问题描述

我需要从一个 API 调用中获取一个令牌，以便在另一个 API 调用中使用它。

我试图以某种方式提取 access_token 部分，将其定义为我在第二次调用中使用的变量。

我的命令：

Invoke-RestMethod -Uri $URI_TOKEN -Method Post -Headers $HEADERS_TOKEN -Body $BODY_TOKEN | Select-String -pattern access_token

输出：

@{access_token=eyJhbGciOiJSUzI1NiIsInR5cCIgOiAiSldUIiwia2lkIiA6ICI4dDdPZUhRa1prall4SW1NWko3YVROanFMeW11WngwNWhvWTBxekxBbk1jIn0.eyJleHAiOjE2MTI4Mjg0OTMsImlhdCI6MTYxMjgyODQzMywianRpIjoiZGZkNTY5ZGUtYWUyZ

此输出包含我不需要的项目。是否可以提取以 access_token=blahblah 开头的字符串，直到;只有符号（基本上直到 expires_in=60）？

提前谢谢了！

解决方案

由于您已证明 的输出Invoke-RestMethod是 PSCustomObject，您可以通过执行以下操作简单地引用 access_token 属性：

$token = (Invoke-RestMethod -Uri $URI_TOKEN -Method Post -Headers $HEADERS_TOKEN -Body $BODY_TOKEN).access_token
