前言

在很多业务场景中经常会遇到调用web api接口，并且把参数传递给web api，下面将一起了解一下如何在.net core中调用web api，并且将json字符串传递给post方法

环境和组件

环境：.net core

组件：RestSharp（可以通过NuGget组件包添加到项目组）

具体实现

1、web api方法

//注意：.net core web api支持dynamic，实例中是将请求过来的json字符串转换为了list
[HttpPost("SyncNews")]
        public async void SyncNews([FromBody] List<Article> data)
        {
            
            try
            {
                //此处是调用entity framework把数据插入到数据库
                var articleRepository = new ArticleRepository();
                await articleRepository.SyncDataAsync(data);
               
                
            }
            catch (Exception ex)
            {
                
                //此处写log日志等
            }
            
        }


//业务方法
public async Task SyncDataAsync(List<Article> articles)
        {
            using (var db = new PortalManagementContext())
            {

                foreach (var item in articles)
                {
                    db.Articles.Add(item);
                }

                await db.SaveChangesAsync();
            }
        }

 2、调用web api(Post)

下面是调用web api的两种方式

.net core请求:

//articles为Article集合
 List<Article> newaddArticleList = articles;
            var ArticleServiceUrl = RandUXML.Read("ArticleServiceUrl");
            var clientsharp = new RestClient(ArticleServiceUrl+"api/Article/SyncNews");
            clientsharp.Timeout = -1;
            var request = new RestRequest(Method.POST);
            request.AddHeader("Content-Type", "application/json");
            //将list集合转换为json字符串，并传递给web api
            string ListJson = JsonConvert.SerializeObject(articles);
            request.AddParameter("application/json", ListJson, ParameterType.RequestBody);
            IRestResponse response = clientsharp.Execute(request);
            Console.WriteLine(response.Content);


Ajax请求：

var settings = {
  "url": weburl+"/api/Article/SyncNews",
  "method": "POST",
  "timeout": 0,
  "headers": {
    "Content-Type": "application/json"
  },
  "data": JSON.stringify("json字符串"),
};

$.ajax(settings).done(function (response) {
  console.log(response);
});

3、调用web api(Get)

下面是.net core及JQuery调用web api方法

.Net Core:
var client = new RestClient(weburl+"/api/Article/GetAllArticles");
client.Timeout = -1;
var request = new RestRequest(Method.GET);
IRestResponse response = client.Execute(request);
Console.WriteLine(response.Content);

JQuery：
var settings = {
  "url": weburl+"/api/Article/GetAllArticles",
  "method": "GET",
  "timeout": 0,
};

$.ajax(settings).done(function (response) {
  console.log(response);
});

如上就是.net core调用web api的方法，如上描述如有错漏请大家评论区直接留言，多谢
