Android Webview里设置Cookie

Android中WebView加载网页，有时候需要通过cookie想网页传递信息，这时候这样操作。

Step 1 设置接收cookie

1
2
3

CookieManager.setAcceptFileSchemeCookies(true);
CookieManager.getInstance().setAcceptCookie(true);
CookieManager.setAcceptFileSchemeCookies(true);

Step 2 设置cookie的值，通过setcookie方法

1
2
3

List<String> cookies = new ArrayList<>();
cookies.add("app_key=" + App.getAppKey());
cookies.add("os=" + "Android" + Build.VERSION.SDK_INT);

Step 3 通过sync方法，将cookie同步

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
    CookieSyncManager.createInstance(context);
}
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.setAcceptCookie(true);
if (cookies != null) {
    for (String cookie : cookies) {
        cookieManager.setCookie(url, cookie);
    }
}
String s = "Domain=.***.com";
String s1 = "Path=/";
cookieManager.setCookie(url, s);
cookieManager.setCookie(url, s1);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP_MR1) {
    CookieManager.getInstance().flush();
} else {
    CookieSyncManager.getInstance().sync();
}

";Domain=.xxxx.xxx.com"+//作用域（在哪个域名下cookie起作用）
";Path=/";//Domain这个作用域下的哪个文件夹，“/”代表所有文件夹

注意

在调用设置Cookie之后不能再设置这类属性，否则设置Cookie无效。
