使用Linkedin API时出现400错误的请求

Question

From LinkedIn developer forum thread I downloaded this sample: LinkedInAuth.rar.zip, it works.

When I use:

string response = _oauth.APIWebRequest(
    "GET",
    "http://api.linkedin.com/v1/people/~/group-memberships:(group:(id,name,counts-by-category))?membership-state=member",
     null);

It returns all groups.

But when I use:

string response = _oauth.APIWebRequest(
    "GET",
    "http://api.linkedin.com/v1/groups/{2139884}/posts:(creation-timestamp,title,summary,creator:(first-name,last-name,picture-url,headline),likes,attachment:(image-url,content-domain,content-url,title,summary),relation-to-viewer)?category=discussion&order=recency&modified-since=1302727083000&count=5",
    null);`

It returns the error:

400 bad request

I used a groups id hard-coded which exist and return by 1st. I tried to follow the documentation . Anyone face this problem before or I am missing something.

Answer 1

Double check your server time. I experienced the same the issue before I changed it (the issue started to happen after the summer time change).

Answer 2

You don't need the curly braces around the ID. The curly braces indicate that you're going to put a variable there. Try:

http://api.linkedin.com/v1/groups/{2139884}/posts:(creation-timestamp,title,summary,creator:(first-name,last-name,picture-url,headline),likes,attachment:(image-url,content-domain,content-url,title,summary),relation-to-viewer)?category=discussion&order=recency&modified-since=1302727083000&count=5
