在php（服务端）返回上传成功后的路径给浏览器（客服端）
做图片预览的话，服务器端上传成功之后返回前端一个图片的地址，前端再将图片显示出来
这样可以在浏览器生成图片的地址提前预览 不需要等到服务器返回地址
function getObjectURL(file) {
var url = null;
if (window.createObjectURL != undefined) { // ie
url = window.createObjectURL(file);
} else if (window.URL != undefined) { // 火狐
url = window.URL.createObjectURL(file);
} else if (window.webkitURL != undefined) { // 谷歌
url = window.webkitURL.createObjectURL(file);
}
return url;
}
图片上传成功后，需要后端返回成功信息。
具体要和后端商量。
立即学习“Java免费学习笔记（深入）”；
看API接口文档，返回什么参数。需要用到什么，就和后端沟通。
将图片路径存到数据库里面，再读取出来
一般都是后端把路径返回前端，你们后端要闹哪样
一般都是后端生成生给你一个URL的，你问下response回来是什么打出来看看，或者直接问后端的开发人员
通过上传接口上传图片，通常接口会返回相关数据，比如:
{data:{status:1,imgPath:"/xxx/xx.png"}}
status 上传的状态（上传成功，上传不成功），imgPath上传成功通常会给出访问图片的地址。
通过返回的图片地址就可访问图片了
