vue中this.$http.post()跨域和请求参数丢失的解决

methods: {
    research: function () {
        //post请求远程资源
        this.$http.post(
            //请求的url
            "http://www.hefeixyh.com/login.html",
            //请求参数，不能以get请求方式写：{params: {userName: "root123", passWord: "root123"}}
            {userName: "root123", passWord: "root123"},
            //解决跨域问题，不加无法跨域
            {emulateJSON: true}
        ).then(
            function (res) {
                console.log(res);
                this.msg = res.bodyText;
            },
            function (res) {
                console.log(res.status);
            }
        );
    }
}

this.http.post('url' + id, {})

.subscribe(res => {
}, error => {
})
