I'm trying to process the response headers but not sure how to query for them. Here's the code snippet. I commented out a couple of lines when I attempted to read the headers and put some comments on what I noticed.
$http({
method: 'POST',
url: URL,
data: $.param(data),
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
})
.success(function (data,status,headers) {
//Need to process the header to understand the server response
//console.log(headers()); //This returns null
//console.log(headers('custom-myapp-text');// Obvisouls returns null as the headers() returns null
deferred.resolve();
});
return deferred.promise;
};
As per their documentation, the 'headers' returns a function?? Not sure how to query for header values based on this.
data – {string|Object} – The response body transformed with the
transform functions.
status – {number} – HTTP status code of the response.
**headers – {function([headerName])} – Header getter function.**
config – {Object} – The configuration object that was used to generate the request.
statusText – {string} – HTTP status text of the response.
I just tried it with a valid header and it was fine:
console.log(headers('Content-Length'));
This console logged 2 in my example. It will allow you access to any of the valid response headers.

I use Vuejs to create my frontend for my project.
At the creation of one component ('TimeCapsy.vue'), I make an AJAX call to my backend like this:
created: function () {
if (verify.verify_login()) {
let token = this.$cookies.get('jwt_us_cas');
let params = {'jwt': token};
console.log(params);
axios({
method: 'post',
url: dev.HOST+'getuserinfoobject',
params: queryString.stringify(params)
})
.then(response => {
console.log(response.data)
})
}
}
As you can see I use the
this.$cookies.get('jwt_us_cas');
to get the a json web token, that I set on the client at the login.
I use the queryString Library to stringify my parameters for my request.
I also tried it without the queryString.stringify(params) call, but I get the same error, e.g. the parameter still turns into null.
When I look at the console log, where I check the params variable, I get this output:
{jwt: "my token comes here"}
So I can see, that it gets the correct value from the cookie.
But when I check the answer from my backend (PHP), I get this error:
Undefined index: jwt in <b>D:\casb\public\index.php</b> on line <b>52</b>
Of course I know that it means, that jwt is null, but I can't understand why.
As I said, right before I make the call I check the params and it shows the token.
I checked the endpoint with Postman and the token as the jwt parameter and it returned a successfull call with the correct answer.
A correct answer is basically just a nested object with some information in it.
My PHP endpoint is pretty basic too:
Router::add('/getuserinfoobject', function () {
$response['response'] = User::getUserInfoObject($_POST['jwt']);
echo json_encode($response);
}, 'post');
So I guess that right before or in my call it nulls my parameter. But I can't understand how, since I make a lot of requests and never had this problem.
From axios docs
params are the URL parameters to be sent with the request
Which means, you should get the value with PHP $_GET.
Or $_REQUEST (which stores both $_GET, $_POST. Also $_COOKIE).
The other hand, you can use data key as docs says
data is the data to be sent as the request body
Only applicable for request methods PUT, POST, and PATCH
So the value would be available in $_POST
axios({
method: 'post',
url: dev.HOST+'getuserinfoobject',
data: {
jwt: token
}
})
There is a URL I am using in a project of mine, that is working just fine. I make a request from one web server, to a different IP address, invoking a page that outputs data in this format:
[{"PhoneNumber":"+123456789","Name":"Mark"},
{"PhoneNumber":"+123456789","Name":"Josh"},
{"PhoneNumber":"+123456789","Name":"Alex"},
{"PhoneNumber":"+123456789","Name":"John"},
{"PhoneNumber":"+123456789","Name":"Sean"}]
And I can get and process that data with a function call such as this:
$.ajax({
url: serverAddress + "/getpeople",
dataType: "jsonp",
timeout: 4000,
success: function(response) {
for(var i in response) {
alert(response[i].Name);
}
}
});
Here is what's confusing me. From what I've learned about JSONP so far, it isn't actually data, but is instead a function. So the response should be wrapped in a function call, such as callback(), and then I could implement a function callback(data) {} in my project to process the data.
But in this case, the data seems to be just JSON data, which I think should cause a cross-origin error to be generated? But it doesn't.
