How to send String Variables in the HTTP request instead of actual values?

Hello, 

 

Currently, the code for my HTTPRequest looks like this and it works perfectly!

 

String strBody ='grant_type=password
& client_id=3MVG9A2kN3Bn17htdoBkg4rhC3s7_2.RuejWu40cERuwe9wW7zVaPZ.rSmqCjv0x_hbmqHim8dIEg
&client_secret=581611111111111111
&username=username@gmail.com
&password=mypassword1234vU13GM4JKSA5tVCh8UIlrNec7';

 Http http = new Http();

 HttpRequest req = new HttpRequest();
 req.setBody(strBody);
 req.setMethod('POST');
 req.setEndpoint('https://login.database.com/services/oauth2/token');

 

But when I put my username and password in string variables, and pass those variable in the requestbody, as follows,

String uname = 'username@gmail.com';

String pword = 'mypassword1234vU13GM4JKSA5tVCh8UIlrNec7';

String strBody ='grant_type=password
& client_id=3MVG9A2kN3Bn17htdoBkg4rhC3s7_2.RuejWu40cERuwe9wW7zVaPZ.rSmqCjv0x_hbmqHim8dIEg
&client_secret=581611111111111111
&username=uname
&password=pword';,

 

throws

 

error":"unsupported_grant_type","error_description":"grant type not supported

I am looking for a way where I can dynamically send the parameters.

 

Please help.

It has a very simple solution.

String uname = 'username@gmail.com';

String pword = 'mypassword1234vU13GM4JKSA5tVCh8UIlrNec7';

String strBody ='grant_type=password
& client_id=3MVG9A2kN3Bn17htdoBkg4rhC3s7_2.RuejWu40cERuwe9wW7zVaPZ.rSmqCjv0x_hbmqHim8dIEg
&client_secret=581611111111111111
&username='+uname+'
&password='+pword+'';

 

If you put the variable in '+ +', it will be read as a variable.
