Fake path Javascript Issue - javascript

When I try to retrieve the File path it's shows me the result like this: "C:\fakepath\amine.jpeg" so the upload in the server is not working as a result of that problem.
$('input[type=file]').change(function () {
var filePath=$('#file-input').val();
$.ajax({
url : "{{path('upload_file')}}",
type : 'POST',
data: {
filePath : filePath,
method: 'post',
params: {
action: "uploadFile"
}
},
success : function(data, textStatus, jqXHR) {
alert(data);
}
});
});

You are doing this all wrong.
You have to create a form object and send it via $.ajax.
And I assume you have written the correct serverside code to save the image.
var f = new FormData();
f.append('img',document.getElementById("file-input").files[0]);
var url= "{{Your URL}}";
$.ajax({
url: url,
type:"post",
data: f,
dataType:"JSON",
processData: false,
contentType: false,
success: function (data, status)
{
console.log(data);
},
error: function (data)
{
if (data.status === 422) {
console.log("upload failed");
} else {
console.log("upload success");
}
});

Your file by default upload to a temporary folder. You need to move it to an actual location to get access to it like in php:
move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $target_file)
For reference, see http://www.w3schools.com/php/php_file_upload.asp

How to fetch object from aws s3 using ajax get rest api

I have a file named 3514706-ironmanvr-promo-nologo.jpg in my s3 bucket and I am trying to download the file using javascript rest api, here is my code
var jqxhr = $.ajax({
url: "https://s3.amazonaws.com/asif.test/3514706-ironmanvr-promo-nologo.jpg",
type: "GET",
async: true
})
.done(function (data, textStatus, jqXhr) {
console.log(data);
})
.fail(function (jqXhr, textStatus, errorThrown) {
console.log(errorThrown);
if (errorThrown === "abort") {
alert("Uploading was aborted");
} else {
alert("Uploading failed");
}
})
.always(function (data, textStatus, jqXhr) { });
but in data I am getting garbage values like this
response image
I don't know how to deal with this.
I was having the exact same issue, and after much digging and hair-removal I came across this answer:
https://medium.com/#timleland/set-image-src-from-amazon-s3-2232d246bebd
It solved it for me; the article says:
"Since Jquery ajax does not support the responseType: ‘blob’, you have to set the value in the xhrFields. The other important part is to use window.URL.createObjectURL to convert the blob to a url for the image src."
var loadImage = function (imageUrl) {
$.ajax({
type: 'GET',
url: imageUrl,
dataType: null,
data: null,
xhrFields: {
responseType: 'blob'
},
success: function (imageData) {
var blobUrl = window.URL.createObjectURL(imageData);
$('#image-id').attr('src', blobUrl);
}
});
};

Post AJAX API Javascript SAPUI5 failed

I want to use POST method with AJAX in SAPUI5 javascript but I found an error.
var url = "https://xxxx*xxxx.co.id:8877/TaspenSAP/SimpanDosirPunah";
$.ajax({
type: "POST",
url: url,
data: JSON.stringify({
nomorDosir: "01001961288",
kodeCabang: "A02"
}),
dataType: "json",
async: false,
contentType: 'application/json; charset=utf-8',
success: function(data, textStatus, xhr){
console.log("sukses: " + data + " " + JSON.stringify(xhr));
},
error: function (e,xhr,textStatus,err,data) {
console.log(e);
console.log(xhr);
console.log(textStatus);
console.log(err);
}
});
error:
I already did change code with dataType=text, or data: {nomorDosir: "01001961288", kodeCabang: "A02"} (without stringify), but I not yet find the solution. How to fix this problem?
Thanks.

