here is the request:(i required node-fetch as fetch to do http requests on the server)
const { code } = req.body;
const data = new FormData();
data.append("client_id", process.env.GITHUB_CLIENT_ID);
data.append("client_secret", process.env.GITHUB_CLIENT_SECRET);
data.append("code", code);

headers: {
Accept: "application/json",
},
})
.then(res => res.json())
.then(res => {
console.log(res);
})
.catch(err => {
console.log(err)
})
here is the response:
{ error: 'Not Found' }
I am trying to recall the API request after getting the refresh token from the API.
Having issue in recall the same API request.
It shows invalid access token error while running this api.

How to fix this issue? Help me with the solution.
Remove last return response; and unnecessary Future.delayed. Something like this could work:
Future<http.Response> _getAPIById(String pathURL) async {
try {
http.Response response = await _ioClient.get(
Uri.http(ApiConstants.baseUrl, pathURL),
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer ' + accessToken!
},
);
if (response.statusCode == 401) {
await refreshAccessToken();
return await _ioClient.get(
uri,
headers: {
HttpHeaders.contentTypeHeader: 'application/json',
'x-access-token': 'Bearer ' + accessToken!
},
);
} else {
return response;
}
} catch (e) {
throw Exception('Error occurred');
}
}
I often use Axios to perform requests in my applications, however due to incompatibility with iphone, I had to use the capacitor-community/http library, however the try catch blocks are always returning success, even if there was an error in the request. How can I handle errors using this library?
try {
await Requester.auth.public.login(formData);
this.$store.dispatch('login', user);
this.$root.$emit('showToast', {
text: 'Seja bem vindo!',
color: 'success',
});
this.$router.push({ name: 'Cotacao' });
} catch (err) {
this.$root.$emit('showToast', {
text: err.response?.data ?? err.toString(),
color: 'error',
});
} finally {
this.loading.submitForm = false;
}
},
My request
const login = async (formData: AuthLoginFormData): Promise<User> => {
const res: HttpResponse = await Http.post({
url: `${BASE_URL}public/auth/login`,
headers: {
'Content-Type': 'application/json',
},
data: formData,
webFetchExtra: {
credentials: 'include',
},
});
return res.data;
};
Install Latest https://github.com/capacitor-community/http plugin
use function
public async login(formData: AuthLoginFormData){
let options = {
url: `${BASE_URL}public/auth/login`,
headers: {
'Content-Type': 'application/json',
},
data: formData,
webFetchExtra: {
credentials: 'include',
}
};
let response: HttpResponse = await Http.request(options);
if (response.status === 200) {
return Promise.resolve(res);
}
return Promise.reject(response.data);
}
I've tried using axios and fetch to get data from an API endpoint, but turns out to have only returned an empty array. It works fine in Postman. What have I missed?
Using Axios
axios({
method: "get",
url: "/api/purchase/receivegoods/index?action=detail-grn",
params: {
goods_receive_id: 71,
},
headers: {
"Content-Type": "application/json",
Accept: "application/json",
},
})
.then((response) => {
console.log(("response", response));
})
.catch((error) => {
console.log("error message: ", error.message);
});
Using Fetch
fetch(
"https://devactive.com/api/purchase/receivegoods/index?action=detail-grn",
{
method: "GET",
headers: {
Accept: "application/json",
"Content-Type": "application/json",
},
params: {
goods_receive_id: 71,
},
}
)
.then((response) => response.json())
.then((result) => {
console.log("Success:", result);
})
.catch((error) => {
console.error("Error:", error);
});
EDIT:
The request is in JSON format. It looks like this (this is an example of an existing id:
{
"goods_receive_id" : 71
}
check for possible proxy configuration, postman uses system proxy by default.
You are not passing the data as the body when using Axios or Fetch. You are hitting the endpoint though. Try something like this:
data = {
"goods_receive_id" : 71
}
axios({
method: "get",
url: "/api/purchase/receivegoods/index?action=detail-grn",
data: JSON.stringify(data), // <- You add the data to the body here
headers: {
"Content-Type": "application/json",
Accept: "application/json",
},
})
.then((response) => {
console.log(("response", response));
})
.catch((error) => {
console.log("error message: ", error.message);
});
or
data = {
"goods_receive_id" : 71
}
fetch(
"https://devactive.com/api/purchase/receivegoods/index?action=detail-grn",
{
method: "GET",
headers: {
Accept: "application/json",
"Content-Type": "application/json",
},
data: JSON.stringify(data), // <- You add the data to the body here
}
)
.then((response) => response.json())
.then((result) => {
console.log("Success:", result);
})
.catch((error) => {
console.error("Error:", error);
});
I have written an Axios POST request as recommended from the npm package documentation like:
var data = {
'key1': 'val1',
'key2': 'val2'
}
axios.post(Helper.getUserAPI(), data)
.then((response) => {
dispatch({type: FOUND_USER, data: response.data[0]})
})
.catch((error) => {
dispatch({type: ERROR_FINDING_USER})
})
And it works, but now I have modified my backend API to accept headers.
Content-Type: 'application/json'
Authorization: 'JWT fefege...'
Now, this request works fine on Postman, but when writing an axios call, I follow this link and can't quite get it to work.
I am constantly getting 400 BAD Request error.
