HTML中的get请求和post请求

 

u Microsoft Internet Explorer has a maximum uniform resource locator (URL) length of 2,083 characters. Internet Explorer also has a maximum path length of 2,048 characters. This limit applies to both POST request and GET request URLs. 

If you are using the GET method, you are limited to a maximum of 2,048 characters, minus the number of characters in the actual path.

However, the POST method is not limited by the size of the URL for submitting name/value pairs. These pairs are transferred in the header and not in the URL. 

RFC 2616, "Hypertext Transfer Protocol -- HTTP/1.1," does not specify any requirement for URL length.  

1、ie对post请求和get请求的url有限制，都是2048个字符；

2、http协议并未对url长度做限制；

get请求和post请求的区别：

1、 Get方式在通过URL提交数据，数据在URL中可以看到；POST方式，数据放置在HTML HEADER内提交；

2、 get传送的数据量较小，不能大于2KB。post传送的数据量较大，一般被默认为不受限制。

3、 get安全性非常低，post安全性较高。但是执行效率却比Post方法好。
