I'm trying to access this cookies (the response ones):
When I open the request in the chrome debug tools in the network section I can clearly see that the cookies are present, but how can I access those values from my code? I've never worked with cookies before and I don't know what to do to "extract" them... I'm working on a Ionic2 project using Http.
I've read that the allowCredentials: true header has to be sent but that didn't work...
Here's the request/response details:
Here's the service:
public callLogin(service_guid: string, pos_guid: string, login_data: Object) {
return this.http.post(
this.url + service_guid + "/" + pos_guid + "/ack",
login_data,
{withCredentials: true}
)
.map(response => response.headers);
}
And the caller:
this.__posService.callLogin(login_data.service_guid, login_data.pos_guid, {"password": data.password})
.subscribe(
res => {
console.log("Success:");
console.log(res.get("apsession"); // this returns undefined
},
err => {
console.log("Error:");
}
);
When I try to access the cookie from the header it returns undefined. What am I doing wrong here?
The name of the response header you are trying to get is actually Set-Cookie not apsession. So if you did something like res.get("set-cookie") it would return the first header that matched that name. Since you have more than 1, you could do:
let headers: Headers = res.headers;
headers.getAll('set-cookie');
which returns a list of all headers with that name. You could find apsession in there probably.
See:
https://angular.io/docs/ts/latest/api/http/index/Headers-class.html
https://developer.mozilla.org/en-US/docs/Web/API/Response/headers
https://developer.mozilla.org/en-US/docs/Web/API/Headers

As per the changelists, it's now possible to modify requests in middleware via:
const headers = new Headers(request.headers);
// Add a new request header
headers.set('x-hello-from-middleware', 'foo');
// Delete a request header from the client
headers.delete('x-from-client');
const resp = NextResponse.next({
// New option `request.headers` which accepts a Headers object
// overrides request headers with the specified new ones.
request: {
headers
}
});
This works fine.
It's also possible to add to to the response, such as adding cookies, via:
let response = NextResponse.next();
response.cookies.set({
name: 'access_token',
value: newAccessToken,
expires: expiresString,
path: '/',
});
return response
This also works fine.
Question
I'm having trouble understanding the technique to combine both.
If I modify the request, for returning. Ideally, I would create the headers object, as in the first example, and then add it to the response object in the second example, before returning response. Seems straightforward. Response is an object.
But I specify:
response.request = headers
or
attempt to make an object or response parameters and and add them alongside header parameters like:
const resp = NextResponse.next({
response: responseParams
request: {
headers
}
});
Neither work. I'm missing something obvious I can't find in the documentation. Any idea?
I didn't find a way to directly set response.request headers after declaring response (perhaps it's not possible) but I did overlook I could change the order I was doing things in and missed the obvious that I could also declare a new NextResponse with request variables as its own variable to add cookies to.
e.g.
let response = NextResponse.next({
request: {
headers: requestHeaders,
}
});
response.cookies.set({
name: 'access_token',
value: newAccessToken,
expires: expiresString,
path: '/',
});
return response
This solved the problem.
I work with vue and go for frontend and backend respectively. I send post request to my server and get 403 error code message(notAllowed). But in postman I get the objects and is fine.
Vue and Vuex
My axios post request:
const response = await this.$axios.post(`http://localhost:8000/v1/org/${params.organization}/kkms/${params.kkm}/closeShift`,{
headers : {
'token' : this.state.token.value
}});
I know I should also use other properties like 'Content-Type' and etc in headers, but know it works well with only "token" property in the other requests. I want to know whether problem in backend or frontend?
It seems you have a mistake in the axios request.
You are receiving a 403, that means you are not authorized (or sometimes something else, check the comments in the question and down here ).
As can be found in axios docs, the post request looks like this:
axios.post(url[, data[, config]]).
It accepts the config (so the headers) as THIRD parameter, while you are setting it as second parameter. Add an empty FormData object as second param, and just shift your config to the third param.
const fakeData = new FormData();
const response = await this.$axios.post(`http://localhost:8000/v1/org/${params.organization}/kkms/${params.kkm}/closeShift`,
fakeData,
{
headers : {
'token' : this.state.token.value
}
});
I am trying to fetch local api made in asp.net api which is running in https://localhost:44388/. When I tried to fetch get request it responds ok but return html not json. The problem might occur by two reasons:
1.typo in url (But I checked in my browser, it worked)
2.Server restart needed
What might be the problem with my code?
componentDidMount(){
var proxyUrl = "http://127.0.0.1:3000/";
var targetUrl = "https://127.0.0.1:44388/api/product/getproducts";
fetch(proxyUrl+targetUrl, {
method:'GET',
headers:{
'Access-Control-Allow-Origin':'*',
'Access-Control-Allow-Mehods': '*',
'Access-Control-Allow-Headers': '*',
'Access-Control-Allow-Credentials':'*',
'Content-type':'application/json'
}
})
.then(data=>{
if(!data.ok){
throw new Error("Error");
}else{
return data.json();
}
})
.then(data=>this.setState({products:data}))
}
when you give parameter as:proxyUrl+targetUrl,
actually the url which you have called is :
http://127.0.0.1:3000/https://127.0.0.1:44388/api/product/getproducts
which does not seems to be correct.
i think the structure of url you'v given to fetch function is wrong.
