error OAuth [still have no clue]

[Guta Saputra]

hi all, im newbie/beginner in this section [OAuth things], i want to integrating my API access with OAuth [still dont know which version that i want to use] 

i read all about OAtuh recently, i found this good article about OAuth 1.0 version. 

http://phpmaster.com/creating-a-php-oauth-server/#comment-98172

i try to install it using composer but it goes to failed.

the error report is : 

package could not be downloaded, svn : E175002 : REPORT request on
‘/svb/!svn/vcc/default’
failed : 502 bad gateway

and then i go to this url [its writen on json.composer file] : http://oauth-php.googlecode.com/svn

and this is the documentation link : https://code.google.com/p/oauth-php/

i read both of them [the article + documentation] over and over again, but i still got no clue how to use it.

every time i try to see the example files, the error always comes up.

this time some error found in OAuthRequest.php on line 518 + 522.

the error reffer to Undefined index: scheme + host.

can you guys pls tell me how i remove those error and make it the source codes run.

PS : i ve curl installed on my local machine.
