Unexpected EOF while trying to send a request from a parsed Raw HTTP request

问题

我正在使用golang解析原始的HTTP请求，然后发送一个请求到URL并打印输出。

代码：

  1. stra := `GET / HTTP/1.1
  2. Host: google.com
  3. Upgrade-Insecure-Requests: 1
  4. User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.61 Safari/537.36
  5. Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9
  6. Accept-Encoding: gzip, deflate
  7. Accept-Language: en-US,en;q=0.9
  8. Connection: close`
  9. r, err := http.ReadRequest(bufio.NewReader(strings.NewReader(stra)))
  10. if err != nil {
  11.     fmt.Println(err.Error())
  12.     os.Exit(1)
  13. }
  14. u, err := url.Parse("https://" + r.Host + r.URL.String())
  15. if err != nil {
  16.     panic(err)
  17. }
  18. req.URL = u
  19. transport := http.Transport{}
  20. transport.TLSClientConfig = &tls.Config{InsecureSkipVerify: true}
  21. client := &http.Client{Transport: &transport}
  22. resp, err := client.Do(req)

错误：

  1. unexpected EOF

请帮忙看看。

I'm using golang to parse a raw HTTP request and then send a request to the URL and print the output.

Code:

  1. stra := `GET / HTTP/1.1
  2. Host: google.com
  3. Upgrade-Insecure-Requests: 1
  4. User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.61 Safari/537.36
  5. Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9
  6. Accept-Encoding: gzip, deflate
  7. Accept-Language: en-US,en;q=0.9
  8. Connection: close`
  9. 	r, err := http.ReadRequest(bufio.NewReader(strings.NewReader(stra)))
  10. 	if err != nil {
  11. 		fmt.Println(err.Error())
  12. 		os.Exit(1)
  13. 	}
  14. 	u, err := url.Parse("https://" + r.Host + r.URL.String())
  15. 	if err != nil {
  16. 		panic(err)
  17. 	}
  18. 	req.URL = u
  19. 	transport := http.Transport{}
  20. 	transport.TLSClientConfig = &tls.Config{InsecureSkipVerify: true}
  21. 	client := &http.Client{Transport: &transport}
  22. 	resp, err := client.Do(req)

Error:

  1. unexpected EOF

http头部必须以\r\n\r\n结尾，但是对于http.ReadRequest来说，似乎\n也可以。下面的代码确实有效。

  1. package main
  3. import (
  4. 	"bufio"
  5. 	"fmt"
  6. 	"net/http"
  7. 	"os"
  8. 	"strings"
  9. )
  11. func main() {
  12. 	stra := `GET / HTTP/1.1
  13. Host: google.com
  14. Upgrade-Insecure-Requests: 1
  15. User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.61 Safari/537.36
  16. Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9
  17. Accept-Encoding: gzip, deflate
  18. Accept-Language: en-US,en;q=0.9
  19. Connection: close
  21. `
  22. 	req, err := http.ReadRequest(bufio.NewReader(strings.NewReader(stra)))
  23. 	if err != nil {
  24. 		fmt.Println(err.Error())
  25. 		os.Exit(1)
  26. 	}
  27. 	fmt.Println(req)
  28. }
英文:

http header must ends with \r\n\r\n, but it seems that \n is ok for http.ReadRequest? the code below really works.

  1. package main
  3. import (
  4. 	"bufio"
  5. 	"fmt"
  6. 	"net/http"
  7. 	"os"
  8. 	"strings"
  9. )
  11. func main() {
  12. 	stra := `GET / HTTP/1.1
  13. Host: google.com
  14. Upgrade-Insecure-Requests: 1
  15. User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.61 Safari/537.36
  16. Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9
  17. Accept-Encoding: gzip, deflate
  18. Accept-Language: en-US,en;q=0.9
  19. Connection: close
  21. `
  22. 	req, err := http.ReadRequest(bufio.NewReader(strings.NewReader(stra)))
  23. 	if err != nil {
  24. 		fmt.Println(err.Error())
  25. 		os.Exit(1)
  26. 	}
  27. 	fmt.Println(req)
  28. }
