Transcript of "Soap vs rest"

  1. 1. SOAP vs. RESTSOAP to wash and REST to relax Antonio Loureiro Severien FIB-UPC
  2. 2. What is SOAP? SOAP: Simple Object Access Protocol is a protocol for exchange of structured information on a decentralized and distributed platform using XML (eXtensible Markup Language) Works mainly with RPC (Remote Procedure Call) and HTTP (HyperText Transfer Protocol) HTTP makes SOAP go around
  3. 3. SOAP structure  3 parts message: Envelope, Header, Body POST /InStock HTTP/1.1ENVELOPE Host: www.example.org Content-Type: application/soap+xml; charset=utf-8 HTTHEADER Content-Length: 299 SOAPAction: "http://www.w3.org/2003/05/soap-envelope" P <?xml version="1.0"?> <soap:EnvelopeBODY xmlns:soap="http://www.w3.org/2003/05/soap-envelope"> <soap:Header> </soap:Header> <soap:Body> <m:GetStockPrice xmlns:m="http://www.example.org/stock"> FAULT <m:StockName>IBM</m:StockName> </m:GetStockPrice> </soap:Body> </soap:Envelope>
  4. 4. Simple Example REQUESTPOST /InStock HTTP/1.1Host: www.example.orgContent-Type: application/soap+xml; charset=utf-8Content-Length: nnn<?xml version="1.0"?><soap:Envelopexmlns: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>
  5. 5. Simple Example RESPONSEHTTP/1.1 200 OKContent-Type: application/soap+xml; charset=utf-8Content-Length: nnn<?xml version="1.0"?><soap:Envelopexmlns: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:GetStockPriceResponse> <m:Price>34.5</m:Price> </m:GetStockPriceResponse></soap:Body></soap:Envelope>
  6. 6. SOAP Characteristics, Pros andCons Implements its own protocol Exposes pieces of application logic, operations Advantages ◦ Versatile in use of different application protocols ◦ Tunnels easily through firewalls due to the use of HTTP model Disadvantages ◦ Slower when using large XML messages
  7. 7. What is REST? REST: Representational State Transfer focuses on accessing named resources through a consistent interface Every resource has its representation (could be a document) and the resource state changes when some method is applied through a request using any vocabulary
  8. 8. Constraints and Principles Client-server Cacheable Stateless Uniform interface Identification of resources Manipulation of resources Self-descriptive messages
  9. 9. SOAP vs. REST SOAP RPC: Application designers have to build up their protocol vocabulary whereas in REST it uses the well known vocabulary of the protocol in use REST: Different data formats where SOAP only allows XML REST has support for JSON, uses standard HTTP REST better performance and scalability SOAP reads cannot be cached
  10. 10. When to wash? When torelax? SOAP ◦ WS-Security: enterprise security features ◦ WS-AtomicTransactions: ACID compliant ◦ WS-ReliableMessaging: end-to-end reliability ◦ Ex.: smartphone app that communicates with a bank app on the web, need the previous implementations REST ◦ Lightweight ◦ Less complex for maintenance ◦ Bring the “web” back to web services
