RuntimeError: You called this URL via PUT

使用request方法 post 提交数据正常，发现同样的数据格式经过，提交PUT方法报错如下:

You called this URL via PUT, but the URL doesn't end in a slash and you have APPEND_SLASH set. Django can't redirect to the slash URL while maintaining PUT data. Change your form to point to 127.0.0.1:8000/Host/9/ (note the trailing slash), or set APPEND_SLASH=False in your Django settings.

视图函数的路由和请求路径不同意统一，请求路径少了个/符号 实际上报错也有提示是 URL的问题，所以容易误导

在URL结尾加上 / 即可解决
