使用HttpURLConnection 如何获取多个SetCookie

使用con.getHeaderField("Set-Cookie");
只能获取最后一个Set-Cookie
求解

Answer 1

1. 在app启动的源喊时候拆裂辩，设置一个cookiemanager的实例
写在APP的oncreate里面：
CookieSyncManager.createInstance(this);
2. 设置，获取
protected String getCookie() {
CookieManager cookieManager = CookieManager.getInstance();
String cookie = cookieManager.getCookie("cookie");
if (cookie != null) {
return cookie;
} else {
return "";
}
}
protected void setCookie(String cookie) {
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setCookie("cookie", cookie);
}
3. 过期按需处理一下
附1：cookie的获取
response.headerFields = conn.getHeaderFields();
setCookies(response.headerFields);

/**
* 存储cookie
* @param headerFields
*/
protected void setCookies(Map<String, List<String>旅缺> headerFields) {
if (null == headerFields) {
return;
}
List<String> cookies = headerFields.get(COOKIES_KEY);
if (null == cookies) {
return;
}
for (String cookie : cookies) {
setCookie(cookie);
}
}
COOKIE_KEY="Set-Cookie"

Answer 2

String cookieVal = null;
String key=null;
for (int i = 1; (key = http.getHeaderFieldKey(i)) != null; i++ ) {
if (key.equalsIgnoreCase("稿纳set-cookie")) {
cookieVal = http.getHeaderField(i);
cookieVal = cookieVal.substring(0, cookieVal.indexOf("纳敬旁;"));
sessionId=sessionId+cookieVal+";"洞橡;
}
}

Answer 3

getHeaderFields 返回的MAP 自己处理
