Hi I am trying to get the gender back from a curl request in node.js.
I am following these instructions https://developers.facebook.com/docs/messenger-platform/user-profile
my code is below, but i get an error during the execution.
I call the below using fbUserInfo(recipentId).catch(console.error);
const fbUserInfo = (id) => {
//const body = JSON.stringify({
// recipient: { id },
// message: { text },
//});
const qs = 'access_token=' + encodeURIComponent(FB_PAGE_TOKEN1);
return fetch('https://graph.facebook.com/v2.6/' + id + '?fields=first_name,last_name,profile_pic,locale,timezone,gender&' + qs, {
method: 'POST',
headers: {'Content-Type': 'application/json'},
//body,
})
.then(rsp => rsp.json())
.then(json => {
if (json.error && json.error.message) {
throw new Error(json.error.message);
}
return json;
});
console.log('=== ' + json); // I was hoping this would output the returned json
}; // const

I'm new in React Native. I would like to extract a value from json with fetch to do a simple test to begin. But I don't understand, how to select a particular key from Json. Always, I have undefined return. I tried to modify my code with this post but it doesn't work. I tried to parse before but he didn't want because it's already an object.
This is my code:
checkLogin = () => {
const { name } = this.state;
const { surname } = this.state;
fetch('https://ffn.extranat.fr/webffn/_recherche.php?go=ind&idrch=' + name + '%20' + surname, {
method: 'GET',
}).then((response) => response.json())
.then((responseJson) => {
if (responseJson.ind == 'Individu non trouv\u00e9 !') {
alert("Id incorrect")
}
else {
alert("Id correct");
}
alert(JSON.stringify(responseJson.ind))
}).catch((error) => {
console.error(error);
});
}
This is my JSON format:
[{"iuf":"1366701","ind":"LEBRUN L\u00e9o (2000) H FRA - CN BEAUPREAU","sex":"#1e90ff","clb":"CN BEAUPREAU"}]
I know my request work because when I run this code alert(JSON.stringify(responseJson)).It return the entire json. So I don't know, how to resolve the undefined return.

Your json is an array, you either need to loop through it if there is multiple items inside, or just use responseJson[0] to read it. So if you want to read your json, your code would look like this :
const checkLogin = () => {
const { name } = this.state;
const { surname } = this.state;
fetch(
"https://ffn.extranat.fr/webffn/_recherche.php?go=ind&idrch=" +
name +
"%20" +
surname,
{
method: "GET"
}
)
.then(response => response.json())
.then(responseJson => {
// Since you have only one object inside your json, you can read the first item with 'responseJson[0]'.
if (responseJson[0].ind == "Individu non trouv\u00e9 !") {
alert("Id incorrect");
} else {
alert("Id correct");
}
alert(JSON.stringify(responseJson[0].ind));
// If you have multiple elements inside your responseJson,
// then here is a loop example :
// responseJson.forEach(item => {
// console.log('item ind = ', item.ind);
// });
})
.catch(error => {
console.error(error);
});
};
Use async await.
const checkLogin = async () => {
const { name } = this.state;
const { surname } = this.state;
const request = await fetch(
"https://ffn.extranat.fr/webffn/_recherche.php?go=ind&idrch=" +
name +
"%20" +
surname)
const response = await request.json();
console.log('result from server', response)
}
i am developing an app with node express js and angular js. My angular app makes an api request from node js app server on each route or button click, also a single component or button click may request multiple api to node js app. upon requesting multiple time the data loading is just got stopped and i am not getting result. Also getting status code like 304 and 204.
please check out my api code and subscribe service code.

The express js is working well. It is fault in database connection limit.
the DB connection limit was set as 10. So,after 10 api request with sql query. The db connection gets disconnected.
I have migrated a piece of code to be able to export data as excel file in angular.
I assume the fact that the json is well formed and send from the server to the angular side. I can see it in the network frame in th browser.
For small json, it's ok but when the size of the json starts to be large, the answer still failed.
This following code corresponding to the service call
exportSynthesis(recordId: number, moduleId: number) {
const body = null;
return this.http.post(this.apiUrl + `/data`
+ `${recordId}/module/${moduleId}`, body,
{
headers: new HttpHeaders({ 'Content-Type': 'application/json' }),
observe: 'response', responseType: 'json' }).pipe(
map((resp: any) => {
return resp.body;
}));
}
and here, its the method which manages the return.
exportSynthesis() {
this.service.exportSynthesis(this.recordId, this.moduleId)
.subscribe(
(exportResult) => { this.exportResult = exportResult; },
err => {
console.log('err:', err);
this.errorHandlerService.handleError('failed', err);
},
() => {
console.log('json:', this.exportResult);
const worksheet: XLSX.WorkSheet = XLSX.utils.json_to_sheet(this.exportResult);
const workbook: XLSX.WorkBook = { Sheets: { 'data': worksheet }, SheetNames: ['data'] };
const excelBuffer: any = XLSX.write(workbook, { bookType: 'xlsx', type: 'array' });
const blob = new Blob([excelBuffer], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet;charset=UTF-8' });
const url = window.URL.createObjectURL(blob);
const a = document.createElement('a');
a.href = url;
a.download = '(GEO) ' + this.record.label + ' - name.xlsx';
a.click();
window.URL.revokeObjectURL(url);
a.remove();
});
}
Currently, i do not manage to understand why it still finish in error and I get only "ok" in the console log.
Any idea?

