Android(安卓)WebView Authorization认证 (解决不认证报401的问题)

1.通过账号密码生成base64（http://www.bejson.com/enc/base64/）

账号admin密码admin

原数据：admin:admmin

base64:YWRtaW46YWRtaW4=

2.通过OKHTTP访问请求认证

 //第一个参数为用户名，第二个参数为密码        final String basic = "Basic YWRtaW46YWRtaW4=";//admin:admin==YWRtaW46YWRtaW4=;        OkHttpClient client = new OkHttpClient.Builder().authenticator(new okhttp3.Authenticator() {            @Nullable            @Override            public Request authenticate(@Nullable Route route, @NotNull Response response) throws IOException {                return response.request().newBuilder().header("Authorization", basic).build();            }        }).build();        Request request = new Request.Builder().url("http://http://127.0.0.1").build();        client.newCall(request).enqueue(new Callback() {            @Override            public void onFailure(Call call, IOException e) {                Log.d("Authorization", "onFailure: "+e.getMessage());                Toast.makeText(getApplicationContext(),"数据异常，请重新加载！",Toast.LENGTH_SHORT).show();            }            @Override            public void onResponse(Call call, Response response) throws IOException {                if (response.isSuccessful()) {                    Log.d("Authorization", "onResponse: "+response.body().string());                    handler.sendEmptyMessage(100);                }            }        });

3.在handler中调用webview

    private Handler handler = new Handler() {        @Override        public void handleMessage(Message msg) {            switch (msg.what) {                case 100:                    showWeb();                    break;            }        }    };  public void showWeb(){        WebView webView = findViewById(R.id.web1);        webView.setWebViewClient(new WebViewClient());        webView.loadUrl("http://127.0.0.1");        WebSettings mWebSettings = webView.getSettings();        //启用JavaScript。        mWebSettings.setJavaScriptEnabled(true);        mWebSettings.setUseWideViewPort(true);        mWebSettings.setJavaScriptCanOpenWindowsAutomatically(true);    }
