ruby-on-rails - x-www-form-urlencoded POST 请求和 net/http 上缺少查询参数

Question

我有一个带有 header 和查询参数的发布请求，我想用 net/http 触发。请求返回 200，但响应正文显示:{\"error\":\"invalid_request\",\"error_description\":\"Required query parameter 'grant_type' missing.\"}

这是我调用的完整函数:

def Search.request_oauth_access_token
    require 'net/http'
    uri = URI.parse('https://request.url/oauth2/access_token')
    params = {
        'grant_type' => 'my:grant:type'
    }
    headers = {
    'Authorization' => 'Basic sldhfgKGsdfgGOI23==',
    'Content-Type' => 'application/x-www-form-urlencoded'
    }
    http = Net::HTTP.new(uri.host, uri.port)
    http.use_ssl = true
    request = Net::HTTP::Post.new(uri.request_uri, headers)
    query = URI.encode_www_form_component(params)
    request.body = query
    response = http.request(request)
    p response.body
end

我正在使用 Rails 5.0.2。

解决了。原来我在 params 定义中有一个语法错误。这是定义它的正确方法:

params = {
        grant_type: 'my:grant:type'
    }

然后在请求中:

query = URI.encode_www_form(params)
http.request(request, query)
