web api get正在工作，但发布和删除在iis中发布后不工作

我已经挣扎了4个小时，仍然没有找到任何解决办法。我已经应用了一些修改，但我的post和delete api仍然返回错误500

获取js

$.getJSON(API_URL + 'api/claim/search', params).done(function (data) {
    myJsonObject = data;
    d.resolve(data);
});
return d.promise();

原料药

这是我的WebApi.Config.cs

public static void Register(HttpConfiguration config)
{
    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );

}

我已经在我的配置中应用了这个Web服务器

我有一个类似的问题，它与捕获请求的函数名有关。出于某种原因，GET函数会自动执行此操作，但POST并不总是这样做。您可以尝试这样显式命名它，看看它是否也解决了您的问题：

[Route("api/claim/savepatient")]
[System.Web.Http.AcceptVerbs("POST")]
[System.Web.Http.HttpPost, ActionName("SavePatient")]
public Guid SavePatient([FromBody]ClaimInfo claimInfo)
{
    //my code
}

请注意，我将

[System.Web.Http.HttpPost]

更改为

[System.Web.Http.HttpPost，ActionName（“SavePatient”）]

您将操作命名为“SavePatient”，而不是Post。路由器将/api/{controller}与{controller}控制器类匹配。HTTP方法必须与类的公共方法匹配。尝试将“SavePatient”重命名为“Post”（如果使用该方法，则为“Put”）

并删除url上的额外路径：

url: API_URL + "api/claim/"

如果在可疑动作中放置断点，是否命中？错误是在执行操作之前还是之后发生的？您找到解决方案了吗？
