i am using the following code to but i keep getting in android, which was showing "Network request failed", but it was no problem if i not append photo file data in the FormData. Why I am getting this problem?
const data = new FormData();
data.append("name", "testName"); // you can append anyone.
data.append("photo", {
uri: 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAADMAAAAzCAYAAAA6oTAqAAAAEXRFWHRTb2Z0d2FyZQBwbmdjcnVzaEB1SfMAAABQSURBVGje7dSxCQBACARB+2/ab8BEeQNhFi6WSYzYLYudDQYGBgYGBgYGBgYGBgYGBgZmcvDqYGBgmhivGQYGBgYGBgYGBgYGBgYGBgbmQw+P/eMrC5UTVAAAAABJRU5ErkJggg==',
type: 'image/png', // or photo.type
name: 'testPhotoName.png'
});
fetch('https://ptsv2.com/t/1gfl7-1544694996/post', {
method: "post",
body: data
}).then(res => {
console.log(res);
});

I get the following error when I set the 'Content-Type' as 'multipart/form-data' in react-native.
Below is my code -
const formData = new FormData();
formData.append('org_id', org_id);
formData.append('ans', userAns);
formData.append('remark', userRemark);
formData.append('img', userImg);
files.forEach(file => {
formData.append('files', {
name: file.fileName,
type: file.type,
uri: file.uri,
});
});
const resp = await multiPartInstance({
method: 'PUT',
url: `${apiBaseUrl}/installation/${Iid}/answer/${qid}`,
data: formData,
});
return Promise.resolve(true);
I am using axios for calling apis. multiPartInstance is an axios instance -
const multiPartAccessToken = async (config: AxiosRequestConfig) => {
config.headers = {
Accept: 'application/json',
access_token: useTokenStore.getState().accessToken,
'Content-Type': 'multipart/form-data;',
};
config.timeout = 30000;
return config;
};
I've tried the above with fetch also but I keep getting the same error. The strangest part is that this request hits the server, server sends a response too but I get this error react-native side. I've noticed if I don't use FormData I don't get any error. But I need to use FormData as I have to upload image files.
Environment Details -
Windows version 21H2 (OS Build 22000.376)
react-native 0.66.3
react 17.0.2
axios ^0.24.0
react-native-image-picker ^4.3.0 (used for selecting images)
Flipper version 0.99.0
I've tried the solutions posted on below forums but they didn't work for me.
request formData to API, gets “Network Error” in axios while uploading image
https://github.com/facebook/react-native/issues/24039
https://github.com/facebook/react-native/issues/28551
I am as follow and works perfectly:
const oFormData = new FormData();
images.map((val, index) => {
oFormData.append("image", {
uri: val.uri,
type: val.type,
name: val.fileName
});
});
return axios.post(postServiceUrl, oFormData);
Somehow react-native-blob-util doesn't give this error. I modified my code as below -
import ReactNativeBlobUtil from 'react-native-blob-util';
const fileData = files.map(file => {
return {
name: 'files',
data: String(file.base64),
filename: file.fileName,
};
});
try {
const resp = await ReactNativeBlobUtil.fetch(
'PUT',
`${apiBaseUrl}/installation/${Iid}/answer/${qid}`,
{
access_token: useTokenStore.getState().accessToken,
'Content-Type': 'multipart/form-data',
},
[
...fileData,
// elements without property `filename` will be sent as plain text
{name: 'org_id', data: String(org_id)},
{name: 'ans', data: String(userAns)},
{name: 'remark', data: String(userRemark)},
{name: 'img', data: String(userImg)},
],
);
i'm using api platform to create end Point to handle images upload.
My api require a file type to make a post request.
This is an example of post request using post man :
I want to handle sending images with axios using react native.
