Java servlet 处理应用程序/八位字节流用于图像上传

Question

我有一个上传图像的http请求(application/octet-stream)。我不知道如何从服务器端(java spring servlet)接收这个应用程序/八位字节流。 我尝试这样做

request.getPart("ax_file_input");

但我得到了空。

请求如下所示:

标题:

Accept:*/*
Accept-Encoding:gzip, deflate
Accept-Language:en-US,en;q=0.8,zh-TW;q=0.6,zh;q=0.4,ja;q=0.2
Connection:keep-alive
Content-Length:27530
Content-Type:multipart/form-data; boundary=----       WebKitFormBoundarymuhts7ls9NLoqkUW

Apache commons fileupload 可用于解析多部分请求(这是上传文件所需的)。

这里有一个例子: http://codingitforward.blogspot.com/2010/01/java-upload-servlet.html
