Class HttpHeaders

java.lang.Object
  com.foxinmy.weixin4j.http.HttpHeaders

All Implemented Interfaces:

MultiValueMap<String,String>, Serializable, Map<String,List<String>>

public class HttpHeaders
extends Object
implements MultiValueMap<String,String>, Serializable

Represents HTTP request and response headers, mapping string header names to list of string values.

In addition to the normal methods defined by Map, this class offers the following convenience methods:

• getFirst(String) returns the first value associated with a given header name
• add(String, String) adds a header value to the list of values for a header name
• set(String, String) sets the header value to a single string value

Since:

3.0
