什麼？ 隨著網路的普及，很多人都搭建起了屬於自己的nextcloud私有網盤。而對於訪問量較大，公開性較強的私有網盤站點來說，許多人通常會使用CDN來保護自身免受攻擊。 使用了CDN之後對於私有網盤而言，繞不開的一個問題就是單文件上傳大小的限製，比如源站服務器允許1G大小單文件，到了CDN這裏卻只允許100M，於是用戶就只能上傳100M了，非常不方便。 嗯？ 繞過上傳限製的辦法麽 ～ 除了氪金，似乎就只有分片上傳了。好在nextcloud本身支持web界面開啟分片上傳，以下是具體方法（僅對web端有效，sync或者webdav仍然受單文件上傳大小限製）： 1.首先，確認自己的web服務器的php允許上傳大小在自己滿意的範圍。（修改php.ini的max_upload_file_size數值實現） 2.打開nextcloud根目錄，進入 apps/files/js目錄，找到 jquery.fileupload.js，並使用編輯器打開。 3.跳轉到154行附近，找到 maxChunkSize 這個選項。把這個選項後面的默認值改為其他數值。 默認情況：// To upload large files in smaller chunks, set the following option // to a preferred maximum chunk size. If set to 0, null or undefined, // or the browser does not support the required Blob API, files will // be uploaded as a whole. maxChunkSize: undefined, //就是這 // When a non-multipart upload or a chunked multipart upload has been // aborted, this option can be used to resume the upload by setting // it to the size of the already uploaded bytes. This option is most // useful when modifying the options object inside of the "add" or // "send" callbacks, as the options are cloned for each file upload. uploadedBytes: undefined, 例如可以修改為 100000000 （約合98MB），並保存退出：// To upload large files in smaller chunks, set the following option // to a preferred maximum chunk size. If set to 0, null or undefined, // or the browser does not support the required Blob API, files will // be uploaded as a whole. maxChunkSize: 100000000, //就是這 // When a non-multipart upload or a chunked multipart upload has been // aborted, this option can be used to resume the upload by setting // it to the size of the already uploaded bytes. This option is most // useful when modifying the options object inside of the "add" or // "send" callbacks, as the options are cloned for each file upload. uploadedBytes: undefined, 此時再打開web界面，刷新快取以後就可以上傳大於100M的單個文件了。 有什麽副作用？ 1.由於文件上傳完畢後需要服務器組合，如果網絡狀況不佳或者服務器配置跟不上訪問量，所以上傳特大文件時可能會突然遇到無響應問題。 2.上傳處理效能會變差很多。因為nextcloud對這方面並沒有優化。
