Node.JS單個插槽，多個事件（上傳）

Question

我正在開發一個上傳跟蹤器（進度條等）。

所以對於我的前端我使用jQuery文件上傳。 後端上傳是使用單獨的工作人員完成的，我使用Redis pub/sub。 所以要連接前端和後端，我使用Node.JS（socket.io）。

jQuery文件上傳有一個「done」回調函數，表示將我們的文件傳到服務器。

這對單個文件絕對正常。

當我嘗試同時上傳2+文件時出現問題。 「完成」回調函數被越來越重視到插座聽衆2+倍（糾正我，如果我錯了），並作爲輸出我得到的是這樣的：

579 " - progress: " 8.333333333333334 
580 " - progress: " 8.333333333333334 
579 " - progress: " 16.666666666666668 
580 " - progress: " 16.666666666666668 
579 " - progress: " 25 
580 " - progress: " 25 
.... 
579 " -> upload is finished!" 
580 " -> upload is finished!" 

這是上傳2個文件的一個例子。這根本沒有任何意義，因爲它們只能被一個接一個地處理。

因此，它應該是這樣的：

579 " - progress: " 8.333333333333334 
579 " - progress: " 16.666666666666668 
579 " - progress: " 25 
.... 

579 " -> upload is finished!" 
580 " - progress: " 8.333333333333334 
580 " - progress: " 16.666666666666668 
.... 
580 " -> upload is finished!" 

Node.js的服務器端工作完全正常。 這是一個日誌從它：

RECEIVED progress FROM upload-579 
RECEIVED progress FROM upload-579 
RECEIVED progress FROM upload-579 
RECEIVED progress FROM upload-579 
RECEIVED progress FROM upload-579 
RECEIVED progress FROM upload-579 
RECEIVED progress FROM upload-579 
RECEIVED progress FROM upload-579 
RECEIVED progress FROM upload-579 
RECEIVED progress FROM upload-579 
RECEIVED progress FROM upload-579 
RECEIVED done FROM upload-579 
RECEIVED progress FROM upload-580 
RECEIVED progress FROM upload-580 
RECEIVED progress FROM upload-580 
RECEIVED progress FROM upload-580 
RECEIVED progress FROM upload-580 
RECEIVED progress FROM upload-580 
RECEIVED progress FROM upload-580 
RECEIVED progress FROM upload-580 
RECEIVED progress FROM upload-580 
RECEIVED progress FROM upload-580 
RECEIVED progress FROM upload-580 
RECEIVED done FROM upload-580 

它接收從Redis的信道消息，並且發射相應的消息至客戶端。 我認爲問題出在客戶端，但我無法弄清楚如何修改代碼以獲得我想要的。 可以做些什麼來將它們彼此分開？

P.S

在客戶端的套接字事件回調將觸發任何發射從Node.js的消息這就是爲什麼你看到重複的日誌消息。發送套接字消息中的附加數據，或附加唯一事件。