Angular's HttpClientModule default response is a json.
Your problem is that you try to access the body property of the HTTP response, but Angular interprets that as you trying to access the body property in the body of the response.
Remove observe and responseType from your post request and treat the response as a json. It should work.
find:
just need to use text as json
return this.http.post(this.apiUrl + `/geo/v1/synthesis/xls/record/`
+ `${recordId}/module/${moduleId}`, body,
{
headers: headers,
observe: 'response',
responseType: 'text' as 'json'}).
map((resp: any) => {
return resp.body;
});
}
we have storage array which supports REST API. I am able to do all ( GET/POST/DELETE/PUT) through postman and need to implement one of POST operation through Node.js script.
I am successful in node.js GET operation. But still not able to get the simple POST operation through multiple tries with various forms. here is the codes of both GET and PUT. Also the successful POST operation screenshot by the postman.
Appreciate any help.
GET: Node.js code ( working ):
var request = require('request');
function get_trustyou(trust_you_id, callback){
var options = {
url: 'https://xxxxxx/api/json/v2/types/consistency-groups',
rejectUnauthorized: false,
method: 'GET',
type: 'application/json',
auth:{
user: 'xxxxx',
pass: 'xxx'
}
};
var res = '';
request(options, function ( error, resp, body ) {
if ( !error && resp.statusCode == 200){
res = body;
}
if (error) {
console.log("this is error" + error);
}
callback(res);
});
}
get_trustyou("674fa44c-1fbd-4275-aa72-a20f262372cd", function(resp){
console.log("Here is the result" + resp);
});
POST: Node.js code ( Not working ):
var request = require('request');
function get_trustyou(trust_you_id, callback){
var options = {
body: postData,
url: 'https://xxxx/api/json/v2/types/consistency-groups',
rejectUnauthorized: false,
method: 'POST',
type: 'application/json',
auth:{
user: 'xxxx',
pass: 'xxxxx'
},
form: {
'consistency-group-name': 'TEST-CG'
}
};
request(options, function ( error, resp, body ) {
if ( !error && resp.statusCode == 200){
res = body;
}
if (error) {
console.log("this is error" + error);
}
callback(res);
});

I am trying to download an OBJ file generated from SVF file, using the Autodesk.Forge .NET API method GetDerivativeManifest (C#). The OBJ file has been created successfully. However, the method does not provide a Stream that I can use to retrieve the file and save it locally.
How can I get the OBJ file?
I don't have a C# sample ready to give you, but I hit the same issue with the Node.js SDK. I worked around by implementing the REST call myself:
download (token, urn, derivativeURN, opts = {}) {
// TODO SDK KO
//this._APIAuth.accessToken = token
//
//return this._derivativesAPI.getDerivativeManifest(
// urn,
// derivativeURN,
// opts)
return new Promise((resolve, reject) => {
const url =
`${DerivativeSvc.SERVICE_BASE_URL}/designdata/` +
`${encodeURIComponent(urn)}/manifest/` +
`${encodeURIComponent(derivativeURN)}`
request({
url: url,
method: 'GET',
headers: {
'Authorization': 'Bearer ' + token.access_token
},
encoding: null
}, function(err, response, body) {
try {
if (err) {
return reject(err)
}
if (response && [200, 201, 202].indexOf(
response.statusCode) < 0) {
return reject(response.statusMessage)
}
if (opts.base64) {
resolve(bufferToBase64(body))
} else {
resolve(body)
}
} catch(ex) {
console.log(ex)
reject(ex)
}
})
})
}
Here is how I invoke that method within my endpoint:
/////////////////////////////////////////////////////////
// GET /download
// Download derivative resource
//
/////////////////////////////////////////////////////////
router.get('/download', async (req, res) => {
try {
const filename = req.query.filename || 'download'
const derivativeUrn = req.query.derivativeUrn
// return base64 encoded for thumbnails
const base64 = req.query.base64
const urn = req.query.urn
const forgeSvc = ServiceManager.getService(
'ForgeSvc')
const token = await forgeSvc.get2LeggedToken()
const derivativesSvc = ServiceManager.getService(
'DerivativesSvc')
const response = await derivativesSvc.download(
token, urn, derivativeUrn, {
base64: base64
})
res.set('Content-Type', 'application/octet-stream')
res.set('Content-Disposition',
`attachment filename="${filename}"`)
res.end(response)
} catch (ex) {
res.status(ex.statusCode || 500)
res.json(ex)
}
})
Hope that helps
