Updates: HiveFreedomDollar
- Day before yesterday, I talked about how upload an image from Flutter-webapp with @keychain
- With @keychain, it was very easy. One javascript function does it all.
- However, with @hiveauth, it's not that straight forward.
- In this post, I'll illustrate the steps I've taken to upload the image.
- Please correct me if I'm wrong somewhere.
Background before diving into the code
- Flutter Web App has the Socket connection of @hiveauth.
- Only Javascript side of code has crypto utilities. I've tried crypto on dart side but results aren't matching. I'll utilise javascript as much as possible.
- Only Javascript side of code has proper buffer processing. I've tried dart buffers & have failed. I've also tried AI's suggestion which didn't work. After wasting good amount of time, I decided to utilise javascript side of Buffer feature.
Pseudocode for image upload using hiveauth on flutter webapp
FlutterApp -> JavaScript: OpenImagePicker
note:
- FlutterApp informs JavaScript to open image picker.
- WebApp code - It opens up an image picker.
- User selects file.
- After file is selected, we get buffer of it.
- We get base64 of selected file.
- We prepare buffer to sign
- Buffer to sign - is converted to JSON & JSON to Base64
JavaScript -> FlutterApp: Buffer2SignBase64, FileBase64, file name
note:
- FlutterApp receives Buffer to sign as base64.
- FlutterApp decodes base64 of buffer to sign & obtains JSON
- FlutterApp preserves these 3 values.
FlutterApp -> HiveAuth: Sign Buffer
note:
- FlutterApp sends this data to HiveAuth with a signing challenge request
- In Signing Challenge request, we attach Json of buffer to sign & request to sign with Posting key.
HiveAuth -> FlutterApp: Signed Buffer
note:
- FlutterApp receives signature of buffer to be signed.
FlutterApp -> JavaScript: Signature, Base64 of Image, File Name
note:
- FlutterApp sends signature, base64 of image & file name to JavaScript side of code.
- JavaScript side of code prepares a proper form-data-request after creating file-blob object from given base64.
- JavaScript side of code uploads image
JavaScript -> FlutterApp: Uploaded URL
note:
- JavaScript side of code returns the URL of uploaded image.
- FlutterApp now can use this URL as an attachment in the post.
Async function to get Buffer of a File
async function getFileBuffer(file) {
return new Promise(function (resolve, reject) {
var reader = new FileReader();
reader.onload = async () => {
const content = window.buffer.Buffer.from(reader.result, "binary");
resolve(content);
};
reader.readAsBinaryString(file);
});
}
Async function to get Base64 of a File
async function getFileBase64(file) {
return new Promise(function (resolve, reject) {
const reader = new FileReader();
reader.readAsDataURL(file);
reader.onload = () => resolve(reader.result);
reader.onerror = reject;
});
}
Getting Data to Sign for HiveAuth after image is selected
async function openImagePickerForWebAppForHiveAuth(id, accountName) {
return new Promise(function (resolve, reject) {
var input = document.createElement("input");
input.type = "file";
input.onchange = (e) => {
var file = e.target.files[0];
getFileBuffer(file).then((content) => {
getFileBase64(file).then((base64) => {
const prefix = window.buffer.Buffer.from(
"ImageSigningChallenge"
);
const buf = window.buffer.Buffer.concat([prefix, content]);
// we are converting it to base64
// to avoid double-json-encoding-decoding failures.
const bufJsonBase64 = btoa(JSON.stringify(buf));
let retResp = JSON.stringify({
id: id,
valid: true,
accountName: accountName,
data: {
bufJsonBase64: bufJsonBase64,
base64: base64,
fileName: file.name,
},
});
resolve(retResp);
});
});
};
input.click();
});
}
- So, From the given swimlane diagram, I was able to only complete step 1 & step 2.
- I am yet working on Step 3 - get buffer signed by @HiveAuth
- As soon as I'm done with everything, I'll update this post.
Updates: HiveCurators - DiscordBot
- HiveCurators - DiscordBot is doing well
- No outages were reported
- HiveCurators With DiscordBot was able to successfully curate approximately 49 posts today.
- Curation report is added below in the post
- I've staked ALIVE.
- Those who read my post & reply, I'll reward them with Alive & Pizza tokens.
- Those who reply to curation comments, they will be randomly rewarded with Alive token & Pizza tokens.
- To these users, @himalayanwomb, @thebigsweed, @irvet, @jlufer, @saranegi, I sent 0.05 Hive Power - to reward them for their contribution on Hive Communities.
- Here is the screenshot, from Ecency Wallet, indicating the same.
Updates: Video Encoder Nodes
- I'm running 12 powerful video encoder nodes for 3Speak Community Members.
- Monthly internet bandwidth usage which exceeds 15 TB, Maintenance cost, Electricity backup, Internet backup, Depreciation cost - it's all on me.
- Yesterday (14-Apr-2024) 3Speak published total 139 videos
- My video encoder nodes encoded 110 videos from 139 videos published.
How is @sagarKothari88 doing?
- Today, I went to out to find new pre-schools for my son.
- I find this school decent & nearby.
- I asked as much as possible & found satisfactory answers.
- But I insisted on trying out the school for a month & to convince them about this idea, I suggested to give us options for summer camp.
- Except that, Today, most of my time spent in solving @hiveuath related challenges in current project.
