I'm quite new with ANGULAR and web development in general and I'm currently working on a web tool. Now I want this tool to send a POST request to a web service but Im encountering a weird bug. Now I have below code in my javascript:
var data_info = { test_id: 'TEST', model_id: 'TEST:TEST_ID' };
//data_info = JSON.stringify(data_info);
var request_json = {
method: 'POST',
url: url,
headers: {
'Content-Type': 'application/json',
'Accept': 'application/json'
},
data: data_info,
cache: false,
};
console.log(request_json);
$http(request_json).then(function successCallback(response) {
// response code here
}
Now this code currently doesn't pass the preflight request check and is always returning a 405. But if I change the line data: data_info in the request JSON into a new key let's say body: data_info it now successfully sends the request and I can confirm that the service is receiving it. I'm not sure what's the issue here and can't figure it out.
change your header to :
headers : {
'Content-Type': 'application/x-www-form-urlencoded;charset=utf-8;'
}
Please try

I am trying to call a POST request in ReactJs using Axios, but getting an error. Code:
const payload =
{
device_id: 'ASDACCAS',
device_type: 'Web',
device_version: '1.2',
device_user_id: 'ASDBADKKK1234AS'
}
axios({
method: 'post',
url: 'https://stageapi.myapi.com/v3_2/user/splash',
data: payload,
headers: {
'secret-key': 'mysecretkey',
'Content-Type': 'application/json'
},
})
But this is giving me error:
Failed to load https://stageapi.myapi.com/v3_2/user/splash: Response for preflight does not have HTTP ok status.
Kindly help me whats wrong here. I am new to ReactJS and moving from mobile app development environment. I have been on this for so long, tried every method for axios POST including by appending formdata to body. Still the same.
EDIT:
Also, I am not sure if its something related to CORS. I have installed the the CORS plugin in chrome. Are there any changes that I need to make in API side code? Which is written in php.
When you want to make a post request, you need to stringify body request like this:
axios({
method: 'post',
url: 'https://stageapi.myapi.com/v3_2/user/splash',
data: JSON.stringify(payload),
headers: {
secret-key': 'mysecretkey',
'Content-Type': 'application/json'
},
})
axios.post('https://stageapi.myapi.com/v3_2/user/splash',
payload,
headers: {
'secret-key': 'mysecretkey',
'Content-Type': 'application/json'
}
})
.then((response) => {
console.log(response.data);
});
I'm facing problem with CORS requests in AngularJS while calling web services but the same service able to call by using jQuery.
Note: From server side we are receiving header "Access-Control-Allow-Origin:*" and these services are running fine in jQuery application.
Here I'm posting my AngularJS code as well as jQuery code.
AngularJS:
$http({
method: 'POST',
url: $rootScope.host + "UserLogin",
//headers: { 'Content-Type': 'application/x-www-form-urlencoded' },
data: {
"uname": $scope.uname,
"password": $scope.password
},
}).then(function (success) {
$scope.loginDetails = success;
console.log($scope.loginDetails);
}),function (error){
console.log(error);
});
If I pass the header like headers: { 'Content-Type': 'application/x-www-form-urlencoded' } able to ping the service but my request is not going in JSON format.
If I change the header to 'Content-Type': 'application/json', getting
XMLHttpRequest cannot load https://XXXX.XXXX.in/XXXXAPI/UserLogin.
Response to preflight request doesn't pass access control check:
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://170.11.0.61' is therefore not allowed access.
I don't know what is the reason for this error.
$.ajax({
url: BASE_URL + "UserLogin",
type: "POST",
xhrFields: {withCredentials: true},
data: {
"uname": uname,
"password": password
},
cache: false,
success: function (result, textStatus, request) {
console.log(result);
},
error: function (e) {
console.log("Error in login service call:"+JSON.stringify(e));
}
});
This jQuery is sending my request in the json format.
Try to pass headers like
headers: { 'Content-Type': 'application/json' }
** It turns out that the problem was at the server **
I'm trying to excute HTTP post request (from my angular client) to my server (node express). The server recive the request but the data is undefined.
Already tried to make this req by postman and it worked perfect there.
var req = {
method: 'POST',
url: _url +'/login',
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
},
data: { user: 'someUser', password :'somePass' }
}
$http(req)
.then(function success(res){
...
}, function error(res){
...
});
You are sending JSON data and sending the header of x-www-form-urlencoded.
Change the content type to "application/json"
Like:
headers: {
'Content-Type': 'application/json'
}
i am trying to send a POST request from my angularjs controller to the nodejs server which should then send a full POST request to the external API and this way avoid CORS request as well as make it more secure as i'm sending relatively private data in this POST request.
