Class SimpleHttpClient

java.lang.Object

com.alibaba.csp.sentinel.transport.heartbeat.client.SimpleHttpClient

public class SimpleHttpClient
extends Object

A very simple HTTP client that only supports GET/POST method and plain text request body. The Content-Type header is always set as

application/x-www-form-urlencoded

. All parameters in the request will be encoded using URLEncoder.encode(String, String).

The result of a HTTP invocation will be wrapped as a SimpleHttpResponse. Content in response body will be automatically decoded to string with provided charset.

This is a blocking and synchronous client, so an invocation will await the response until timeout exceed.

Note that this is a very NAIVE client, Content-Length must be specified in the HTTP response header, otherwise, the response body will be dropped. All other body type such as Transfer-Encoding: chunked, Transfer-Encoding: deflate are not supported.
