I have an HTML form that needs to upload 3 parts to an existing REST API in a single request. I can't seem to find documentation on how to set a boundary on a FormData submission.
I've attempted to follow the examples given here: How to send FormData objects with Ajax-requests in jQuery?
However when I submit the data it gets rejected with the following stacktrace:
Caused by: org.apache.commons.fileupload.FileUploadException: the request was rejected because no multipart boundary was found.
How can I set a boundary?
Here is the HTML/Javascript:
<script type="text/javascript">
function handleSubmit() {
var jsonString = "{" +
"\"userId\":\"" + document.formSubmit.userId.value + "\"" +
",\"locale\":\"" + document.formSubmit.locale.value + "\"" +
"}";
var data = new FormData();
data.append('Json',jsonString);
data.append('frontImage', document.formSubmit.frontImage.files[0]);
data.append('backImage', document.formSubmit.backImage.files[0]);
document.getElementById("sent").innerHTML = jsonString;
document.getElementById("results").innerHTML = "";
$.ajax({
url:getFileSubmitUrl(),
data:data,
cache: false,
processData: false,
contentType: 'multipart/form-data',
type:'POST',
success:function (data, status, req) {
handleResults(req);
},
error:function (req, status, error) {
handleResults(req);
}
});
}
</script>
Here is the Form:
<form name="formSubmit" action="#">
userId: <input id="userId" name="userId" value=""/><br/>
locale: <input name="locale" value="en_US"/><br/>
front Image: <input type="file" name="frontImage"/><br/>
back Image: <input type="file" name="backImage"/><br/>
<input type="button" onclick="handleSubmit();" value="Submit"/>
</form>
Thanks in advance for any help!
Musa's response worked great. Setting the contentType to false did submit the form data correctly. THANKS!
Here is the ajax call that worked:
$.ajax({
url:getFileSubmitUrl(),
data:data,
cache:false,
processData:false,
contentType:false,
type:'POST',
success:function (data, status, req) {
handleResults(req);
},
error:function (req, status, error) {
handleResults(req);
}
});
I also found that this code also worked:
var oReq = new XMLHttpRequest();
oReq.open("POST", getFileSubmitUrl());
oReq.addEventListener("error", transferComplete);
oReq.addEventListener("load", transferComplete);
oReq.addEventListener("abort", transferComplete);
oReq.send(data);
}
function transferComplete(evt) {
handleResults(evt.target);
}