My angularjs controller function for making the post request to the nodejs server looks like this and it works fine:
var noteData = {
"id":accountNumber,
"notes":[
{
"lId":707414,
"oId":1369944,
"nId":4154191,
"price":23.84
}
]
}
var req = {
method: 'POST',
url: '/note',
data: noteData
}
$http(req).then(function(data){
console.log(data);
});
Now the problem lies in my nodejs server where i just can't seem to figure out how to properly send a POST request with custom headers and pass a JSON data variable..
i've trierd using the nodejs https function since the url i need to access is an https one and not http ,i've also tried the request function with no luck.
I know that the url and data i'm sending is correct since when i plug them into Postman it returns what i expect it to return.
Here are my different attempts on nodejs server:
The data from angularjs request is parsed and retrieved correctly using body-parser
Attempt Using Request:
app.post('/buyNote', function (req, res) {
var options = {
url: 'https://api.lendingclub.com/api/investor/v1/accounts/' + accountNumber + '/trades/buy/',
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': apiKey
},
data = JSON.stringify(req.body);
};
request(options, function (error, response, body) {
if (!error) {
// Print out the response body
// console.log(body)
console.log(response.statusCode);
res.sendStatus(200);
} else {
console.log(error);
}
})
This returns status code 500 for some reason, it's sending the data wrongly and hence why the server error...
Using https
var options = {
url: 'https://api.lendingclub.com/api/investor/v1/accounts/' + accountNumber + '/trades/buy/',
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': apiKey
}
};
var data = JSON.stringify(req.body);
var req = https.request(options, (res) => {
console.log(`STATUS: ${res.statusCode}`);
console.log(`HEADERS: ${JSON.stringify(res.headers)}`);
res.setEncoding('utf8');
res.on('data', (chunk) => {
console.log(`BODY: ${chunk}`);
});
res.on('end', () => {
console.log('No more data in response.');
});
});
req.on('error', (e) => {
console.log(`problem with request: ${e.message}`);
});
req.write(data);
req.end();
Https attempt return a 301 status for some reasons...
Using the same data, headers and the url in Postman returns a successful response 200 with the data i need...
I don't understand how i can make a simple http request...
Please note: this is my first project working with nodejs and angular, i would know how to implement something like this in php or java easily, but this is boggling me..
So after a lot of messing around and trying different things i have finally found the solution that performs well and does exactly what i need without over complicating things:
Using the module called request-promise is what did the trick. Here's the code that i used for it:
const request = require('request-promise');
const options = {
method: 'POST',
uri: 'https://requestedAPIsource.com/api',
body: req.body,
json: true,
headers: {
'Content-Type': 'application/json',
'Authorization': 'bwejjr33333333333'
}
}
request(options).then(function (response){
res.status(200).json(response);
})
.catch(function (err) {
console.log(err);
})
In my AngularJS app I am sending HTTP GET request as below.
MyService.HttpReq("testUrl", "GET", null);
HttpReq Method is defined in a service and implemented as below:
this.HttpReq = function(URL, method, payload)
{
$http({
url: URL,
method: method,
cache: false,
data: postData,
headers: {
'Content-Type': 'application/json',
}
}).success(function(response)
{
console.log("Success: "+JSON.stringify(response));
}).error(function(data, status)
{
console.error("Error");
});
}
First of all is this the right way of sending HTTP request in AngularJS?
The problem that I am facing is, some times I get cached data as response and HTTP request is not hitting the server. what can be the issue?
UPDATE
As per the comment and answer I have updated my HTTP request code as below, but still getting same issue.
this.HttpReq = function(URL, method, payload)
{
$http({
url: URL,
method: method,
cache: false,
data: payload,
headers: {
'Content-Type': 'application/json',
'Cache-Control' : 'no-cache'
}
}).
then(
function(response)
{
var data = response.data;
console.log("Success: "+JSON.stringify(data));
},
function(response)
{
var data = response.data || "Request failed";
var status = response.status;
console.error("Error: "+JSON.stringify(data));
}
);
}
IE Browsers will catch ajax get requests even if we add cache control headers to the response. Only way i found to solve the issue is to add some random parameter to the request. Please make sure the api have no problem even if you send extra parameters
MyService.HttpReq("testUrl?ts=" + Date.now(), "GET", null);
Just add cache: false attribute to config object.
https://docs.angularjs.org/api/ng/service/$http#caching
Also you can add header: 'Cache-Control' : 'no-cache'
