用heroku部署Vapor

Question

我在main.swift中创建了一个非常简单的应用程序，只有一条路径。它从查询字符串中读取一个城市，并使用它获取该城市的天气(通过yahoo )。这就是路线：

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")
}

当我在本地主机上运行它时，代码工作得很好，但是当我使用Heroku部署它时，我会得到一个500错误。

有什么文件我不应该推给heroku吗？我想指出，在server.json中，主机值是0.0.0.0。

这是我的Heroku日志(请注意，我多次重新部署它。所有这些都不起作用)：

Answer 1

Slack通道的一个用户给了我对这个问题的洞察力。

VZSG：@animatronicgopher:在Heroku上做实验很便宜，但是仅仅因为这一点就把它扩展到付费dynos是毫无意义的。这没有什么区别--首先，这个错误是由HTTP客户端生成的，所以服务器的证书无关紧要，其次，即使是免费的dynos也有正确的证书(而且它们也不仅仅是letsencrypt )。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->错误。

另外，GitHub中有一个问题，它给出了如何使用FoundationClient的示例。https://github.com/vapor/vapor/issues/699

Answer 2

如何使用Vapor框架创建快速后端API。市场上也有另一个框架。但我们选择的是快速蒸汽。

我们开始吧。

在你的系统中安装蒸汽。

步骤1.运行下面的命令来安装蒸气

brew安装蒸汽/tap/蒸气-β

检查蒸汽安装是否在命令下运行。

蒸汽-β-帮助

这将是有用的蒸汽控制。

只有在项目目录中时才会发出命令。你可以的

创造蒸汽项目

蒸汽新myProjectName

造汽工程

蒸汽建造

运行蒸汽项目

蒸汽运行

您可以配置Xcode。您应该在创建的项目目录中。

蒸汽X码

在对项目文件进行更改或为更新添加新功能时，您可以使用下面的命令。

蒸汽X码

您可以通过本地服务器测试API运行。外面将是“你好世界”

卷曲http://localhost:8080/hello

===========================================PostgreSQL Setup================================================

设置本地PrortgeSQL。按照命令运行。

Brew安装postgresql

启动本地数据库服务器。在命令下面运行

pg_ctl -D /usr/local/var/postgres启动

停止本地数据库服务器。按照命令运行。

pg_ctl -D /usr/local/var/postgres停止

当yow希望将PostgreSQL作为后台服务运行时，可以使用brew服务器。按照命令运行。

brew服务启动postgresql

让Postgres从这个开始。

psql -d postgres

通过运行以下命令创建数据库：

创建数据库databaseName

实际命令创建数据库

通过在命令下面运行创建用户：-通过在命令下面运行授予该用户所需的特权。

创建用户用户名

实际命令创建用户ashi-app-user

将数据库databaseName上的所有权限授予userName

实际命令将数据库ashi-app上的所有权限授予ashi-app-user ===========================================PostgreSQL Setup================================================。

===========================================Deploy在Heroku================================================上的新应用

在没有数据库的Heroku上部署新的快速蒸汽应用程序。

假设您已经创建了一个没有数据库的Vapor项目。

步骤1.在cd MyApp上导航。

cd myApp实际命令cd ashi-api

步骤2.在根目录中创建一个快速版本文件。在终点站下面跑。

5.1.3=‘5.1.3 5’>.5.1.3=‘5.1.3 1’>快速版

步骤3.在终端上的根项目directory.Run中创建Procfile文件。

echo‘web:运行serve -env生产--端口$PORT --主机名0.0.0.0’> Procfile文件

步骤4.通过下面的命令git添加文件git并提交。

git提交-m‘应用程序安装’

步骤5.您应该通过下面的命令生成linux测试文件。

快速测试-生成-linuxmain

步骤6.在git中添加下面的命令。

吉特加。

git提交-m‘测试设置’

步骤7.登录Heroku。需要在heroku上创建用于部署的应用程序。所以我们要登录heruko。通过运行下面的命令，我们可以登录。

heroku登录

步骤8.一旦登录完成，创建heroku应用程序。名称必须唯一，最喜欢的是应用程序名称。

heroku应用程序:创建myAppName

实际命令heroku应用程序:创建ashi-api

步骤9 :使用app添加快速构建包。为了在此编译，我们必须添加内置。Heroku不支持快速内置包。

heroku构建包:set https://github.com/vapor-community/heroku-buildpack -a myproject

实际命令heroku buildpack:设置https://github.com/vapor-community/heroku-buildpack -a ashi-api

步骤10.在服务器上查找命令推送更改。

git推heroku大师

现在您的应用程序和API将用于测试…。

===========================================Deploy在Heroku================================================上的新应用

======================Set数据库与部署的app和下一个版本的deployment==================================

步骤1.进行数据库配置。用postgreSQL代替sqlite数据库。因为Heroku不支持sqlite。

在App->配置中替换。并在Todo.h中导入TodoController.h

导入FluentPostgreSQL

//配置PostgreSQL数据库让postgreSQLConfig: PostgreSQLDatabaseConfig

if let url = Environment.get("DATABASE_URL") {
  postgreSQLConfig = PostgreSQLDatabaseConfig(url: url)!
} else {
  postgreSQLConfig = PostgreSQLDatabaseConfig(hostname: "localhost", username: "app_test")
}
let postgreSQL = PostgreSQLDatabase(config: postgreSQLConfig)

// Register the configured PostreSQL database to the database config.
var databases = DatabasesConfig()
databases.add(database: postgreSQL, as: .psql)
services.register(databases)

步骤2.通过运行安装带有家庭酿造的heroku命令。

brew龙头英雄/ brew && brew安装heroku

第三步，我们可以通过运行命令在app中添加postgreSQL。

英雄加载项:创建英雄-postgresql:业余爱好-dev

步骤4.通过运行下面的命令在git中添加update文件。

吉特加。

git提交-m‘添加了PostgreSQL文件’

步骤5.在服务器上查找命令推送更改。

git推heroku大师

第二个版本将用于使用postgreSQL进行测试。

======================Set数据库与部署的app和下一个版本的deployment==================================

======================测试应用程序API ==================================

步骤1. Heroku路径将是。你的https://app-name.herokoapp.com/youapIURL。

Heroku部署的应用程序名

样本获取

apiURL

数据获取请求

apiURL

邮递员的邮件请求。

apiURL

跟着链接。

在终端机上执行命令。

卷曲apiURL

在终端上运行post命令。

curl -x POST -H“ContentType”：application/json -d‘{“title:exaple”}’apiURL

======================测试应用程序API ==================================

======================其他重要的git和英雄日志命令==================================

1. 向heroku添加本地存储库。

git远程添加heroku appPath

1. 请参阅远程推送和获取存储库路径。

git远程-v

1. 见heroku应用程序

heroku应用程序

1. 参见heroku应用程序日志

线路数

heroku日志-n 100
