### go gin框架v1.9.1修改版  
#### 1、fatal error: concurrent map read and map write  
/github.com/gin-gonic/gin/render/render.go:38  
```
func writeContentType(w http.ResponseWriter, value []string) {  
	header := w.Header()  
	if val := header["Content-Type"]; len(val) == 0 {  
		header["Content-Type"] = value  
	}  
}  
```
改为:  
```
func writeContentType(w http.ResponseWriter, value []string) {
	header := w.Header()
	RWMutex.Lock()
	defer RWMutex.Unlock()
	if val := header["Content-Type"]; len(val) == 0 {
		header["Content-Type"] = value
	}
}
```
