不含脂肪的收缩链接（F3）



缩短链接到13并不为耻，对吗？初学者，不仅是初学者，在学习新框架时应尝试编写自己的Link Tamer。这是我做的。我能说什么-第五个引导程序，一个没有脂肪的框架和灵魂。



这是代码。对于像我这样的读者；）



一个框架，对吗？



Laravel — 65- FatFreeFramework. Python Flask, , - :



#  
@app.route('/')
def hello_world():
    return 'Hello, World!'





//  
$f3->route('GET /',
    function() {
        echo 'Hello, world!';
    }
);

  • 您还可以通过/ @ code / stats进行常规统计并显示它
  • 禁止创建指向缩短服务本身的链接，创建“受保护”以防止缩短的资源列表
  • 我强烈建议即使在很小的事情上在服务器端进行输入验证，并输出相应的错误，您也不应依赖于在输入字段中添加必需的属性和type =“ url”
