Architecture Overview

Architecture Overview

eSight provides a group of Open API interfaces, and third-party developers can call open APIs by httpClient.

HttpClient is a client programming tool package that supports HTTP. HttpClient implements various methods, such as POST, GET, PUT, and DELETE. HttpClient interfaces must support HTTPS because eSight resources can be access only through HTTPS.

HttpClient developed by the Apache Jakarta Common project is based on Java. For its details, see http://hc.apache.org/httpcomponents-client-ga/index.html. Users can use HttpClient that is based on other languages to call open APIs.

Figure 3-1 shows the Open API architecture.

To invoke the open API, you need to perform URL encoding on parameters in the body of the HTTPS request. For example, when JAVA is used for development, you need to execute java.net.URLEncoder.encode(body, "UTF-8") on the parameters.
