一、概述
既然前后端开发完全分离,那么接口的测试和文档就显得非常重要,文档维护是一件比较麻烦的事情,特别是变更的文档,这时采用Swagger就会非常方便,同时解决了测试和接口文档两个问题。
二、使用NuGet获取包
使用NuGet搜索包:Swashbuckle.aspnetcore并安装。
三、添加代码
在Startup类的ConfigureServices方法内添加下面代码(加粗部分)
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc(); services.AddSwaggerGen(option =>
{
option.SwaggerDoc("v1", new Info
{
Version = "v1",
Title = "SaleService接口文档",
Description = "RESTful API for SaleService.",
TermsOfService = "None",
Contact = new Contact { Name = "seabluescn", Email = "seabluescn@163.com", Url = "" }
}); //Set the comments path for the swagger json and ui.
var basePath = PlatformServices.Default.Application.ApplicationBasePath;
var xmlPath = Path.Combine(basePath, "SaleService.xml");
option.IncludeXmlComments(xmlPath);
});
}
在Startup类的Configure方法内添加下面代码(加粗部分)
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
app.UseMvcWithDefaultRoute(); app.UseSwagger();
app.UseSwaggerUI(option =>
{
option.ShowExtensions();
option.SwaggerEndpoint("/swagger/v1/swagger.json", "SaleService V1");
});
}
四、配置
需要在生成配置选项内勾选XML文档文件,项目编译时会生成该文件。Debug和Release模式都设置一下。否则会报一个System.IO.FileNotFoundException的错误。
五、启动
启动项目,浏览器输入:http://localhost:50793/swagger/ 即可。
也可以修改launchsettings.json文件,默认项目启动时运行swagger
{
"iisSettings": {
"windowsAuthentication": false,
"anonymousAuthentication": true,
"iisExpress": {
"applicationUrl": "http://localhost:50792/",
"sslPort": 0
}
},
"profiles": {
"IIS Express": {
"commandName": "IISExpress",
"launchBrowser": true,
"launchUrl": "api/values",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
}
},
"SaleService": {
"commandName": "Project",
"launchBrowser": true,
"launchUrl": "swagger",
"environmentVariables": {
"ASPNETCORE_ENVIRONMENT": "Development"
},
"applicationUrl": "http://localhost:50793/"
}
}}
如果你对你的控制器方法进行了注释,swagger接口页面就会体现出来。
/// <summary>
/// 根据产品编号查询产品信息
/// </summary>
/// <param name="code">产品编码</param>
/// <returns>产品信息</returns>
[HttpGet("{code}")]
public Product GetProduct(String code)
{
var product = new Product
{
ProductCode = code,
ProductName = "啫喱水"
}; return product;
}
下面为Swagger的首页:可以用它进行API的调试了。
