藥劑 - 塞 - 沒有功能語句匹配

我送這個PUT http請求：http://192.168.20.7:4000/products/?id=76 藥劑 - 塞 - 沒有功能語句匹配

我得到這個錯誤：

我在路由器來處理請求有這樣的：

put "/products/:id" do 
    IO.puts("putting image #{id}") 
    conn 
     |> put_resp_content_type("application/json") 
     |> send_resp(200, Poison.encode!(%{ 
      successs: "success" 
     })) 
    end

我知道錯誤意味着我的路由器沒有處理請求。該路徑不應該用put "/products/:id"來管理那個請求嗎？

請寄出'mix phoenix.routes'的輸出。 – mudasobwa

另外，'put「/ products /：id」'映射到'http：//192.168.20.7：4000/products/76'而不是'http://192.168.20.7:4000/products/?id=76 '。 – mudasobwa

@mudasobwa我不使用鳳凰。但我想你已經指出了我的錯誤。謝謝！ – user2602079

對於未來的讀者起見：

put "/products/:id"

被映射到：

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

不會：

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

後者映射到

put "/products"
