我知道这个错误意味着我的路由器没有处理这个请求。此路径是否应该

放置“/products/：id”

管理该请求？

为了将来的读者：

put "/products/:id"

映射到：

#                                ⇓⇓⇓
http://192.168.20.7:4000/products/76

不应：

#                                 ⇓⇓⇓⇓⇓⇓ 
http://192.168.20.7:4000/products/?id=76

后者被映射到

put "/products"

---

为了未来的读者：

put "/products/:id"

映射到：

#                                ⇓⇓⇓
http://192.168.20.7:4000/products/76

不应：

#                                 ⇓⇓⇓⇓⇓⇓ 
http://192.168.20.7:4000/products/?id=76

后者被映射到

put "/products"

请发布

mix phoenix.routes

的输出。另外，

put”/products/：id“

映射到

http://192.168.20.7:4000/products/76

不发送到

http://192.168.20.7:4000/products/?id=76
