Here i am trying to upload image to backend using above function.
But it is not working. while it is working fine for postman.
I think something is wrong with my headers
Please have a look

I am trying to send an object from react to express server using node.js
this is my object:
const formData = {
location: location,
cost: cost,
email: email,
image: image,
};
This is my fetch post method :
fetch("http://localhost:5000/places", {
method: "POST",
headers: { "content-type": "application/json" },
body: JSON.stringify(formData),
})
.then((res) => res.json())
.then((data) => {
if (data.insertedId) {
alert("Plcae added successfully");
}
})
.catch((error) => {
console.error("Error:", error);
});
I can see the image file object in client site console but I am not getting that in expreess server.
You have to send your input data as FormData to share images/files to the backend.
function uploadImage() {
let formData = new FormData(yourFormData);
fetch("http://localhost:5000/places", {
method: "POST",
body: formData,
}).then((res) => res.json())
.then((data) => {
if (data.insertedId) {
alert("Plcae added successfully");
}
})
.catch((error) => {
console.error("Error:", error);
});
}
I want to make a post request to backend with all form data.
Uploading the images i get an array with data:
const normFile = e => {
const getFileList = e.fileList.map( i => i.originFileObj);
console.log('Upload event:', getFileList);
fetch('https:///uploadapi', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ images: getFileList })
})
.then(async response => {
const data = await response.json();
console.log(data, 'res data')
})
.catch(error => {
console.error('There was an error!', error);
});
if (Array.isArray(e)) {
return e;
}
return e && e.fileList;
};
Above is my code where i use Ant Design uploader.
But how to delete the File text before each object?
You have to use multipart/form-data header
Let's say you have an input
<input type="file" onChange={uploadFile}/>
And logical part:
uploadFile = (e) => {
const formData = new FormData();
formData.append('name_your_file', e.target.files[0])
fetch('https:///uploadapi', {
method: 'POST',
headers: { 'Content-Type': 'multipart/form-data' },
body: formData
})
}
I am available to upload image to server via postman:
Here is a picture of my postman config.
Postman Config
I am using Axios and here is my config:
uploadPhoto = () => {
let formdata = new FormData();
let i = {
uri: this.state.profilePhoto.uri,
type: "multipart/form-data",
name: `image.jpg`,
};
formdata.append("user[image]", i);
console.log("This is formdata", formdata);
Axios.put(EDIT_PROFILE_API, {
headers: {
"Content-Type": "multipart/form-data",
apisecret: this.props.api_secret,
},
body: formdata,
})
.then((response) => {
response.text().then((res) => {
console.log(res);
});
})
.catch((error) => {
console.log(error, "Image is not uploaded");
});
};
It gives me an error when i try upload it to server. What i am doing wrong?
I am getting this error message: enter image description here
so i want to upload
object as data
and file as Note
to api using axios
uploadToServer= () => {
const file =this.state.photo
let data2 ={sale_id:1,
note_type_id:4,
description:"test",
note_content_item:" hi from broker hub"
}
let data = new FormData()
data.append('data[sale_id]', '1')
data.append('data[note_type_id]', '4')
data.append('data[description]', "test")
data.append('data[note_content_item]', "test")
console.log(data)
axios({
url: api',
method: 'POST',
data: data,
headers: {
'Content-Type' : 'multipart/form-data',
'Authorization':'Basic YnJva2VyOmJyb2tlcl8xMjM='
}
})
.then(resp => console.log(resp.data.response))
.catch(error => console.error(error));
}
first i am trying with data without Note i can do it in postman
but with my code i got error
message: "Can not save file"
response_code: 10
i got this error only if i change the key from data to something else
when you are using react-native you don't need "form-data" package. Because react native polyfills standard FormData api and exports it as global.
second problem is axios converts form data automatically to string, so you need to use transformRequest config on request to override it.
