请求Data 转formData

某些特殊的请求 需要数据为表单格式

utils/formData.js
export const  toFormData  =  function (param){
	let data =  new FormData();
			for(let key in param){
				data.append(key, param[key]);
			}
			return data;
		}

export const  toForm  =function(param){

let formData =  new FormData();
	Object.keys(param).forEach(key => {
		formData.append(key, param[key]);
	});
		return formData
}

引入

// main.js
Vue.prototype.$toFormData = toForm;

使用

let Obj = { a:"123",b:"234" }
let param = this.$toFormData(Obj)

getTableInfo(param ).then(()=>{   
	// do something ...
})
