react请求gateway数据(JSON)

 使用jquery,试了几个版本都出现同源问题,还是自己懂底层好哇,一点问题没有,完美

var api = 'xxx';

var xmlhttp = new XMLHttpRequest();
xmlhttp.open("POST", api, true);
xmlhttp.setRequestHeader("Content-Type", "application/json");
xmlhttp.send(JSON.stringify({
  "data": {
    "xx": "xx"
  }
}));
xmlhttp.onreadystatechange = function() {
  if (this.readyState === 4 && this.status === 200) {
    const response = JSON.parse(this.responseText);
    console.log('index.html: 25 -> onreadystatechange -> ', response);
  }
};
