通过API中的WSO2 EI 6.1.1进行附件处理

Question

用例：

• REST将定义为将客户端(Postman客户端)发送的文件作为附件处理。
• 作为附件发送的文件将被发送到Zoho任务创建终结点，以便创建带有文档的任务。

Note：当我通过调用Zoho任务创建API直接尝试与邮递员打交道时，它用文档创建任务。

有谁能让我知道如何在WSO2 EI 6.1.1的API中实现这一点？

邮差：

​

​

当我将日志level=“完全”放入api中时，就会出现在日志下面。

​

​

当我通过在线工具对其进行解码时，base64解码的内容如下所示。

​

​

API代码：

API响应：

{
    "error": {
        "code": 6831,
        "message": "Input Parameter Missing"
    }
}

原因:在调用Zoho时，需要将附件传递给称为"uploaddoc“的参数。在这里，我不知道如何设置该字段的附件

有人能给我一个解决办法吗？

Answer 1

查看您的代码，您将不会对传入的有效负载做任何事情。那你为什么要调解有效载荷？穿过它就行了。

Answer 2

模拟zoho (使用任何简单的python、pip安装web服务器)和转储请求来自ESB，并查看请求中缺少什么。一些标题很可能丢失，内容处理内容-类型

API声明"name“参数是强制性的。
