SugarCRM: Getting "Invalid Session ID" error with REST calls

I'm using SugarCRM CE 6.0.3.

When I make REST API calls like get_entry_list(), I always get this error:

{'description': 'The session ID is invalid',
 'name':开发者_如何转开发 'Invalid Session ID',
 'number': 11}

I am very sure that I am logged in and using the correct session ID. In fact, when I can successfully call get_user_id() and retrieve my own user ID.

Googling has not produced any helpful results, anyone else encountered this problem?

I have found the problem, it is really just a matter of bad documentation on SugarCRM's part. The parameter naming is all wrong in this document:

http://developers.sugarcrm.com/docs/OS/6.0/-docs-Developer_Guides-Sugar_Developer_Guide_6.0-Chapter%202%20Application%20Framework.html#9000259

Simple fix for this problem: Do not use named parameters when making REST calls in SugarCRM. i.e. Use positional parameters (JSON array) for 'rest_data' in API calls.

I encountered this issue with the set_entry api call. For me the issue is one of the values that I was submitting to the call contained special characters that the api couldn't handle. My solution was to urlencode the value, and Sugar decodes it on their end. See below:

$name = "abc's ; 10/10/2013";
$values = array(
                "name"=>$name
          );
$sugar->set_entry("Accounts", $values);

The above threw the Invalid session ID error. Below is the code that works:

$name = urlencode("abc's ; 10/10/2013");
$values = array(
                "name"=>$name
          );
$sugar->set_entry("Accounts", $values);
