我很难使用 Ruby 的 HTTParty 库向 API 端点发出 POST 请求。我正在与之交互的 API 是Gittip API,它们的端点需要身份验证。我已经能够使用 HTTParty 成功发出经过身份验证的 GET 请求。
您可以在示例代码中看到:
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 } })
该请求有效并按预期返回以下内容:
[
{
"amount" => "1.00",
"platform" => "gittip",
"username" => "whit537"
},
{
"amount" => "0.25",
"platform" => "gittip",
"username" => "JohnKellyFerguson"
}
]
但是,我一直无法使用 HTTParty 发出成功的 POST 请求。Gittip API 描述了使用 curl 发出 POST 请求,如下所示:
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"
我已经尝试(不成功)使用 HTTParty 构建我的代码,如下所示:
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' }
})
第一个参数是 url,第二个参数是选项哈希。当我运行上面的代码时,我收到以下错误:
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'
我尝试了各种其他组合 API 调用的结构,但不知道如何让它工作。这是另一个这样的例子,我不使用数组作为正文的一部分并转换内容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' }
})
它返回以下内容(500 错误):
<html>
<head>
<title>500 Internal Server Error</title>
</head>
<body>\n Internal server error, program!\n <pre></pre>
</body>
</html>
我对 curl 不是很熟悉,所以我不确定我是否错误地将内容转换为 HTTParty。
任何帮助,将不胜感激。谢谢。
