Autenticação Leaflet Sem Login Individual

Question

Olá a todos,

Sou relativamente novo em programação e desenvolvimento de software, mas achei que este é o lugar para perguntar. Atualmente estou desenvolvendo um pequeno aplicativo para uso interno na minha empresa e estou travado na Autenticação Leaflet para acessar conteúdo de assinantes (uma camada do ArcGIS Online). Minha empresa tem um login de pessoal GIS para AGOL que eu gostaria de inserir no meu código JavaScript para que toda vez que alguém abrir o aplicativo, já esteja logado. Sou totalmente iniciante em JavaScript (esta é a primeira vez que uso) mas faz sentido até certo ponto.

Alguém pode me fornecer um trecho de código onde eu possa digitar as informações de login para que ele faça o login ao iniciar?

Obrigado pela ajuda!

Judson,

Did you end up finding a solution that worked well for you?  I'm working on a project with similar requirements.

Thanks,

the first and easiest option for displaying ArcGIS Online content in a Leaflet application that is not shared publicly is to embed credentials directly in your javascript and fetch a token automatically.  this is an EXTREMELY bad idea because you are exposing sensitive credentials in the code that is downloaded to each and every browser that ever opens your website.

L.esri.post('https://www.arcgis.com/sharing/rest/generateToken', {
  username: 'johndoe',
  password: 'password123',
  f: 'json',
  expiration: 60,
  client: 'referer',
  referer: window.location.origin
}, callback);

a second, more difficult, and more production appropriate option is to utilize a server side proxy to hide the username and password in code that is NOT accessible to your end users so that the proxy can broker requests to secure resources and append a token on its own.

L.esri.featureLayer({
  url: './proxy.ashx?http://services.arcgis.com/uasgdsgd/arcgis/rest/services/SelectivelyShared/FeatureServer/0'
}).addTo(map);

Open Source proxies in ASP.NET, PHP and Java that we host on GitHub

Some conceptual information from the ArcGIS API for JavaScript 3.x documentation

no matter what you do, you'll need to make sure you are honoring your license agreement and making sure the private content is only accessed by the number of ArcGIS Online named users you're paying for.
