I cannot work out how to pass a variable with a boolean value of false through a URL string. What is the correct method?

• domain/page?test = false
• 域/页面?test =
• 域/页面?test = 0

推荐答案

URL是字符串，URL中的所有值都是字符串.当您在URL中看到i=0时，0是一个字符串.当您看到b=true时，true是一个字符串.当您看到s=时，该值是一个空字符串.

URLs are strings and all values in a URL are strings. When you see i=0 in a URL, 0 is a string. When you see b=true, true is a string. When you see s=, the value is an empty string.

要使这些字符串具有另一种含义(例如，整数0或布尔值true)，必须告知服务器端程序如何解释它们.通常，Web框架会对正确的类型做出明智的猜测，或者有时在模型中明确声明类型.

For those strings to take on another meaning—the integer 0 or the Boolean true, say—the server-side program must be told how to interpret them. Often web frameworks will make intelligent guesses as to the right type, or sometimes a type is declared explicitly in a model.

如何执行完全取决于所使用的服务器端语言和框架(如果有).

How you'll do it depends entirely on what server-side language and what framework, if any, you're using.
