Suppose you have this APIapi/regions/:id，真的是PUT方法，那你在浏览器里直接访问http://localhost:3000/api/regions/某一个ID，服务器肯定不允许。因为浏览器里URL形式访问是GET method.
Secondly, the API in the first picture is api/regions/:id，这里有:id。第二张图里浏览器里访问的是http://localhost:3000/api/regions，没有id. The two seem to have nothing to do with each other, so what do you want to ask?

Check whether the URL path of the resource request is written incorrectly
