I am having difficulty making a POST request to an API endpoint using Ruby's HTTParty library. The API I'm interacting with is the Gittip API and their endpoint requires authentication. I have been able to successfully make an authenticated GET request using HTTParty.
You can see in the example code:
user = "gratitude_test"
api_key = "5962b93a-5bf7-4cb6-ae6f-aa4114c5e4f2"
# I have included real credentials since the above is merely a test account.
HTTParty.get("https://www.gittip.com/#{user}/tips.json",
{ :basic_auth => { :username => api_key } })
That request works and returns the following as expected:
[
{
"amount" => "1.00",
"platform" => "gittip",
"username" => "whit537"
},
{
"amount" => "0.25",
"platform" => "gittip",
"username" => "JohnKellyFerguson"
}
]
However, I have been unable to make a successful POST request using HTTParty. The Gittip API describes making a POST request using curl as follows:
curl https://www.gittip.com/foobar/tips.json
-u API_KEY:
-X POST
-d'[{"username":"bazbuz", "platform":"gittip", "amount": "1.00"}]'
-H"Content-Type: application/json"
I have tried (unsuccessfully) structuring my code using HTTParty as follows:
user = "gratitude_test"
api_key = "5962b93a-5bf7-4cb6-ae6f-aa4114c5e4f2"
HTTParty.post("https://www.gittip.com/#{user}/tips.json",
{
:body => [ { "amount" => "0.25", "platform" => "gittip", "username" => "whit537" } ],
:basic_auth => { :username => api_key },
:headers => { 'Content-Type' => 'application/json' }
})
The first argument is the url and the second argument is an options hash. When I run the code above, I get the following error:
NoMethodError: undefined method `bytesize' for [{"amount"=>"0.25", "platform"=>"gittip", "username"=>"whit537"}]:Array
from /Users/John/.rvm/rubies/ruby-2.0.0-p247/lib/ruby/2.0.0/net/http/generic_request.rb:179:in `send_request_with_body'
I have tried various other combinations of structuring the API call, but can't figure out how to get it to work. Here's another such example, where I do not user an array as part of the body and convert the contents to_json.
user = "gratitude_test"
api_key = "5962b93a-5bf7-4cb6-ae6f-aa4114c5e4f2"
HTTParty.post("https://www.gittip.com/#{user}/tips.json",
{
:body => { "amount" => "0.25", "platform" => "gittip", "username" => "whit537" }.to_json,
:basic_auth => { :username => api_key },
:headers => { 'Content-Type' => 'application/json' }
})
Which returns the following (a 500 error):
<html>
<head>
<title>500 Internal Server Error</title>
</head>
<body>
Internal server error, program!
<pre></pre>
</body>
</html>
I'm not really familiar with curl, so I'm not sure if I am incorrectly translating things to HTTParty.
Any help would be appreciated. Thanks.
