Question

我使用HTTParty从api获取数据。我设法恢复了XML响应，看起来HTTParty已经将xml响应变成了Ruby。

如何浏览哈希值并获取所需的数据？例如，假设我想要“名称”，即“第29个AVENUE STN / ARBUTUS”。

API密钥工作正常，因为我收到了回复。

我不太确定如何浏览并获取我想要的数据，并将其放入我的视图中。

index.html.erb：

public function handle(Request $request, $url)
{
    // logic to search and render your vanity page for $url

    // if no vanity page was found:
    throw new \Symfony\Component\HttpKernel\Exception\NotFoundHttpException();
}

HTTparty回复：

<% @courses.each do |course| %>
<%= course %>

<% end %>

        }, "Direction" => "EAST"

假设您有回复：

resp = ["Route", {
"RouteNo" => "016", "Name" => "29TH AVENUE STN/ARBUTUS ", "OperatingCompany" => "CMBC", "Patterns" => {
    "Pattern" => [{
        "PatternNo" => "E5TP", "Destination" => "29TH AVE STN", "RouteMap" => {
            "Href" => "http://nb.translink.ca/geodata/trip/016-E5TP.kmz"
        }, "Direction" => "EAST"
    }, {
        "PatternNo" => "EB1", "Destination" => "29TH AVE STN", "RouteMap" => {
            "Href" => "http://nb.translink.ca/geodata/trip/016-EB1.kmz"
        }, "Direction" => "EAST"
    }, {
        "PatternNo" => "EB5", "Destination" => "29TH AVE STN", "RouteMap" => {
            "Href" => "http://nb.translink.ca/geodata/trip/016-EB5.kmz"
        }, "Direction" => "EAST"
    }]
}
}]

又是两个元素的数组，首先是＆＃39; Route＆＃39;并且最后一个是具有所有属性的哈希，以简单地使用名称：

resp.last['Name']
