最近遇到一個問題，在webview裡面載入https url的時候，如果裡面需要載入http的資源或者重定向的時候，webview會block頁面載入。

錯誤資訊如下：

chromium: [INFO:CONSOLE(0)] "Mixed Content: The page at 'https://iot.onehaier.com/v2/cms/advert.detail.h5?advertId=201612141722070002' was loaded over HTTPS, but requested an insecure image 'http://onehaiercms.oss-cn-qingdao.aliyuncs.com/2016/12/14/17-21-340871526087485.jpg'. This request has been blocked; the content must be served over HTTPS., source: https://iot.onehaier.com/v2/cms/advert.detail.h5?advertId=201612141722070002 (0)

修改內容如下：

//開啟DOM儲存API
settings.setDomStorageEnabled(true);
settings.setAllowFileAccess(true);
settings.setAppCacheEnabled(true);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    settings.setMixedContentMode(WebSettings.MIXED_CONTENT_ALWAYS_ALLOW);
}
