目前已测上传支持格式:{".rar", ".doc", ".docx", ".zip",
".pdf", ".txt", ".swf", ".xlsx", ".gif", ".png", ".jpg", ".jpeg",
".bmp", ".xls", ".mp4", ".flv", ".ppt", ".avi", ".mpg", ".wmv",
".3gp", ".mov", ".asf", ".asx", ".vob", ".wmv9", ".rm", ".rmvb"{
允许视频转码的格式:{ ".wmv9", ".rm", ".rmvb" }
如需上传多文件,后台需要使用MultipartFile[] 数组接收,然后for循环fileUploadTool.createFile,多文件上传未做测试,有需要的小伙伴自行测试。
1,前端代码
function testUploadVideo(){
var fileObj = document.getElementById("file").files[0]; //获取文件对象
var formFile = new FormData();
formFile.append("param", "100"); //传入需要传的参数
formFile.append("file", fileObj); // 加入文件对象
var data = formFile;
$.ajax({
url : "../../lecture/uploadflv/uploadSave.action",
type : "post",
data : data,
cache : false,// 上传文件无需缓存
processData : false,// 用于对data参数进行序列化处理 这里必须false
contentType : false, // 必须
success : function(res) {
alert("生成成功");
alert(JSON.parse(res).result); //接收前台返回json字符串
},
error : function() {
alert("生成失败");
}
})
}
