I've gone several answers on this forum as well as checking angular's documentation but for some reason I'm stuck. I'm using angular and nodejs on the backend.
Attempt 1
var config = {
//data: $.param(token.body),
data: {'message': 'Hello world'},
headers: {
"Content-Type": "application/x-www-form-urlencoded"
}
};
$http.post("/admin/SignInWithCredentials", config)
Attempt 2
$http.post("/admin/SignInWithCredentials", {message: "Hello World"})
Nodejs end I see
console.log(request.query, request.params, request.method);
{} {} 'POST'
Assuming you're using body-parser you should be expecting the POST to contain a body. Try printing out request.body.
For reference, here is what is in request.query, and here is what's in request.params. It would make sense that both of these are empty objects from the examples you've given.
You are setting arguments incorrectly... data is not part of config object
$http.post(url, data, [config]);
Reference : $http.post() docs

I'm working on app in ionic 1 platform using angularjs, in which I want to Pass List of object to Web-service, How can I do it?
I have tried doing this but was not able to send any Data..
Here is my code and how to pass list of object in data: $scope.AddNew
$http({ url: $rootScope.HostName + '/bulk', dataType: 'json', method: 'POST', contentType: "application/json; charset=utf-8", data: $scope.AddNew, headers: { 'content-type': 'application/json' } }).success(function (response) { alert("Success"); }).error(function (error) { });
If there is another approach or way to do it then please do help
Thanks in advance.
Assuming your $http call is in the controller where you can access $scope.
The way you had passed is correct, but at the server side you should accept your request body as an Array of objects.
If your server side is java spring app,
You would design your method with #RequestBody YourClass[] objs
I think your code is correct, just so it is simple and readable I would suggest this format:
$http.post($rootScope + '/bulk', $scope.AddNew).then(function(response) {
alert("Success");
}, function(error) {
})
The promise structure in AngularJS has since been updated. In regard to your question, the code should work fine if you can access AddNew through your $scope. Make sure you are handling your requests properly in the backend. Try logging for checking if data is sent and received.
Have been using $resource.save(object); to post my objects to the rest service but this time I don't want the object to be marshalled. I need it to be posted as text/plain.
Is there an easy way of doing this using angularJS?
Solved my problem.
Used the config parameters in the .save or .post functions to set the header content-types.
var config = {
headers : {
'Content-Type': 'text/plain'
}
};
$http.post(theURL, theBody, config)
Having difficulty with a temporary work around but the intent was to add to a http put request a header with string value, 'username' : 'flastname'. Within the service that invokes the put call, just before the $http.put call, the username header is to be set.
$http.defaults.headers.post.username = 'flastname';
$http.put('http://localhost:8080/xxxxx-integration/api/claims',claim);
Server side, retrieving a http header 'username' always results in null and in the even stranger behavior than expected category is random numbers of http put calls are generated. Thought I followed the documentation at:
https://docs.angularjs.org/api/ng/service/$http
but maybe read it wrong.
Have you tried the shortcut method? According to the docs, you should be able to do it like so:
put(url, data, [config]);
$http.put('http://localhost:8080/xxxxx-integration/api/claims',claim , {
headers: {'username': 'flastname'}
});
var req = {
method: 'PUT',
url: 'http://localhost:8080/xxxxx-integration/api/claims',
headers: {
'username': 'flastname'
},
data: { test: 'test' } // json for data
}
now just put the req varaible inside $http :)
$http(req).then(function()...)
WORK AROUND IS AT THE BOTTOM
Original problem
There are question like this all over the web and none of them really have answer for me. I can't get an http PATCH operation to work using angular to save my life. I've implemented $http, with shortcut $http.patch and without using the config object method:PATCH. I've used $resource by adding a custom method. And I've implemented Restangular using their patch and I'm getting the same error. I have the correct Content-Type as suggested in other posts. I think it's safe to say at this point, it's something I'm missing. I'm getting the same "404" message via postman when trying to patch. I can PUT, GET, POST, and DELETE, but not PATCH.
In the following images you can see that the resource exists for GET. But when trying to patch I get 404. Browsing to that endpoint shows the record. Which is stored in Mongodb.
