HttpAuth是什么

HttpAuth是比较早的http的验证的一个方案

认证过程通过http协议来完成

WebView如何支持

HttpAuth本身是Http协议来支持，在Http的头有标记

WebView会有回调来方便客户端自己来自定义实现弹出框

WebView的内部类WebViewClient中的回调方法onReceivedHttpAuthRequest

WebView端实现

实现1，从url中根据规则获取用户名密码，自动填充，进行验证

url中没有用户名密码，实现弹窗，用户输入用户名密码后，根据填充内容进行验证

@Override

public void onReceivedHttpAuthRequest(WebView view,

final HttpAuthHandler handler, final String host,

final String realm) {

String username = null;

String password = null;

boolean reuseHttpAuthUsernamePassword = handler

.useHttpAuthUsernamePassword();

if (reuseHttpAuthUsernamePassword && view != null) {

String[] credentials = view.getHttpAuthUsernamePassword(host,

realm);

if (credentials != null && credentials.length == 2) {

username = credentials[0];

password = credentials[1];

}

}

if (username != null && password != null) {

handler.proceed(username, password);

} else {

if (isActive()) {

showHttpAuthentication(handler, host, realm, null, null,

null, 0);

} else {

handler.cancel();

}

}

}

httpAuth测试代码实现

使用flask完成最小httpauth原型

使用定义好的webview访问flask完成实现

浏览器上访问http://127.0.0.1:5000 可以弹出对话框说明实现完毕
