Read Uploaded Vcf File From Server

I have uploaded vcf file successfully on server on getting help from my previous question (the one which is edited) Now I need a help in how to read that vcf file or vcard from ser

Solution 1:

Using plugin cordova-plugin-file-transfer https://github.com/apache/cordova-plugin-file-transfer you can download file from server.

For Read vcf file, you need https://github.com/nilclass/vcardjs JavaScript based library. you can directly use .js files.

You can follow below example.

window.requestFileSystem(window.TEMPORARY, 1 * 1024 * 1024, function (fs) {

        console.log('file system open: ' + fs.name);
        var fileName = "temp.vcf";
        var dirEntry = fs.root;
        dirEntry.getFile(fileName, { create: true, exclusive: false }, function (fileEntry) {

           download(fileEntry,"server-path-to-file.vcf");

        }, onErrorCreateFile);

    }, onErrorLoadFs);




functiondownload(fileEntry, uri) {

    var fileTransfer = newFileTransfer();
    var fileURL = fileEntry.toURL();

    fileTransfer.download(
        uri,
        fileURL,
        function (entry) {
            console.log("Successful download...");
            console.log("download complete: " + entry.toURL());
            readFile(entry);
        },
        function (error) {
            console.log("download error source " + error.source);
            console.log("download error target " + error.target);
            console.log("upload error code" + error.code);
        },
        null, // or, pass false
        {
            //headers: {//    "Authorization": "Basic dGVzdHVzZXJuYW1lOnRlc3RwYXNzd29yZA=="//}
        }
    );
}


functionreadFile(fileEntry) {
    fileEntry.file(function (file) {

        var reader = newFileReader();

        reader.onloadend = function () {

            console.log("Successful file read: " + reader.result);
            reader.parseVCard(reader.result);

        };

        reader.readAsText(file);

    }, onErrorReadFile);
}

functionparseVCard(vCarddata){
VCF.parse(vCarddata, function(vcard) {
  // this function is called with a VCard instance.// If the input contains more than one vCard, it is called multiple times.console.log("Formatted name", vcard.fn);
  console.log("Names", JSON.stringify(vcard.n));
});
