如何解决通过 Volley Multi-part Request 将捕获的图像发送到本地烧瓶服务器；但是我从我的烧瓶服务器得到了一个代码 302
我正在制作一个应用程序，可以拍照然后将其发送到服务器进行一些图像处理，但是当我将图像发送到服务器时，我收到“POST/HTTP/1.1”302，它正在重定向我的图像，并且不知道怎么解决
这是我的html表单代码
export PATH="$HOME/.composer/vendor/bin:$PATH"
这是我安卓工作室的代码
<!doctype html>
</p>
{% if filename %}
<div>
<img src="{{ url_for('display_image',filename=filename) }}">
</div>
{% endif %}
<form method="post" action="/" enctype="multipart/form-data">
<dl>
<p>
<input type="file" name="file" autocomplete="off" required>
</p>
</dl>
<p>
<input type="submit" value="Submit">
</p>
</form>
这是烧瓶代码
