Question

我正在使用D2L API，并且遇到一些POST请求有困难。

使用JSON对象执行版本检查（POST）：

[{ "ProductCode": "lp", "Version": "1.0" }]

正确返回，为我提供了一个有效的JSON对象作为响应，据说我有信心我的代码发出呼叫是正常的。

但是，当我发布POST以在论坛中创建帖子时，我得到了404响应。我正在为此调用发送的JSON对象是：

[
 {
 "ParentPostId": null,
 "Subject": "API Posted",
 "Message": {
   "Text": "This message has been posted by the API",
   "HTML": "This message has been posted by the API"
   },
 "IsAnonymous": false
 }
]

提交的网址为/d2l/api/le/{ver}/{orgId}/discussions/forums/{forumId}/topics/{topicId}/posts/

我已经使用相同论坛和主题中的帖子的GET验证了ver / orgId / forumId / topicId都是有效的。我也试过单独和同时引用ParentPostId和IsAnonymous的值。

Answer 1

在http://docs.valence.desire2learn.com/res/discuss.html#post--d2l-api-le-(D2LVERSION-version)-(D2LID-orgUnitId)-discussions-forums-(D2LID-forumId)-topics-(D2LID-topicId)-posts-查看该路线的文档，看起来所需的数据结构使用RichTextInput而不是RichText Message。

尝试将Message字段更改为：

{
   "Content": "This message has been posted by the API",
   "Type": "Text"
}

Answer 2

尝试从JSON中删除方括号。

成功请求和响应的示例如下：
