Json 动态字段来构造问题

怎么入门Golang编程？需要学习哪些知识点？这是新手们刚接触编程时常见的问题；下面golang学习网就来给大家整理分享一些知识点，希望能够给初学者一些帮助。本篇文章就来介绍《Json 动态字段来构造问题》，涉及到，有需要的可以收藏一下

每次我解决一个问题时，我都会遇到另一个类似但不同的问题。

我需要转换成json下面的struts，但是有些部分是动态的。我对这种转换不是很有经验，而且我很困惑。

下面我有两个不同的非静态字段（我能够在这个论坛的帮助下通过一个动态条目解决类似的问题，但现在我有两个）。 我将这些字段称为“此字符串更改”，因此不那么混乱。

[null,null,"hub:zwxkroom","presence_state",{"74ce1906-af89-48a9-aec7-501369509000":{"metas":[{"context":{"embed":false,"mobile":false},"permissions":{"close_hub":false,"embed_hub":false,"fly":true,"join_hub":true,"kick_users":false,"mute_users":false,"pin_objects":false,"spawn_and_move_media":true,"spawn_camera":true,"spawn_drawing":false,"spawn_emoji":true,"update_hub":false,"update_hub_promotion":false,"update_roles":false},"phx_ref":"tgjf9ixredi=","phx_ref_prev":"zj3pfzeyafm=","presence":"room","profile":{"avatarid":"3iadk9x","displayname":"real changeling"},"roles":{"creator":false,"owner":false,"signed_in":false}}]},"774e91d5-a324-47d7-ba75-edf9ed5bbe1a":{"metas":[{"context":{"embed":false,"mobile":false},"permissions":{"close_hub":false,"embed_hub":false,"fly":true,"join_hub":true,"kick_users":false,"mute_users":false,"pin_objects":false,"spawn_and_move_media":true,"spawn_camera":true,"spawn_drawing":false,"spawn_emoji":true,"update_hub":false,"update_hub_promotion":false,"update_roles":false},"phx_ref":"nnat0ypiaug=","phx_ref_prev":"tzv+xv6h0rs=","presence":"room","profile":{"avatarid":"pcj8sxb","displayname":"gobotwebsockets"},"roles":{"creator":false,"owner":false,"signed_in":false}}]},"9bd22f70-521a-49c2-9cb9-ac58dabfa1d6":{"metas":[{"context":{"embed":false,"mobile":false},"permissions":{"close_hub":false,"embed_hub":false,"fly":true,"join_hub":true,"kick_users":false,"mute_users":false,"pin_objects":false,"spawn_and_move_media":true,"spawn_camera":true,"spawn_drawing":false,"spawn_emoji":true,"update_hub":false,"update_hub_promotion":false,"update_roles":false},"phx_ref":"kpknfxlnkmo=","phx_ref_prev":"ia2es263vda=","presence":"room","profile":{"avatarid":"3iadk9x","displayname":"killab33z"},"roles":{"creator":false,"owner":false,"signed_in":false}}]},"f87b718a-c873-40a9-99db-91b4d0f7f4de":{"metas":[{"context":{"embed":false,"mobile":false},"permissions":{"close_hub":true,"embed_hub":true,"fly":true,"join_hub":true,"kick_users":true,"mute_users":true,"pin_objects":true,"spawn_and_move_media":true,"spawn_camera":true,"spawn_drawing":true,"spawn_emoji":true,"update_hub":true,"update_hub_promotion":false,"update_roles":true},"phx_ref":"xcct44iesao=","presence":"lobby","profile":{"avatarid":"https://s3.amazonaws.com/readyplayerbaker/avatars_baked/89e86e1a-43c7-4520-8f91-9a94ed42a722.glb","displayname":"rek2"},"roles":{"creator":true,"owner":true,"signed_in":true}}]}}]

在某人的大力帮助下，我能够转换一个非常相似的，但有两个我似乎无法让它工作。我不断得到空结果..

类似的方法在这里

我尝试过使用上面的字段和其他类似的东西进行复制。 我已经查看了很多关于这种情况的博客，但没有运气。

我也尝试过这个工具，但并没有真正起作用，因为该工具不知道细节

[编辑2] 我做了很多次尝试，但仍然没有打印任何东西！ 就像没有数据但有数据...有人可以检查我的代码并看看我做错了什么吗？我按照教程一步步完成的最后一个，仍然没有显示任何数据，我希望它这样做至少我知道要改变什么.. https://gitlab.com/rek2/gohubsbot/-/blob/master/websocketslisten.go 谢谢

解决方案

好吧，经过大量的调试、阅读、阅读、击中我的头并剥离 json，以便更简单地在 json to go 工具上发布...我终于明白了.. 主要问题？

//the type needs to be a map itself
type presencestate map[string]state

另外：

// even do I did try  this above I never called it the right way before so was giving up and moving on... but I have to use a pointer

for k, o := range *v {}

现在正在工作。当登录或更改时存在状态时，我会获取密钥和对象，以便我可以将 id 映射到用户名
