Observable with POST call in Angular2 - angular2-forms

I am using Angular2 in my application, And I saw advantages of using Observable while calling http calls. But somehow I am not able to make call when I am using Observable for POST requests, But it's working while GET request. If I use subscribe method, then POST is working.
Below is my code,
using Observable,
AddBreakoutsManually(breakoutUploads: Uploads): Observable<boolean> {
console.log("Data = ", JSON.stringify(breakoutUploads));
let headers = new Headers({ 'Content-Type': 'application/json' });
let options = new RequestOptions({ headers: headers });
return this.http.post("/breakout/InsertUploads", JSON.stringify(breakoutUploads), options)
.map((res: Response) => res.json())
.catch((error: any) => Observable.throw(error.json().error || 'Server error'));
}
Using subscribe,
Adding(breakoutUploads: Uploads) {
let headers = new Headers({ 'Content-Type': 'application/json' });
let options = new RequestOptions({ headers: headers });
this.http
.post('/breakout/InsertUploads', JSON.stringify(breakoutUploads), options)
.subscribe(data => {
alert('ok');
}, error => {
console.log(error.json());
});
}
My API,
[HttpPost]
public bool InsertUploads([FromBody]BreakoutUpload breakoutUploads)
{
return true;
}
What mistake I am making while using observable in POST call ?

Not sure what I changed, But it starts working with below code,
AddBreakoutsManually(breakoutUploads: Uploads): Observable<string> {
let headers = new Headers({ 'Content-Type': 'application/json' });
let options = new RequestOptions({ headers: headers });
return this.http.post(Configuration.Url_AddBreakoutsManually, JSON.stringify(breakoutUploads), options) // ...using post request
.map((res: Response) => res.json())
.catch((error: any) => Observable.throw(error.json().error || 'Server error'));
}

NativeScript-Angular - POST formdata to Wordpress ContactForm7 API

Hello everyone and thanks in advance ...
I'm trying to use the Contact Form7 APIs to fill in and submit a form from an Angular NativeScript App.
I have tried different solutions but I always get the same error response.
{"into":"#","status":"validation_failed","message":"Oops, there seems to be some error in the fields. Check and try again, please.","invalidFields":[{"into":"span.wpcf7-form-control-wrap.nome","message":"Attention, this field is required!","idref":null},{"into":"span.wpcf7-form-control-wrap.mail","message":"Attention, this field is required!","idref":null}]}
In the example I have entered static values ​​in the body for convenience
Help me ;(
attempt 1
onTappedInvia(): void {
fetch("http://www.example.com/wp-json/contact-form-7/v1/contact-forms/{id}/feedback", {
method: "POST",
headers: { "Content-Type": "multipart/form-data" },
body: JSON.stringify({
nome: "Test API",
mail: "test#test.test"
})
}).then((r) => r.json())
.then((response) => {
const result = response.json;
console.log(response);
}).catch((e) => {
console.log(e);
});
}
attempt 2
deliverForm() {
var formData: any = new FormData();
formData.append('nome', "Test API");
formData.append('email', "test#test.test");
formData.append('your-message', "Test API");
this.submitted=true;
console.log(formData);
this.formService.create(formData)
.subscribe(
data => {
console.log('Invoice successfully uploaded');
console.log('Error'+ JSON.stringify(data));
},
error => {
console.log('Error'+ JSON.stringify(error));
});
console.log('USCITO');
}
and formService
const HttpUploadOptions = {
headers: new HttpHeaders({ "Content-Type": "multipart/form-data;" })
}
#Injectable({
providedIn: 'root'
})
export class FormService {
constructor(
private HttpClient: HttpClient
) { }
create(formData){
return this.HttpClient.post('http://www.example.com/wp-json/contact-form-7/v1/contact-forms/{id}/feedback', formData, HttpUploadOptions)
}
}
The problem was with the Content-Type. i tried with application/x-www-form-urlencoded and it works!
fetch("http:www.aficfestival.it/wp-json/contact-form-7/v1/contact-forms/5173/feedback?", {
method: "POST",
headers: { "Content-Type": "application/x-www-form-urlencoded" },
body: form
}).then((r) => r.json())
.then((response) => {
const result = response.json;
console.log(response);
}).catch((e) => {
console.log(e);
});
}

Why is response undefined in Fetch request using Redux Store

I am writing a Fetch request to post new users to an application. The fetch is integrated with a redux store. Response returns [object Object] and response.status returns undefined. I am new to Redux and am wondering if that is where the error is. Here is the code from my actions creator file:
export function createCustomerSuccess(values) {
return {
type: types.CREATE_CUSTOMER_SUCCESS,
values: values
};
}
export function createCustomer(values) {
return function (dispatch, getState) {
console.log('values passing to store', values);
return postIndividual(values).then( (response) => {
console.log('calling customer actions');
console.log(response);
if(response.status === 200){
console.log(response.status);
dispatch(createCustomerSuccess(values));
console.log('create customer success');
}
else {
console.log('not successful');
}
});
};
}
function postIndividual(values) {
console.log('test from post' + JSON.stringify(values));
const URLPOST = "http://myurlisworking/Add";
return fetch (URLPOST, {
method: "POST",
headers: {
"Accept": "application/json",
"Content-Type": "application/json",
"Access-Control-Origin": "*"
},
body: JSON.stringify(values)
})
.then(response => response.json())
.then(response => {
console.log('response' + response.status)
});
}
Issue seems like with your fetch expectations. When your first .then gets called after fetch() then you get response.status available there to check.
You can rewrite your fetch like below and see if that resolves.
function postIndividual(values) {
console.log('test from post' + JSON.stringify(values));
const URLPOST = "http://myurlisworking/Add";
return fetch (URLPOST, {
method: "POST",
headers: {
"Accept": "application/json",
"Content-Type": "application/json",
"Access-Control-Origin": "*"
},
body: JSON.stringify(values)
})
.then(response => {
console.log('response' + response.status)
return response.ok && response.json();
})
.catch(err => console.log('Error:', err));
}
You can check response.status here ^ and do what you want.
Alternatively you can just do the fetch in postIndividual and handle response in your createCustomer instead.

