在Fine-Uploader中上传文件,上传成功后无法combine/merge块
Uploading files in Fine-Uploader, fail to combine/merge chunks after successful upload
所以我一直在努力让 Chunked uploading 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正在教学的完全菜鸟本人,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来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正常工作。
如果我上传的文件没有分块进入我的文件目录,我已经成功地将常规文件上传到文件文件夹中,但是如果我使用分块,它可以将文件分块并将其上传到我的 Chunks 目录中的一个文件夹,但我似乎无法弄清楚如何将它重新组合在一起并将其放入 Files 目录
我的 Firefox 控制台给了我这个响应并在完成分块上传文件后停止,不管我的代码中是否包含分块成功端点,这让我认为这与我的分块成功端点有关没有正确设置或按照这些路线设置。
[Fine Uploader 5.11.8] All chunks have been uploaded for 0 - finalizing....fine-uploader.js:162:21

我花了大约 2 天时间对此进行研究,但无济于事,我似乎没有遇到任何错误,但正如我所说,就我自己的理解而言,我几乎是一个菜鸟。非常感谢任何帮助。

感谢您帮助确保我的代码正确,为此我踢了自己的脸!正如我思考了最长的时间,错误地设置 Apache 环境一直是我所有问题的根源。
我没有 .htaccess 设置,它似乎可以解决我所有的问题。
以下是我解决问题所遵循的步骤。
第一步
打开apache.conf文件为
sudo vim /etc/apache2/apache2.conf
第二步
如果您在该行之前找到注释符号 (#),请将其删除(第 187 行大约)
AccessFileName .htaccess
第三步
然后找到有
的那一行
<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
将"None"替换为"All"
AllowOverride All
第四步
激活 ModRewrite:
sudo a2enmod rewrite
sudo service apache2 restart
一切都应该从这里开始。

感谢您帮助确保我的代码正确,为此我踢了自己的脸!正如我思考了最长的时间,错误地设置 Apache 环境一直是我所有问题的根源。
我没有 .htaccess 设置,它似乎可以解决我所有的问题。
以下是我解决问题所遵循的步骤。
第一步
打开apache.conf文件为
sudo vim /etc/apache2/apache2.conf
第二步
如果您在该行之前找到注释符号 (#),请将其删除(第 187 行大约)
AccessFileName .htaccess
第三步
然后找到有
的那一行<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride None
Require all granted
</Directory>
将"None"替换为"All"
AllowOverride All
第四步
激活 ModRewrite:
sudo a2enmod rewrite
sudo service apache2 restart
一切都应该从这里开始。
