【问题描述】：
我编写了应该更新模型对象实例的序列化程序和视图。 当我通过 Django Rest Browsable API 测试 API 时，该过程运行良好，但当我使用 curl 时却不行。 curl 请求（GET、PATCH 和 PUT）在服务器上显示 302 并且方法为 patch 时没有更新：
curl 命令是：
curl -X PATCH -H "Content-Type: application/json" -d '{ "status": "undefined", "started_at": "2022-03-31T08:22:54"}' http://localhost:8000/wf/machineworks/b79ac69b-e9a6-410b-bfbd-a79b0163f69a
对于 curl 命令，服务器给出：
[31/Mar/2020 12:50:33] "PATCH /wf/machineworks/b79ac69b-e9a6-410b-bfbd-a79b0163f69a HTTP/1.1" 302 0
而可浏览 api 中的相同更新提供：
[31/Mar/2020 13:20:25] "PATCH /fr/wf/machineworks/b79ac69b-e9a6-410b-bfbd-a79b0163f69a/ HTTP/1.1" 200 12588

我看到了许多与此问题相近的问题，但我没有找到任何有效的答案......看起来很简单，但我很迷茫......
【问题讨论】：
-
您的 django i18n 设置将请求重定向到
/wf/...到/en/wf/...。如您所见，您的 curl 与浏览器 api 的 url 不同。只需在您的 curl 请求中使用正确的 url（以语言en/或fr/开头）。或者为您的 API 调用禁用 url 重定向。 -
302 重定向总是会导致 GET，因此您必须避免在 API 中进行重定向。
-
哇！看起来很明显。如果我添加一些语言来为路径添加前缀，它现在可以工作。非常感谢@dirkgroten 的帮助。附属问题：有没有办法只为rest框架删除i18n？
-
Django 不会自动将语言前缀添加到 url，您已经要求 Django 通过在 URL 配置中添加
i18n_patterns来做到这一点。只需为那些应该拥有它的 URL 添加它，并为您在 API 中使用的 URL 删除它（例如，将其用于/blog，但不适用于/api。） -
好的。完美的 ！而已。你让我很快乐。 非常感谢 @dirkgroten
