我无法使用
Ruby的HTTParty库向API端点发送POST请求.我正在与之互动的API是
Gittip API,其端点需要身份验证.我已经能够使用HTTParty成功地进行身份验证的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 } })
该请求的作用并按预期返回以下内容：
[
{
"amount" => "1.00","platform" => "gittip","username" => "whit537"
},{
"amount" => "0.25","username" => "JohnKellyFerguson"
}
]
但是,我无法使用HTTParty成功发送POST请求. Gittip API描述了使用curl进行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"
我尝试(不成功)使用HTTParty构造我的代码,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","username" => "whit537" } ],:basic_auth => { :username => api_key },:headers => { 'Content-Type' => 'application/json' }
})
第一个参数是url,第二个参数是一个选项哈希.当我运行上面的代码,我得到以下错误：
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'
我已经尝试了各种其他的结构化API调用的组合,但是无法弄清楚如何使其工作.这是另一个这样的例子,我不会将数组用作body的一部分,并将内容转换为_json.
user = "gratitude_test"
api_key = "5962b93a-5bf7-4cb6-ae6f-aa4114c5e4f2"
HTTParty.post("https://www.gittip.com/#{user}/tips.json",{
:body => { "amount" => "0.25","username" => "whit537" }.to_json,:headers => { 'Content-Type' => 'application/json' }
})
哪个返回以下(一个500错误)：
<html>
<head>
<title>500 Internal Server Error</title>
</head>
<body>\n Internal server error,program!\n <pre></pre>
</body>
</html>
我不是很熟悉卷曲,所以我不知道我是否错误地将东西翻译成HTTParty.
任何帮助将不胜感激.谢谢.
解决方法
只是一个猜测,但是看起来你希望在JSON中传递散列.
尝试用以下代替：body声明：
:body => [{ "amount" => "0.25","username" => "whit537" }].to_json
编辑：
我建议使用to_json序列化程序,但是将其放在哈希而不是数组之后,将其放在一起,并将其完全删除.该示例使用多个记录,因此阵列是必需的.
看着this thread后,看起来Gittip对于接受标题很挑剔.
:headers => { 'Content-Type' => 'application/json','Accept' => 'application/json'}
所以,完整的建议是：
HTTParty.post("https://www.gittip.com/#{user}/tips.json",{
:body => [ { "amount" => "0.25","username" => "whit537" } ].to_json,:headers => { 'Content-Type' => 'application/json','Accept' => 'application/json'}
})
