Proble with org.grails.plugins:spring-security-facebook:0.17

[kikeseiya]

I have an application with:

• Grails 2.4.4

• org.grails.plugins:spring-security-facebook:0.17

• org.grails.plugins:spring-security-core:2.0.0

The application ran without problems, but these days I get this error:

ERROR facebook.FacebookAuthUtils - No access_token in response:
ERROR facebook.FacebookAuthUtils - No expires in response:
ERROR facebook.FacebookAuthUtils - Can't read data from Facebook
Message: Server returned HTTP response code: 400 for URL: https://graph.facebook.com/me?access_token=null

Any ideas please....

thank you

Enrique

[kikeseiya]

Hi, please upgrade to version 0.19 - author of this plugin already fix it there :-)

[kikeseiya]

Hi, doesn't work because facebook 0.19 only works with Grails 3.x and Spring-Security-Core plugin 3.x.

Mi application work with Grails 2.4.4 and Spring Security Source 2.0 :(

@kikeseiya hmm, maybe there is need to create fork ?

I modified the code with the new facebook format and it works.

`FacebookAccessToken requestAccessToken(String authUrl) {
try {
URL url = new URL(authUrl)
String response = url.readLines().first()
println "AccessToken response: $response"
println response.split(',')
Map data = [:]
int i = 0
response.split(',').each { String part ->
part = part.replace(""", "")
if (i == 0) {
part = part.substring(1)
}

			if (i == 2) {
				part = part.substring(0, part.length() - 1)
			}
			
			i++
			println part
            String[] kv = part.split(':')
            if (kv.length != 2) {
                log.warn("Invalid response part: $part")
            } else {
				println kv[0] + " " + kv[1]
                data[kv[0]] = kv[1]
            }
        }
        FacebookAccessToken token = new FacebookAccessToken()
        if (data.access_token) {
            token.accessToken = data.access_token
        } else {
            log.error("No access_token in response: $response")
        }
        if (data.expires_in) {
            if (data.expires_in =~ /^\d+$/) {
                token.expireAt = new Date(System.currentTimeMillis() + TimeUnit.SECONDS.toMillis(data.expires_in as Long))
            } else {
                log.warn("Invalid 'expires' value: $data.expires")
            }
        } else {
          log.error("No expires in response: $response")
        }
        //log.debug("Got AccessToken: $token")
        return token
    } catch (IOException e) {
        //TODO process error response
        log.warn("Can't read data from Facebook", e)
        return null
    }