Here's some code snippets:
Resangular GET:
var corporiumRecord = Restangular.one('corporium-mgmnts', $scope.uuid);
corporiumRecord.get().then(function(res) {
console.log(res)
}, function(err) {
console.log('Restangular failed: ', err)
});
Restangular Patch:
var data = {
corporiumId: $scope.newBlock
};
var corporiumRecord = Restangular.one('corporium-mgmnts', $scope.uuid);
corporiumRecord.patch(data).then(function(res) {
console.log(res)
}, function(err) {
console.log('Restangular failed: ', err)
});
$http attempt using config object:
controller code:
httpCorporiumSrv.updateCorporiumId('/corporium-mgmnts/' + $scope.params.id, data)
.then(handleUpdateSuccess)
.catch(handleUpdateError);
service code, tried forcing the content-type header but got same result
with or without it:
function updateCorporiumId(url, data) {
return $http({
method: 'PATCH',
url: url,
data: angular.toJson(data),
headers: {
'Content-Type': 'application/json;charset=utf-8'
}
//transformRequest: transformUpdateData
})
.then(handleUpdateSuccess)
.catch(handleUpdateErrors);
}
Using the .patch shortcut:
function updateCorporiumId(url, data) {
return $http.patch(url, data, {
transformRequest: transformUpdateData
})
.then(handleUpdateSuccess)
.catch(handleUpdateErrors);
}
Thing is I've tried this every which way I know how. I don't even know how to start debugging any more. I'm just getting 404 on a resource that does exist. Any suggestions on what might be happening to my request would be great.
Resolution:
For anyone having this issue, if you could post the fix or what's going on here to this point or PM me that would be awesome I'd like to know. I ended up just using PUT to fix this.
Quick Restangular solution:
Build the url template for findByOne like function using Restangular.one(url, _id) where '_id', is the id of the resource you're looking for. .get() goes out and finds that one resource by said id, which you can populate dynamically however you like. Once you have the one resource with GET copy it with Restangular.copy() which is different from angular.copy as it doesn't bind 'this' to the new object. Change what needs to be changed or added in the new object and then perform a .put() on it.
var corporiumRecord = Restangular.one('corporium-mgmnts', $scope.uuid);
corporiumRecord.get().then(function(res) {
var update = Restangular.copy(res);
// update date corporiumId
update.corporiumId = $scope.newBlock;
// submit new doc with altered value
update.put().then(function() {
console.log('updated')
});
console.log(update)
}, function(err) {
console.log('Restangular failed: ', err)
});
Also because mongo uses _id and Restangular uses id you have to add this to your module
angular.module('corporium-mgmnts').config(function(RestangularProvider) {
RestangularProvider.setMethodOverriders(['put', 'patch']);
// setRestangularFields is required for mongodb
RestangularProvider.setRestangularFields({
id: "_id"
});
});
I'm a beginner. I've written a test application made of an AngularJs GUI on the client side and a PHP API on the server side.
This is the angular service handling the requests
myApp.factory('Book', ['$resource', 'API_URL', function($resource, API_URL){
return $resource(API_URL + '/books/:bookId', {bookId: '#bookId'}, {
get: { method: 'GET', isArray:true },
update: { method: 'PUT'},
save: { method: 'POST'},
delete: {method:'DELETE'},
});
}]);
When I submit a book from the Angular app I can catch the POST in Slim by using
$post_a = json_decode($app->request->getBody());
//$post_b = $app->request->post(); //this would be empty
When I use Postman and I perform a POST I can catch the POST in Slim by using
//$post_a = json_decode($app->request->getBody()); // this would be empty
$post_b = $app->request->post();
I don't get why there is this difference. Could you please explain?
Am I not meant to catch the post just with $app->request->post(); in both the cases? Why the post coming from Angular can be caught only with $app->request->getBody()?
The $app->request->post() method retrieves key/value data submitted in a application/x-www-form-urlencoded request. If the request uses a different content-type (e.g. application/json), you can retrieve the raw request body with the $app->request->getBody() method and decode it as necessary. Let me know if you have further questions.
You could still use
$post_b = $app->request->post()
in Slim.
As long as you call this REST service from html form (AngularJS) by passing the data as form value formatted instead of as JSON.
If in AngularJS you have the data in JSON format, you have to translate it first into form. Below is the example how to invoke this REST service:
Object.toparams = function ObjecttoParams(obj) {
var p = [];
for (var key in obj) {
p.push(key + '=' + encodeURIComponent(obj[key]));
}
return p.join('&');
};
$http({
method: 'POST',
url: url,
data: Object.toparams(myobject),
headers: {'Content-Type': 'application/x-www-form-urlencoded'}
})
myobject is the data in JSON format that is going to be created
Thanks Josh..Your answers works for me.
Steps to follow:
1.You need to send request in json format under raw tab like this:
{"username":"admin","password":"admin"}
2.You need to set Content-Type to application/json in the headers.
That's it and it will work.