When I try to call another URL from the same server, fetching an ordinary plain text file, then I do get a cross-origin error, which complains in the console:
Reason: CORS header 'Access-Control-Allow-Origin' missing
But the original getpeople URL does not have that header either. When I examine the response headers in Firefox's document inspector, all of the headers are:
Connection: "close"
Content-Type: "text/html;charset=utf-8"
Date: "Mon, 5 Oct 2015 08:29:07 GMT"
Server: "ServerName/1.1.10011.2211"
So:
The data is not formatted as a JSONP callback
It is served from a different IP address than the web application
The response doesn't have a Access-Control-Allow-Origin header
Why does this work?
My server give response header authorization bearer.
How can I get this value in angular?
When you use $http, the third parameter of the promise callback contains the response headers. You should be able to get your header from there.
With the $http service you can receive the headers through the success functions response object. You can access this property through
$http(....).success(function(result, status, headers, config){
var myAuthHeader = headers("myAuthorizationHeader");
... Do something with your headers....
}
})
I am new to Django.I am sending a ajax POST request to a python function which in turn stores the data in the variables from the ajax and return the HttpResponse .So i checked request.method in python its coming as GET.
$.ajax({
url:"create_post/",
type:"POST",
data : {F_Name: First_Name ,L_Name: Last_name,Eadd: Email , Password: Pass},
success:function(){
window.location.href="create_post/";
console.log ("Success")
},
cache:false,
failure: function(errMsg) {
alert(errMsg);
}
});
this is my ajax request.
its sending the data to this function .
def create_post(request):
if request.method == 'GET':
First_name=request.GET['F_Name'];
Last_Name=request.GET["L_Name"];
Email_address=request.GET["Eadd"];
Pass=request.GET["Password"];
return HttpResponse("<html><body>hi this is me .</body></html>");
When I checked as return(request.method) its giving me GET.
Can some one explain this behavior?
And in the function i have request.method==GET in this scenario DJango is giving me internal server 500 error.
Thanks
I am surprised to see that none of you didn't noticed that he has define method: "POST" in his ajax and his function is used on "GET" request.
And the main reason he is getting the output for print request.method = "GET" and 500 error is because of using window.location.href="create_post/" in his ajax success function. Every request is by default a get request unless we explicitly define it "POST" or any other.
So here it goes like this,
- Ajax calls the url via POST, for unknown reason the response comes in success function(weird coz according to the view posted POST method return nothing to ajax request).
- The success function again calls the same url(page refresh) via a GET request and he sees print request.method as "GET" with 500 error coz this is wrong way to do so.
your ajax method is post, so i think your views.py may try this
def create_post(request):
if request.method == 'POST':
First_name=request.POST['F_Name']
Last_Name=request.POST["L_Name"]
Email_address=request.POST["Eadd"]
Pass=request.POST["Password"]
return HttpResponse("<html><body>hi this is me .</body></html>")
again, I got another problem with casperjs, now with sendAJAX function.
It says that sendAJAX has 5 parameters which are these followings :
url: The url to request.
method: The HTTP method (default: GET).
data: Request parameters (default: null).
async: Flag for an asynchroneous request? (default: false)
settings: Other settings when perform the AJAX request (default:
null)
So, it says the data method is object so, it should be filled with :
var data = new Object();
data.amount= 15;
and also with this one,
var data = {amount:15};
but there were no successful value send to my web service (always send 0 as value, but ajax request successful, even returning the json data) which has an url like this
"http://localhost:9000/TempCountryAmountREST/setCountryAmount"
It will be succeed if I direct bind my data variable to my url like this :
"http://localhost:9000/TempCountryAmountREST/setCountryAmount?amount="+amount
[UPDATE]
The TempCountryAmountREST is my controller name and setCountryAmount is my function inside my controller.
[UPDATE]
I forgot to include my usage of sendAJAX(), here is the code that I use :
return JSON.parse(__utils__.sendAJAX(wsurl, "POST" , data, false, { contentType: "application/json" }));
So how does I fill the data in the sendAJAX parameter?
Thanks in advance...
Sorry, I've found what the answer is.
I make some mistakes in contentType which I was set with contentType: "application/json" instead of contentType: "application/x-www-form-urlencoded" }
If we are looking about how ajax send the content from method send(), they were use x-www-form-urlencoded. See this for more detail
When we see through casperjs clientutils.js script, we should found how sendAJAX work.
On the `this.sendAJAX = function sendAJAX(url, method, data, async, settings) {
}
there are url construction logic which transformed our Object (if so) to x-www-form-urlencoded form. So that we need to set our contentType as application/x-www-form-urlencoded
Very well, thanks for your attention...
