I have a React application where I am changing POST method to GET with the request body as it is. It works fine with POST request however when I change the method to GET, it gives me error-
message: "org.springframework.http.converter.HttpMessageNotReadableException: Required request body is missing: public
My Front End Code-
export const setData = (getData) => dispatch => {
axios({
method: 'GET',
url: 'http://localhost:8080/api',
headers: {
'Content-Type': 'application/json'
},
data: getData
})
.then (response => {
dispatch({
type: API_DATA,
payload: response.data
})
dispatch({
type: SET_SEARCH_LOADER,
payload: false
})
})
.catch(function(error) {
})
}
Can someone let me know what I am missing here. As per my understanding, http allows to have a request body for GET method.
As per my understanding, http allows to have a request body for GET method.
While this is technically true (although it may be more accurate to say that it just doesn't explicitly disallow it), it's a very odd thing to do, and most systems do not expect GET requests to have bodies.
Consequently, plenty of libraries will not handle this.
The documentation for Axois says:
// `data` is the data to be sent as the request body
// Only applicable for request methods 'PUT', 'POST', and 'PATCH'
Under the hood, if you run Axios client side in a web browser, it will use XMLHttpRequest. If you look at the specification for that it says:
client . send([body = null])
Initiates the request. The body argument provides the request body, if any, and is ignored if the request method is GET or HEAD.
If you want to send parameters with get request in axios, you should send parameters as params.
If you want to set "Content-type":"application/json" and send params with get request, you should also send an empty data object.
For example:
const AUTH_TOKEN = 'Bearer token'
const config = {
headers: {
'Content-Type': 'application/json',
'Accept': 'application/json',
'Authorization': AUTH_TOKEN,
},
data: {},
params: {
"post_id": 1
}
}
axios.get("http://localhost/api/v1/posts/", config)
This is not axios, the error origniates from the java backend you're talking to. The public field in your request body is missing.
If you just want to send the data as parameters (which would be odd), pass it using params instead of data (as shown here: https://github.com/axios/axios#example).
I personally don't think your API should support GET with a request body (talk to the devs and ask for documentation).

I'm working in Javascript (frontend) and have a colleague working in the backend with NodeJS.
When calling a GET request, he asks me to put the data in the body, but I could not figure out how to do that. (If I use this code to a POST request, it works fine).
Could you tell me if this is possible and how to do it? He says that it is possible, but I've googled a lot and could not find the correct way to do that.
ERROR that I get: "Failed to execute 'fetch' on 'Window': Request with GET/HEAD method cannot have body."
let URL = "http://localhost:3000/verifyUser";

You are using HTTP GET and sending a body.
If you want to send a body (JSON) you should use the PUT and POST.
The best will probably be to:
change your client code to method: "PUT"
change the server to access PUT request
If you want to know which one to chose look at this question:
( PUT vs. POST in REST)
If you wish to send a request with a body then you should make a POST-request and not a GET one. GET-request cannot have a body by its nature and primary goal.
All params of GET-request must be indicated in the URL itself only.
I'm making a POST request to a node.js server and I'm having trouble getting it to work. Here's my request:
const headers = {
'Accept': 'application/json',
'Content-Type': 'application/json',
'Authorization': 'this-can-be-anything',
};
export const postVote = (id, vote) =>
fetch(`${uri}/posts/${id}`, {
method: 'POST',
headers,
body: JSON.stringify({options: vote}),
}).then(response => response.json())
.then(data => data)
.catch(err => console.log(err));
The function accepts an 'id' and a 'vote', both strings. The id is being used as part of the URI in the request, and the vote is being supplied as options so the API knows what to do with it. Both of the arguments are being passed correctly:
id = '8xf0y6ziyjabvozdd253nd'
vote = 'upVote'
Here's a link to the GitHub repository for the server/API:
Udacity Readable API
and a screenshot of the network when firing the request:
UPDATE: Added the second screenshot which shows status 200. Though it shows this and appears to have been successful, it still doesn't post to the server and the information stays the same.
What you are looking at is the OPTIONS request in the network tab. For cross origin requests, every request if preceeded by an OPTIONS request which tells the calling client (browser, for example) if those HTTP methods are supported by the remote server for use in crosss origin context.
Check the other requests out. If the OPTIONS request was responded to correctly by the server, the browser must automatically follow up with your POST request
EDIT:
Also, the docs specify the param name to be option whereas in your screenshot it is coming up as options.
Further reading: CORS
Try declaring the headers as such:
var headers = new Headers({
'Content-Type': 'application/json',
'Authorization': 'this-can-be-anything',
})
For some reason, I can't get file transfers to work via fetch. My code is really simple:
export function updateProfilePicture(apiKey, userID, picture) {
let data = new FormData();
data.append('picture', picture);
return fetch(`${API_URL}/v1/${ROOT}/update_profile_picture/${userID}`,{
headers: {'Authorization': `Token token=${apiKey}`},
method: 'POST',
data: data
}).then(response => response.json());
}
However, the resulting request does not seem to include any file whatsoever. Am I missing something? In the above example, picture is instance an of File
There could be two reasons:
data field in Fetch API is called body. Use this instead of data property.
(optional) You need to add another header: 'Content-Type', 'multipart/form-data'
