I have created a doGet and doPost endpoints in my appscript. When I hit the endpoint to make a post request from Python, it does work perfectly and as expected.
But when I try to hit the same url with my Flutter based mobile App, it throws me an XML error. (Which I suspect is related to CORSING).
When I hit the url with get request, I get the right response, but post request is failing. To ensure that my Post request is properly configured, I have made a post request to public API and it worked like charm.
Is it possible to add headers, where I could enable cors like this:
allowHeaders = {
"Access-Control-Allow-Origin": "*", // Required for CORS support to work
"Access-Control-Allow-Credentials": true, // Required for cookies, authorization headers with HTTPS
"Access-Control-Allow-Headers": "Origin,Content-Type,X-Amz-Date,Authorization,X-Api-Key,X-Amz-Security-Token,locale",
"Access-Control-Allow-Methods": "POST, OPTIONS"
}
Here is what my doPost request returns:
ContentService.createTextOutput(JSON.stringify(
{
data: isAuthenticated.data,
error: true,
//request: request,
msg: query.apiKey,
//paramters:request.parameters
})).setMimeType(ContentService.MimeType.JSON)
Here is my python script to get the post response:
requests.post("https://script.google.com/macros/s/AKfycbz7kTROol8u509M_p9pMZ9XRnL-myVjcRQKeb9Etp_OIMPnH640vHf_0Jp2dvvrbto7kOg/exec",
json = requestObject)
And here is my Flutter function:
Future<http.Response> createAlbum() async{
print("Trying to make a post request");
var result = await http.post(Uri.parse('https://script.google.com/macros/s/AKfycbz7kTROol8u509M_p9pMZ9XRnL-myVjcRQKeb9Etp_OIMPnH640vHf_0Jp2dvRIco7kOg/exec'),
headers: {"Content-Type": "application/json"},
body: jsonEncode(<String, dynamic>{
"apiKey":apiKey,
"operationType":"register_user",
"operationData": {
"email": "shivam#yoptima.com",
"otp": 318728
}
}),
);
print("Here is the result: " + result.body);
}
Just to clarify things:
Get Request works for both the platforms.
Post Request works with python for AppScript.
Post Request works for any other public API from flutter.
Post Request doesn't work for Flutter when Hitting AppScript API.
I suspect it to be something to do with CORS. (But not very sure).
Flutter http library makes request via XMLHttpRequest.

For GET and POST requests for a private server I work with I use in Google Sheets, do something like this, and I get a proper response. I use that response to update data and just as importantly for error checking by evaluating response.getResponeCode().
function postDataToServer(params){
let myjdService = getService();
let orgId = getOrgIdForSelectedOrg();
let link = https://GoodURLForPrivateDataIWorkWithALot/neededurlParameter/anotherNeededURLParameter;
let options = {
'method': 'put',
'payload': JSON.stringify(params),
'headers': {
'Accept': 'application/vnd.PRIVATE.v3+json',
'Content-Type': 'application/vnd.PRIVATE.v3+json',
'authorization': 'Bearer ' + myPrivateService.getAccessToken()
}
};
let response = UrlFetchApp.fetch(link, options);
return response.getResponseCode();
For all the GET and POST requests I do, I get a response. And from that response I can parse a response code. But for the specific server I work with, when I edit a record using PUT, a successful edit returns this:
204 No Content
And further, the last line return response.getResponseCode() returns an error the response is undefined.
Here's the error I get for doing anything with response:
ReferenceError: response is not defined
The PUT is working. I only know this because 1) when I check if edits are made with the server, they are 2) testing the PUT in Postman at least shows me the words "204 No Content" and 3) the documentation says that's exactly what I should expect.
But I still would like to find out how to evaluate this no-content response in my Google Sheets App for proper error tracking. At least some way to get the string "204". Any ideas? I can't even get Google Sheets to do say 204.
I am trying to make a GET request to an external API from a Google Apps Script using UrlFetchApp. When I make this request with Postman or curl, I get back the expected response. However, when I try it with UrlFetchApp, I get back an empty response, {}.
I have tried using Basic Auth and OAuth 2, as well as explicitly setting the oauthScopes property in the manifest as described here.
