Web API 2中的多个参数

本文介绍了Web API 2中的多个参数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我想制作一个通过4个参数传递的网络api.

I want to make a web api that is passed 4 parameters.

这是我的路线:

config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{email}/{firstname}/{lastname}/{source}" );

这是方法签名

public string GetId(string email, string firstname, string lastname, string source)

这是主叫网址

fakedomain/api/Contacts/GetId?email=user@domain&firstname=joe&lastname=shmoe&source=123

我收到404错误.

如果我在路由配置中将每个参数设置为可选，并使用默认值设置每个参数，则会调用该参数.但是，每个参数都将使用默认值，而不是传递的值.

If I set each parameter to optional in the route config, and set up each argument with a default value it gets called. However, each argument gets the default value and not the passed value.

我感觉自己很亲密，我想念什么?

I feel like I am close, what am I missing?

推荐答案

确保WebApiConfig.cs文件中具有默认的api路由设置.

Ensure you have default api route setting in WebApiConfig.cs file.

public static class WebApiConfig { public static void Register(HttpConfiguration config) { // Web API configuration and services // Web API routes config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{id}", defaults: new { id = RouteParameter.Optional } ); config.Routes.MapHttpRoute( name: "ContactApi", routeTemplate: "api/{controller}/{email}/{firstname}/{lastname}/{source}" ); } } fakedomain/api/Contacts/GetId?email=user@domain&firstname=joe&lastname=shmoe&source=123

注意:我用localhost替换了法域，它可以工作...(localhost/api/Contacts/GetId?email=user@domain& first = joe& lastname = shmoe& source = 123)

Note : I replaced fakedomain with localhost and it works... (localhost/api/Contacts/GetId?email=user@domain&firstname=joe&lastname=shmoe&source=123)
