服务器返回数据格式
这是标准的返回数据格式。这里可以定制化，返回的json数据用来渲染template-down模板，参数名对应即可，也可以添加自己需要的参数
{
"files": [
{
"name": "PNG.png",
"size": 42971,
"type": "image/png",
"url": "http://localhost/UPLOAD/server/php/files/PNG.png",
"thumbnailUrl": "http://localhost/UPLOAD/server/php/files/thumbnail/PNG.png",
"deleteUrl": "http://localhost/UPLOAD/server/php/?file=PNG.png",
"deleteType": "DELETE"
}
]
}
Tips
跨域
确保访问地址正常
在服务器响应部分添加
header(“Access-Control-Allow-Origin: *”); # 跨域处理
header(“Access-Control-Allow-Methods:PUT,POST,GET,DELETE,OPTIONS”);#允许的请求方法
参数
除了图片数据，可以用formData设置需要额外传递的参数
$('#fileupload').fileupload({
dataType: 'json',
multipart: true,//设置为true
formData:[{name:'hello',value:'world'}]
});
服务端参考自带的server下服务端的实现代码
