No idea where the data line you've used as an example is stored, so I've assumed it's in an environment variable line.
As for what you mean by the link - you could have specified which field you mean, or perhaps you mean the link specified as the data item public_url.
So - assuming your data is in line, use string-replace to delete {, [, etc. by replacing by nothing, then each ":" by "," and follow the bouncing ball...
Set the name(s) of the field(s) required to undefined (just a meaningful string, nothing magic) and process line with a simple for loop as a sequence of possibly-quoted tokens separated by commas.
The echo %%e command is simply for show to allow the token being evaluated to be seen.
assign_next is "set" to nothing before the for loop, so it will start as not defined
If a token matches a defined variable, then the next token contains the desired data, so set assign_next to the name of the variable to which to assign the next token.
If assign_next is defined, then assign the current token to the variablename contained in assign_next.

不知道您将其用作示例的数据行被存储在哪里，因此我假设它在环境变量
line中。至于
链接- 您可以指定您的意思是哪个字段，或者也许是指指定为数据项public_url的链接。因此 - 假设您的数据在
line中，请使用字符串replace删除{，[等。 /em>，然后每个“：”“”，“” 并遵循弹跳球...设置<<代码>未定义的（只是一个有意义的字符串，没有魔术）和过程
line，用简单的作为循环的简单作为可能引用的令牌的顺序。Echo %% E命令仅用于显示以允许评估令牌。nistion_next在循环之前 nothing匹配定义的变量，然后接下来的令牌包含所需的数据，因此将
nistion_next设置为 name 可以分配下一步标记的变量。如果定义了
nistion_next，则将当前令牌分配给nistion_next中包含的variablename。...并使用
