{{$$ guid}} 是什么类型的变量？

What kind of variable is {{$guid}}? How can it be used in test scripts for API requests?

答

GUID是全局唯一标识符的缩写。 GUID主要用于产生十六进制数字，其组之间用连字符分隔，出于唯一性目的，例如：

GUID is the acronym for "Globally Unique Identifier". A GUID is mainly used to produce hexadecimal digits with groups separated by hyphens for uniqueness purposes, for example:

b3d27f9b-d21d-327c-164e-7fb6776f87b0

在邮递员中，您可以根据需要使用它生成并向您的api发送随机GUID：

In postman you can use this to generate and send a random GUID to your api as required:

{
    "id": "{{$guid}}",
}

在发送时会产生（带有上面的随机示例）：

On Send would produce(with the random example above):

{
    "id": "b3d27f9b-d21d-327c-164e-7fb6776f87b0",
}
