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)
