Azure App 服务无法启动，因为它无法使用 ASP.NET Core 找到 swagger 文档 xml [英] Azure App service can't start because it can't find swagger documentation xml using ASP.NET Core
问题描述
更新 2: 文件未发布.那是错误的.但是，我不明白为什么我的一台计算机可以以正确的方式发布它而另一台在 Visual Studio 升级后却不能.
Update 2: The file does not get published. That is what is wrong. However, I can't figure out why one of my computers can publish it the right way and the other doesn't after the Visual studio upgrade.
更新:在两台不同的计算机上运行相同的解决方案，其中 APIProject.xml 文件从一台计算机正确发布，而另一台则没有，现在只剩下一个差异.用于发布的计算机运行 Visual Studio 2017 Enterprise 的未更新版本.15.5.2 不起作用而 15.4.2 起作用.
Update: Running the same solution on two different computers where the APIProject.xml file get's correctly published from one computer but not the other there are now only one difference left. The computer from which the publishing works runs the not updated version of Visual studio 2017 Enterprise. 15.5.2 does not work and 15.4.2 works.
我收到此错误:
FileNotFoundException: 找不到文件'D:homesitewwwrootAPIProject.xml'.
FileNotFoundException: Could not find file 'D:homesitewwwrootAPIProject.xml'.
文件放在binDebug etcoreapp2.0它在本地工作，但发布到 Azure 应用服务时会崩溃.
The file is placed in binDebug etcoreapp2.0 It works locally but when published to Azure App service it crashes.
我正在发布到我创建的暂存槽，但尚未尝试生产.发布会替换目的地的所有文件.
I'm publishing to the staging slot I created and haven't tried production yet. Publishing replaces all files at destination.
这是我对 Swagger 的设置，但它曾经可以工作:)
Here is my setup of Swagger but it used to work :)
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc();
// Register the Swagger generator, defining one or more Swagger documents
services.AddSwaggerGen(c =>
{
c.SwaggerDoc("v1", new Info
{
Version = "v1",
Title = "Ecommerce/Product API",
Description = "Handles API based shopping functionality",
TermsOfService = "Terms of service should be contracted with inidividually",
Contact = new Contact { Name = "Magnus", Email = "magnus@secret", Url = "" },
License = new License { Name = "Use under permission from our Group", Url = "http://aboutno" }
});
// Set the comments path for the Swagger JSON and UI.
var basePath = PlatformServices.Default.Application.ApplicationBasePath;
var xmlPath = Path.Combine(basePath, "APIProject.xml");
c.IncludeXmlComments(xmlPath);
});
}
发生变化的是我在 Program.cs 中添加了UseSetting"行，以获取有关为什么它不启动的错误信息.在添加该行之前，我没有收到开发人员错误，只有最终用户错误页面.
What has changed is I added the "UseSetting"-row in Program.cs to get errors of why it doesn't start. Before adding that row I did't get developer error, only got end user error page.
public static IWebHost BuildWebHost(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseApplicationInsights()
.UseSetting(WebHostDefaults.DetailedErrorsKey, "true")
.UseStartup<Startup>()
.Build();
我正在尝试以调试模式发布.还尝试使用 Release 作为下面的一个答案，但没有区别.
I'm trying to publish with Debug mode. Also tried with Release as of one answer below but no difference.
我在另一台计算机上检查了代码并且从那台计算机上发布了代码，所以这个问题对我来说变得更奇怪了！
I checked out the code in another computer and publishing from that computer works so the problem just got more weird to me!
推荐答案
我的 .Net Core 2.0 应用程序在本地运行良好，但抛出了一个毫无意义的启动应用程序时出错." 部署到 Azure 时出现错误.
My .Net Core 2.0 app worked fine locally, but threw a pointless "An error occurred while starting the application." error when deployed to Azure.
检查日志，原因是 Swagger 找不到特定的 .xml 文件(为什么错误消息不让我们知道?！)
Checking the logs, the cause was that Swagger couldn't find a particular .xml file (why the hell doesn't the error message let us know ?!)
解决方案是选择构建选项卡，将配置下拉列表更改为发布"，然后勾选此框:
The solution was to select the Build tab, change the Configuration drop down list to "Release", then tick this box:
就是这样.
出于某种原因，默认情况下它被勾选(填写了 .xml 文件名)用于调试，而不是用于发布.
For some reason, by default it was ticked (with the .xml filename filled in) for Debug, but not for Release.
(叹气.)
