ネイティブイメージのアップロードに反応する

Question

カメラロールまたは自分のAPIから画像をアップロードする際に問題が発生しています。ここに私が現在使っているコードがあります。カメラのロールとカメラの両方から画像データを取得できます。私はちょうどサーバーにデータを投稿する問題があります。私はどこが混乱しているのか分かりません。ここで

    DeviceEventEmitter.addListener('RNUploaderProgress', (data) => { 
     const bytesWritten = data.totalBytesWritten;

は、ワイヤの他端に来て何Fetch API

var photo = { 
    uri: user.profilePicture, 
    type: 'image/jpeg', 
    name: 'photo.jpg', 
}; 

var form = new FormData(); 
form.append("ProfilePicture", photo); 

fetch(
    Constants.API_USER + 'me/profilePicture', 
    { 
    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();
