java中获取http头信息

一、示例

使用request获取头信息

Enumeration e = request.getHeaderNames();while (e.hasMoreElements()) {String headerName = (String) e.nextElement();Enumeration<String> headerValues = request.getHeaders(headerName);while (headerValues.hasMoreElements()) {System.out.println(headerName + ":"+ headerValues.nextElement());}}

运行结果：

accept-encoding:gzip
connection:Keep-Alive
charset:UTF-8
content-type:multipart/form-data;
content-length:1372
user-agent:Dalvik/2.1.0 (Linux; U; Android 6.0.1; Redmi 4A MIUI/V8.2.4.0.MCCCNDL)
