What is the difference between the SOAP and HTTP protocol. When we say "SOAP over HTTP", what does that mean.?

推荐答案

您可以通过HTTP提供任何内容，例如HTML，图像，声音，视频等.SOAP是基于XML的消息编码，通常通过HTTP，但可以通过SMTP甚至FTP发送，尽管我从未见过在生产环境中使用过这样的系统.

You can serve any content over HTTP such as HTML, images, sound, video, etc. SOAP is an XML-based encoding of messages that are typically sent over HTTP, but could be sent over SMTP or even FTP, although I've never seen such a system used in a production environment.

就像HTTP位于TCP/IP之上一样，SOAP也位于HTTP之上.层在层之上...

Just like HTTP sits on top of TCP/IP, SOAP sits on top of HTTP. Layers on top of layers...

如果查看SOAP请求，则可以看到两层，其中HTTP头位于顶部，后跟SOAP消息.从 w3schools SOAP教程:

If you look at a SOAP request, you can see both layers, with the HTTP headers at the top, followed by the SOAP message. From the w3schools SOAP tutorial:

---------  HTTP portion of the message ------ 
POST /InStock HTTP/1.1
Host: www.example.org
Content-Type: application/soap+xml; charset=utf-8
Content-Length: nnn

---------  SOAP portion of the message ------ 
<?xml version="1.0"?>
<soap:Envelope
xmlns:soap="http://www.w3.org/2001/12/soap-envelope"
soap:encodingStyle="http://www.w3.org/2001/12/soap-encoding">

<soap:Body xmlns:m="http://www.example.org/stock">
  <m:GetStockPrice>
    <m:StockName>IBM</m:StockName>
  </m:GetStockPrice>
</soap:Body>

</soap:Envelope>
