要准确查看发生了什么，请使用 nc -l </ code>或ECHO服务器和用户代理如浏览器或cURL。
将表单保存为 .html 文件：
< form action =http：// localhost：8000method =postenctype =multipart / form-data>
< p>< input type =textname =textvalue =text default>
< p>< input type =filename =file1>
< p>< input type =filename =file2>
< p><按钮类型=提交>提交< /按钮>
< / form>
创建要上传的文件：
echo'a.txt。的内容> a.txt
echo'<！DOCTYPE html>< title> a.html的内容。< / title>> a.html
运行：
nc -l localhost 8000
在您的浏览器中打开HTML，选择文件并点击提交并检查终端。
nc 会打印收到的请求。 Firefox发送：
$ p $ POST / HTTP / 1.1
主机：localhost：8000
用户代理：Mozilla /5.0（X11; Ubuntu; Linux i686; rv：29.0）Gecko / 20100101 Firefox / 29.0

另外，cURL应该发送与浏览器表单相同的POST请求：
nc -l localhost 8000
curl -Ftext = default-Ffile1=@a.html-Ffile1=@a.txtlocalhost：8000
您可以使用以下方式进行多项测试：
while true;做printf''| nc -l localhost 8000;完成
I am wondering if anyone can share with me an example of multipart/form-data that contains:
- Some form parameters
- Multiple files
EDIT: I am maintaining a similar, but more in-depth answer at: https://stackoverflow.com/a/28380690/895245
To see exactly what is happening, use nc -l or an ECHO server and an user agent like a browser or cURL.
Save the form to an .html file:
<form action="http://localhost:8000" method="post" enctype="multipart/form-data">
<p><input type="text" name="text" value="text default">
<p><input type="file" name="file1">
<p><input type="file" name="file2">
<p><button type="submit">Submit</button>
</form>
Create files to upload:
echo 'Content of a.txt.' > a.txt
echo '<!DOCTYPE html><title>Content of a.html.</title>' > a.html
Run:
nc -l localhost 8000
Open the HTML on your browser, select the files and click on submit and check the terminal.
nc prints the request received. Firefox sent:
POST / HTTP/1.1
Host: localhost:8000
User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:29.0) Gecko/20100101 Firefox/29.0

Aternativelly, cURL should send the same POST request as your a browser form:
nc -l localhost 8000
curl -F "text=default" -F "file1=@a.html" -F "file1=@a.txt" localhost:8000
You can do multiple tests with:
while true; do printf '' | nc -l localhost 8000; done
