我的ajax post 表現跟 put 一樣（put 用來編輯），但我正在添加新數據，如何糾正

我已經閱讀了所有template，並且我確實按照demo 做到8-9成，但仍然需要幫助，謝謝

-這個是主要送過去給伺服器的邏輯

$.ajax({
  url : 'http://192.168.01.10:8000/api/product/',
  type : 'POST',    // post for adding data
  dataType : 'json',
  contentType : 'application/json; charset=UTF-8', 
  data :JSON.stringify(send_Edit_API_Data) , 
  headers: {
    'Authorization': 'Bearer ' + getToken       // for authorized/safty reason
  },
  success : function(result) {
    console.log("SUCCESS", result)
  },
  error:  function(response){
    console.log("ERROR",response);
  }
});

我甚至添加了這個（這個tag 用於指示請求應該被視為 POST 請求，即使它作為 PUT 請求發送）但我看伺服器給的反饋，依舊像 put

      beforeSend: function(xhr) {
        xhr.setRequestHeader('X-HTTP-Method-Override', 'POST');
      },

        group: itemValue_data_group,


      }
      console.log("send_Edit_API_Data", send_Edit_API_Data);

      editRow(send_Edit_API_Data)
    }
  </script>
</body>
</html>

比如我要添加新data [adding new data][1]

1.我們點擊我網頁上的“Add New02”按鈕
2. 填寫新數據new data (device_id: 'string-new01' and etc) console 也有吃到
3. the new data is saved as "send_Edit_API_Data"
4. 用 ajax send to server
5. 當我refresh的時候, 剛加的 new data 沒有被新增?!

the {detail: 'No IPC with this device_id: string-new01 found'} 我猜想是 edit mode, the put method, 伺服器回傳 "No IPC with this device_id: string-new01 found"

https://ithelp.ithome.com.tw/upload/images/20230621/20160976SE9UWKSgHW.png

我目前是能想到

  • 我輸入的新數據有被整合，封包
  • 有確實給到伺服器(她都拿去比對了)
  • 但她以為是 put 而非 post

所以需要怎麼改?

Damm, I just found out, both "add" and "edit" button run save() function, in which only use editRow( ) api, therefore, (both inclouding) add is run as edit

這應該不是http method的問題，你用什麼http method去打，你可以在開發者模式下的網路那邊找到。
這個訊息看起來是你給的device_id不對。
要看後端程式碼才能確定，前端粗略看過應該沒問題。

我是新增新的 data, device_id 應該可以隨便寫才對。我有把 新的input 封包成"send_Edit_API_Data "，再寄給server。

- 從website 到 server 會失敗( 如本問題的post 變 put)
- 從fastAPI 介面就送一樣格式的資料就可以成功
froce iT邦大師 1 級 ‧ 2023-06-21 10:33:00 檢舉
你懷疑post變put你就去後端print一下接進來的request，和瀏覽器開發者模式裡網路打出來的封包比對一下就行，解決方法都告訴你了。

好，那我試試看

不好意思，我太菜了，還是不會，可以多講一下嗎?感恩
