I send this request to the server:
fetch('/changeCountProductInCart', {
method: 'POST',
body: JSON.stringify({
product_id: this.dataset.product_id,
action: 'changeByInput',
nodeName: this.nodeName,
product_count: this.value
}),
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
}
}).then(res => {
if(res.ok) {
totalAmount();
} else if(!res.ok) {
return res.json();
}
}).then(body => {
this.value = body.stock;
});
I want to go to then only if the response from the server only is not in the range of 200-300,but I just started to delve into promise and can't find the answer to my question
P.S. I will be grateful for any help or hint
You need to catch the server error responses:
fetch('/changeCountProductInCart', {
method: 'POST',
body: JSON.stringify({
product_id: this.dataset.product_id,
action: 'changeByInput',
nodeName: this.nodeName,
product_count: this.value
}),
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
}
})
.catch(err => /* error getting server response*/);
I have been using fetch on the frontend to make a PUT request. My code looked like the following:
fetch(url, {
headers: {
'content-type': 'png',
},
method: 'PUT',
body: file,
})
I am trying to write the same using axios but doesn't seem to be working
await axios.put(url, {
data: {
body: file
},
headers: {
'content-type': 'png',
},
})
Take a look at the axios.put signature:
axios.put(url[, data[, config]])
The second argument is treated as data, so your headers end up as part of the request body.
Further, data: { body: file }, is redundant. axios.put()'s data argument is already treated as body.
So you can either do:
await axios.put(url, file,
{
headers: {
'content-type': 'png'
}
}
)
or:
await axios.put(url, {},
{
data: file,
headers: {
'content-type': 'png'
}
}
)
Or, for even more resemblance with fetch API,
await axios(url,
{
method: 'PUT',
data: file,
headers: {
'content-type': 'png'
}
}
)
I am trying to communicate with an API from my React application using Axios. I managed to get the GET request working, but now I need a POST one.
I need the body to be raw text, as I will write an MDX query in it. Here is the part where I make the request:
axios.post(baseUrl + 'applications/' + appName + '/dataexport/plantypes' + plan,
{
headers: { 'Authorization': 'Basic xxxxxxxxxxxxxxxxxxx',
'Content-Type' : 'text/plain' }
}).then((response) => {
this.setState({data:response.data});
console.log(this.state.data);
});
Here I added the content type part. But how can I add the body part?
Thank you.
Edit:
Here is a screenshot of the working Postman request
How about using direct axios API?
axios({
method: 'post',
url: baseUrl + 'applications/' + appName + '/dataexport/plantypes' + plan,
headers: {},
data: {
foo: 'bar', // This is the body part
}
});
Source: axios api
You can use postman to generate code. Look at this image. Follow step1 and step 2.
If your endpoint just accepts data that have been sent with Body (in postman), You should send FormData.
var formdata = new FormData();
//add three variable to form
formdata.append("imdbid", "1234");
formdata.append("token", "d48a3c54948b4c4edd9207151ff1c7a3");
formdata.append("rate", "4");
let res = await axios.post("/api/save_rate", formdata);
You can use the below for passing the raw text.
axios.post(
baseUrl + 'applications/' + appName + '/dataexport/plantypes' + plan,
body,
{
headers: {
'Authorization': 'Basic xxxxxxxxxxxxxxxxxxx',
'Content-Type' : 'text/plain'
}
}
).then(response => {
this.setState({data:response.data});
console.log(this.state.data);
});
Just have your raw text within body or pass it directly within quotes as 'raw text to be sent' in place of body.
The signature of the axios post is axios.post(url[, data[, config]]), so the data is where you pass your request body.
The key is to use "Content-Type": "text/plain" as mentioned by #MadhuBhat.
axios.post(path, code, { headers: { "Content-Type": "text/plain" } }).then(response => {
console.log(response);
});
A thing to note if you use .NET is that a raw string to a controller will return 415 Unsupported Media Type. To get around this you need to encapsulate the raw string in hyphens like this and send it as "Content-Type": "application/json":
axios.post(path, "\"" + code + "\"", { headers: { "Content-Type": "application/json" } }).then(response => {
console.log(response);
});
C# Controller:
[HttpPost]
public async Task<ActionResult<string>> Post([FromBody] string code)
{
return Ok(code);
}

You can also make a POST with query params if that helps:
.post(`/mails/users/sendVerificationMail`, null, { params: {
mail,
firstname
}})
.then(response => response.status)
.catch(err => console.warn(err));
This will POST an empty body with the two query params:
POST
http://localhost:8000/api/mails/users/sendVerificationMail?mail=lol%40lol.com&firstname=myFirstName

