页面部分大概意思一下
<form method="post" enctype="multipart/form-data">
...
</form>
axios部分代码以vue示例：
//提交表单
onSubmit(e) {
e = e || event;
e.preventDefault();
let self = this;
let formData = new FormData();
formData.append("idCard", self.cardImageFile);//文件
formData.append("idType", "1");
formData.append("idNumber", self.cardNo); let config = {
headers: {
"Content-Type": "multipart/form-data"
}
};
self.$http.post("/upload", formData, config).then(
function(response) {
if (response.data.code == 200 && response.data.success) {
/*这里做处理*/
}
},
response => {}
);
},
文件在onchange事件里面取file
无刷新提交表单到此就结束了
