Postman pre-request to get token doesn't work

At this time I can perform succesfully my Postman request to get my token. I'm using these parameters :
-Basic Authorization in the headers
-and this body
-
Now I would like to get this request as a pre-request script (and use an environment variable for the token).
Here is the script :
pm.sendRequest({
url: 'http://localhost:8084/oauth/token',
method: 'POST',
header: {
'Authorization':'Basic Y2xpZW50OnBhc3N3b3Jk',
'content-type': 'application/x-www-form-urlencoded'
},
data:{
'password':'secret',
'username':'admin',
'grant_type':'password'
}
}, (err, res) => pm.environment.set("token", res.json().access_token));
It doesn't work with the response : Full authentication is required to access this resource.
What is wrong?
Thanks

You could change the data section to something like this?
body:{
mode:"urlencoded",
urlencoded:[
{
key:"grant_type",
value:"password"
},
{
key:"username",
value:"admin"
},
{
key:"password",
value:"secret"
}
]
}
A great resource for pm.sendRequest() examples can be found here

http basic authorization with Flask REST

I am developing a simple REST service in flask.
I have been trying to implement basic authorization.
Whilst, I can pass the username and password from the webpage using manual entry, I can't seem to read them from the header.
Here is my code:
On the server
def test():
if request.authorization and request.authorization.username == '***' and request.authorization.password == '***':
return "Authorized"
else:
return make_response('Authorization failed', 401, {'WWW-Authenticate': 'Basic realm ="Login Required"'})
On the client - using JavaScript
<script>
$(document).ready(function(){
$("#authButton").click(function(){
$.ajax({
xhrFields: {
withCredentials: true
},
headers: {
'Authorization': "Basic " + btoa("***:***")
},
url: "********:5001/",
type: 'GET',
success: function(){
console.log("success");
},
error: function (){
console.log("error");
},
});
});
});
</script
>
I have also tried the Javascript code without the xhr fields section, but for neither do I get anything returned at all.
If I don't send the headers from the client it works and simply asks for manual input of the username and password.
All I'm trying to do is authenticate from the header.
Any pointers would be very gratefully received.

Create a gist using GitHub API

I wanna create a gist using GitHub API. I tried an POST ajax request:
var gist = {
"description": "Avatars",
"public": true,
"files": {
"check.txt": {
"content": "Avatars list..."
}
}
};
$.ajax({
url: 'https://api.github.com/gists',
type: 'POST',
dataType: 'json',
data: JSON.stringify(gist),
success: function(e) {
console.log(e);
},
error: function(e) {
console.error("Error!: ", e);
}
});
But I always get the following error:
jquery-3.1.1.min.js:4 POST https://api.github.com/gists 401 (Unauthorized)
Can anyone help me?
Thanks

When you want to edit things on Github, you need to authorize your request. Either by adding a username and password to the request or an oauth token.
More information can be found in the authorization documentation: https://developer.github.com/v3/auth/

Since I ran across the same problem recently, let me add the examples requested by T.Todua
If you want to authenticate with username and password, add the following lines to your $.ajax request:
crossDomain: true,
beforeSend: function (XHR) {
XHR.setRequestHeader(
'Authorization','Basic ' + btoa(Username + ':' + Password)
);
},
If, however, you created an access token for your gists (see Github help and don't forget to check the "Gist" permission!) then add the following lines instead
crossDomain: true,
headers: {
'Authorization':'bearer ' + GitHubAccessToken
},
The GitHubAccessToken will be shown once (and only once!) immediately after creation, so make sure to store it in a safe location as everybody knowing this access token will be able to modify your gists (until you revoke it again).

Errors while trying to "Put" JSON Data

I am working with the Hubspot API and I am trying to modify the close date of a deal via the "PUT" Method by sending JSON Data. But I am getting errors such as
{ status: 'error', message: 'Invalid input JSON on line 1, column
15: Can not deserialize instance of java.util.ArrayList out of
START_OBJECT token', correlationId:
'b8b47229-184d-40b3-b402-9e3dd684b217', requestId:
'd364fe8dac5e876639928dd0d04045fd' }
This is the code that I have written-
fetch('https://api.hubapi.com/deals/v1/deal/103361780?hapikey=', {
method: 'put',
headers: {
'Accept': 'application/json, text/plain, */*',
'Content-Type': 'application/json'
},
body: JSON.stringify({"properties":{name: "closedate", "value": 1528744207881}})
}).then(res=>res.json())
.then(res => console.log(res));
This is the JSON Data that I am trying to pass
{
"properties":[
{
"name": "closedate",
"value": 1528744207881
}
]
};
And here is the documentation of making a PUT request via the Hubspot API.
I am able to successfully update the value via POSTMAN.
Any help on this matter would be greatly appreciated.

You are missing brackets - [] and on the backend, they are waiting for an array to deserialize it to Arraylist.
Try fetch with this body:
{"properties":[{"name": "closedate", "value": 1528744207881}]}

Yammer Open Graph Post - How do i do it?

I am trying to figure out how the payload should be constructed for a Open Graph object to submit to yammer. I can post a standard message, but i would like to post an opengraph message instead.
{
"activity":{
"actor":{"name":"Sidd Singh",
"email":"sidd#xyz.com"},
"action":"create",
"object": {
"url":"https://www.sched.do",
"title":"Lunch Meeting"
},
"message":"Hey, let’s get sushi!",
"users":[
{"name":"Adarsh Pandit",
"email":"adarsh#xyz.com"}
]
}
}
This is some code nicked from their API documentation but doesn't show me how i should use this in javascript. Can someone assist me? Below is my existing code that posts a standard message...
yam.request({
url: "https://www.yammer.com/api/v1/messages.json?network_id=networkname", //this is one of many REST endpoints that are available
method: "POST",
beforeSend: function (req) { //send the access_token in the HTTP header
req.headers.Authorization = "Bearer " + access_token;
},
data: {
"network": "networkname",
"body": "Test Post",
"group_id": "3719771"
},
success: function (data) { //print message response information to the console
toastr.success('An Item was successfully posted to Yammer', "Yammer Network");
},
error: function (user) {
toastr.error('There was an error eith the request', "Yammer Network");
}
});

This post answered your question: Yammer Open Graph API Error 400
Simply replace the key value pairs in the data{} with the activity json strings. Also remember to change the RESTful api endpoint to https://api.yammer.com/api/v1/activity.json
