我收到了响应以及 header 响应和所有内容，但由于某种原因，正文是空的:
https://repl.it/repls/HastyAggravatingArchitect
package main
import (
"fmt"
"net/http"
"io/ioutil"
)
const url = "http://comicbookdb.com/search.php"
func main() {
request, err := http.NewRequest(http.MethodGet, url, nil)
if err != nil {
fmt.Println(err.Error())
return
}
q := request.URL.Query()
q.Add("form_search", "Captain America")
q.Add("form_searchtype", "Character")
// http://comicbookdb.com/search.php?form_search=captain%20america&form_searchtype=Character
request.URL.RawQuery = q.Encode()
client := http.DefaultClient
response, err := client.Do(request)
fmt.Println(response.Header.Get("Date"))
fmt.Println(response.StatusCode)
fmt.Println(response.Header.Get("Server"))
fmt.Println(response.Body)
r, err := ioutil.ReadAll(response.Body)
if err != nil {
fmt.Println(err.Error())
}
fmt.Println(string(r))
}
我在完整的 URL 中进行了评论，以便您可以自己查看并看到响应正文不应为空。
最佳答案
问题不在 go 程序中，您需要提供额外的 header ，在本例中它是 Cookie header :
package main
import (
"fmt"
"io/ioutil"
"net/http"
)
const url = "http://comicbookdb.com/search.php"
func main() {
request, err := http.NewRequest(http.MethodGet, url, nil)
if err != nil {
fmt.Println(err.Error())
return
}
// Here is requeired header
request.Header.Add("Cookie", "PHPSESSID=jmujtqjctuk1bv1g02ni88q9u5'")
q := request.URL.Query()
q.Add("form_search", "Captain America")
q.Add("form_searchtype", "Character")
request.URL.RawQuery = q.Encode()
client := &http.Client{}
response, err := client.Do(request)
if err != nil {
fmt.Println(err.Error())
return
}
fmt.Println(response.Header.Get("Date"))
fmt.Println(response.StatusCode)
fmt.Println(response.Header.Get("Server"))
fmt.Println(response.Body)
r, err := ioutil.ReadAll(response.Body)
if err != nil {
fmt.Println(err.Error())
}
fmt.Println(string(r))
}
输出:

关于go - Response.Body 返回 "empty"正文，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51238163/
