从以上URL看,关键在于key,这个key必须符合map的定义,[]外面的必须相同,也就是ids这个map变量名,[]里面的,也就是map的key不能相同,这样就满足了Gin定义的把URL查询参数转换为map的格式定义。 1 2 3 r.GET("/map", func(c *gin.Context) { c.JSON(200, c.QueryMap("ids")) }) 获取
而且 Golang 的 Map,KV 是储存在 bucket 里,一个 bucket 存在 8 个 slot,所以在量很小时,实际上最后申请的内存空间差不多。 但这依然是个优化,因为 Map 每次增长都需要重算 hash,但一开始设置好容量就可以避免这部分 CPU 占用。 3.3.2 字符串处理 然后看第三个函数 AccessLog: 还是和 OtherInfo 有关,...

r.Form map In our code above, we accessed the form values via the r.PostForm map. But an alternative approach is to use the (subtly different) r.Form map. The r.PostForm map is populated only for POST, PATCH and PUT requests, and contains the form data from the request body. In ...
