Question

我一直想知道为什么我的客户总是需要为我的网站清除浏览器缓存。原来，角度文件无法正确构建。或者更确切地说，它们得到了构建，但是它们的名称没有被散列，因此其名称与以前的版本相同，因此浏览器认为没有任何变化。

下面是我的.csproj：

    <Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.2</TargetFramework>
    <TypeScriptCompileBlocked>true</TypeScriptCompileBlocked>
    <TypeScriptToolsVersion>Latest</TypeScriptToolsVersion>
    <IsPackable>false</IsPackable>
    <SpaRoot>ClientApp\</SpaRoot>
    <DefaultItemExcludes>$(DefaultItemExcludes);$(SpaRoot)node_modules\**</DefaultItemExcludes>

    <!-- Set this to true if you enable server-side prerendering -->
    <BuildServerSideRenderer>false</BuildServerSideRenderer>
    <UserSecretsId>c69ca95c-16a6-4f76-bb29-b4d09b2a4417</UserSecretsId>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="CsvHelper" Version="12.1.1" />
    <PackageReference Include="EPPlus" Version="4.5.3.1" />
    <PackageReference Include="Microsoft.AspNetCore.App" />
    <PackageReference Include="Microsoft.AspNetCore.Razor.Design" Version="2.2.0" PrivateAssets="All" />
    <PackageReference Include="Sendgrid" Version="9.10.0" />
    <PackageReference Include="WindowsAzure.Storage" Version="9.3.3" />
  </ItemGroup>

  <ItemGroup>
    <!-- Don't publish the SPA source files, but do show them in the project files list -->
    <Content Remove="$(SpaRoot)**" />
    <None Remove="$(SpaRoot)**" />
    <None Include="$(SpaRoot)**" Exclude="$(SpaRoot)node_modules\**" />
  </ItemGroup>


  <Target Name="DebugEnsureNodeEnv" BeforeTargets="Build" Condition=" '$(Configuration)' == 'Debug' And !Exists('$(SpaRoot)node_modules') ">
    <!-- Ensure Node.js is installed -->
    <Exec Command="node --version" ContinueOnError="true">
      <Output TaskParameter="ExitCode" PropertyName="ErrorCode" />
    </Exec>
    <Error Condition="'$(ErrorCode)' != '0'" Text="Node.js is required to build and run this project. To continue, please install Node.js from https://nodejs.org/, and then restart your command prompt or IDE." />
    <Message Importance="high" Text="Restoring dependencies using 'npm'. This may take several minutes..." />
    <Exec WorkingDirectory="$(SpaRoot)" Command="npm install" />
  </Target>

  <Target Name="PublishRunWebpack" AfterTargets="ComputeFilesToPublish">
    <!-- As part of publishing, ensure the JS resources are freshly built in production mode -->
    <Exec WorkingDirectory="$(SpaRoot)" Command="npm install" />
    <Exec WorkingDirectory="$(SpaRoot)" Command="npm run build --prod" />
    <Exec WorkingDirectory="$(SpaRoot)" Command="npm run build:ssr --prod" Condition=" '$(BuildServerSideRenderer)' == 'true' " />

    <!-- Include the newly-built files in the publish output -->
    <ItemGroup>
      <DistFiles Include="$(SpaRoot)dist\**; $(SpaRoot)dist-server\**" />
      <DistFiles Include="$(SpaRoot)node_modules\**" Condition="'$(BuildServerSideRenderer)' == 'true'" />
      <ResolvedFileToPublish Include="@(DistFiles->'%(FullPath)')" Exclude="@(ResolvedFileToPublish)">
        <RelativePath>%(DistFiles.Identity)</RelativePath>
        <CopyToPublishDirectory>PreserveNewest</CopyToPublishDirectory>
      </ResolvedFileToPublish>
    </ItemGroup>
  </Target>

</Project>

结果是，由于angular不在生产模式下，因此无法运行“ npm run build --prod”。我如何做到这一点，以便我的产品在Visual Studio中的生产发布设置以生产模式构建角度，而我的开发服务器获得开发构建？

Answer 1

将命令更改为npm run build -- --prod。
这会将prod参数传递给下面的ng build命令，因此将执行正确的命令（ng build --prod）。

Answer 2

如果您查看package.json文件内部，则build命令将运行ng build。即使您指定了--prod，这些选项也不会转换为package.json中的命令。这是几个选项。

在您的package.json文件中，您可以创建另一个生产命令。

"scripts": {
  ...
  "build": "ng build",
  "build-prod": "ng build --prod"
  ...  
},

然后您可以运行npm run build-prod。或作为第二种选择，您只需运行angular-cli命令ng build --prod

Answer 3

我必须结合使用Jason White的答案和SNIPEZ，才能使我的工作正常进行。

添加

try {
    result = await myApiCall(options);
} catch (reason) {
    // ...
}

// At this point, the call succeeded, but I would like to not only investigate the
// properties from `SomeModel`, but also, from the normal `request` response
if (result.response.statusCode) {
    // ...
}

进入package.json，并将.csproj文件更改为

"build-prod": "ng build --prod"

为我工作

Answer 4

执行命令 ng build --prod

如何在生产模式下发布角度文件？
