<p>我无法使用<code>application/octet-stream</code>类型的帖子获得一个工作请求，但在过去使用<code>multipart/form-data</code>类型的表单使用flask上载图像。</p>
<p>我已经扩展了过去所做的工作，以支持多个上传文件，并且利用了werkzeug的<code>FileStorage</code>对象。</p>
<p>这里的关键是设置一个基于post的路由，该路由从表单中查找请求元素。这应该允许您通过标准表单或AJAX调用发布到路由。</p>
<p>下面是一个使用表单的简化示例：</p>
<p><strong>视图模板：</strong></p>
<pre><code><!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8">
<title>jQuery File Upload Example</title>
</head>
<body>
{% if err %}
<h4>{{ err }}</h4>
{% endif %}
<form action="/" method=POST enctype=multipart/form-data id="fileupload">
<input type="file" name="files" data-url="/" multiple>
<input type=submit value=Post>
</form>
{% if files %}
{% for file in files %}
<p>Uploaded: <b>{{ file }}</b> </p>
{% endfor %}
{% endif %}
</body>
</html>
</code></pre>
<p><strong>烧瓶应用程序</strong></p>
<pre><code>from flask import Flask, request, render_template