import { AxiosRequestConfig } from "axios";
const FormData = global.FormData;
const axiosInstance = axios.create({
baseURL: 'example.com', // use with scheme
timeout: 30000,
headers: {
"X-Platform": 'iOS',
"X-App-Build-Number": '1.0.0',
},
});
const formData = new FormData();
formData.append("userId", "123456");
formData.append("file", {
uri: "/dev/sda/abc.png",
type: "image/png",
name: "abc.png",
});
const config: AxiosRequestConfig = {
method: "post",
url: "/process/start",
responseType: "json",
headers: {
'Content-Type': 'multipart/form-data',
// if backend supports u can use gzip request encoding
// "Content-Encoding": "gzip",
},
transformRequest: (data, headers) => {
// !!! override data to return formData
// since axios converts that to string
return formData;
},
onUploadProgress: (progressEvent) => {
// use upload data, since it's an upload progress
// iOS: {"isTrusted": false, "lengthComputable": true, "loaded": 123, "total": 98902}
},
data: formData,
};
// send post request and get response
const response = await axiosInstance.request(config);
You are not building FormData correctly, Try this:
let data = {sale_id:1,
note_type_id:4,
description:"test",
note_content_item:" hi from broker hub"
}
const formData = new FormData();
formData.append('data', JSON.stringify(data));
formData.append('Note', {
uri: "file://" //Your Image File Path
type: 'image/jpeg',
name: "imagename.jpg",
});
axios({
url : api,
method : 'POST',
data : formData,
headers: {
Accept: 'application/json',
'Content-Type': 'multipart/form-data',
'Authorization':'Basic YnJva2VyOmJyb2tlcl8xMjM='
}
})
.then(function (response) {
console.log("response :", response);
})
.catch(function (error) {
console.log("error from image :");
})
This might help you:
import {Platform} from 'react-native';
import axios from 'axios';
const upload = async readPath => {
console.log('path', readPath);
const URL = 'your-url';
const headers = {
headers: {
'Content-Type': 'multipart/form-data',
Accept: 'application/json',
Authorization: `Bearer ${projectSecret}`,
},
};
const formData = new FormData();
const file = {
uri:
Platform.OS === 'android' ? `file:///${readPath}` : readPath,
type: 'text/plain',
name: name,
};
formData.append('file', file);
await axios
.post(URL, formData, headers, {
timeout: 3000,
})
.then(async response => {
console.log(response.data);
})
.catch(error => {
console.log('error : ', error);
});
};
So I have to update some user info ,it works fine on postman but when I try to type it in react-native I must be doing something wrong in the body of the fetch method. In postman I set x-www-form-urlencoded and type the keys like this :
Key ----- Value
moto ----- test
and that seems to work,but when I try to do the same on my code I somehow fail at it,here is my code
updateUser(){
return fetch(url,{
method: "PATCH",
headers: {
"X-Auth-Token": bearerToken,
"Content-Type":"application/x-www-form-urlencoded"
},
body: JSON.stringify({
moto: this.state.moto
}
})
}
)
I get 200 response which means the call works but I must be seting the parameter moto wrong somehow.
Any ideas ?
"Content-Type":"application/x-www-form-urlencoded"
should be
"Content-Type":"application/json"
form-urlencoded is way different from your body: JSON.stringify().
You'll want to use a FormData object instead:
const body = new FormData();
body.append('moto', this.state.moto);
fetch(url, {
method: "PATCH",
headers: {
"X-Auth-Token": bearerToken,
"Content-Type": "application/x-www-form-urlencoded"
},
body,
})
APICall = () => {
fetch(‘Your http URL’, {
method: 'PATCH',
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json',
‘X-Auth-Token’: bearerToken,
},
body: JSON.stringify({
moto: this.state.moto
})
}).then((response) => response.json())
.then((responseJson) => {
if(responseJson.statuscode == 1) {
Alert.alert('Success');
} else {
Alert.alert(responseJson.message);
}
}).catch((error) => {
console.error(error);
});
}
finally fixed it by seting body to
body:
`moto=${this.state.moto}`
it appears that urlencoded headers require parameters in the form of
parameter1=value1¶meter2=value2
componentDidMount() {
return fetch(“Your URL”, {
method: 'post',
headers: {
"Content-type": "application/x-www-form-urlencoded; charset=UTF-8",
"Authorization": “token”
},
body: "firstName=Nikhil&favColor=blue&password=easytoguess"
})
.then((response) => response.json())
.then(function (data) {
alert(“Success”)
console.log('Request succeeded with JSON response', data);
})
.catch(function (error) {
alert("error occur")
console.log('Request failed', error);
});
}
const formData = new FormData();
formData.append('email', 'test#gmail.com');
formData.append('password', '123456');
fetch("https://test.com/api/login", {
method: 'post',
body: formData
})
.then(res => res.json())
.then(
(result) => {
console.log(result);
}).catch(err => {
console.log(err);
})
