Let us see the differences between these two web services as enlisted in the below image. There are two types of web services, namely The question that arises here is, how exactly, within seconds, are they providing us with the information? What exactly do they do?įrom UI, they take all the necessary information and store it in a JSON or XML file and call their vendor APIs with an authentication token as they expose their APIs, and in response, the flight vendor’s site sends back JSON/XML response to MakeMyTrip, and they convert the received response and display details in UI. If they are booking through third-party vendors like MakeMyTrip and other booking sites, within a few seconds they will compare and show results providing flight details like the lowest price, flight time, and much more other information.

If a customer wants to book a flight from New York to London, either they can browse directly on the flight vendor portal or they can book through third-party vendors. and are some of the famous flight and hotel booking websites and there are different flight vendors available like Indigo, Air India, Etihad, etc. Refer to the example below to understand how web services work. Web services are generally APIs that are not installed or stored locally but are available in clouds or in some remote servers. Note that Unirest settings like timeouts or interceptors are not applied to custom clients.Web Services are a medium of communication between client and server machines that interacts over a network with the help of HTTP protocols. You can set your own custom Apache HttpClient and HttpAsyncClient. Unirest leverages Apache Http Client under the hood, this is not considered to be a permemant requirement and future versions of Unirest may replace Apache with something else.

This can be useful for logging or injecting common attributes. This is invoked before and after each request. You can set a global interceptor for your configuration. Set a default base URL to be used for all requests that do not already contain a scheme Set a custom HostNameVerifier for the security configuration Set a global Interceptor handler that will be invoked before and after each request

Set a global error handler that will be invoked for any status > 400 or a parsing error No persistent connection will be re-used past its TTL value.Īdd total time to live (TTL) by Duration. Total time to live (TTL) defines maximum life span of persistent connections regardless of their expiration setting. Toggle to add the clients to the system shutdown hooks automaticallyĪdd a PKCS12 KeyStore by path for doing client certificatesĪdd a PKCS12 KeyStore for doing client certificates Toggle disabling automatic retries (up to 4 times) for socket timeouts Acceptable values: ‘default’ (same as Netscape), ‘netscape’, ‘ignoreCookies’, ‘standard’ (RFC 6265 interoprability profile), ‘standard-strict’ (RFC 6265 strict profile) Good for setting trace tokens for microservice architectures.

Sets concurrency rates max total, max per route Sets the connection timeout for all requests in millis Sets the socket timeout for all requests in millis Once Unirest has been activated configuration options that are involved in creating the client cannot be changed without an explicit shutdown or reset. There are several background threads spawned by both Unirest itself and Apache HttpAsyncClient. addInterceptor ( new M圜ustomInterceptor ()) Ĭhanging Unirest’s config should ideally be done once, or rarely. setDefaultHeader ( "Accept", "application/json" ). Sometimes it was done on Unirest, sometimes it was done on Option, sometimes it was somewhere else.Īll configuration is now done through nfig() Previous versions of unirest had configuration split across several different places.
