You can get a template and render it with get_template [ 1 ].您可以获取模板并使用get_template [ 1 ] 进行渲染。 You can then yield your rendered template with:然后，您可以使用以下命令生成渲染的模板：
def process(request):
ip=request.POST.get('ip')
template = get_template("result.html")
with subprocess.Popen(['ping', '-c5',ip], stdout=subprocess.PIPE, bufsize=1, universal_newlines=True) as p:
for line in p.stdout:
yield(template.render({"line": line})
if p.returncode != 0:
raise subprocess.CalledProcessError(p.returncode, p.args)
For a template result.html :对于模板result.html ：
<html>
<title>Fetcher Results</title>
<body>
<div style='background-color:black;padding:10px'>
<pre style='font-size:1.0rem;color:#9bee9b;text-align: center;'>
<center>{{ line }}</center>
</pre>
</div>
</body>
</html>
However, do be aware that the StreamingHttpResponse will concat the template results and you will have a effectively several full <html>...</html> in your result.但是，请注意StreamingHttpResponse将连接模板结果，您的结果中将有效地包含几个完整的<html>...</html> 。
