钉钉开发 - 服务端API Asp.Net Core 发起审批实例

官方文档：https://ding-doc.dingtalk.com/doc#/serverapi2/cmct1a

我使用的接口：

/processinstance/create

发起审批实例 

-- 我遇到的主要问题是

{"errcode":820001,"errmsg":"发起审批实例失败，错误原因为【系统错误:审批表单缺少必填信息:设备类型】","request_id":"5ljo99cw3ujm"}

这个问题关键就是审批表单中我用了“明细”，官方demo中这个明细特别处理了，C#代码我给出来了。

// 明细
OapiProcessinstanceCreateRequest.FormComponentValueVo vo4 = new OapiProcessinstanceCreateRequest.FormComponentValueVo();
vo4.setName("明细示例");
vo4.setValue(JSON.toJSONString(Arrays.asList(Arrays.asList(ItemName1, ItemName2, ItemName3))));

 

基础东西看官方demo或者其他博客写的。 我这列出关键代码

此代码对应的自定义审批单：

/// <summary>
        /// 发起审批实例 - 设备及附件转场申请
        /// </summary>
        /// <returns></returns>
        public OapiProcessinstanceCreateResponse Create()
