用heroku部署蒸气

幼稚的

我创建了一个非常简单的应用程序,其中包含一条路线main.swift它从查询字符串中读取城市,并使用它来获取该城市的天气(通过yahoo API)。这是路线:

drop.get("whether") { request in


    guard let city = request.data["city"]?.string else {
        return try JSON(node: ["Error": "no city given"])
    }

    return try drop.client.get("https://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20weather.forecast%20where%20woeid%20in%20(select%20woeid%20from%20geo.places(1)%20where%20text%3D%22\(city)%22)&format=json&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys")
}

当我在localhost上运行该代码时,它可以完美运行,但是在将其与Heroku一起部署时,出现500错误。

是否有我不应该推送到heroku的文件?我要指出的是,server.json主机值是0.0.0.0

这是我的Heroku日志(请注意,我已对其进行了多次重新部署。所有这些都不起作用):

Slack频道中的一个用户使我了解了这个问题。

VZSG:@animatronicgopher:在Heroku上进行实验很便宜,但是正因为如此,扩大到付费测功机是毫无意义的。它并不能有所作为-首先,通过一个HTTP产生这个错误的客户端,让您的服务器的证书并不重要,和第二,甚至是免费的DYNOS有适当的证书(和他们不只是letsencrypt证书其一)。您可能发现的是自定义域。

实际问题是“默认” HTTPClient不关心dyno的受信任根证书,因此无法验证传出SSL连接->错误。

此外,GitHub中存在一个问题,该问题为您提供了如何使用FoundationClient的示例。https://github.com/vapor/vapor/issues/699
