AJAX Post 测试方法加载资源失败

Question

我创建了一个调用我的 MVC 应用程序的测试 Web 应用程序。我可以使用 Postman 正常调用 POST 并想尝试从 Web 浏览器调用它，但出现 405 错误。任何帮助都会很棒。

Failed to load resource: the server responded with a status of 405 (Method Not Allowed)

测试HTML项目

$.ajax({  
type: "POST",  
url: "URL",  
headers: {
'Access-Control-Allow-Origin': '*',
'Content-Type': 'application/json'
},
contentType: "application/json; charset=utf-8",  
dataType: "jsonp", 
crossDomain: true,
success: function (response) {  
   console.log('message: ' + "success" + JSON.stringify(json));   
                 },  
failure: function (error) {  
   console.log('message Error' + JSON.stringify(error));
   }  
});

MVC 应用程序

public class PublicController : ApiController
    {
        [System.Web.Http.HttpPost]
        public IHttpActionResult MethodTest(string key, string action)
        {
        }
     }

web.config

<httpProtocol>
      <customHeaders>
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Headers" value="Content-Type" />
        <add name="Access-Control-Allow-Methods" value="GET,POST,PUT,DELETE,OPTIONS" />
      </customHeaders>
    </httpProtocol>

您必须修复 ajax.remove headers 和内容类型并修复数据类型并添加数据

$.ajax({  
type: "POST",  
url: "http://localhost:60876/WebApi/public/SkipAuthenticationAndLogin"  
data:{
key:"key",
userName:"name",
succesUrl:"url"
},
dataType: "json", 
success: function (response) {  
   console.log('message: ' + "success" + JSON.stringify(response));   
                 },  
failure: function (error) {  
   console.log('message Error' + JSON.stringify(error));
   }  
});

并从操作中删除 post


 public IHttpActionResult MethodTest(string key, string userName, string successUrl)
 {
}
