要确切了解发生了什么，请使用 nc -l 或 ECHO 服务器和用户代理(如浏览器或 cURL).
To see exactly what is happening, use nc -l or an ECHO server and an user agent like a browser or cURL.
将表单保存到 .html 文件:
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>
创建要上传的文件:
echo 'Content of a.txt.' > a.txt
echo '<!DOCTYPE html><title>Content of a.html.</title>' > a.html
运行:
nc -l localhost 8000
在浏览器上打开 HTML，选择文件并点击提交并检查终端.
Open the HTML on your browser, select the files and click on submit and check the terminal.
nc 打印收到的请求.火狐发送:
nc prints the request received. Firefox sent:

或者，cURL 应该发送与浏览器表单相同的 POST 请求:
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
您可以使用以下方法进行多项测试:
You can do multiple tests with:
while true; do printf '' | nc -l localhost 8000; done
