blocks|key|1724279|text|所以，我把链接粘贴到我电脑上的Chrome上，OAuth程序运行得很好。我注意到按钮一开始是灰色的，但后来变成了明亮的绿色。这让我想知道:默认情况下，JavaScript是否在安卓WebView中启用？当然，事实并非如此。我找到了这个答案，它详细说明了如何启用JS。这是让一切正常运转的关键路线：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1724280|webView.getSettings().setJavaScriptEnabled(true);|code-block|syntax|javascript|1724281|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/5089694/4077294^0|37|4|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@$A|R|B|S|1|T]]|C|$]]|$1|D|3|E|5|F|7|U|8|@]|9|@]|C|$G|H]]|$1|I|3|-4|5|6|7|V|8|@]|9|@]|C|$]]]|J|$K|$5|L|M|N|C|$O|P]]]]

So, I pasted the link into Chrome on my computer and the OAuth process worked fine. I noticed the button was greyed out at first, but then became bright green. This got me wondering: was JavaScript enabled by default in the Android WebView? Sure enough, it wasn't. I found <a href="https://stackoverflow.com/a/5089694/4077294">this answer</a> which details how to enable JS. This was the key line that got everything working:

<pre><code>webView.getSettings().setJavaScriptEnabled(true);
</code></pre>

blocks|key|385769|text|我绝对支持@james所说的-+JS必须为WebView启用。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|385770|但有时也没什么用。我发现了一些更多的信息，我很乐意在这里分享。|385771|类似的故事-我有一个应用程序，应该用GitHub+OAuth登录用户，一切正常运行，除了“授权”按钮-它只是保持禁用，无论应用的设置是一些情况。|385772|以下是总结：|385773|无论设置和用户行为如何，该按钮在API+22和23的模拟器上始终处于禁用状态(我没有尝试24-27+)。|ordered-list-item|385774|它在API+28和29的仿真器上运行良好。|385775|在真正的设备像素3+(API+29)上，按钮最初是被禁用的，有一段时间什么也没有发生。但是当我在随机的地方录下屏幕两次时，它就启用了。该应用程序重新启动的情况再现:最初禁用按钮->点击屏幕->按钮被启用。|385776|很明显涉及到一些反欺诈机制。|385777|但是它给最终用户提供了一些糟糕的体验，它看起来像是应用程序中的一个bug，我们对它无能为力:-/|385778|entityMap^0|G|C|0|0|0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@$9|Z|A|10|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|11|8|@]|D|@]|E|$]]|$1|H|3|I|5|6|7|12|8|@]|D|@]|E|$]]|$1|J|3|K|5|6|7|13|8|@]|D|@]|E|$]]|$1|L|3|M|5|N|7|14|8|@]|D|@]|E|$]]|$1|O|3|P|5|N|7|15|8|@]|D|@]|E|$]]|$1|Q|3|R|5|N|7|16|8|@]|D|@]|E|$]]|$1|S|3|T|5|6|7|17|8|@]|D|@]|E|$]]|$1|U|3|V|5|6|7|18|8|@]|D|@]|E|$]]|$1|W|3|-4|5|6|7|19|8|@]|D|@]|E|$]]]|X|$]]

I absolutely support what @james-ko said - JS has to be enabled for the WebView.

But sometimes it doesn't help. I found a little bit more info and would be happy to share it here. 

Similar story - I have an app which is supposed to login the user with GitHub OAuth, everything works fine except the "Authorise" button - it just stays disabled whatever setting were applied is some cases.

Here is summary: 

<ol>
<li>The button is always stays disabled on emulator with API 22 and 23 (I didn't try 24-27 though) regardless of settings and user behaviour.</li>
<li>It works well on emulator with API 28 and 29.</li>
<li>On the real device Pixel 3 (API 29), the button was disabled initially and nothing was happening for a while. But when I taped the screen twice in random places it got enabled. The app restarting reproduces the situation: initially disabled button --> tap on the screen --> button gets enabled.</li>
</ol>

Apparently some antifraud mechanism is involved. 

But it gives kinda poor experience to the final user it looks like a bug in the app and there is not much what we can do about it :-/

blocks|key|1724401|text|我在Safari中也有同样的问题，但是我发现了一个潜在的原因，站点的内容安全策略被设置为：script-src+github.githubassets.com。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1724402|entityMap^0|19|Y|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

I had the same problem in Safari, but I located a potential cause, the content security policy of the site was set to: <code>script-src github.githubassets.com</code>

I am building an Android app that signs in users to GitHub using OAuth. I followed the instructions <a href="https://developer.github.com/v3/guides/basics-of-authentication/" rel="noreferrer">here</a> to do so. As the first part of the process, I sent users to the URL

<pre><code>https://github.com/login/oauth/authorize?scope=repo&amp;client_id=MY_CLIENT_ID
</code></pre>

However, when I sign in on my Android device, the <code>Authorize xxxx</code> button appears to be greyed out and I can't click it. Does anyone have a clue why this is? (Large screenshot below)

I think the button may not have been greyed out before, the first time I ran the app and signed in. However, I can't tell for sure because I was in a rush.

Why is the GitHub authorization button in the OAuth flow grayed out?