Not sure what your use case is but if you are trying to post to an oData service, it might be much easier to use SAPs createEntry method where the URL is the path to the model you want to post to and your JSON are the properties:
var oModel = new sap.ui.model.odata.v2.ODataModel("https://services.odata.org/V2/OData/OData.svc/");
//oModel should use your service uri
var url = "https://xxxx*xxxx.co.id:8877/TaspenSAP/SimpanDosirPunah";
oModel.createEntry(url, {
properties: {
nomorDosir: "01001961288",
kodeCabang: "A02"
}
}, {
method: "POST",
success: function(response) {
alert(JSON.stringify(response));
//do something
},
error: function(error) {
alert(JSON.stringify(error));
}
});
oModel.submitChanges();
What you have is wrong json format, you have:
data: JSON.stringify({nomorDosir: "01001961288", kodeCabang: "A02"}),
Which actually should be:
data: {"nomorDosir": "01001961288", "kodeCabang": "A02"},
Which then you don't need to do a json.stringify on, because it already IS a json format. Hope this will help you out.
Which you could also try is setting a variable outside like this:
var url = "https://xxxx*xxxx.co.id:8877/TaspenSAP/SimpanDosirPunah";
var json = {"nomorDosir": "01001961288", "kodeCabang": "A02"};
$.ajax({
type: "POST",
url: url,
data: json,
dataType: "json",
async: false,
contentType: 'application/json; charset=utf-8',
success: function(data, textStatus, xhr){
console.log("sukses: "+data+" "+JSON.stringify(xhr));
},
error: function (e,xhr,textStatus,err,data) {
console.log(e);
console.log(xhr);
console.log(textStatus);
console.log(err);
}
});

Web service receiving null with jQuery post JSON

The web service on http://localhost:57501/api/addDatabase has the following code.
[System.Web.Mvc.HttpPost]
public ActionResult Post(addDatabase pNuevaConeccion)
{
pNuevaConeccion.insertarMetaData();
return null;
}
The Ajax function is on a javascript that creates the JSON from the give values on http://localhost:1161/CreateServer.
$(document).ready(function ()
{
$("#createServer").click(function (e) {
e.preventDefault(); //Prevent the normal submission action
var frm = $("#CreateServerID");
var dataa = JSON.stringify(frm.serializeJSON());
console.log(dataa);
$.ajax({
type: 'POST',
url: 'http://localhost:57501/api/addDatabase/',
contentType: 'application/json; charset=utf-8',
crossDomain: true,
//ContentLength: dataa.length,
data: dataa,
datatype: 'json',
error: function (response)
{
alert(response.responseText);
},
success: function (response)
{
alert(response);
if (response == "Database successfully connected") {
var pagina = "/CreateServer"
location.href = pagina
}
}
});
});
});
When I run this code an alert pops up saying "undefined" but if I delete the contentType the alert doesn't show up. The problem is that the variables that the function Post (from the web service) receives are NULL even though I know that the JSON named dataa is not NULL since I did a console.log.
I have seen various examples and pretty much all of them say that I should use a relative URL but the problem is that since there are 2 different domains and when I tried it, it couldn't find the URL since it's not in the same localhost.
Web service should return a JSON format instead of null. like below example.
public JsonResult Post()
{
string output = pNuevaConeccion.insertarMetaData();
return Json(output, JsonRequestBehavior.AllowGet);
}
try to use this code for calling the web method
$.ajax({
method: "POST",
contentType: "application/json; charset=utf-8",
data: dataa,
url: 'http://localhost:57501/api/addDatabase/',
success: function (data) {
console.log(data);
},
error: function (error) {
console.log(error);
}
});
its my old code.(ensure action parameter variable name and post variable name are same)
$('#ConnectionAddres_ZonesId').change(function () {
var optionSelected = $(this).find("option:selected");
var id = { id: optionSelected.val() };
$.ajax({
type: "POST",
url: '#Url.Action("GetParetArea", "Customers")',
contentType: "application/json;charset=utf-8",
data: JSON.stringify(id),
dataType: "json",
success: function (data) {
$('#ConnectionAddres_ParentAreaId').empty().append('<option value="">Select parent area</option>');
$.each(data, function (index, value) {
$('#ConnectionAddres_ParentAreaId').append($('<option />', {
value: value.Id,
text: value.Area
}));
});
},
});
});
public ActionResult GetParetArea(int id)
{
var parents="";
return Json(parents, JsonRequestBehavior.AllowGet);
}

