golang proper http2 request

问题

我想在Go语言中进行一个HTTP/2请求，但遇到了一些问题。如何在Go中进行正确的HTTP/2请求？

错误信息：Get "https://webhook.site/aae1e0ab-3e48-49c8-8cd0-526e12ee4077": http2: unexpected ALPN protocol ""; want "h2"（为什么？其他网站可以正常工作）

代码：

  1. t := &http2.Transport{}
  2. c := &http.Client{
  3.     Transport: t,
  4. }
  6. r, err := http.NewRequest("GET", "https://webhook.site/aae1e0ab-3e48-49c8-8cd0-526e12ee4077", nil)
  7. if err != nil {
  8.     fmt.Println(err)
  9. }
  10. r.Header.Set("User-Agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.2 Safari/605.1.15")
  11. r.Header.Set("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8")
  13. resp, err := c.Do(r)
  14. if err != nil {
  15.     fmt.Println(err)
  16. }
  17. defer resp.Body.Close()
  19. body, err := ioutil.ReadAll(resp.Body)
  20. if err != nil {
  21.     fmt.Println(err)
  22. }
  23. fmt.Println(string(body))

I want to make an http/2 request in go and got to a few issues there.
How to make proper http/2 requests in go?

Error: Get "https://webhook.site/aae1e0ab-3e48-49c8-8cd0-526e12ee4077": http2: unexpected ALPN protocol ""; want "h2" (Why? Other sites are working)

Code:

  1. t := &http2.Transport{}
  2. 	c := &http.Client{
  3. 		Transport: t,
  4. 	}
  7. 		r, err := http.NewRequest("GET", "https://webhook.site/aae1e0ab-3e48-49c8-8cd0-526e12ee4077", nil)
  8. 		if err != nil {
  9. 			fmt.Println(err)
  10. 		}
  11. 		r.Header.Set("User-Agent", "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/14.2 Safari/605.1.15")
  12. 		r.Header.Set("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8")
  14. 		resp, err := c.Do(r)

  24. 		fmt.Println(string(body))
  25.     ```

  33. 如前所述，该服务器不支持HTTP2：
  35. ~~~
  36. PS C:\> curl.exe -I --http2-prior-knowledge https://webhook.site
  37. curl: (16) HTTP2帧层出现错误
  38. ~~~
  40. 与支持HTTP2的服务器相比：
  42. ~~~
  43. PS C:\> curl.exe -I --http2-prior-knowledge https://example.com
  44. HTTP/2 200
  45. ~~~
  47. https://curl.se/docs/manpage.html#--http2-prior-knowledge

  52. As was mentioned, that server doesn&#39;t support HTTP2:
  54. ~~~
  55. PS C:\&gt; curl.exe -I --http2-prior-knowledge https://webhook.site
  56. curl: (16) Error in the HTTP2 framing layer
  57. ~~~
  59. Contrast with one that does:
