PhoneGap的Andr​​oid应用Ajax请求到HTTPS失败，状态0

问题描述

阿贾克斯HTTPS从我在Android上的PhoneGap /科尔多瓦App请求莫名其妙地失败，状态= 0。它仅在签署同放钥匙的应用程序（例如，ADT的出口），但与调试密钥签名（直接在模拟器或手机上运行）时，不会出现出现。

Ajax HTTPS requests from my PhoneGap/Cordova app on Android inexplicably fail with status=0. It appears only when signing the app with the release key (i.e., exporting from ADT), but doesn't appear when signing with debug key (running directly in emulator or phone).

request = new XMLHttpRequest()
request.open "GET", "https://some.domain/", true
request.onreadystatechange = ->
  console.log "** state = " + request.readyState
  if request.readyState is 4
      console.log "** status = " + request.status

request.send()

总是输出

** state = 4
** status = 0

没关系，如果我请从Play商店或亚洲开发银行实用的应用程序。我presume它可以使用证书进行连接，因为不是所有的HTTPS域失败这种方式。

It doesn't matter if i install the app from Play Store or with adb utility. I presume it could be connected with the certificate, since not all HTTPS domains fail this way.

推荐答案

它发生时，所请求的URL与错误或自签名证书响应。在测试或发布应用程序的朋友，设定＆lt;应用机器人：可调试=真正的...＆GT; 在的Andr​​oidManifest.xml 就足够了 - 它会自动绕过证书错误

It happens when the requested URL responds with an erroneous or self-signed certificate. While testing or distributing the app to friends, setting <application android:debuggable="true"...> in AndroidManifest.xml is enough — it automatically bypasses certificate errors.

不过，谷歌Play商店将不会接受一个APK与机器人：可调试=真正的。首先，证书，当然，需要固定。不过，虽然出现这种情况，这里是一个解决方法的PhoneGap /科尔多瓦3：

But Google Play Store will not accept an APK with android:debuggable="true". First of all, the certificates, of course, need to be fixed. But while that happens, here is a workaround for PhoneGap/Cordova 3:

1. 在你的应用程序包创建一个子类 CordovaWebViewClient ：

public class SSLAcceptingCordovaWebViewClient extends CordovaWebViewClient {
    public SSLAcceptingCordovaWebViewClient(CordovaInterface cordova, CordovaWebView view) {
        super(cordova, view);
    }

    @Override
    public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
        handler.proceed();
    }
}

一样的 IceCreamCordovaWebViewClient ：

public class SSLAcceptingIceCreamCordovaWebViewClient extends IceCreamCordovaWebViewClient {
    public SSLAcceptingIceCreamCordovaWebViewClient(CordovaInterface cordova, CordovaWebView view) {
        super(cordova, view);
    }

    @Override
    public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
        handler.proceed();
    }
}

在＆lt;您的应用程序名称＆gt;的.java 添加替代的 makeWebViewClient ：

in <Your App Name>.java add an override for makeWebViewClient:

@Override
protected CordovaWebViewClient makeWebViewClient(CordovaWebView webView) {
    if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.HONEYCOMB) {
        return new SSLAcceptingCordovaWebViewClient(this, webView);
    } else {
        return new SSLAcceptingIceCreamCordovaWebViewClient(this, webView);
    }
}

等瞧！的SSL错误将被忽略。但是，切勿使用错误的证书。试着先解决这些问题，只有当您运行的其他解决方案使用这个肮脏的解决办法。

Et voilà! SSL errors will be disregarded. However, never use erroneous certificates. Try to fix them first and use this dirty workaround only when you run out of other solutions.
