.NET 处理WEBAPI跨域问题 1.跨域问题导致的原因出于安全考虑，浏览器会限制脚本中发起的跨站请求，浏览器要求JavaScript或Cookie只能访问同域下的内容。由于这个原因，我们不同站点之间的数据访问会被拒绝。 2.解决方案 2.1.导入microsoft.aspnet.webapi.cors.dll 点击项目下面的引入，选择“管理NuGet程序包” 搜索microsoft.aspnet.webapi.cors 点击“安装”即可。 2.2.代码实现在App_Start文件夹下面的WebApiConf 阅读详情

我根据网上的做法在NuGet上下载Cors引用，用 [EnableCors(origins: "http://myclient.azurewebsites.net", headers: "*", methods: "*")]这种方式来实现跨域问题，但是为什么每次下载下来的引用后，生成成功，运行就报

请叫我鱼拆，2024扫地机器人的第一次拆机从背面可以看出，这个机器人是两轮差速模型，两个驱动轮，一个万向轮，驱动轮位于机器人中心位置，这样原地旋转的圆心就是机器人的中心。可以看到设备已经连接，但是没有办法进shell，厂家应该有做了安全保护之类的，有知道从这个口可以登录系统办法的小伙伴可以后台留言。但这台机器人一直报警说，机器人轮子离地，小鱼估计是防跌落模块有问题，误触发了，所以打算先拆机看看。接着小鱼试了下，机器可以开机，然后给他重新配置wifi，连上米家。Allwinner，全志的片子，不知道哪个型号的，看产品id，应该支持adb。阅读详情

这个问题我解决了. 正如楼上所说, 是5,2,2和5,2,3依赖的问题. 先把所有5.2.2的dll去掉, 改成5.2.3的. 在Web.config中, 强制指定5.2.3 <dependentAssembly> <assemblyIdentity name="System.Web.Http" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-5.2.3.0" newVersion="5.2.3.0" /> </dependentAssembly> <dependentAssembly> <assemblyIdentity name="System.Net.Http.Formatting" publicKeyToken="31bf3856ad364e35" /> <bindingRedirect oldVersion="1.0.0.0-5.2.3.0" newVersion="5.2.3.0" /> </dependentAssembly>

测试代码

[EnableCors(origins: "http://localhost:3476,http://localhost:2426", headers: "*", methods: "*")]
        // POST api/values
        public string Post([FromBody]string value)
        {
            return string.Format("T takes a message:{0}", value ?? string.Empty);
        }

测试js

$().ready(function () {
            $.ajax('http://localhost:7333/api/Values', {
                data: { value: "test" },
                type: 'post',
                success: function (data) {
                    alert(data);
                },
                error: function () {
                }
            });
        });
