How to return gzip response for golang gin framework
问题
我正在尝试使用Golang框架gin返回gzip响应。
他们在这里提供了一个示例:
https://github.com/gin-gonic/contrib/blob/master/gzip/example/example.go
package main
import (
"fmt"
"github.com/gin-gonic/contrib/gzip"
"github.com/gin-gonic/gin"
"time"
)
func main() {
r := gin.Default()
r.Use(gzip.Gzip(gzip.DefaultCompression))
r.GET("/ping", func(c *gin.Context) {
c.String(200, "pong "+fmt.Sprint(time.Now().Unix()))
})
// Listen and Server in 0.0.0.0:8080
r.Run(":8080")
}
当我使用这个示例时,它没有返回gzip内容。
使用上面的代码,我从curl命令得到以下输出:
curl -v -H "Accept-Encoding: gzip" 'http://localhost:8080/ping'
Trying ::1...
Connected to localhost (::1) port 8080 (#0) GET /ping HTTP/1.1
Host: localhost:8080
User-Agent: curl/7.43.0
Accept: /
Accept-Encoding: gzip
< HTTP/1.1 200 OK
< Content-Encoding: gzip
< Content-Type: text/plain; charset=utf-8
< Vary: Accept-Encoding
< Date: Mon, 18 Jul 2016 17:20:56 GMT
< Content-Length: 38
<
Connection #0 to host localhost left intact pong 1468862456?n????
注意到内容没有被gzip压缩,并且添加了额外的乱码字符 "?n????"。
到目前为止,我无法弄清楚如何使其返回gzip。我认为示例代码中有一个错误,但我很难找出来。
提前谢谢你。

I'm trying to return a gzip response using the golang framework gin.
They provide an example here:
https://github.com/gin-gonic/contrib/blob/master/gzip/example/example.go
package main
import (
"fmt"
"github.com/gin-gonic/contrib/gzip"
"github.com/gin-gonic/gin"
"time"
)
func main() {
r := gin.Default()
r.Use(gzip.Gzip(gzip.DefaultCompression))
r.GET("/ping", func(c *gin.Context) {
c.String(200, "pong "+fmt.Sprint(time.Now().Unix()))
})
// Listen and Server in 0.0.0.0:8080
r.Run(":8080")
}
When I use this example its not returning gzipped content.
With the code above I get the following output from curl
curl -v -H "Accept-Encoding: gzip" 'http://localhost:8080/ping'
Trying ::1...
Connected to localhost (::1) port 8080 (#0) GET /ping HTTP/1.1 Host: localhost:8080 User-Agent: curl/7.43.0 Accept: / Accept-Encoding: gzip
< HTTP/1.1 200 OK
< Content-Encoding: gzip
< Content-Type: text/plain; charset=utf-8
< Vary: Accept-Encoding
< Date: Mon, 18 Jul 2016 17:20:56 GMT
< Content-Length: 38
<
Connection #0 to host localhost left intact pong 1468862456?n????
Notice the content is not gzipped and there are extra junk characters added on.
"?n????"
So far I can't figure out how to get it to return gzip. I think there is a mistake in the example code but I'm having trouble figuring it out.
Thank you in advance.

有人遇到了gzip的问题。他们的拉取请求解决了我的问题。这是gin框架gzip包中的一个错误。
在contrib/gzip/gzip.go文件中缺少了这个方法:
func (g *gzipWriter) WriteString(s string) (n int, err error) {
return g.writer.Write([]byte(s))
}
原始问题链接,包括拉取请求:
https://github.com/gin-gonic/contrib/pull/59
一旦项目所有者接受了这个拉取请求,这个问题就会被解决。
英文:
Someone else had an issue with gzip. Their pull request resolved this problem for me. It's a bug in the gzip package for gin framework.
This method was missing from contrib/gzip/gzip.go
func (g *gzipWriter) WriteString(s string) (n int, err error) {
return g.writer.Write([]byte(s))
}
Link to original issue that includes pull request.
https://github.com/gin-gonic/contrib/pull/59
Once the owner of the project accepts the pull request this issue will be resolved.