I created a post request like this :
this.setState({
avatarSource: source,
});
console.log(this.state.avatarSource.uri);
const data = new FormData();
data.append('file', {
uri: this.state.avatarSource.uri,
// show full image path in my device
// file:///storage/emulated/0/Pictures/image-c40b64fc-6d74-46a7-9016-191aff3740dd.jpg
});
axios
.post(`${API.URL}/media_objects`, data, {
headers: {
'Content-Type': 'multipart/form-data',
},
})
.then((resp) => console.log(resp))
.catch((err) => console.log(err.message));
}
});
I'm sending the full path of image in my phone to the api but i got "Network Error"
I fixed the problem by commenting this line in ReactNativeFlipper.java :
NetworkFlipperPlugin networkFlipperPlugin = new NetworkFlipperPlugin();
NetworkingModule.setCustomClientBuilder(
new NetworkingModule.CustomClientBuilder() {
#Override
public void apply(OkHttpClient.Builder builder) {
// builder.addNetworkInterceptor(new FlipperOkhttpInterceptor(networkFlipperPlugin)); // add comment here and build android
}
});
client.addPlugin(networkFlipperPlugin);
client.start();
I'm trying to upload an image from storage to a restful API but I keep getting Network Request Failed on Android (which means the request doesn't even go through), haven't checked on iOS because I don't need that part yet. API is already working and has been tested with Postman.
The React Native code is:
body.append('vehicles',{
resource_id: 2,
resource: 'vehicles',
cat_file_id: fileId,
active: 1,
vehicles: photo, //<- photo value below
name: 'vehicles',
type: 'image/jpeg'
})
fetch(`${BASE_URL}/files`, {
method: 'POST',
headers: {
'Content-Type': 'multipart/form-data',
Accept: "*/*",
Authorization: 'Bearer '+auth
},
body: body
}).then(response => response.json())
.then(response => {
console.log('IMAGE RESPONSE', response)
})
.catch(error => console.log('ERROR', error))
The photo value looks like file:///storage/emulated/0/DCIM/...
The response:
ERROR TypeError: Network request failed
at XMLHttpRequest.xhr.onerror (fetch.umd.js:473)
at XMLHttpRequest.dispatchEvent (event-target-shim.js:818)
at XMLHttpRequest.setReadyState (XMLHttpRequest.js:574)
at XMLHttpRequest.__didCompleteResponse (XMLHttpRequest.js:388)
at XMLHttpRequest.js:501

at MessageQueue.js:111
at MessageQueue.__guard (MessageQueue.js:384)
at MessageQueue.callFunctionReturnFlushedQueue (MessageQueue.js:110)
On Postman the request looks something like this:
Already tried:
Removing Accept header
Changing Accept value to 'application/json'
Removing file:// from the image url
Added android:usesCleartextTraffic="true" to the manifest
Already checked:
No values are null or undefined
There is a working internet connection, all other network requests on the app are working fine
The Auth is correct
React Native version is 0.61.5
I found one missing line in your code let formData = new FormData();. but not sure is that the exact issue here.
By the way here is a sample working code from one of my project, and I customized it with your context.
Add your authentication
replace ImageURI with image path and URL_SAVE_IMAGE endpoint url
const newImage = {
resource_id: 2,
resource: 'vehicles',
cat_file_id: 1,
active: 1,
vehicles: ImageURI,
name: "my_photo.jpg",
type: "image/jpg",
};
let formData = new FormData();
formData.append("vehicles", newImage);
return fetch(URL_SAVE_IMAGE, {
method: 'POST',
headers: {
"Content-Type": "multipart/form-data"
},
body: formData
}).then(response => response.json());
it should work!
