* Update README.md
c:\>curl 0.0.0.0:8080
"Failed to connect to 0.0.0.0 port 8080: Address not available"
Connecting to address 0.0.0.0:8080 is not allowed on windows. From http://msdn.microsoft.com/en-us/library/aa923167.aspx
" ... If the address member of the structure specified by the name parameter is
all zeroes, connect will return the error WSAEADDRNOTAVAIL. ..."
* Update README.md
edit comment
* Relocate binding body tests
Every test file should be related to a tested file.
Remove useless tests.
* Add github.com/stretchr/testify/require package
``` go
func main() {
r := gin.Default()
// r.GET("/JSONP?callback=x", func(c *gin.Context) { // old
r.GET("/JSONP", func(c *gin.Context) { // new
data := gin.H{
"foo": "bar",
}
//callback is x
// Will output : x({\"foo\":\"bar\"})
c.JSONP(http.StatusOK, data)
})
// Listen and serve on 0.0.0.0:8080
r.Run(":8080")
}
// client
// curl http://127.0.0.1:8080/JSONP?callback=x
// old output
// 404 page not found
// new output
// x({"foo":"bar"})
```
Most of the sample code in the documentation map[string]interface{} is represented by gin.H.
gin.H is a very important place for me to like gin, can write a lot less code
* support bind http header param #1956
update #1956
```
package main
import (
"fmt"
"github.com/gin-gonic/gin"
)
type testHeader struct {
Rate int `header:"Rate"`
Domain string `header:"Domain"`
}
func main() {
r := gin.Default()
r.GET("/", func(c *gin.Context) {
h := testHeader{}
if err := c.ShouldBindHeader(&h); err != nil {
c.JSON(200, err)
}
fmt.Printf("%#v\n", h)
c.JSON(200, gin.H{"Rate": h.Rate, "Domain": h.Domain})
})
r.Run()
// client
// curl -H "rate:300" -H "domain:music" 127.0.0.1:8080/
// output
// {"Domain":"music","Rate":300}
}
```
* add unit test
* Modify the code to get the http header
When the http header is obtained in the standard library,
the key value will be modified by the CanonicalMIMEHeaderKey function,
and finally the value of the http header will be obtained from the map.
As follows.
```go
func (h MIMEHeader) Get(key string) string {
// ...
v := h[CanonicalMIMEHeaderKey(key)]
// ...
}
```
This pr also follows this modification
* Thanks to vkd for suggestions, modifying code
* Increase test coverage
env GOPATH=`pwd` go test github.com/gin-gonic/gin/binding -coverprofile=cover.prof
ok github.com/gin-gonic/gin/binding 0.015s coverage: 100.0% of statements
* Rollback check code
* add use case to README.md
