1.传统的ajax请求时候,
Content-Type
默认为"文本"类型。2.传统的form提交的时候,
Content-Type
默认为"Form"类型。
function submit3() {
var p1 = 'name=a&val=b';
var p1 = {name: a, val: b};
axios.post('/url', p1 )
}
当传递的是字符串的时候:application/x-www-form-urlencoded
当传递的是对象的时候:application/json
总结:
1.axios传递字符串的时候,
Content-Type
默认为"Form"类型。2.axios传递对象的时候,
Content-Type
默认为"JSON"类型
