Ruby undefined method `bytesize' for #

Question

i have the following Ruby Code, for a tracking website in sandbox mode: ``` require "net/http" require "net/https" require "uri" xml = < XML uri = URI('https://cig.dhl.de/services/sandbox/rest/sendungsverfolgung') nhttp = Net::HTTP.new(uri.host, uri.port) nhttp.use_ssl=true nhttp.verify_mode=OpenSSL::SSL::VERIFY_NONE request = Net::HTTP::Get.new(uri) request.basic_auth 'xpackageWP', 'hidden' response = nhttp.start {|http| http.request(request, xml:xml) } puts response.body ``` I always get the error : ``` d:/Ruby200/lib/ruby/2.0.0/net/http/generic_request.rb:179:in `send_request_with_body' undefined method `bytesize' for # (NoMethodError) from d:/Ruby200/lib/ruby/2.0.0/net/http/generic_request.rb:130:in `exec' from d:/Ruby200/lib/ruby/2.0.0/n…

Accepted Answer

You're sending post data as a hash. You should encode it as string.

For example Using `URI::encode_www_form`:

```
request = Net::HTTP::Post.new(uri)
...
response = nhttp.start do |http|
  post_data = URI.encode_www_form({xml: xml})
  http.request(request, post_data)
end
```

UPDATE If you want GET request, append the query string to the url.

```
post_data = URI.encode_www_form({xml: xml})
uri = URI('https://cig.dhl.de/services/sandbox/rest/sendungsverfolgung?' +
          post_data)

...

response = nhttp.start do |http|
  http.request(request)
end
```
