Question

我已使用form submit创建了html页面。在提交时，我正在调用ajax post请求。但抛出错误

无法加载http://radius.a3techlabs.com/app/custom/verifyAccessOTP：对预检请求的响应未通过访问控制检查：“访问控制 - 允许 - 来源”＆＃39;标头包含无效值＆＃39;＆＃39;。起源＆＃39; null＆＃39;因此不允许访问。

$.ajax({
      url: 'http://radius.a3techlabs.com/app/custom/verifyAccessOTP',
      dataType: 'json',
      type:'post',
      headers: {
          "charset":"UTF-8",
          "accept": "application/json",
          "Access-Control-Allow-Origin":"*",
          "Access-Control-Allow-Credentials":"true",
        },
      data:value,
      success: function(data) {
        console.log(data);   
        alert(data.message);
      }.bind(this),
      error: function(xhr, status, err) {}.bind(this)
    });

Answer 1

module.exports.cors = {
  allRoutes: false,
  origin: '*',
  credentials: true,
  methods: 'GET, POST, PUT, DELETE, OPTIONS, HEAD',
  headers: 'content-type'
};

改变

allRoutes：真

module.exports.cors = {
  allRoutes: true,
  origin: '*',
  credentials: true,
  methods: 'GET, POST, PUT, DELETE, OPTIONS, HEAD',
  headers: 'content-type'
};

它有效，

Access-Control-Allow-Origin标头包含无效值