I have confirmed with the API team that they are indeed sending back a full response when I hit the endpoint, but all I receive is {}. My problem seems similar to this StackOverflow question which went unanswered.
var headers = {
"X-Client-Key": "KEY",
"Authorization": "Bearer TOKEN"
};
var options = {
method: "get",
headers: headers,
}
var response = UrlFetchApp.fetch(ENDPOINT, options);
console.log(JSON.stringify(response)); // returns {}
Do not take what you see in logs at face value. fetch method of the UrlFetchApp service always returns an instance of HTTPResponse which is an object first and foremost. This is what the logs show you (I am assuming you are logging the response because this is the only context I am aware of where {} is displayed).
To extract useful information from the response, use the appropriate methods exposed on HTTPResponse instances, like getResponseCode or getContentText.
When I make a request via apps script, the response is inconsistent than when I make a request with a tool like postman or any other way of sending a post request, it seems specific to apps script.
Here is my request:
var headers = {'Authorization': 'Bearer #'},
var payload = JSON.stringify({'_id':_id, "email": email}),
var options = {
'method': 'post',
'contentType': 'application/x-www-form-urlencoded',
'payload': payload,
'headers': headers,
'muteHttpExceptions':false
}
var response = UrlFetchApp.fetch('https://...", options);
The response code is 201, it appears that the contentText returned in the response is correct except for one key piece of information, the email that was sent in the post payload should be in the response as well. After the post is sent, it triggers an email using the email sent in the payload. This doesn't work with the apps script post request.
When I run this same exact request via postman or another tool, it works perfectly, the email is triggered right after the request is sent and works as intended.
Does anyone have any ideas why the "email" in the payload isn't working via apps script, but does via postman? Do I have an error in payload or way I'm using UrlFetchApp?
Change content type to:
'contentType': 'application/json',
The documentation shows an example with the object stringified, and they change the contentType
Apps Script Documentation UrlFetchApp.fetch(url, parameters)
I wrote a pretty basic API using a SilverStripe module (here) and while building it I was testing using Postman and Advanced REST Client chrome extension so I know the endpoints work.
Now when trying to reach the endpoints (POST json) the API is telling me that required values aren't set. I'm did a little bit of digging and compared the request headers from Postman to the ones from Angular using Firebug. The only noticeable discrepancy is that in Postman the header for Content-Type is:
"application/json"
and for Angular it's:
"application/json; charset=UTF-8"
Here's the code for the Angular POST (pretty basic):
notebookFactory.addNotebook = function(title) {
var notebook = "Testing Title 23!";
var message = {
Title: notebook
};
return $http({
url: 'api/notebook',
method: 'POST',
headers: { 'Content-Type': 'application/json' },
data: message
});
};
The API error says: "The JSON property Title is required"
Is this something that could make a difference? I've tried adding charset=UTF-8 to the end of the Content-Type in Postman and receive the same error. Is there any way to remove the charset from the Angular POST header?
Let me know if you need any more info and thanks in advance!
This was a small issue with the code for handling json in the RESTful API module.
The developer has made the fix already and can be referenced here: https://github.com/pstaender/silverstripe-restful-api/issues/1
I'm trying to use the V2.2 of StackExchange API in Google Apps Script.
The problem comes in the last step of the explicit OAuth 2.0 flow, when I try to send the POST request to obtain the access token. I receive a 404 error, but making the same request manually (using postman extension) everything is ok.
To simplify the problem, if I send this POST request with no payload I receive the same 404
var response = UrlFetchApp.fetch("https://stackexchange.com/oauth/access_token", {
method: 'post',
muteHttpExceptions: true
});
Logger.log(response);
while in postman I receive this 400:
{
"error": {
"type": "invalid_request",
"message": "client_id not provided"
}
}
I guess this will be a problem with UrlFetchApp, but does anyone know how to solve it? Thanks!
The problem is related with the Origin header.
You cannot remove from the header directly but you can perform the call via a proxy :)
You need to provide the data for the post by adding an 'option' object to the call.
For example:
var options = { "method" : "post", "payload" : payload };
UrlFetchApp.fetch("https://stackexchange.com/oauth/access_token", options);
Btw, have you tried you use the OAuth that UrlFetch got: https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app#addOAuthService(String) - It might be better way.
