java获取网络图片上传到OSS的方法
OSS不支持通过一个网络地址来上传图片，所以若想将网络上的图片上传到OSS上需要走点弯路。
1、通过链接将图片下载到本地的一个文件夹下面
2、用OSS上传该文件夹下的文件
3、上传完成后删除本地的文件
具体代码如下：
//获取当前项目的绝对路径
publicstaticStringgetTomcatPath(){
Stringnowpath;
Stringtempdir;
nowpath=System.getProperty("user.dir");
tempdir=nowpath.replace("bin","");//把bin文件夹变到webapps文件里面
returntempdir;
}
/**
*将图片下载下来后，上传到OSS
*@paramimgLink
*@paramdownloadPath
*@return
*@throwsException
*/
privateStringdownloadImagAndUploadToOss(StringimgLink,StringdownloadPath)throwsException{
ListurlList=newArrayList();
urlList.add(imgLink);
StringimgName=DateUtil.formatDate(newDate(),"yyyyMMddhhmmss")+UuidUtil.createUUID()+".jpg";
downloadPicture(urlList,downloadPath,imgName);
Stringkey="carAlbum/"+imgName;
StringimgUrl=OSSObjectAPI.genOssPicUrl(OSSObjectAPI.XI_AN_BUCKET_NAME,OSSObjectAPI.XIAN_ACCESS_ID,OSSObjectAPI.XIAN_ACCESS_KEY,
"http://oss-cn-zhangjiakou.aliyuncs.com/",downloadPath+imgName,key);
FileUtil.delete(downloadPath+imgName);
returnimgUrl;
}
/**
*传入要下载的图片的url列表，将url所对应的图片下载到本地
*@paramurlList
*@throwsException
*/
privatevoiddownloadPicture(ListurlList,Stringpath,StringimgName)throwsException{
if(urlList==null||urlList.size()==0){
return;
}
URLurl=null;
FileOutputStreamfileOutputStream=null;
InputStreaminputStream=null;
for(StringurlString:urlList){
try{
url=newURL(urlString);
HttpURLConnectionconnection=(HttpURLConnection)url.openConnection();
connection.addRequestProperty("User-Agent","Mozilla/5.0(WindowsNT6.1;WOW64;rv:55.0)Gecko/20100101Firefox/55.0");
connection.setConnectTimeout(10*1000);
connection.setReadTimeout(15*1000);
inputStream=connection.getInputStream();
byte[]buffer=newbyte[1024];
intlength;
fileOutputStream=newFileOutputStream(path+File.separator+imgName);
while((length=inputStream.read(buffer))!=-1){
fileOutputStream.write(buffer,0,length);
}
}catch(Exceptione){
e.printStackTrace();
}finally{
inputStream.close();
fileOutputStream.flush();
fileOutputStream.close();
}
}
}
