【问题描述】：
用例：
- 将定义一个 REST API 来处理由称为 (Postman REST Client) 的客户端作为附件发送的文件。
- 作为附件发送的文件将被发送到Zoho Task Creation Endpoint，以便使用文档创建任务。
注意：当我通过调用Zoho task Creation API 直接尝试使用邮递员时，它会使用文档创建任务。
谁能告诉我如何在 WSO2 EI 6.1.1 的 API 中实现这一点
邮递员：
当我将 log level="full" 放入 api 时，低于 log。
当我通过 Online Tool 对其进行解码时，它会提供如下所示的 base64 解码内容。
API 代码：
<?xml version="1.0" encoding="UTF-8"?>

</api>
API 响应：
{
"error": {
"code": 6831,
"message": "Input Parameter Missing"
}
}
原因：在调用 Zoho API 时需要将附件传递给名为“uploaddoc”的参数。这里我不知道如何设置该字段的附件

谁能给我一个解决方案？
【问题讨论】：
-
您可以在 EI 中调用 API，就像调用后端端点一样，带有文件附件。如果您的 API 调用该端点，EI 会将附件转发到该端点。

嗨@ThishaniLucas 感谢您的信息。我的疑问是我如何从 API 中的 RESTClient(Postman) 获取附件？“uploaddoc”是添加附件（“ZohoAttachment.txt”）的关键。根据上面的邮递员截图需要在调用外部端点时将附件传递给“uploaddoc”字段。你能帮帮我吗？等待你的回应..
