nginx搭建文件服务器获取上传进度

接上篇blog，主要讲讲获取上传进度的实现。 参考地址：https://github.com/masterzen/nginx-upload-progress-module

按照其中的说明配置nginx，将其中的例子存成test.html文件。放到nginx 的html目录下。 浏览器运行发现进度条不会变。 经过调试，发现nginx中缺少如下配置：

test.html里面缺少<script type="text/javascript" language="javascript"></scpript>

修改后重新测试：

成功获得上传进度。

nginx配置：

test.html：

<form id="upload" enctype="multipart/form-data"     action="/upload" method="post"     onsubmit="openProgressBar(); return true;">  <input type="hidden" name="MAX_FILE_SIZE" value="30000000"  />  <input name="userfile" type="file" label="fileupload" />  <input type="submit" value="Send File" />  </form>And a progress bar to visualize the progress:  <div>   <div id="progress" style="width: 400px; border: 1px solid black">    <div id="progressbar"        style="width: 1px; background-color: black; border: 1px solid white">          </div>   </div>   <div id="tp">(progress)</div>  </div>Then we need to generate the Unique Identifier and launch the upload on submitaction. This also will start the ajax progress report mechanism.<script type="text/javascript" language="javascript"> interval = null;function openProgressBar() { /* generate random progress-id */ uuid = ""; for (i = 0; i < 32; i++) {  uuid += Math.floor(Math.random() * 16).toString(16); } /* patch the form-action tag to include the progress-id */ document.getElementById("upload").action="/upload?X-Progress-ID=" + uuid; /* call the progress-updater every 1000ms */ interval = window.setInterval(   function () {     fetch(uuid);   },   1000 );}function fetch(uuid) { req = new XMLHttpRequest(); req.open("GET", "/progress", 1); req.setRequestHeader("X-Progress-ID", uuid); req.onreadystatechange = function () {  if (req.readyState == 4) {   if (req.status == 200) {    /* poor-man JSON parser */    var upload = eval(req.responseText);    document.getElementById('tp').innerHTML = upload.state;    /* change the width if the inner progress-bar */    if (upload.state == 'done' || upload.state == 'uploading') {     bar = document.getElementById('progressbar');     w = 400 * upload.received / upload.size;     bar.style.width = w + 'px';    }    /* we are done, stop the interval */    if (upload.state == 'done') {     window.clearTimeout(interval);    }   }  } } req.send(null);}</script>
