所以我一直试图让Chunked上传为我一直在做的项目工作，我对事物很陌生，事实上，对于所有密集的目的，你可以认为我是一个自学的完整的菜鸟，我正在使用网站上的手动上传模板和传统服务器端示例文件，以了解代码的工作原理，并尝试将它们拼凑成一个功能齐全的示例供我构建。我已经能够让大多数事情发挥作用。
我设法将常规文件成功上传到文件夹中，如果我上传文件而不进行分块就会进入我的文件目录，但是如果我使用分块它会将文件分块并上传到文件夹中在我的Chunks目录中，但我似乎无法弄清楚如何将它放回到一起并将其放在Files目录中
我的Firefox控制台为我提供了这个响应并在完成上传文件后停止，无论我的代码中是否包含我的分块成功端点，这让我觉得它与我的分块成功端点没有关系正确设置或沿着那些方向设置。
[Fine Uploader 5.11.8] All chunks have been uploaded for 0 - finalizing....fine-uploader.js:162:21

[Fine Uploader 5.11.8] Finalize successful for 0
我花了大约2天研究这个没有用，我似乎没有得到错误，但正如我所说的那样，在我自己理解这一点时，我几乎是一个Noob。任何帮助都会得到极大的赞赏。

答案 0 :(得分：0)
感谢您帮助我确保我的代码是正确的，为这个代码踢了自己！正如我想的那样，错误设置Apache环境已经成为我所有问题的根源。
我没有.htaccess设置，似乎解决了我的所有问题。
以下是我解决问题的步骤。
第一步
以
打开apache.conf文件sudo vim /etc/apache2/apache2.conf
第二步
如果您在此行之前找到注释符号（＃），则删除注释符号（＃）（行号187约）
AccessFileName .htaccess
第三步
然后找到
所在的行<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
替换＆＃34;无＆＃34;与＆＃34;所有＆＃34;
AllowOverride All
第四步
激活ModRewrite：
sudo a2enmod rewrite
sudo service apache2 restart
从这里一切都应该是好的。
