Unsupported media type when uploading form data to spring server
I am trying to upload a file to a remote spring server via an API, and I keep getting an unsupported media type error (415) even though I have already made the data into form data.
Here is the express http post request:
var FormData = require('form-data');
var fs = require('fs');
var form = new FormData();
form.append('pid', params.pid);
form.append('deliveryAttachment', fs.createReadStream(params.deliveryAttachment.path));
var url = someDomain + '/proj/new/deliveryAttachment';
requestLib({
url: url,
method: "POST",
jar: getJar(),
form: form
},function (error, response, body){
console.log(body)
});
And here is the Java Spring controller for reference:
@RequestMapping(value = "proj/new/deliveryAttachment", method = RequestMethod.POST, consumes = MediaType.MULTIPART_FORM_DATA_VALUE, produces = MediaType.TEXT_PLAIN_VALUE)
public String insertDeliveryAttachment(@RequestParam("pid") long pid,
@RequestParam("deliveryAttachment") MultipartFile file) {
try {
DeliveryAttachment a = new DeliveryAttachment(file.getOriginalFilename(), pid);
ps.insertDeliveryAttachment(a, file.getBytes());
return String.valueOf(a.id);
} catch (IOException e) {
return "-1";
}
}
This is the form data console log:
And the 415 response:
{
"timestamp": 1494671395688,
"status": 415,
"error": "Unsupported Media Type",
"exception": "org.springframework.web.HttpMediaTypeNotSupportedException",
"message": "Content type 'application/x-www-form-urlencoded' not supported",
"path": "/proj/new/deliveryAttachment"
}
--UPDATE--
Alright, I just found out after reading request's docs that if you use form as the holder for the data, it will treat the data as application/x-www-form-urlencoded
eg; request.post({url:'http://service.com/upload', form: {key:'value'}}, function(err,httpResponse,body){ ... });
Meanwhile the correct key for multipart/form-data is formData
eg; request.post({url:'http://service.com/upload', formData: formData}, function optionalCallback(err, httpResponse, body) { ... });
I tried it, and now it's giving me a new error:
TypeError: Cannot read property 'name' of null at FormData._getContentDisposition
It seems that you are sending a POST request with Content-Type: 'application/x-www-form-urlencoded' , and your SpringController insertDeliveryAttachment() consumes multipart/form-data mime-type.
I would recommend you to change the consumes mime-type on your insertDeliveryAttachment() method to MediaType.APPLICATION_FORM_URLENCODED_VALUE
I've solved it. I did not use FormData and just went with inserting the values inside an object and it worked.
var data = {
pid: params.pid,
deliveryAttachment: fs.createReadStream(params.deliveryAttachment[0].path)
};
var url = wfDomain + '/proj/new/deliveryAttachment';
requestLib({
url: url,
method: "POST",
headers: {
'Content-Type': 'multipart/form-data'
},
jar: getJar(),
formData: data
},function (error, response, body){ ... });