jQuery Submit Form (w/ file and text) without redirecting from current window

I want to build an application form where on can attach an image - it's just a couple of input elements - within a div (not an form element). The form shall be processed without an page redirect. So I use ajax. Everything works fine so far. But now I need to add an image.
$('#submit_application').click(function () {
//...
$.ajax({
url: 'submit.php',
type: 'post',
data: {
'action': 'submit',
'image': $('#image_upload').val(),
// ..
'someStringifiedJSON': JSON.stringify(foo)
},
success: function (data, status) {
// ...
},
error: function (xhr, desc, err) {
// ...
}
});
});
How can I get my file into php's $_FILES variable? Or how can I pass the file to php so that I can upload it?
you can send files using formData.
var file = $('#image_upload')[0].files[0];
var fData = new FormData();
fData.append('action', 'submit');
fData.append('image', file);
fData.append('someStringifiedJSON', JSON.stringify(foo));
and your ajax request will be:
$.ajax({
url: 'submit.php',
type: 'post',
data: fData ,
contentType: false,
processData: false,
success: function (data, status) {
// ...
},
error: function (xhr, desc, err) {
// ...
}
});
Explanation:
as specefied here.if you set processData to true it will pass it as query string.if you want to send non-processed data set it to false.
default for contentType is application/x-www-form-urlencoded; charset=UTF-8.which won't work for files (because it sends heder like multipart/form-data; boundary=---------------------------125911542220235) when you set it to false browser generate right content-type header automatically
Try this:
$('#submit_application').click(function () {
var formData=new FormData();
formData.append('action','submit');
formData.append('someStringifiedJSON', ''+JSON.stringify(foo));
formData.append($('#image_upload').files[0]);
$.ajax({
url: 'submit.php',
type: 'post',
contentType:false,
data: formData,
success: function (data, status) {
// ...
},
error: function (xhr, desc, err) {
// ...
}
});
});
Make sure to add this contentType:false in ajax request.

Post JSON data along with id in Jquery AJAX

I'm trying to post JSON data along with 2 ids through a Jquery AJAX post. But I am not able to do it.
Following is my code:
try {
var surveyID= localStorage.getItem("surveyId");
var userDetails = jQuery.parseJSON(localStorage.getItem("userdetails"));
var providerKey = userDetails["ProviderUserKey"];
var dataValue = { "str": StringJson};
var url = APP_URL+"EditSurvey?";
var param = "SurveyId="+surveyID+"&JSONData="+JSON.stringify(dataValue)+"&UserId="+providerKey;
$.ajax({
type: "POST",
contentType: "application/json",
url: url,
data: param,
async:true,
success: function (data) {
alert('sucess');
//}
},
error: function (err) {
alert("Err : " + err.error);
},
});
} catch (error) {
alert(error);
}
I get the following error when I debug this in Safari:
Failed to load resource: the server responded with a status of 500 (Internal Server Error)
and in simulator I get the following error:
Where am I getting wrong? How do I solve this? I have to 3 parameters for post
surveyID
JSON data
userID
Edited:
The webservice is now changed and all 3 params- i.e. 2 ids and one whole json data is passed to the webservice. Still jquery ajax post is not working. See my code below:
var surveyID= localStorage.getItem("surveyId");
var userDetails = jQuery.parseJSON(localStorage.getItem("userdetails"));
var providerKey = userDetails["ProviderUserKey"];
var dataValue = {"surveyID":surveyID, "userID":providerKey, "str": StringJson};
alert(dataValue);
var url = APP_URL+"EditSurvey";
var param = dataValue;
$.ajax({
type: 'POST',
contentType: "application/json",
url: url,
data: dataValue,
success: function (data) {
alert('sucess');
//}
},
error: function (err) {
alert("Err : " + err.text);
},
});
edited to include stringJson:
var StringJson = JSON.stringify(MainJSON);
alert(StringJson);
Check if the final json which is being passed is in the exact format as expected by the server.
Try giving:
contentType: 'application/json',
Accept: 'application/json'
See if it helps.
try this one
formData = {
// all your parameters here
param1: param1,
JSONData: formToJSON(),
UserId: providerKey
}
$.ajax({
type: 'POST',
contentType: 'application/json',
url: url,
dataType: "json",
data: formData,
success: function(data) {
//success handling
},
error: function(data) {
alert("Err : " + err.error);
}
});
function formToJSON() {
return JSON.stringify({
dataValue: dataValue
});
}
