ajax - How to post to external url from rails app without using form -


i able post payment gateway using html form. got new requirement. now, on click of "payment" button, have validate whether item still available purchase , if available automatically post payment form gateway.

so say, want execute rails controller code on button click , want redirect external url ( payment gateway ) params if validation succeed.

i read, not possible post using redirect_to in rails. not possible post using ajax external url. how should achieve ?

you can use ruby’s net::http this:

require "net/http" require "uri"  uri = uri.parse("http://example.com/search") params = {"foo" => "value one", "bar" => "value two"}   # shortcut way response = net::http.post_form(uri, params)   # more control http = net::http.new(uri.host, uri.port) request = net::http::post.new(uri.request_uri) request.set_form_data(params) response = http.request(request)   puts response.code             # => 200 puts response.body             # => body (html, json, etc)

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 ...