Here is my solution:
axios({
method: "POST",
url: "https://URL.com/api/services/fetchQuizList",
headers: {
"x-access-key": data,
"x-access-token": token,
},
data: {
quiz_name: quizname,
},
})
.then(res => {
console.log("res", res.data.message);
})
.catch(err => {
console.log("error in request", err);
});
This should help
You can pass the params like so
await axios.post(URL, {
key:value //Second param will be your body
},
{
headers: {
Authorization: ``,
'Content-Type': 'application/json'
}
this makes it easier to test/mock in Jest as well
I got same problem. So I looked into the axios document.
I found it. you can do it like this. this is easiest way. and super simple.
https://www.npmjs.com/package/axios#using-applicationx-www-form-urlencoded-format
var params = new URLSearchParams();
params.append('param1', 'value1');
params.append('param2', 'value2');
axios.post('/foo', params);
You can use .then,.catch.
For sending form data in the body, you can just format the data in url params like this 'grant_type=client_credentials&client_id=12345&client_secret=678910' and attached it to data in the config for axios.
axios.request({
method: 'post',
url: 'http://www.example.com/',
data: 'grant_type=client_credentials&client_id=12345&client_secret=678910',
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
},
})
The only solution I found that would work is the transformRequest property which allows you to override the extra data prep axios does before sending off the request.
axios.request({
method: 'post',
url: 'http://foo.bar/',
data: {},
headers: {
'Content-Type': 'application/x-www-form-urlencoded',
},
transformRequest: [(data, header) => {
data = 'grant_type=client_credentials'
return data
}]
})
This worked fine for me when trying to send authentication credential in body in raw json format.
let credentials = {
username: "your-username",
password: "your-password",
};
axios
.get(url, { data: credentials })
.then((res) => {
console.log(res.data);
})
Used in React js
let url = `${process.env.REACT_APP_API}/validuser`;
let body = JSON.stringify({
loginid: "admin",
password: "admin",
});
var authOptions = {
method: "post",
url: url,
data: body,
headers: {
"Content-Type": "application/json",
},
json: true,
};
axios(authOptions)
.then((resp) => {
console.log("response :- ",resp);
})
.catch((error) => {
alert(error);
});
axios({
method: 'post', //put
url: url,
headers: {'Authorization': 'Bearer'+token},
data: {
firstName: 'Keshav', // This is the body part
lastName: 'Gera'
}
});
There many methods to send raw data with a post request. I personally like this one.
const url = "your url"
const data = {key: value}
const headers = {
"Content-Type": "application/json"
}
axios.post(url, data, headers)
let url='<your domain.extension>';
let data= JSON.stringify('mydata');
axios
.get(url, { data })
.then((res) => {
console.log(res.data);
})
For me this solution works, i.e. JSON.stringify(your data) , just convert your raw data using JSON.stringify method.
I hope this works.
I am using react native to create an application to act as a website that currently exists (with a user interface that works on a phone). i am using the "fetch" method to send a Http POST request to get information from a web server. The web server sends a response but it doesn't include the response message:
I apologies that is an image but the debugger is not working for me.
The code used to send the request:
HttpRequest = (RequestURL, callback) => {
var AdminLoginBindingModel = {
usr: this.state.username,
pwd: this.state.password,
}
fetch(RequestURL,
{
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify(AdminLoginBindingModel)
})
.then((res) => {
callback(res);
})
.catch((error) => {
this.setState({Response: "Error: " + error});
})
}
The callback function in the parameters is just a function to change the state variable to display the information on the screen
ValidateResponse(response){
this.setState({Response: "Result: " + JSON.stringify(response),
displayMessage: "Success"});
console.log(JSON.stringify(response));
}
The Request being sent is "https://mibase-test.mibase.com.au/members/api/startSession.php?usr=&pwd="
The server responds with a json object regardless of a correct login or not
Edit:
Changing the response to
.then((res) => {
callback(res.json());
})
Result:
To get object from fetch response, you have to call res.json like following:
fetch(RequestURL, {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify(AdminLoginBindingModel)
})
.then(res => res.json()) // HERE
.then(obj => callback(obj))
But it occurs an error because response body itself is invalid json format. It contains some HTML tags:
{"member": {"username":"","password":"","key":"***","status":"No"}}<br><br>Username: <br>Key: ***
Please check the inplementation of server.
EDIT: full code here
const fetch = require("node-fetch")
HttpRequest = (RequestURL, callback) => {
const AdminLoginBindingModel = { usr: "foo", pwd: "bar" }
fetch(RequestURL, {
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify(AdminLoginBindingModel)
})
.then(res => res.json())
.then(obj => callback(obj))
.catch(error => console.log(error))
}
const ValidateResponse = response => console.log(JSON.stringify(response))
URL = 'https://mibase-test.mibase.com.au/members/api/startSession.php?usr=&pwd='
HttpRequest(URL, ValidateResponse)
response doesn't contain received data directly. It provides interface methods to retrieve it. For example use response.json() to parse response text as JSON. It will return promise that resolves to the parsed object. You won't need to call JSON.parse on it:
fetch(RequestURL,
{
method: 'POST',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
},
body: JSON.stringify(AdminLoginBindingModel)
})
.then((res) => {
return res.json();
}).then((obj) => {
console.log(obj);
});

I am trying to get output from the post request once the form has been submitted but I get a promise response rather than the actual data when posting the form
fetch('localhost/clients', {
method: 'post',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
},
body: JSON.stringify(formData)
}).then(response => {
console.info('Sending Message ...')
console.info(response.json())
}).catch (error => {
console.log(error)
})
The data gets passed to the backend however I want to return the data thats been outputted by the API server.
response.json() returns a Promise. You need to use it like below.
fetch('localhost/clients', {
method: 'post',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
},
body: JSON.stringify(formData)
}).then(response => {
return response.json();
}).then(jsonResponse => {
console.log(jsonResponse);
}).catch (error => {
console.log(error)
})
