初始化一次就可以了，可以在main.dart里初始化，插件会自动管理sts token过期
后台返回sts格式：
{
"StatusCode": 200,
"AccessKeyId":"STS.iA645eTOXEqP3cg3VeHf",
"AccessKeySecret":"rV3VQrpFQ4BsyHSAvi5NVLpPIVffDJv4LojUBZCf",
"Expiration":"2015-11-03T09:52:59Z",
"SecurityToken":"CAES7QIIARKAAZPlqaN9ILiQZPS+JDkS/GSZN45RLx4YS/p3OgaUC+oJl3XSlbJ7StKpQ...."
}
加密sts返回格式：
{
"Data": "3des加密后的 sts"
}
初始化
import 'package:aliossflutter/aliossflutter.dart';
AliOSSFlutter alioss=AliOSSFlutter();
alioss.init("sts url", "http://oss-cn-hangzhou.aliyuncs.com");
//可选一种 sts token 3DES加密方式
//alioss.init("sts url", "http://oss-cn-hangzhou.aliyuncs.com",cryptkey:"key");
//监听初始化
alioss.responseFromInit.listen((data){
if(data) {
_msg="初始化成功";
}else{
_msg="初始化失败";
}
});上传
AliOSSFlutter alioss=AliOSSFlutter();
alioss.upload("bucket", file.path, "key",callbackBody: Config.callbackBody,callbackBodyType: Config.callbackBodyType,callbackHost: Config.callbackHost,callbackUrl: Config.callbackUrl,callbackVars: Config.callbackVars);
//监听上传
alioss.responseFromUpload.listen((data) {
if(data.success) {
setState(() {
_msg="上传成功 key:"+data.key+" 服务器回调返回值："+data.servercallback;
});
}else{
_msg="上传失败";
}
});下载
AliOSSFlutter alioss=AliOSSFlutter();
alioss.download(bucket, key, path,{process = ""});
//监听下载回调
alioss.responseFromDownload.listen((data) {
if(data.success) {
setState(() {
_path=data.path;
_msg="下载成功："+_path;
});
}else{
_msg="下载失败";
}
});url签名：
//type=1 签名私有资源
//type=0 签名公开的访问URL
alioss.signUrl(bucket, key,{type = "0",interval = "1800",process = ""})
//监听url签名
alioss.responseFromSign.listen((data){
if(data.success) {
setState(() {
_msg="url 签名 ："+data.url;
});
}else{
_msg="url 签名失败";
}
});监听进度上传和下载共用
alioss.responseFromProgress.listen((data){
if(data.key==key) {
setState(() {
_progress=data.getProgress();
});
}
});判断文件是否存在
alioss.exist(bucket, key).then((exist) {
if (exist) {
_msg = "已存在";
} else if (!exist) {
_msg = "不存在";
}
setState(() {});
}).catchError((err) {
_msg = "错误：$err";
setState(() {});
});写了个插件开发过程，可以参考下 插件开发方法.
