Visual studio 在'中传递不记名令牌；网络测试&x27；没有VisualStudio？

我想在Azure的Application Insights可用性功能中导入“.webtest”。我没有Visual Studio的测试版，但建议使用Fiddler作为创建web测试的另一个选项

我需要在REST API上执行2个请求：

从

connect/token

端点请求承载令牌

在头中使用承载令牌（从上述请求中检索）执行GET at

api/resources

这是典型的客户端凭证OAuth 2流

我似乎想不出怎么用Fiddler来做这件事。基本上，我需要从请求1的响应体中提取一个值，并将其用作请求2中的头值

这是web测试在不传递令牌的情况下的外观：

<?xml version="1.0" encoding="utf-8"?>
<TestCase Name="FiddlerGeneratedWebTest" Id="" Owner="" Description="" Priority="0" Enabled="True" CssProjectStructure="" CssIteration="" DeploymentItemsEditable="" CredentialUserName="" CredentialPassword="" PreAuthenticate="True" Proxy="" RequestCallbackClass="" TestCaseCallbackClass="">

        <FormPostParameter Name="client_secret" Value="password123" UrlEncode="True" />
        <FormPostParameter Name="grant_type" Value="client_credentials" UrlEncode="True" />
        <FormPostParameter Name="scope" Value="myscopes" UrlEncode="True" />

      <Headers>
        <Header Name="Authorization" Value="Bearer {{token}}" />
      </Headers>
    </Request>
  </Items>
</TestCase>

假设这是下面的示例，您可以使用正则表达式提取来获取它

{“令牌类型”：“承载”、“作用域”：“用户模拟”、“到期日”：“3600…”“访问令牌”：“{{令牌}”，…}

如果您需要通过发布JSON登录到，请向致意：

{
  user: 'youruser', 
  password: 'yourpassword'
}

first base64对json进行编码：

> echo "{user: 'youruser', password: 'yourpassword'}" | base64

然后在StringHttpBody标记中传递此base64值

很好。有没有办法在没有VS测试版本的情况下编写这样的测试？从我所看到的，Fiddler除了录制和回放请求之外，做不了更多的事情。
