I try to repeat QPSQL driver not loaded Qt but it does not helped me. I used x64 Postgresql and my Qt application also x64
m_dataBase.addDatabase("QPSQL");
m_dataBase.setHostName(g_hostName);
m_dataBase.setPort(g_databasePort);
m_dataBase.setDatabaseName(g_databaseName);
m_dataBase.setUserName(g_userName);
m_dataBase.setPassword(g_password);
qInfo() << "drivers:" << m_dataBase.drivers();
if( !m_dataBase.isDriverAvailable("QPSQL")) {
qWarning() << "Driver QPSQL is not available";
} else {
qInfo() << "QPSQL is available";
}
if (m_dataBase.open()) {
qInfo() << "Data base open SUCCESSFUL";
return true;
} else {
qWarning() << "Data base does not open";
qInfo() << "Last ERROR:" << m_dataBase.lastError().driverText();
}
I enabled
qputenv("QT_DEBUG_PLUGINS", "1");
for editional debug logs.
I update PATH variable in cmd
SET PATH=D:\PostgresLib\lib;%PATH%
SET PATH=D:\PostgresLib\bin;%PATH%
and after what I see in output:

The problem was in non initialized object QSqlDatabase m_dataBase;
fix:
instead of this string
m_dataBase.addDatabase("QPSQL");
I use
m_dataBase = QSqlDatabase::addDatabase("QPSQL");

I deployed a simple NFT smart contract on polygon mumbai testnet but when I am trying to verify it then It is showing an error. please guide me how to verify it...
This is the error which I am getting
PS C:\Users\Sumits\Desktop\truffle> truffle run verify MyNFT --network matic --debug
DEBUG logging is turned ON
Running truffle-plugin-verify v0.5.20

Reading artifact file at C:\Users\Sumits\Desktop\truffle\build\contracts\MyNFT.json
Failed to verify 1 contract(s): MyNFT
PS C:\Users\Sumits\Desktop\truffle>
This is my truffle-config.js
const HDWalletProvider = require('#truffle/hdwallet-provider');
const fs = require('fs');
const mnemonic = fs.readFileSync(".secret").toString().trim();
module.exports = {

network_id: "*", // Any network (default: none)
},
matic: {
provider: () => new HDWalletProvider(mnemonic, `https://rpc-mumbai.maticvigil.com`),
network_id: 80001,

