javascript - 跨域出错问题

Question

使用reqwest.js进行跨域，报这个错误：

reqwest.min.js:6 Refused to connect to 'http://115.29.102.81:8090/get...' because it violates the following Content Security Policy directive: "default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'". Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback.

代码：

reqwest({
                url:'http://115.29.102.81:8090/getsomearticle/' + that.number, 
                crossOrigin: true,
                success:function (data) {
                ......
                }
                });
           

原生xhr2的话没错，服务端设置也没错，请问这是为什么
