TwitterTemplate Friendship Functionality

[garyj]

Hi All

Just wondering if there are plans to implement the friendship functionality in the TwitterTemplate. For example friendships/create, friendships/destroy etc.

Also if I was to start adding that functionality to the TwitterTemplate, should I look into submitting patches back into Spring Social?

Gary,
See http://blog.springsource.com/2010/12...ring-projects/ for contribution guidelines. We recently received a merge request for additions to FacebookTemplate and are reviewing that for integration as we speak.

Hi Guys

So I'm working on the follow/unfollow functionality and am currently in the middle of testing the code. I used the apigee console to simulate a follow POST as follows:

http://api.twitter.com/1/friendships/create.json?screen_name=oizik2

and received the following response

{
"favourites_count" : 0,
"friends_count" : 2,
"profile_background_color" : "C0DEED",
"url" : null,
"profile_background_image_url" : "http://a3.twimg.com/a/1297708673/images/themes/theme1/bg.png",
"description" : null,
"screen_name" : "oizik2",
"status": {
"in_reply_to_status_id_str" : null,
"in_reply_to_user_id" : null,
"text" : "woohoo my twitter application is still working!!! ",
"contributors" : null,
"retweeted" : false,
"in_reply_to_user_id_str" : null,
"retweet_count" : 0,
"geo" : null,
"source" : <a href='http://www.ipeg.com.au' rel='nofollow'>iPeg - Test</a>,
"created_at" : "Tue Feb 01 09:35:27 +0000 2011",
"id_str" : "32371442398007296",
"place" : null,
"in_reply_to_status_id" : null,
"coordinates" : null,
"truncated" : false,
"favorited" : false,
"id" : 32371442398007296,
"in_reply_to_screen_name" : null
},
"verified" : false,
"location" : null,
"listed_count" : 0,
"time_zone" : null,
"profile_text_color" : "333333",
"lang" : "en",
"notifications" : false,
"created_at" : "Fri Jan 14 08:00:25 +0000 2011",
"profile_sidebar_fill_color" : "DDEEF6",
"id_str" : "238061111",
"show_all_inline_media" : false,
"geo_enabled" : false,
"profile_background_tile" : false,
"followers_count" : 1,
"profile_link_color" : "0084B4",
"protected" : false,
"statuses_count" : 7,
"profile_sidebar_border_color" : "C0DEED",
"name" : "Gary Jarrel",
"is_translator" : false,
"contributors_enabled" : false,
"following" : true,
"id" : 238061111,
"follow_request_sent" : false,
"profile_use_background_image" : true,
"utc_offset" : null,
"profile_image_url" : "http://a2.twimg.com/sticky/default_profile_images/default_profile_1_normal.png"
}


This is one of my Twitter testing accounts.

I then used the entire response in the follow.json file which and subsequently used it in my test case with the mockServer ... andRespond(withResponse(new ClassPathResource("follow.json", getClass()), responseHeaders));

The problem is effectively with the returned JSON data and the line "source" : <a href='http://www.ipeg.com.au' rel='nofollow'>iPeg - Test</a>, notice how the URL is not quoted and this cause Jackson to fail with the following exception

org.springframework.http.converter.HttpMessageNotR eadableException: Could not read JSON: Unexpected character ('<' (code 60)): expected a valid value (number, String, array, object, 'true', 'false' or 'null')

.......

When I manually put the quotes around the URL then it works fine, however with the actual Twitter response it fails on the < character.

Is there a way to tell Jackson to treat this as a String perhaps, or add an exception to allow parsing such data?

Or perhaps I should go to the Jackson mailing list?

Cheers,

Gary

Please ignore my post above, I was using the response from apigee console, when I used the Twurl console the response was formatted correctly.
