gin框架接口返回时，context.String()方法报i/o timeout的panic错误

接口是正常的返回data数据，然后调用流程如下： respose := gin.H{"errNo": 0, "errStr": "success", "data": data} body, err := jsoniter.Marshal(respose) if err != nil { ctx.String(200, `{"errNo":0,"errStr":"success","data":{}}`) } ctx.String(200, exbytes.ToString(body)) 报错如下： err[write tcp 192.168.130.43:8913->192.168.130.26:35126: i/o timeout] stack[goroutine 13045825 [running]: runtime/debug.Stack(0xc00038d800, 0xf13400, 0xc00021c140) /home/homework/goroot/go1.13.5/src/runtime/debug/stack.go:24 +0x9d mainstation/web/middleware.Recovery.func1.1(0xc0000f2e70) /home/homework/localBuildPath/go/kid/mainstation/8f841112f7cbe4891e0d9f21d572dbc1/src/mainstation/web/middleware/recovery.go:20 +0xa6 panic(0xf134e0, 0xc0000dc000) /home/homework/goroot/go1.13.5/src/runtime/panic.go:679 +0x1b2 github.com/gin-gonic/gin.(*Context).Render(0xc0000f2e70, 0xc8, 0x11d0560, 0xc000544210) /home/homework/go/pkg/mod/github.com/gin-gonic/gin@v1.4.0/context.go:769 +0x16c github.com/gin-gonic/gin.(*Context).String(...)
