如何在Azure Logic应用程序的步骤之间传递值？

Question

在Logic App的第一步中，我将我的API“登录”终结点称为ID /密码，并接收令牌。

如何在所有后续请求的标头中包含该令牌？

授权：承载令牌

我无法弄清楚如何从“登录”中读取响应并提取令牌，然后将其传递到以下所有调用的标头中。

这可能吗？

Answer 1

您需要将标记设置为变量的值，并在工作流中使用它。

Answer 2

我的方法如下。 1）假设您从登录HTTP操作获得的成功响应如下所示（示例取自Authorize access to Azure Active Directory web applications using the OAuth 2.0 code grant flow）

2）您将HTTP调用后的parse json操作添加到登录URL。使用您的登录api响应中的示例响应。 3）现在，解析JSON可让您访问响应中的各个字段 引用一个调用Microsoft AAD终结点的示例工作流程 -第一个黑框显示了您将调用响应发送到LogOn API的位置 -单击第二个黑框，并提供来自API的示例响应，以便引擎可以生成用于解析响应的架构 -第三个方框显示了如何传递接收到的access_token的值（根据上面添加的示例响应）
