Uploading pictures to the server

function Imgupload (names) {//upload the server's JS code
IMGURL//64 Code Image
phototime///Photo Time
custid//User ID
address//Picture Save location
for (var a=0; a<names.length;a++) {
var image = Names[a].imgurl;
var subpath= "* * *";
var name=names[a]. Custid+ "_" +names[a].phototime+ ". jpg";
var params={
image:image,/Picture Base64 Code
subpath:subpath,//Server storage Location
picname:name//file name
};
$.ajax ({//Please note the Post method using Ajax
Type: ' POST ',
url:names[a].address+ "* * *",
Data:params,
Success:success,
DataType: ' JSON '
});
}
var success = function (Resultdata) {//post-upload processing
Alert ("Upload file succeeded! ");
};
}

Background Get parameters

Import sun.misc.base64decoder;//need to configure access rules for the JRE system library

public void doget (HttpServletRequest request, httpservletresponse response) throws Servletexception, IOException {
String image = Request.getparameter ("image"). Substring (23);//Get the Base64 code of the parameter picture

The picture is stored in the location of the project at the server and then stitched to get the picture's storage location
String subpath = This.getclass (). GetResource ("/"). GetPath (). substring (1, +) + request.getparameter ("subpath");// Get Picture storage location
String picname = Request.getparameter ("Picname"). ReplaceAll ("-", "" "). ReplaceAll (": "," "). ReplaceAll (" "," ");// Get Picture Store Name
Base64decoder decoder = new Base64decoder ();//Picture base64 decrypt and save local
try {
FileOutputStream write = new FileOutputStream (new File (subpath + picname));//query picture address, create a new picture, if the address does not exist, create a new
byte[] Decoderbytes = decoder.decodebuffer (image);
Write.write (decoderbytes);
Write.close ();
} catch (IOException e) {
E.printstacktrace ();
}
}
