First of all
- You don’t need any special changes in the structure. I mean: html input tags.
<input accept="image/*" name="file" ng-value="fileToUpload"
value="{{fileToUpload}}" file-model="fileToUpload"
set-file-data="fileToUpload = value;"
type="file" id="my_file" />1.2 create own directive,
.directive("fileModel",function() {
return {
restrict: 'EA',
scope: {
setFileData: "&"
},
link: function(scope, ele, attrs) {
ele.on('change', function() {
scope.$apply(function() {
var val = ele[0].files[0];
scope.setFileData({ value: val });
});
});
}
}
})- In module with $httpProvider add dependency like ( Accept, Content-Type etc) with multipart/form-data. (Suggestion would be, accept response in json format)
For e.g:
$httpProvider.defaults.headers.post[‘Accept’] = ‘application/json, text/javascript’;
$httpProvider.defaults.headers.post[‘Content-Type’] = ‘multipart/form-data; charset=utf-8’;
-
Then create separate function in controller to handle form submit call.
like for e.g below code: -
In service function handle “responseType” param purposely so that server should not throw “byteerror”.
-
transformRequest, to modify request format with attached identity.
-
withCredentials : false, for HTTP authentication information.
in controller:
// code this accordingly, so that your file object
// will be picked up in service call below.
fileUpload.uploadFileToUrl(file);
in service:
.service('fileUpload', ['$http', 'ajaxService',
function($http, ajaxService) {
this.uploadFileToUrl = function(data) {
var data = {}; //file object
var fd = new FormData();
fd.append('file', data.file);
$http.post("endpoint server path to whom sending file", fd, {
withCredentials: false,
headers: {
'Content-Type': undefined
},
transformRequest: angular.identity,
params: {
fd
},
responseType: "arraybuffer"
})
.then(function(response) {
var data = response.data;
var status = response.status;
console.log(data);
if (status == 200 || status == 202) //do whatever in success
else // handle error in else if needed
})
.catch(function(error) {
console.log(error.status);
// handle else calls
});
}
}
