Get all contacts from phonebook and upload to server but got following error.
While append image in request body FormData
Tried code
pass file url contact thumbnailPath
const path = con.thumbnailPath
body.append('image', {
uri: path,
type: 'image/jpeg',
name: 'photo.jpg',
type: 'multipart/form-data'
})
Tried code
pass file url contact thumbnailPath without "file://"
const path = con.thumbnailPath.replace('file://', '')
body.append('image', {
uri: path,
type: 'image/jpeg',
name: 'photo.jpg',
type: 'multipart/form-data'
})
Tried code
check file exist on path or not with using react-native-fs
if (con.thumbnailPath != '') {
let isExist = RNFS.exists(con.thumbnailPath)
if (isExist) {
const path = con.thumbnailPath.replace('file://', '')
console.log("Exist", path)
body.append('image', {
uri: path,
type: 'image/jpeg',
name: 'photo.jpg',
type: 'multipart/form-data'
})
}
}
Request
fetch(url, {
method: 'POST',
headers: {
'Authorization': token,
'token': token
},
body: params
})
.then((res) => res.json())
.then((json) => {
console.log("RESPONSE:- ", json)
if (json.response[0].status == 'false') {
let msg = json.response[0].response_msg
callback(new Error(msg), json.response[0])
}
else {
callback(null, json.response[0])
}
})
.catch((err) => {
console.log(err)
callback(err, null)
})
The issues comes from react-native@0.63.2
's internal bug.
A quick solution is to revert this commit: https://github.com/facebook/react-native/commit/31980094107ed37f8de70972dbcc319cc9a26339#diff-9a034658197479288c4d346a0eb4d98c
After manually revert this commit in node_modules
, recompile the app and the image uploading will be working without any issues.
Replace the function loadImageForURL
in /Libraries/Image/RCTLocalAssetImageLoader.mm
with the following:
- (RCTImageLoaderCancellationBlock)loadImageForURL:(NSURL *)imageURL
size:(CGSize)size
scale:(CGFloat)scale
resizeMode:(RCTResizeMode)resizeMode
progressHandler:(RCTImageLoaderProgressBlock)progressHandler
partialLoadHandler:(RCTImageLoaderPartialLoadBlock)partialLoadHandler
completionHandler:(RCTImageLoaderCompletionBlock)completionHandler
{
__block auto cancelled = std::make_shared<std::atomic<bool>>(false);
RCTExecuteOnMainQueue(^{
if (cancelled->load()) {
return;
}
UIImage *image = RCTImageFromLocalAssetURL(imageURL);
if (image) {
if (progressHandler) {
progressHandler(1, 1);
}
completionHandler(nil, image);
} else {
NSString *message = [NSString stringWithFormat:@"Could not find image %@", imageURL];
RCTLogWarn(@"%@", message);
completionHandler(RCTErrorWithMessage(message), nil);
}
});
return ^{
cancelled->store(true);
};
}
此问题已在 0.63.3 中修复 ✅
**For IOS** in
node_modules/react-native/Libraries/Image/RCTLocalAssetImageLoader.mm file
**Replace Below**
- -(RCTImageLoaderCancellationBlock)loadImageForURL:(NSURL *)imageURL
size:(CGSize)size
scale:(CGFloat)scale
resizeMode:(RCTResizeMode)resizeMode
progressHandler:(RCTImageLoaderProgressBlock)progressHandler
partialLoadHandler:(RCTImageLoaderPartialLoadBlock)partialLoadHandler
completionHandler:(RCTImageLoaderCompletionBlock)completionHandler
{
UIImage *image = RCTImageFromLocalAssetURL(imageURL);
if (image) {
if (progressHandler) {
progressHandler(1, 1);
}
completionHandler(nil, image);
} else {
NSString *message = [NSString stringWithFormat:@"Could not find image %@", imageURL];
RCTLogWarn(@"%@", message);
completionHandler(RCTErrorWithMessage(message), nil);
}
return nil;
}
**With**
- -(RCTImageLoaderCancellationBlock)loadImageForURL:(NSURL *)imageURL
size:(CGSize)size
scale:(CGFloat)scale
resizeMode:(RCTResizeMode)resizeMode
progressHandler:(RCTImageLoaderProgressBlock)progressHandler
partialLoadHandler:(RCTImageLoaderPartialLoadBlock)partialLoadHandler
completionHandler:(RCTImageLoaderCompletionBlock)completionHandler
{
__block auto cancelled = std::make_shared<std::atomic<bool>>(false);
RCTExecuteOnMainQueue(^{
if (cancelled->load()) {
return;
}
UIImage *image = RCTImageFromLocalAssetURL(imageURL);
if (image) {
if (progressHandler) {
progressHandler(1, 1);
}
completionHandler(nil, image);
} else {
NSString *message = [NSString stringWithFormat:@"Could not find image %@", imageURL];
RCTLogWarn(@"%@", message);
completionHandler(RCTErrorWithMessage(message), nil);
}
});
return ^{
cancelled->store(true);
};
}

Like and Love , if it work
I have the same issue which perfectly reproducible on one of the iPhone 7 on my react-native project. It's strange but another iPhone 7's works perfectly as well as all Android devices.
My code:
formdata.append("file", {uri: photo.uri, name: name_img, type: 'image/jpeg' });
axios({
url: `${API}${'/upload'}`,
method: 'post',
headers: {
'Authorization': 'Basic ' + auth_token,
'Content-Type':'application/x-www-form-urlencoded'
},
data: formdata
}).then(response => this.saveRoute())
.catch(err => {
this.props.errorMessage({message: err})
}
})
Few things that I investigate:
try-catch
statement but seams it happened in Axios call.So, I tried to play with Timeout and was able to make it totally unreproducible with 300ms timeout before Axios call .
formdata.append("file", {uri: photo.uri, name: name_img, type: 'image/jpeg' });
setTimeout(() =>
axios({
url: `${API}${'/upload'}`,
method: 'post',
headers: {
'Authorization': 'Basic ' + auth_token,
'Content-Type':'application/x-www-form-urlencoded'
},
data: formdata
}).then(response => this.saveRoute())
.catch(err => {
this.props.errorMessage({message: err})
}
})
, 300);
I know that it's a workaround but may help others to understand the issue for more deep research.
我使用rn-fetch-blob
临时修复了这个问题,但这个问题存在于 0.63.2 版本中,我不想修补 node_modules 反应原生图像库。
To send file, you have to create a FormData and append your file into it. See EX: https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch#Uploading_a_file
I found solution. Just put delay when you post request.
let options = {}
options.headers = headers
options.method = 'POST'
let url = {SERVER_URL}
options.body = new FormData();
for (let key in data) {
options.body.append(key, data[key]);
}
setTimeout(() => {
fetch(url, options)
.then((response) => response.json())
.then((responseJson) => {
resolve(responseJson);
})
.catch((error) => {
let errParam = {}
errParam.errMsg = error.toString()
console.log(errParam)
resolve(errParam);
})
}, 1000);
将 React Native 更新到版本 0.63.3 时已修复错误
