我认为您的问题是由$.ajaxFileUpload配置中的相对url引起的。
为$.ajaxFileUpload
提供url
键时，请尝试在javascript代码中使用绝对url
您可以使用php中的基本url创建一个javascript变量，在您的视图中使用如下内容：
// in <head> or somewhere near the top before any other <script> tag
<script>
    var BASE_URL = '<?php print base_url(); ?>';
</script>

// in <head> or somewhere near the top before any other <script> tag
<script>
    var BASE_URL = '<?php print base_url(); ?>';
</script>

// ...
  $.ajaxFileUpload({
     url: window.BASE_URL+'/upload/upload_file/', 
// ....
