[asp.net core]project.json（1）

摘要

前面介绍了使用vs2015新建asp.net core web的内容，这篇文章学习下project.json文件的内容。

project.json

原文：https://docs.microsoft.com/zh-cn/dotnet/articles/core/tools/project-json

project.json文件用来定义asp.net core项目的元数据，编译信息和依赖。在本篇文章中，你可以看到你能在project.json中定义的所有属性列表。

dependencies

类型：Object

定义了项目依赖的包，包名称作为键名，值为版本信息。For more information, see the Dependency resolution article on the NuGet documentation site.

例子：

"dependencies": {
"System.Reflection.Metadata": "1.3.0",
"Microsoft.Extensions.JsonParser.Sources": {
"type": "build",
"version": "1.0.0-rc2-20221"
},
"Microsoft.Extensions.HashCodeCombiner.Sources": {
"type": "build",
"version": "1.1.0-alpha1-21456"
},
"Microsoft.Extensions.DependencyModel": "1.0.0-*"
}

version

Type: String

Specifies the version or version range of the dependency. Use the * wildcard to specify a floating dependency version.

For example:

"dependencies": {
"Newtonsoft.Json": {
"version": "9.0.1"
}
}

type

Type: String

Specifies the type of the dependency. It can be one of the following values:

default

,

build

or

platform

. The default value is

default

.

build

is known as a development dependency and is only used for build-time. It means that the package should not be published or added as a dependency to the output

.nupkg

file. It has the same effect of setting supressParent to

all

.

platform

references the shared SDK. For more information, see the section on "Deploying a framework-dependent deployment with third-party dependencies" on the .NET Core Application Deployment topic.

For example:

"dependencies": {
"Microsoft.NETCore.App": {
"type": "platform",
"version": "1.0.0"
}
}

target

Type: String

Restricts the dependency to match only a

project

or a

package

.

include

Type: String

all

,

runtime

,

compile

,

build

,

contentFiles

,

native

,

analyzers

, or

none

. Multiple flags are defined by a comma-delimited list. For more information, see the Managing dependency package assets specification on the NuGet repo.

For example:

{
"dependencies": {
"packageA": {
"version": "1.0.0",
"include": "runtime"
}
}
}

exclude

Type: String

Excludes parts of dependency packages. It can be one or more of the following flags:

all

,

runtime

,

compile

,

build

,

,

analyzers

, or

none

. Multiple flags are defined by a comma-delimited list. For more information, see the Managing dependency package assets specification on the NuGet repo.

For example:

{
"dependencies": {
"packageA": {
"version": "1.0.0",
"exclude": "contentFiles"
}
}
}

supressParent

Type: String

Defines additional excludes for consumers of the project. It can be one the following flags:

all

,

runtime

,

compile

,

build

,

contentFiles

,

native

,

analyzers

, or

none

. For more information, see the Managing dependency package assets specification on the NuGet repo.

{
"dependencies": {
"packageA": {
"version": "1.0.0",
"suppressParent": "compile"
}
}
}

tools

Type: Object

An object that defines package dependencies that are used as tools for the current project, not as references. Packages defined here are available in scripts that run during the build process, but they are not accessible to the code in the project itself. Tools can for example include code generators or post-build tools that perform tasks related to packing.

For example:

{
"tools": {
"MyObfuscator": "1.2.4"
}
}

scripts

Type: Object

An object that defines scripts run during the build process. Each key in this object identifies where in the build the script is run. Each value is either a string with the script to run or an array of strings containing scripts that will run in order. The supported events are:

precompile

postcompile

prepublish

postpublish

For example:

{
"scripts": {
"precompile": "generateCode.cmd",
"postcompile": [ "obfuscate.cmd", "removeTempFiles.cmd" ]
}
}

buildOptions

Type: Object

An object whose properties control various aspects of compilation. The valid properties are listed below. Can also be specified per target framework as described in the frameworks section.

For example:

"buildOptions": {
"allowUnsafe": true,
"emitEntryPoint": true
}

define

Type: String[]

A list of defines such as "DEBUG" or "TRACE" that can be used in conditional compilation in the code.

For example:

{
"buildOptions": {
"define": ["TEST", "OTHERCONDITION"]
}

nowarn

Type: String[]

A list of warnings to ignore.

For example:

{
"buildOptions": {
"nowarn": ["CS0168", "CS0219"]
}
}

This ignores the warnings

The variable 'var' is assigned but its value is never used

and

The variable 'var' is assigned but its value is never used

additionalArguments

A list of extra arguments that will be passed to the compiler.

For example:

{
"buildOptions": {
"additionalArguments": ["/parallel", "/nostdlib"]
}
}

{
"buildOptions": {
"warningsAsErrors": true
}
}

false

. The default is

false

.

For example:

{
"buildOptions": {
"allowUnsafe": true
}
}

emitEntryPoint

Type: Boolean

true

to create an executable;

false

to produce a library. The default is

false

.

For example:

{
"buildOptions": {
"emitEntryPoint": true
}
}

optimize

Type: Boolean

true

to enable the compiler to optimize the code in this project; otherwise,

false

. The default is

false

.

For example:

{
"buildOptions": {
"optimize": true

platform

Type: String

The name of the target platform, such as AnyCpu, x86 or x64.

For example:

For example:

{
"buildOptions": {
"languageVersion": "5"
}
}

keyFile

Type: String

The path for the key file used for signing this assembly.

For example:

{
"buildOptions": {
"keyFile": "../keyfile.snk"
}
}
