Question

我有一个非常简单的ASP.NET Core应用程序，可以在我的本地计算机上完美运行。当我发布我的项目时，一切正常（GET，POST，DELETE）但不是部分更新（PATCH）。我使用JsonPatchDocument<T>。这是代码：

[HttpPatch("{id}")]
public IActionResult PartiallyUpdateNote(int id, [FromBody] JsonPatchDocument<NoteForUpdateDto> patches)
        {
            _log.LogInformation("Partial update of #{0}. Patches: {1}", id, patches);

            if (patches == null) // <------ THIS IS ALWAYS TRUE 
            {
                _log.LogError("Invalid patch format");
                return BadRequest("Invalid patch format?");
            }

这是我试图从邮递员发送的json：

PATCH http://tomasz.look24.net/api/notes/1
  标题：   内容类型=应用/ JSON
   原始：[{“op”：“替换”，“路径”：   “/ title”，“value”：“ne555e”}]

这是来自服务器的日志（单个补丁命中）：

我在2分钟后收到此日志并显示消息：

服务器错误

502 - Web服务器在充当a时收到无效响应   网关或代理服务器。您所在的页面存在问题   寻找，它无法显示。当Web服务器（同时   充当网关或代理）联系上游内容服务器，   它收到内容服务器的无效响应。

有什么不对？服务器配置中是否缺少某些内容？当我尝试将数据作为字符串获取时：

public IActionResult PartiallyUpdateNote(int id, [FromBody] string patches)

服务器端的一切都很好。必须有PartiallyUpdateNote（我相信）总是返回null。

Answer 1

我找到了解决方案。

当我将PATCH更改为POST

时，它可以正常工作

[HttpPost("{id}")]

我想知道为什么？

.NET核心补丁JsonPatchDocument在本地工作，但不在服务器上工作
