我正在创建一个使用外部地理定位API的小型Rails。它应该采用字符串(地址)并返回坐标。我不知道如何使用HTTParty gem设置基URI。 API的文档说请求可以发送到端点
GET https://eu1.locationiq.com/v1/search.php?key=YOUR_PRIVATE_TOKEN&q=SEARCH_STRING&format=json
如何在我的类方法中设置标记和搜索字符串?这是我到目前为止的代码。
locationiq_api.rb
include HTTParty
base_uri "https://eu1.locationiq.com/v1/search.php?key=pk.29313e52bff0240b650bb0573332121e&q=SEARCH_STRING&format=json"
attr_accessor :street
def find_coordinates(street)
self.class.get("/locations", query: { q: street })
end
def handle_error
if find_coordinates.code.to_i = 200
find_coordinates.parsed_response
else
raise "Couldn't connect to LocationIQ Api"
end
end
end```
locations controller:
```class LocationsController < ApplicationController
before_action :find_location, only: [:show, :destroy, :edit, :update]
def new
@search = []
# returns an array of hashes
@search = locationiq_api.new.find_coordinates(params[:q])['results'] unless params[:q].nil?
end
def create
@location = Location.new(location_params)
if @location.save
redirect_to root_path
else
render 'new'
end
end
private
def location_params
params.require(:location).permit(:place_name, :coordinate)
end
def find_location
@location = Location.find(params[:id])
end
end```
这样的事情可能会有所帮助:
class LocationIqApi
include HTTParty
base_uri "https://eu1.locationiq.com/v1/search.php"
def initialize(api_key, format = "json")
@options = { key: api_key, format: format }
end
def find_coordinates(street)
self.class.get("/locations", query: @options.merge({ q: street }))
end
def handle_error
if find_coordinates.code.to_i = 200
find_coordinates.parsed_response
else
raise "Couldn't connect to LocationIQ Api"
end
end
end
然后,当您想要使用它时,您需要使用您的密钥创建一个新实例:
@search = LocationIqApi.new(YOUR_API_KEY_HERE).find_coordinates(params[:q])