HTTP request cannot get the contact photo using Microsoft Graph API

If I use the library #microsoft/microsoft-graph-client, I can get the contact photo as binary data, convert it to base64 and get the correct photo with the code below:
const request = require('request')
const microsoftGraph = require('#microsoft/microsoft-graph-client');
let token = token-value
let client = getMicrosoftGrapClient(token);
let id = contact-id;
let url = '/me/contacts/' + id + '/photo/$value';
client.api(url).get().then((res) => {
//console.log(res);
var encodedImage = new Buffer(res, 'binary').toString('base64');
console.log("encodedImage>>>>>>>>>>>>>>>>>>>>>>")
console.log (encodedImage);
}).catch((err) => {
console.log(err);
});;
function getMicrosoftGrapClient (token) {
// Create a Graph client
return microsoftGraph.Client.init({
authProvider: (done) => {
// Just return the token
done(null, token);
}});
}
I cannot get the correct contact photo with the HTTP GET. The HTTP
response code is 200 but the body is not the binary data of photo.
Please let me know what the error is. Here is the code:
const request = require('request')
request({
url: "https://graph.microsoft.com/v1.0/me/contacts/{contact_id}/photo/$value",
method: 'GET',
headers: {
'content-type': 'image/jpg',
'Authorization': 'Bearer {token}'
}
}, function (error, response, body){
console.log(error);
var encodedImage = new Buffer(body, 'binary').toString('base64');
console.log(encodedImage);
});
Encoding needs to be explicitly specified as
encoding: null
In that case the body will be of type Buffer, instead of the default (string).
And content-type could be omitted.
Example
request({
url: "https://graph.microsoft.com/v1.0/me/photo/$value",
method: 'GET',
encoding: null,
headers: {
'Authorization': 'Bearer ' + accessToken,
}
}, function (error, response, body) {
var encImage = new Buffer(body, 'binary');
fs.writeFileSync(filePath, encImage );
});

With a `new Request` in Node/React, how to pass params with a GET request?

I have the following API call in my Reactjs app:
static getAllSkills(title_id) {
const request = new Request(`http://localhost:4300/api/v1/job_title_skills`, {
method: 'GET',
headers: new Headers({
'Content-Type': 'application/json'
}),
body: JSON.stringify({title_id: title_id})
});
return fetch(request).then(response => {
return response.json();
}).catch(error => {
return error;
});
}
Which points to a Rails endpoint which expects the param title_id like so:
def index
#skills = Skill.where(id: params[:title_id])
....
end
The controller is expecting a GET request however with the above, I'm getting the following JS console error:
Uncaught TypeError: Failed to construct 'Request': Request with GET/HEAD method cannot have body.
What is the right way to construct the Request and pass the param to the API?
I think the url in your api is waiting for the title_id maybe like:
api/v1/job_title_skills/:title_id
So you can append it in your url when you make the request:
static getAllSkills(title_id) {
const request = new Request(`http://localhost:4300/api/v1/job_title_skills/${title_id}`, {
headers: new Headers({
'Content-Type': 'application/json'
})
});
return fetch(request).then(response => {
return response.json();
}).catch(error => {
return error;
});
}

How to add a BearerToken to React API Requests?

newbie to React looking for some help... I'm using React to make API requests like so:
class CatsApi {
static createCat(cat) {
const request = new Request('http://localhost:4300/api/v1/cats', {
method: 'POST',
headers: new Headers({
'Content-Type': 'application/json'
}),
body: JSON.stringify(cat)
});
return fetch(request).then(response => {
return response.json();
}).catch(error => {
return error;
});
}
Meanwhile, I have authentication to my API via react-devise:
https://github.com/timscott/react-devise
Which has a method getBearerToken like so: https://github.com/timscott/react-devise/blob/master/src/actions/authTokenStore.js
How do I use getBearerToken to pass the API the token so API requests are authenticated with the token?
Thank you!
You can use the Authorization header like:
{ 'Authorization': `Bearer ${authToken}` }
Using fetch you could try with something like:
fetch('http://localhost:4300/api/v1/cats', {
method: 'POST',
headers: {
'Authorization': `Bearer ${token}`
'Accept' : 'application/json',
'Content-Type' : 'application/json',
},
body: JSON.stringify({
cat : cat_value,
})
})
.then((response) => response.json())
.then((responseData) => { console.log(responseData) })
.catch((error) => { console.log(error) })
.done()
Also, it'd be great to see what's the Rails output in the console when you make a request, or the browser console.
