我在node.js应用程序中实现Oauth2身份验证时遇到问题，我需要在授权请求中添加一个额外的参数，但是该模块只是忽略了“未知”参数。

我的代码附在下面。被忽略的参数是APIName。

var OAuth2Strategy = require('passport-oauth2').Strategy;

// load the auth variables
var configAuth = require('./auth');

module.exports = function(passport) {

    passport.use('ihealth', new OAuth2Strategy({
            authorizationURL: 'https://api.ihealthlabs.com:8443/OpenApiV2/OAuthv2/userauthorization/',
            tokenURL: 'https://api.ihealthlabs.com:8443/OpenApiV2/OAuthv2/userauthorization/',
            clientID: configAuth.iHealthAuth.clientID,
            clientSecret: configAuth.iHealthAuth.clientSecret,
            callbackURL: configAuth.iHealthAuth.callbackURL,
            APIName : 'OpenApiActivity'
        },
        function(token, refreshToken, profile, done) {

            // ...

        }
    ));
};

我知道APIName被忽略的原因是，我在浏览器中看到该URL：

https://api.ihealthlabs.com:8443/OpenApiV2/OAuthv2/userauthorization/?response_type=code&redirect_uri=SOMEREDIRECTURI&client_id=SOMECLIENTID

我想知道如何启用向授权请求中添加其他参数？也许通过重写功能OAuth2Strategy.prototype.authorizationParams中node_modules/passport_oauth2/lib/strategy.js，它看起来像这样在donwloaded文件：

/**
 * Return extra parameters to be included in the authorization request.

 * Some OAuth 2.0 providers allow additional, non-standard parameters to …
