一、axios的post请求 方式

1.方式1拼接

 send: function () { 
	 axios.post('post.php','name=alice&num=20&').then(resp=>{	
	  console.log(resp);	 
      this.josarr=resp.data.jokes	//数据赋值   
      
     }).catch(resp =>{
      console.log('failure');
     })
    }

2.对于参数复杂的 先定义参数数组 传值用transformRequest函数循环凭借

js代码

new Vue({
				el:'#itany',
				data:{
					user:{
						 name:'alice',
						 age:19
					}
				},
				methods:{					
					sendPost(){
						axios.post('server.php',this.user,{
							transformRequest:[
								function(data){
									let params='';
									for(let index in data){
										params+=index+'='+data[index]+'&';
									}
									return params;
								}
							]
						})
						.then(resp => {
							console.log(resp.data);
						}).catch(err => {
							console.log('请求失败：'+err.status+','+err.statusText);
						});
					},
				
			
				}
			});

直接$http.post需要引用vue-resource.min.js

<script src="https://cdn.staticfile.org/vue-resource/1.5.1/vue-resource.min.js"></script>

jsonp跨域 模拟360搜索

sendJSONP(){
	//https://sug.so.360.cn/suggest?callback=suggest_so&encodein=utf-8&encodeout=utf-8&format=json&fields=word&word=a
	this.$http.jsonp('https://sug.so.360.cn/suggest',{
		params:{
			word:'a'
		}
	}).then(resp => {
		console.log(resp.data.s);
	});
},
