using HTTP, JSON

기본정보

client_id = "xxxxxxxxxx"
client_secret = "xxxxxxxxxx"
username = "userid"
password = "userpw"
api_token = "https://auth.xxxx.xxxx/auth/v1/token"

api_host = "https://api.xxxx.xxxx/v1"
api_campaign = "/campaigns"

"/campaigns"

Get Access Token Function

function get_access_token(url::String,
                           client_id::String, client_secret::String,
                           username::String, password::String)::String
  u = HTTP.URIs.URI(url)
  uri = HTTP.URIs.URI(;scheme=u.scheme,
              userinfo=client_id*":"*client_secret,
              host=u.host,
              path=u.path)
  headers = [ 
    "Accept" => "application/json",
    "Content-Type" => "application/x-www-form-urlencoded"
  ]
  query_dict = [
    "grant_type" => "password", 
    "username" => username, 
    "password" => password,
    "scope" => "openid"]
  body = HTTP.escapeuri(query_dict)

  r = HTTP.request("POST",uri,headers,body)
  j =JSON.parse(String(r.body))
  return j["access_token"]
end

get_access_token() = get_access_token(api_token,client_id,client_secret,username,password)

Get data function

function get_data(api::String,params::Dict)
  url = api_host*api
  u = HTTP.URIs.URI(url)
  uri = HTTP.URIs.URI(;scheme=u.scheme,
              host=u.host,

  ]
  body = HTTP.escapeuri(params)
  try
    r = HTTP.request("GET",uri,headers,body)
    j =JSON.parse(String(r.body))
    if haskey(j,"result") && haskey(j,"data")

    #println(fieldnames(typeof(e)))
    #println(fieldnames(typeof(e.response)))

캠페인 목록 조회

(result, data)

camp_lst = get_data(api_campaign,Dict([]))

URL:https://api.xxxx.xxxx/v1/campaigns

Dict{String,Any} with 2 entries:
  "document"   => Dict{String,Any}("campaignDc"=>"캠페인 등록 테스트","campaign…
  "resourceId" => 26

resourceId = Int(floor(rand()*length(camp_lst[2])))
println(camp_lst[2][resourceId])

Dict{String,Any}("document" => Dict{String,Any}("campaignDc" => "캠페인 등록 테스트","campaignSn" => 82,"donateEndDate" => "20211231","optInfo" => "{}","campaignName" => "테스트","campaignType" => "02","goalDonateAmount" => 100000000,"donateBeginDate" => "20210311"),"resourceId" => 26)

캠페인 상세 조회
