POST 405（方法不允许）在自定义网站上 api

Question

我有以下反应代码来调用 post 端点，webapi 确实有一个 post 但我仍然不知道为什么我会收到此错误

get 端点工作完美

Answer 1

如果您想访问 CreatePageTemplate 操作，您必须请求 url 以下格式：RoutePrefix + Route。在您的情况下，结果 url 应该是 api/Page + api/Page/CreatePageTemplate = api/Page/api/Page/CreatePageTemplate。但显然这段代码

adalApiFetch(fetch, "/Page/CreatePageTemplate", options)

请求api/Page/CreatePageTemplate。所以只需更新为以下

adalApiFetch(fetch, "/Page/api/Page/CreatePageTemplate", options)

但如果您打算使用原始 url，您应该只更新您的操作

[HttpPost]
[Route("CreatePageTemplate")] //remove api/Page as it is already in RoutePrefix
public async Task<IHttpActionResult> CreatePageTemplate([FromBody]PageTemplateCreationModel model)
