Hope this would help. Assuming that you have files data in
gearsUploadedFiles array and URL in myUrl this should emulate classic form
upload:
var randomNumber = Math.floor(Math.random() * 1000000000000);
var boundary = "---------------------------" + randomNumber;
var dashDash = '--';
var crlf = '\r\n';
var dashDashBoundaryCrlf = dashDash + boundary + crlf;
var builder = google.gears.factory.create('beta.blobbuilder');
builder.append(dashDashBoundaryCrlf);
builder.append('Content-Disposition: form-data; name="fileFormat"');
builder.append(crlf);
builder.append(dashDash);
builder.append(boundary);
var item = 0;
while (gearsUploadedFiles[item]) {
builder.append(crlf);
var name = gearsUploadedFiles[item].columnId;
builder.append('Content-Disposition: form-data; name="' + name + '"');
if (gearsUploadedFiles[item].name) {
builder.append('; filename="' + gearsUploadedFiles[item].name +
'"');
}
builder.append(crlf);
builder.append('Content-Type: application/octet-stream');
builder.append(crlf);
builder.append(crlf);
builder.append(gearsUploadedFiles[item].blob);
builder.append(crlf);
builder.append(dashDash);
builder.append(boundary);
item++
}
builder.append(crlf);
// YOU CAN ADD ADITIONAL CONTET HERE IF NEEDED
builder.append(crlf);
builder.append(dashDash);
builder.append(boundary);
builder.append(dashDash);
builder.append(crlf);
gearsHttpRequest = google.gears.factory.create('beta.httprequest');
gearsHttpRequest.onreadystatechange = function(){
if (gearsHttpRequest.readyState == 1) {
// ACTION ON UPLOAD START
}
if (gearsHttpRequest.readyState == 4) {
if (gearsHttpRequest.status == 200) {
//ACTION IF SUCCESS
}
else {
// ACTION IF FAILURE
}
}
};
gearsHttpRequest.open('POST', myUrl);
gearsHttpRequest.setRequestHeader('content-type',
'multipart/form-data;boundary=' + boundary);
gearsHttpRequest.send(builder.getAsBlob());
