前台代码：(category是数组)

var data = {
			title: title,
			category: category.split(","),
			cancomment: cancomment,
			content: content,
			totalWords: totalWords
		};

		$.ajax({
			type: "POST",
			url: "/addArticle",
			traditional :true,
			// contentType: "application/json",
			// data: JSON.stringify(data),
			data: data,
			success: function(msg) {
				var msgObject = JSON.parse(msg);
				if(msgObject.Status === true) {
					// window.location.href = msgObject.Url;
				}
			}
		});
