浏览器发送POST请求、DELETE请求

1.浏览器发送POST请求
方法一：

var xml = new XMLHttpRequest();
var url = "http://127.0.0.1:8800/admin/user";
xml.open("POST", url, true);
xml.setRequestHeader("Content-type", "application/json");
xml.setRequestHeader("Authorization","xxx");
xml.send('{"model": {"name": "测试接口","remark": "<p>测试接口接口<br></p>"}}');

方法二：

var url = "http://localhost:8800/admin/user"; //请求路径
var params = {
    "model": {
    	"name": "测试接口",
    	"remark": "<p>测试接口接口<br></p>"
    }
}; //此为json格式的参数
var xhr = new XMLHttpRequest();
xhr.open("POST", url, true);
xhr.setRequestHeader("Content-Type", "application/json");
xhr.setRequestHeader("Authorization","xxx");
xhr.onload = function (e) {
	if (xhr.readyState === 4) {
		if (xhr.status === 200) {
			console.log(xhr.responseText);
		} else {
			console.error(xhr.statusText);
		}
	}
};
xhr.send(JSON.stringify(params));
xhr.onerror = function (e) {
	console.error(xhr.statusText);
};

2. 浏览器发送DELETE请求

var xml = new XMLHttpRequest();
var url = "http://127.0.0.1:8800/admin/user/111000";
xml.open("DELETE", url, true);
xml.setRequestHeader("Content-type", "application/json");
xml.setRequestHeader("Authorization","xxx");
xml.send();