What is your fetch(${BASE_URL}/files` backend server .. This usually happens when trying to connect to the backend api on the localhost machine.. Even if you use the IP address of the localhost, it still persists, so it is better to use online server for testing or just use ngrok(https://ngrok.com/) to serve your backend localhost via internet.
in gradle.properties change the flipper version to 0.47.0
try with Xhr, it's working as expected!
const URL = "ANY_SERVER/upload/image"
const xhr = new XMLHttpRequest();
xhr.open('POST', url); // the address really doesnt matter the error occures before the network request is even made.
const data = new FormData();
data.append('image', { uri: image.path, name: 'image.jpg', type: 'image/jpeg' });
xhr.send(data);
xhr.onreadystatechange = e => {
if (xhr.readyState !== 4) {
return;
}
if (xhr.status === 200) {
console.log('success', xhr.responseText);
} else {
console.log('error', xhr.responseText);
}
};
Nothing worked for me except using the Expo FileSystem uploadAsync
uploadImage = async ({ imageUri } }) => FileSystem.uploadAsync(
apiUrl,
imageUri,
{
headers: {
// Auth etc
},
uploadType: FileSystem.FileSystemUploadType.MULTIPART,
fieldName: 'files',
mimeType: 'image/png',
});
Note - imageUri in format of file:///mypath/to/image.png
Happy days!
This is how I tried to POST an image as multipart/form-data to server.
var photo = { uri: this.state.avatarSource,
type: 'multipart/form-data',
name: 'photo.jpg', };
let formdata = new FormData();
formdata.append('attachment',photo);
fetch(url,
{ method: "POST",
headers: { 'Content-Type': 'multipart/form-data' },
body: formdata
}).then((response) => response.json())
.catch((error) => { alert("ERROR " + error) })
.then((responseData) => { alert("Succes "+ responseData) }).done();
But it shows an error : Expected dynamic type string but had type
object
After 2 days, trying so many things I made the code working with some modifications.
RNFetchBlob.fetch('POST', url, {
'Content-Type': 'multipart/form-data',
}, [
{ name: 'file', filename: 'photo.jpg', type: 'image/png', data: RNFetchBlob.wrap(src) }
]) .then((resp) => {
console.log(resp.text());
}).catch((err) => {
console.log(err);
});
As mentioned in the docs formData.append(name, value, filename);
The value field in it accepts USVString or Blob, since you're passing an object to it therefore it throws an error.
You need to convert your image to blob, append and upload it.
If you've got the base64 of the image, then you can convert it to a blob directly using the fetch api
fetch(base64URL)
.then(res => res.blob())
.then(blob => console.log(blob))
Otherwise you may checkout RN-fetch-blob, their multipart/ formData example.
I slightly modified the solution given by #unknown123. And it worked for me.
Here is the solution.
First, install npm package rn-fetch-blob
import RNFetchBlob from 'rn-fetch-blob';
RNFetchBlob.fetch('PUT', url, {'Content-Type': 'multipart/form-data'},
Platform.OS === 'ios' ? RNFetchBlob.wrap(filePath) :
`RNFetchBlob-${filePath}`)
Please note, in my case, I had different file paths for IOS and Android devices. We handle it in different ways using rn-fetch-blob
Sample filePath variable data for
IOS device -
"/Users/Niveditha/Library/Developer/CoreSimulator/Devices/B41EB910-F22B-4236-8286-E6BA3EA75C70/data/Containers/Data/Application/B88777C6-6B10-4095-AB67-BB11E045C1DE/tmp/react-native-image-crop-picker/img.jpg"
Android device -
"file:///storage/emulated/0/Android/data/com.uploadcameraroll/files/Pictures/img.jpg"
I want to upload file(image, textfile, pdf etc) with FormData() and fetch request. Progress event working fine after completed progress event it gives {"response":{"code":400,"api_status":0,"message":"Error while reading image."}} .
How I can resolve this issue here is my code.
let uploadUrl = 'http://myurl.com:8080/api/v1/upload';
const data = new FormData();
data.append('name', 'testName');
data.append('photo', {
uri: 'content://com.android.providers.media.documents/document/image-234.jpg',
type: 'image/jpeg',
name: 'testPhotoName'
});
futch(uploadUrl, {
method: 'post',
body: data
}, (progressEvent) => {
const progress = progressEvent.loaded / progressEvent.total;
console.log(progress);
}).then((res) => console.log(res), (err) => console.log(err));
