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 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);
});
}
uploadPictures = (event) => {
let formData = new FormData();
let image = event.target.files[0];
let color = [0,153,255];
formData.append('image', image);
formData.append('color', color);
let url = FormatUrl(`/store_image?`, true)
fetch(url, {
method: 'post',
headers: {
"Content-Type": "multipart/form-data",
"Accept": '*/*',
"type": "formData",
},
body:formData,
})
.then(response => response.json())
.then(res => {
this.setState({
imgSrc: res.image_url
})
}).catch(err => {
console.log(err)
})
}
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
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);
});
};
constructor(props) {
super(props);
this.state = {text: this.props.navigation.state.params.text,
name:this.props.navigation.state.params.name};
}
manage = () => {
Alert.alert('done')
Actions.reset('mainScreen');
fetch("http://ip/api/confirm", {
method: "POST",
headers: {
Accept: "application/json",
"Content-Type": "application/json"
},
body: JSON.stringify({
name: this.props.navigation.state.params.name,
text:this.props.navigation.state.params.text
})
})
.then(response => response.json())
.catch(error => {
console.error(error);
});
}
i want to do this
when i press in button go to manage function
and post the text and the name to my api i dont know how can i pass them
its give me this error :
network request failed
any help please
I recommend you to use axios to make network requests.
Installing:
npm i -S axios
Performing a POST request:
import axios from 'axios';
axios({
url: 'http://ip/api/confirm',
method: 'post',
data: {
name: this.props.navigation.state.params.name,
text: this.props.navigation.state.params.text,
},
headers: {
Accept: 'application/json',
'Content-Type': 'application/json',
}
})
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error);
});
var resp = await manage(this.props.session.userId,this.props.session.ApiKey,"hi","hello");
if (resp.status == 200){
var respBody = await resp.json();
console.log('Fetch Todo response '+respBody);
}
API in separate file
export async function manage(userId,ApiKey,query,query1) {
var url ="http://www.example.com/getdata";
const params = {
search:query,
searches:query1
};
var formBody = [];
for (const property in params) {
const encodedKey = encodeURIComponent(property);
const encodedValue = encodeURIComponent(params[property]);
formBody.push(encodedKey + "=" + encodedValue);
}
formBody = formBody.join("&");
const requestOptions = {
'method': 'POST',
'headers': {
'Content-Type': 'application/x-www-form-urlencoded'
// 'Content-Type': 'application/json'
},
'body': formBody
};
requestOptions.headers["userid"] = userId
requestOptions.headers["apikey"] = ApiKey
try {
var resp = await fetch(url, requestOptions);
return resp;
}
catch (err) {
console.log("Request Failed: " + err);
return err;
}
}
Is it possible to upload file (images) to server with react-native using FormData? Tried to use it like this:
var data = new FormData();
data.append('file', file);
console.log(JSON.stringify(data));
var id = 5;
fetch('http://192.168.1.104:3000/app/complaint/uploadFile?id='+id,{
method:'POST',
body: data,
headers: {
'Accept': 'application/json',
'Content-Type': 'multipart/form-data;',
},
});
For React, FormData works as expected but for React-Native not working.
I have also tried (used in react - working)
const data = fetch('http://192.168.1.104:3000/app/complaint/uploadFile?id='+id, {
credentials: "same-origin",
method:'POST',
body: dataval,
timeout: 1000000000,
});
But nothing works,
In the back-end server, I am upload using
var d = require('domain').create()
d.run(function safelyUpload () {
var file=req.file('file').upload({dirname: path.resolve(sails.config.appPath, folder),
}, function whenDone(err, uploadedFiles) {
if (err) return res.serverError(err);
else{
sails.log.debug('Complaint File data : ' +util.inspect(uploadedFiles, {showHidden: true,depth: null}));
}
});
});
Is there any other ways
Here is example to upload image using Fetch API
const photo = {
uri: user.profilePicture,
type: 'image/jpeg',
name: 'photo.jpg',
};
const form = new FormData();
form.append("ProfilePicture", photo);
fetch(
URL,
{
body: form,
method: "PUT",
headers: {
'Content-Type': 'multipart/form-data',
'Authorization': 'Bearer ' + user.token
}
}
).then((response) => response.json())
.catch((error) => {
alert("ERROR " + error)
})
.then((responseData) => {
alert("Succes "+ responseData)
}).done();
