Question

我想在ruby中创建POST request。但是回去吧 #<Net::HTTPUnsupportedMediaType:0x007f94d396bb98>我尝试的是：

require 'rubygems'
require 'net/http'
require 'uri'
require 'json'

auto_index_nodes =URI('http://localhost:7474/db/data/index/node/')

request_nodes = Net::HTTP::Post.new(auto_index_nodes.request_uri)
http = Net::HTTP.new(auto_index_nodes.host, auto_index_nodes.port)

request_nodes.add_field("Accept", "application/json")

request_nodes.set_form_data({"name"=>"node_auto_index",
                            "config" => {
                            "type" => "fulltext",
                            "provider" =>"lucene"} ,
                            "Content-Type" => "application/json"
                            })


response = http.request(request_nodes)

试图写这部分：

"config" => {
             "type" => "fulltext",
             provider" =>"lucene"} ,
             "Content-Type" => "application/json"
            }

像那样：

"config" => '{
              "type" => "fulltext",\
              "provider" =>"lucene"},\
              "Content-Type" => "application/json"\
              }'

这个尝试也没有帮助：

request_nodes.set_form_data({"name"=>"node_auto_index",
                            "config" => '{ \
                            "type" : "fulltext",\
                            "provider" : "lucene"}' ,
                            "Content-Type" => "application/json"
                            })

试试这个：

require 'rubygems'
require "net/http"
require "uri"
require "json"

uri = URI.parse("http://localhost:7474/db/data/index/node/")

req = Net::HTTP::Post.new(uri.request_uri)
req['Content-Type'] = 'application/json'
req['Accept'] = 'application/json'

req.body = {
  "name" => "node_auto_index",
  "config" => { "type" => "fulltext", "provider" => "lucene" },
}.to_json    

res = Net::HTTP.start(uri.hostname, uri.port) do |http|
  http.request(req)
end

这是the API doc and a short introduction to Net::HTTP

Content-Type和Accept是标题，因此您需要将它们作为标题发送，而不是在正文中。 JSON内容应该放在请求正文中，但您需要将Hash转换为JSON，而不是将其作为名称/值对中的表单数据发送。

为什么我的http POST请求不顺利？
