vue 封装get 和post请求

get 和post请求的参数传法不一样，要注意

		Vue.prototype.post = function (url, param, callback) {
     
			return new Promise((resolve, reject) => {
     
				var sessionid = localStorage.getItem('sessionid');
				Vue.http.post(url, param, {
      headers: {
      Authorization: sessionid }, emulateJSON: true }).then((res) => {
     
					if (res.body.success) {
     
						resolve(res.body);
					}
					if (res.body.code == '403') {
     
						localStorage.clear();
						this.$cookiesStore.delCookie('access_token');
						this.$router.push('/');
						if (typeof (callback) == 'function') {
     
							callback(res)
						}
						return;
					}
					if (res.body.code != '200') {
     
						this.$loading(false);
						this.$toast(res.body.msg, 2000, 'error');
					}
					if (typeof (callback) == 'function') {
     
						callback(res)
					}
				}).catch((res) => {
     
					reject(res.body);
				});
			});
		};

		Vue.prototype.get = function (url, param) {
     
			return new Promise((resolve, reject) => {
     
				var sessionid = localStorage.getItem('sessionid');
				// url = param ? `${url}?${qsStringify(param)}` : url;
				Vue.http.get(url, {
     
					params: param,
					headers: {
     
						Authorization: sessionid,
						// Accept: 'application/json',
						// 'Content-Type': 'application/octet-stream;charset=UTF-8',
					},
				}).then((res) => {
     
					if (res.status == '200') {
     
						resolve(res.body);
					}

				}).catch((res) => {
     
					reject(res.body);
				});
			});
		};