Here is my modified request:
axios.post(Helper.getUserAPI(), {
headers: {
'Content-Type': 'application/json',
'Authorization': 'JWT fefege...'
},
data
})
.then((response) => {
dispatch({type: FOUND_USER, data: response.data[0]})
})
.catch((error) => {
dispatch({type: ERROR_FINDING_USER})
})
When using Axios, in order to pass custom headers, supply an object containing the headers as the last argument
Modify your Axios request like:
const headers = {
'Content-Type': 'application/json',
'Authorization': 'JWT fefege...'
}
axios.post(Helper.getUserAPI(), data, {
headers: headers
})
.then((response) => {
dispatch({
type: FOUND_USER,
data: response.data[0]
})
})
.catch((error) => {
dispatch({
type: ERROR_FINDING_USER
})
})
Here is a full example of an axios.post request with custom headers
var postData = {
email: "test#test.com",
password: "password"
};
let axiosConfig = {
headers: {
'Content-Type': 'application/json;charset=UTF-8',
"Access-Control-Allow-Origin": "*",
}
};
axios.post('http://<host>:<port>/<path>', postData, axiosConfig)
.then((res) => {
console.log("RESPONSE RECEIVED: ", res);
})
.catch((err) => {
console.log("AXIOS ERROR: ", err);
})
To set headers in an Axios POST request, pass the third object to the axios.post() call.
const token = '..your token..'
axios.post(url, {
//...data
}, {
headers: {
'Authorization': `Basic ${token}`
}
})
To set headers in an Axios GET request, pass a second object to the axios.get() call.
const token = '..your token..'
axios.get(url, {
headers: {
'Authorization': `Basic ${token}`
}
})
const data = {
email: "me#me.com",
username: "me"
};
const options = {
headers: {
'Content-Type': 'application/json',
}
};
axios.post('http://path', data, options)
.then((res) => {
console.log("RESPONSE ==== : ", res);
})
.catch((err) => {
console.log("ERROR: ====", err);
})
All status codes above 400 will be caught in the Axios catch block.
Also, headers are optional for the post method in Axios
You can also use interceptors to pass the headers
It can save you a lot of code
axios.interceptors.request.use(config => {
if (config.method === 'POST' || config.method === 'PATCH' || config.method === 'PUT')
config.headers['Content-Type'] = 'application/json;charset=utf-8';
const accessToken = AuthService.getAccessToken();
if (accessToken) config.headers.Authorization = 'Bearer ' + accessToken;
return config;
});
Shubham's answer didn't work for me.
When you are using the Axios library and to pass custom headers, you need to construct headers as an object with the key name 'headers'. The 'headers' key should contain an object, here it is Content-Type and Authorization.
The below example is working fine.
var headers = {
'Content-Type': 'application/json',
'Authorization': 'JWT fefege...'
}
axios.post(Helper.getUserAPI(), data, {"headers" : headers})
.then((response) => {
dispatch({type: FOUND_USER, data: response.data[0]})
})
.catch((error) => {
dispatch({type: ERROR_FINDING_USER})
})
We can pass headers as arguments,
onClickHandler = () => {
const data = new FormData();
for (var x = 0; x < this.state.selectedFile.length; x++) {
data.append("file", this.state.selectedFile[x]);
}
const options = {
headers: {
"Content-Type": "application/json",
},
};
axios
.post("http://localhost:8000/upload", data, options, {
onUploadProgress: (ProgressEvent) => {
this.setState({
loaded: (ProgressEvent.loaded / ProgressEvent.total) * 100,
});
},
})
.then((res) => {
// then print response status
console.log("upload success");
})
.catch((err) => {
// then print response status
console.log("upload fail with error: ", err);
});
};
axios.post can accept 3 arguments that the last argument can accept a config object that you can set header.
Sample code with your question:
var data = {
'key1': 'val1',
'key2': 'val2'
}
axios.post(Helper.getUserAPI(), data, {
headers: {Authorization: token && `Bearer ${ token }`}
})
.then((response) => {
dispatch({type: FOUND_USER, data: response.data[0]})
})
.catch((error) => {
dispatch({type: ERROR_FINDING_USER})
})
If you are using some property from vuejs prototype that can't be read on creation you can also define headers and write i.e.
storePropertyMaxSpeed(){
axios
.post(
"api/property",
{
property_name: "max_speed",
property_amount: this.newPropertyMaxSpeed,
},
{
headers: {
"Content-Type": "application/json",
Authorization: "Bearer " + this.$gate.token(),
},
}
)
.then(() => {
//this below peace of code isn't important
Event.$emit("dbPropertyChanged");
$("#addPropertyMaxSpeedModal").modal("hide");
Swal.fire({
position: "center",
type: "success",
title: "Nova brzina unešena u bazu",
showConfirmButton: false,
timer: 1500,
});
})
.catch(() => {
Swal.fire("Neuspješno!", "Nešto je pošlo do đavola", "warning");
});
};
Interceptors
I had the same issue and the reason was that I hadn't returned the response in the interceptor. Javascript thought, rightfully so, that I wanted to return undefined for the promise:
// Add a request interceptor
axios.interceptors.request.use(function (config) {
// Do something before request is sent
return config;
}, function (error) {
// Do something with request error
return Promise.reject(error);
});