While doing the POST request in Angular 2, I am getting:
"EXCEPTION: Response with status: 404 Not Found for URL:" .
However, while accessing the URL directly, I am getting the response page.
Also in my backend code, I can see my data getting passed from client side to server side:
Response_body: "{"Message":"Not able to add Language = A"}"
headers: Headersok: false
status: 404
statusText: "Not Found"
type: 2
url: "http://localhost:1109/api/Language/AddLanguage"
onSubmit(val){
console.log(val);
this.languageService.testPost(val)
.subscribe(
(res:response) => console.log(res);
);
}
testPost(newVal) : Observable<any>{
let body = JSON.stringify(newVal);
console.log(body);
let headers = new Headers({'Content-Type' : 'application/json'});
let options = new RequestOptions({headers : headers});
return this.http.post(this.logUrl,body,options)
.map((res : Response) => res.json());
}
Yes Rachit,I think you are correct.While Debugging,In my Server side Code I found an Exception mentioning Too many Arguments while saving Data To Database.
There's the culprit I believe, this error generally occurs if you supply more than required params to an SP. So in your DB implementation if you are using SP(s) kindly check them one by one which one is supplying extra parameters. And if nothing else is the problem you should have this issue resolved.
I have a form in googlescript where I can add a user to a sheet.
Is there a way to implement some lines in that code so the script adds a post on a wordpress page?
I read that it's possible via wp_insert_post , but I have no idea how that works in my case.
EDIT:
As Spencer suggested I tried to do it via WP REST API.
The following code seems to be working .............
function httpPostTemplate() {
// URL for target web API
var url = 'http://example.de/wp-json/wp/v2/posts';
// For POST method, API parameters will be sent in the
// HTTP message payload.
// Start with an object containing name / value tuples.
var apiParams = {
// Relevant parameters would go here
'param1' : 'value1',
'param2' : 'value2' // etc.
};
// All 'application/json' content goes as a JSON string.
var payload = JSON.stringify(apiParams);
// Construct `fetch` params object
var params = {
'method': 'POST',
'contentType': 'application/json',
'payload': payload,
'muteHttpExceptions' : true
};
var response = UrlFetchApp.fetch(url, params)
// Check return code embedded in response.
var rc = response.getResponseCode();
var responseText = response.getContentText();
if (rc !== 200) {
// Log HTTP Error
Logger.log("Response (%s) %s",
rc,
responseText );
// Could throw an exception yourself, if appropriate
}
else {
// Successful POST, handle response normally
Logger.log( responseText );
}
}
But I get the error:
[16-09-28 21:24:29:475 CEST] Response (401.0)
{"code":"rest_cannot_create","message":"Sorry, you are not allowed to
create new posts.","data":{"status":401}}
Means: I have to authenticate first.
I installed the plugin: WP REST API - OAuth 1.0a Server
I setup a new user and got a client key and client user.
But from here I have no clue what to do : /
It is possible. Wordpress has a REST API. I can be found at:
http://v2.wp-api.org/
You will use the UrlFetchApp Service to access this api. Documentation can be found at:
https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app
Read the docs and try to write some code. It you get stuck post the code that is confusing you here and I'll update this answer.
You should add you authentification in the header :
var headers = {
... ,
'Authorization' : 'Basic ' + Utilities.base64Encode('USERNAME:PASSWORD'),
};
And then add your header in your parameters :
var params = {
'method': 'POST',
'headers': headers,
'payload': JSON.stringify(payload),
'muteHttpExceptions': true
}
And then use UrlfetchApp.fetch
var response = UrlFetchApp.fetch("https://.../wp-json/wp/v2/posts/", params)
Logger.log(response);
You need to pass the basic auth, like this:
// Construct `fetch` params object
var params = {
'method': 'POST',
'contentType': 'application/json',
'payload': payload,
'muteHttpExceptions' : true,
"headers" : {
"Authorization" : "Basic " + Utilities.base64Encode(username + ":" + password)+"",
"cache-control": "no-cache"
}
};
thank you for giving me these important links.

I installed WP REST API and the OAuth plugin.
In the documentation is written:
Once you have WP API and the OAuth server plugins activated on your
server, you’ll need to create a “client”. This is an identifier for
the application, and includes a “key” and “secret”, both needed to
link to your site.
I couldn't find out how to setup a client?
In my GoogleScriptCode according to the WP API I get the error:
{"code":"rest_cannot_create","message":"Sorry, you are not allowed to create new posts.","data":{"status":401}}
Edit: I found it - it's under User/Application
I'll try to figure it out and get back to you later.
