I implemented this feature. In React Native Expo. I used expo-image-picker & expo-permissions.
To implement in RN Expo environment is much more easier than Android Studio. However, I had some troubles on that.
these error were solved by checking server log file. I learned a lot about that.
However I still have technical difficulties for file_receive_transfer.
That is. 'How to know whether the conversion is done or not?'
and, I will solve this problem with async function.
for this work well. I would learn Node.js.
ll RN ll -> async upload -> async requestPicture llServerll -> requestConversion -> llGoogle Colabll
-> llserver ll ---- image --> ll RN ll
@hacking-racoon Can you write the comment describes transaction file format here? or you can just check and point out any wrong in my description below.
Values are just sample strings. please not focus on value, but key.
method: POST(maybe additional GET request after transform)
method.body{
'file': file {
'type': 'image/jpg',
'uri': <selectedPicture에 저장된 uri>,
'name': 'uploadimagetmp.jpg',
'token':
Additionally, I need some more information on the client's request.
There are entire process of appending body. (on upload prototype)
let uploadData = new FormData();
uploadData.append('submit', 'ok');
uploadData.append('file', { type: 'image/jpg', uri: this.state.selectedPicture, name: 'uploadimagetmp.jpg' });
It has only 2 key : 'submit', 'file'
If you require any other key&value, please add comments.
Draft of the JSON structure
'sketch (changed from file) ': {
'content_type': 'image/jpg',
'uri': \<uri address of sketch image>,
'name':
'category': String. should be one of 'bag', 'shoes', 'hat'. default: null(MUST selected by the user.) 'get_recommendation': Boolean. If true, we'll show other categories. default: True. 'pattern': { 'Is_color': Boolean. the backend part of reading 'image_info' is dependent on this. 'content_type': String. pattern is an image, image/jpg, image/png, etc. BUT must be 'text/plain' if pattern is a color. 'image_info(you can change the name as you want)': String. if is_color == true, 6-digit color information(RGB), else uri path of image. }
JSON data format is not mattered when well discussed and shared. don't afraid to say you should modify JSON format.
I implemented this feature. In android-java.
to make this feature work well, I'm studying React Java,
Afterwords, I will implement this feature in React Java.
I used 'xampp' to open my apache server.
I encoded image to base_64 format, and uploaded to my server. (using volley library)
well done!
To put in our application, However, It should be implemented by React Native.
To receive image files,
I needed to write upload.php
and I used Atom IDE.
