InvalidURIError making request to Facebook Graph API with Ruby -


i'm trying response api includes fields i'm specifying in uri string keep receiving invalidurierror. i've come here last resort, having spent hours trying debug this. i've tried using uri.encode() method on well, same error.

here's code:

url = params[:url] uri = uri('https://graph.facebook.com/v2.3/?id=' + url + '&fields=share,og_object{id,url,engagement}&access_token=' + config['fb_access_token']) req = net::http::post.new(uri.path) req.set_form_data('fields' => 'og_object[engagement]','access_token' => config['fb_access_token'])  res = net::http.new(uri.host, uri.port) res.verify_mode = openssl::ssl::verify_none res.use_ssl = true  response = nil res.start |http|     response = http.request(req) end  response = http.request(req)  output = "" output << "#{response.body} <br />" return output

and error i'm receiving:

uri::invalidurierror - bad uri(is not uri?): https://graph.facebook.com/v2.3/?id=http://www.wikipedia.org&fields=share,og_object{id,url,engagement}&access_token=960606020650536|ejc0pocarfaqkzwzhdwn5ogkhfs

i'm exhausted @ point if left out important information let me know , i'll respond can. thank you!

the problem you're dumping strings uri without escaping them first.

since you're using sinatra can use rack::utils.build_query construct uri's query component values correctly escaped:

uri = uri('https://graph.facebook.com/v2.3/') uri.query = rack::utils.build_query(   id: url,   fields: 'share,og_object{id,url,engagement}',   access_token: config['fb_access_token'] )

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
