Cordova InAppBrowser loaderror事件未针对错误500触发 [英] Cordova InAppBrowser loaderror event not firing for Error 500

问题描述

我在InAppBrowser中遇到问题.我正在尝试捕获可能来自正在加载的网站的错误，而我正在通过错误的.htaccess进行模拟，该错误会产生错误500.

I have an issue with InAppBrowser. I am trying to catch errors that might come from the website I'm loading and I'm simulating this by a faulty .htaccess, which produces an error 500.

我有以下代码:

ref = cordova.InAppBrowser.open($openuri, '_blank', 'location=no,toolbar=no,zoom=no,enableviewportscale=no,disallowoverscroll=no');
ref.addEventListener("loadstop",function() {
        .....
    });
ref.addEventListener("loaderror",function() {
        alert('Toot');
    });
ref.addEventListener('loadstart', function(event) {
        .....
});

网站正在打开，所有"loadstop"和"loadstart"事件均正常运行.但是，当我故意使页面返回错误500"时，则不会触发"loaderror"事件.

The website is opening and all the "loadstop" and "loadstart" events work correctly. However, when I deliberately make the page return an "error 500", the event "loaderror" is not firing.

它确实会引发其他错误，例如电话上没有互联网时.

It does fire for other errors - like when there is no internet on the phone.

任何关于为什么发生这种情况的想法都受到高度赞赏.

Any ideas as to why this is happening are highly appreciated.

推荐答案

查看Android的InAppBrowser插件代码，它内部使用onReceivedError方法处理loaderror事件.所以我从Webview的角度看了这个问题，偶然发现了这个链接- https://code.google.com/p/android/issues/detail?id=968 ，其中指出onReceivedError函数并非旨在捕获HTTP错误.

Looking at InAppBrowser Plugin code for Android, it interally uses onReceivedError method for handling loaderror event. So i looked at this issue from webview perspective and stumbled on this link - https://code.google.com/p/android/issues/detail?id=968 which states that the onReceivedError function is not meant to catch HTTP errors.

对于HTTP错误处理，我们可能必须使用onReceivedHttpError函数，该函数不属于插件.我希望这对为什么不起作用是有道理的.

For HTTP error handling, we may have to use onReceivedHttpError function which is not part of the plugin. I hope it makes sense as to why this is not working.
