this issue was resolved. The ERR_EMPTY_RESPONSE error usually indicates that the client (such as a browser or network request tool) did not receive … Read more
Author | Frontend Craftsman Editor | Zhang Zhidong, Wang Wenjing HTTP/2 has significantly improved web performance compared to HTTP/1.1, requiring only an upgrade to this protocol to reduce many of the performance optimizations that were previously necessary. Of course, compatibility issues and how to gracefully downgrade are likely among the reasons it is not yet … Read more
In application development, HTTP/2 is a highly efficient network protocol that has garnered attention due to its features such as multiplexing and header compression. nghttp2 is an open-source project that provides rich functionality for implementing HTTP/2. As embedded platforms like the ESP32 evolve, applying the features of nghttp2 on these platforms has become a significant … Read more

Hello everyone, today I want to share a particularly useful Python library – httpx. Are you still using requests to send HTTP requests? Let me introduce this more modern and powerful new option! httpx not only supports the latest HTTP/2 protocol but also handles asynchronous requests, making it a great tool for web scraping and … Read more
Recently, while analyzing SSE technology, I briefly mentioned HTTP/2, as the HTTP/1.x protocol has long been considered an “antique”. Reasons for Upgrade Upgrading from HTTP/1.x to HTTP/2 can bring various performance improvements and optimizations: Multiplexing In HTTP/1.x, each TCP connection can only handle one request or response, leading to the so-called head-of-line blocking issue. In … Read more
In the internet age, network requests are like the daily “breath” of programmers. Whether it’s web scraping, API calls, or data interaction, we always need to deal with HTTP. Today, I want to introduce you to a super cool Python library—Httpx, which makes network requests so simple that you’ll scream! Getting to Know Httpx: A … Read more
