facebook登录没有sdk

Question

我想在oauth2流程之后使用Facebook对用户进行身份验证。

我想在不使用SDK的情况下这样做。但我无法理解用户oauth身份验证的端点是什么。

我在哪里可以找到它们？

编辑。这是在移动应用程序中。 IOS或android。

Answer 1

您可以在Developer docs中找到此信息：

• https://developers.facebook.com/docs/facebook-login/manually-build-a-login-flow/v2.3
• https://developers.facebook.com/docs/facebook-login/access-tokens#usertokens

Answer 2

这是我的Android（java）登录。

    APP_ID = "XXXXXXXXXXXXXXXX"
    RAW_REDIRECT_URI = "https://www.facebook.com/connect/login_success.html";

    // UTF8 adress so it can go along the http request
    REDIRECT_URI ="";
    try {
         REDIRECT_URI = URLEncoder.encode(RAW_REDIRECT_URI, "UTF-8");
    } catch (UnsupportedEncodingException e) {
         e.printStackTrace();
    }

    // get the code or token
    TOKEN_REQUEST = "https://www.facebook.com/v3.2/dialog/oauth?client_id="+APP_ID+"&redirect_uri="+REDIRECT_URI+ "&state=\'{st=state123abc,ds=123456789}\'";


    // start WebView
    webView.setWebViewClient(new WebViewClient() {
        // shouldOverride will run each time a new URL is loaded in the webview.
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            // the loaded URL is our redirect URL
            if(url.startsWith(RAW_REDIRECT_URI)) {
                // here you have two choices...
                // - make a call to your private server to get the token from the code (recommended)
                // - make the API requests because you added a response_type=token in the TOKEN_REQUEST (less secure ) 
            }
            return false;
        }
    });


    // javascript doesn't seem to be needed for facebook but for instagram yes.
    webView.getSettings().setJavaScriptEnabled(true);
    webView.loadUrl(TOKEN_REQUEST);
