vue2.x的axios跨域访问资源问题

代码如下

 this.$axios({
      headers: {
        "Content-Type": "application/x-www-form-urlencoded;charset=UTF-8"
      },
      method: "POST",
      url: "http://crm.tonyliangli.cn/api/company/companyUsers",
      data: {
        token: "1511328705UZVQ"
      }
    })
      .then(function(res) {
        console.log(res);
      })
      .catch(function(err) {
        console.log(err);
      });

加上headers之后传递不过去参数
不加报错: Failed to load http://crm.tonyliangli.cn/api/company/companyUsers: Request header field Content-Type is not allowed by Access-Control-Allow-Headers in preflight response.

这是什么原因啊 来大神解答下
