HTTP POST和GET的区别

1、HTTP 只有POST和GET 两种命令模式;

2、POST是被设计用来向上放东西的,而GET是被设计用来从服务器取东西的,GET也能够向服务器传送较少的数据,而Get之所以也能传送数据,只是用来设计告诉服务器,你到底需要什么样的数据.POST的信息作为HTTP 请求的内容,而GET是在HTTP 头部传输的;

3、POST与GET在HTTP 中传送的方式不同,GET的参数是在HTTP 的头部传送的,而Post的数据则是在HTTP 请求的内容里传送;

4、POST传输数据时,不需要在URL中显示出来,而GET方法要在URL中显示;

5、GET方法由于受到URL长度的限制,只能传递大约1024字节;POST传输的数据量大,可以达到2M,而根据微软方面的说法,微软对用 Request.Form() 可接收的最大数据有限制,IIS 4 中为 80 KB 字节,IIS 5 中为 100 KB 字节;

6、SOAP是依赖于HTTP POST模式实现的;

 

例子:

HTTP GET

发送

GET /DEMOWebServices2.8/Service.asmx/CancelOrder?UserID=string&PWD=string&OrderConfirmation=string HTTP/1.1

Content-Type: text/xml; charset=utf-8
Content-Length: length

<?xml version="1.0" encoding="utf-8"?>
<objPlaceOrderResponse xmlns="https://api.efxnow.com/webservices2.3">
  <Success>boolean</Success>
  <ErrorDescription>string</ErrorDescription>
  <ErrorNumber>int</ErrorNumber>
  <CustomerOrderReference>long</CustomerOrderReference>
  <OrderConfirmation>string</OrderConfirmation>
  <CustomerDealRef>string</CustomerDealRef>
</objPlaceOrderResponse>

 

HTTP POST
