HI ,

i am new to ROR

i am writing Ruby code for calling API blogs

i have written ruby code for

Creating the blog by

require ‘net/http’  
require ‘uri’

url = URI.parse(‘[http://localhost:3000/api/blogs/create.xml](http://localhost:3000/api/blogs/create.xml)’)  
req = Net::HTTP::Post.new(url.path)  
req.basic\_auth ‘a’, ‘a’  
req.set\_form\_data({‘blogpost[title]’=\>‘TestingAPIBlogposttitle’,  
‘blogpost[description]’=\>‘Testing api desc’,  
‘blogpost[category\_id]’=\>‘3121’}, ‘;’)  
res = Net::HTTP.new(url.host, url.port).start {|http| http.request(req)  
}  
case res  
when Net::HTTPSuccess, Net::HTTPRedirection  
puts res.body  
else  
res.error!  
end

which runs successfully by creating a new blog

And i have a search code

require ‘net/http’  
require ‘uri’  
require ‘cgi’

## Change this part according to the api to be accessed and the params

to be passed.  
uri = URI.parse( “[http://localhost:3000/api/blogs/show/blogtitle.xml](http://localhost:3000/api/blogs/show/blogtitle.xml)” )

### 

#blogtitle is the slug which is a mandatory , no other parameters

http = Net::HTTP.new(uri.host, uri.port)  
request = Net::HTTP::Get.new(uri.path)  
request.basic\_auth ‘a’, ‘a’  
response = http.request(request)

puts response.body

which returns the

\<?xml version="1.0" encoding="UTF-8"?\> 2010-09-02T08:18:22Z \<p\>Blog desc\</p\> blogtitle blogtitle admin knome admin 

Now i am trying to Update a BLog

for this how to write the code

i tried by simply changing the POST.new by PUT.new

but it didnt works for me

I tried by adding

require ‘net/http’  
require ‘uri’

url = URI.parse(‘[http://localhost:3000/api/blogs/update/blogtitle.xml](http://localhost:3000/api/blogs/update/blogtitle.xml)’)  
req = Net::HTTP::Put.new(url.path)  
req.basic\_auth ‘admin’, ‘admin’  
req.set\_form\_data({‘blogpost[title]’=\>‘TestingAPIBlogposttitle’,  
‘blogpost[description]’=\>‘Testing api desc’,  
‘blogpost[category\_id]’=\>‘379344121’}, ‘;’)  
res = Net::HTTP.new(url.host, url.port).start {|http| http.request(req)  
}  
case res  
when Net::HTTPSuccess, Net::HTTPRedirection  
puts res.body  
else  
res.error!  
end

but it shows me the 401 error even i gave the admin user credentials
