request body使用ShouldBind绑定结构体，form参数带下划线就获取不到

[ChZhg123]

客户端参数 { id:20 sign:90cb901a631a3260c59d90724e893da9 timestamp:1681459261 role_id:3 } 注意：不是表单key value格式，是整个json数据 后端处理 type ArticleCommentLikeForm struct { ID int32 form:"id" alias:"ID" binding:"required" Timestamp int32 form:"timestamp" alias:"文章ID" binding:"required" Sign string form:"sign" alias:"文章ID" binding:"required" RoleId int32 form:"role_id" alias:"角色ID" binding:"required" } var param ArticleCommentLikeForm err := ctx.ShouldBind(&param); 获取不到RoleId的值
