I have an app in my salesforce developer account that I want to allow my users to access from a remote app that I am building. I see that I must use OAuth2.0 to first authorize my users before they are allowed to access the salesforce data. At the moment I am trying to use the username-password OAuth flow described on salesforce.
Step 1) I request an access token using username and password via the below code snippet
var password = 'userPassword' + 'securityToken'
$.ajax({
type: 'GET',
url: 'https://login.salesforce.com/services/oauth2/token',
contentType: 'application/json',
dataType: 'json',
beforeSend: function(xhr) {
xhr.setRequestHeader('grant_type','password'),
xhr.setRequestHeader('client_id', '<client_id_here>'),
xhr.setRequestHeader('client_secret', '<client_secret_here'),
xhr.setRequestHeader('username', '[email protected]'),
xhr.setRequestHeader('password', "password")
},
success: function(response) {
console.log('Successfully retrieved ' + response);
//Other logic here
},
error: function(response) {
console.log('Failed ' + response.status + ' ' + response.statusText);
//Other logic here
}
});
My request, however, is failing with the following message:
1) OPTIONS https://login.salesforce.com/services/oauth2/token 400 (Bad Request)
2) XMLHttpRequest cannot load https://login.salesforce.com/services/oauth2/token. No
'Access-Control-Allow-Origin' header is present on the requested resource.
Origin http://localhost is therefore not allowed access.
I have seen some sources (here here here) mention that CORS is not supported in salesforce and that another solution should be used. Some solutions I have seen are Salesforce APEX code, AJAX toolkit, or ForceTK.
In summary, I am looking to see if (1) there is a simple mistake that I am making with my above request to get the OAuth access_token (2) or if I need to do something different to get the access (3) is there a better way to log in users and access their salesforce data from my connected app?
All and any help is appreciated!