}
},
plugins: ['truffle-plugin-verify'],
api_keys: {
polygonscan: 'BTWY55K812M*******WM9NAAQP1H3'
}
}
First deploy the contract:
truffle migrate --network matic --reset
I am not sure if you successfully deploy it to matic network, because your configuration does not seem to be correct:
matic: {
// make sure you set up provider correct
provider: () => new HDWalletProvider(mnemonic, `https://rpc-mumbai.maticvigil.com/v1/YOURPROJECTID`),
network_id: 80001,
confirmations: 2,
timeoutBlocks: 200,
skipDryRun: true
},
Then verify.
truffle run verify ContractName --network matic
ContractName should be the name of the contract, not the name of the file
please make sure you are putting the polygonscan api key in lowercase
I have a URL for my file type .ies that is uploaded on firebase storage and I want to read the content inside the file but when I hit URL on the browser it only returns the information about the file, not the content
Example link: https://firebasestorage.googleapis.com/v0/b/westgatedash-d1341.appspot.com/o/documents%2FIES%2FCDL2-45W-M-120V_IESNA2002.IES
but when I use query params alt=media it downloads that I don't want.
Are there any query params to get the data of the file? or any way to achieve the goal ?
According to the documentation, each call is different and for different purposes:
Listing objects:
To list the objects in a bucket:
curl -X GET -H "Authorization: Bearer OAUTH2_TOKEN" \
"https://storage.googleapis.com/storage/v1/b/BUCKET_NAME/o"
Downloading objects:
curl -X GET \
-H "Authorization: Bearer OAUTH2_TOKEN" \
-o "SAVE_TO_LOCATION" \
"https://storage.googleapis.com/storage/v1/b/BUCKET_NAME/o/OBJECT_NAME?alt=media"
The difference when hitting the endpoint is, precisely, the alt=media param. What I understand is that you might want to stream the object? If so, you can achieve it through the client libraries. For instance:
To handle the file on a Cloud Function you can follow this guide you will find more detailed info. As a summary, to download a file:
// Download file from bucket.
const bucket = admin.storage().bucket(fileBucket);
const tempFilePath = path.join(os.tmpdir(), fileName);
const metadata = {
contentType: contentType,
};
await bucket.file(filePath).download({destination: tempFilePath});
console.log('Image downloaded locally to', tempFilePath);
This will save the image to a temporary folder since this is the recommended way to do it.
Use gcs.bucket.file(filePath).download to download a file to a temporary directory on your Cloud Functions instance. In this location, you can process the file as needed.
EDIT
According to Downloads Documentation:
You can send download requests to Cloud Storage in the following ways:
Simple download: Downloading objects to a destination.
Streaming download: Downloading data to a process.
Sliced object download: Downloading large objects.
In the Docs, following the GitHub Repo: For C++ it shows a stream downloading:
void ReadObject(google::cloud::storage::Client client,
std::vector<std::string> const& argv) {
//! [read object] [START storage_download_file]
namespace gcs = google::cloud::storage;
[](gcs::Client client, std::string const& bucket_name,
std::string const& object_name) {
gcs::ObjectReadStream stream = client.ReadObject(bucket_name, object_name);
int count = 0;
std::string line;
while (std::getline(stream, line, '\n')) {
++count;
}
std::cout << "The object has " << count << " lines\n";
}
//! [read object] [END storage_download_file]
(std::move(client), argv.at(0), argv.at(1));
}
But for NodeJs, for some reason, it doesn't. I was not able to find any example of that. On the other hand there are other questions in SatckOverflow with the same question, i.e: this:
const {Storage} = require('#google-cloud/storage');
const storage = new Storage();
const bucket = storage.bucket(bucket);
const remoteFile = bucket.file(file);
let buffer = '';
remoteFile.createReadStream()
.on('error', function(err) {console.log(err)})
.on('data', function(response) {
buffer += response
})
.on('end', function() {
//console.log(buffer);
res.send(buffer);
})
issue:
console show "getTokens does not support retrieving tokens while signed-" error.
step:
1. run app with Android studio
2. log in AWS ( my app use amplify drop-in UI )
3. retrieve data from AWS via API Gateway --> result OK ( able to retrieve)
4. log out and log in again
5. retrieve data from AWS via API Gateway --> result NG ( show above error)
note:
my configuration file include: Cognito User pool and Identity pool. this is auto generate after keyin " amplify add auth" at CLI.
if i deleted Cognito Identity pool from configuration file, issue not happen.
May i know why ?
my configuration file:
{
"UserAgent": "aws-amplify-cli/0.1.0",
"Version": "1.0",
"IdentityManager": {
"Default": {}
},
"CredentialsProvider": {
"CognitoIdentity": {
"Default": {
"PoolId": "xxx",
"Region": "us-east-2"
}
}
},
"CognitoUserPool": {
"Default": {
"PoolId": "us-east-2_xxx",
"AppClientId": "xxx",
"AppClientSecret": "xxx",
"Region": "us-east-2"
}
}
}
sign-in code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_authentication);
AWSMobileClient.getInstance().initialize(getApplicationContext(), new Callback<UserStateDetails>() {
#Override
public void onResult(UserStateDetails userStateDetails) {
switch (userStateDetails.getUserState()) {
case SIGNED_IN:
Intent i = new Intent(Authentication.this, AvailableFlavor.class);
break;
case SIGNED_OUT:
showSignIn();
break;
default:
AWSMobileClient.getInstance().signOut();
showSignIn();
break;
}
}
#Override
public void onError(Exception e) {
}
});
}
private void showSignIn() {
try {
AWSMobileClient.getInstance().showSignIn(this,
SignInUIOptions.builder().nextActivity(LoginSuccess.class)
.build());
} catch (Exception e) {
// Log.e(TAG, e.toString());
}
}
}
I guess the end of the error is "getTokens does not support retrieving tokens while signed-"...out?
I had a similar error, please check if your identity poolId is correct (even if you're not using a guest access or if you only want to use the user pool functionality) in app -> src -> res -> raw -> amplifyconfiguration.json & awsconfiguration.json. You can find your poolId in your AWS console -> cognito -> manage identity pools -> click on your pool -> click on Sample code.:
I'm working on a Raspberry pi 3, I have a webpage that sends text data to a Chrome App, and everything works fine up to here.
After that the Chrome App should send that data to the serial port and here appears the error:
Error in event handler for runtime.onMessageExternal: TypeError: Cannot read property 'connect' of undefined
The problem could be that this is not a Chrome App, it's an Extension and it can't use this API cause only Chrome Apps have access to the hardware, but I followed this guide to make my first Chrome App (https://developer.chrome.com/apps/first_app), so maybe there's something i didn't understand or a step that i missed.
Here's my code, thanks in advance for the help!
manifest.json
{
"name": "Send serial data",
"description": "App to send serial data.",
"version": "1.0",
"manifest_version": 2,
"app": {
"background": {
"scripts": ["background.js"]
}
},
"icons": { "16": "img-16.png", "128": "img-128.png" },
"externally_connectable" : {
"matches": ["*://localhost/*"]
}
}
background.js
var msg ;
function openSend(data) {
var onConnect ;
onConnect = function(connectionInfo) {
_this.connectionId = connectionInfo.connectionId;
}
chrome.serial.connect("/dev/ttyAMA0", {bitrate: 115200}, onConnect);
chrome.serial.send(connectionId, convertStringToArrayBuffer(data), function(sendInfo) {
if(sendInfo.error) $.modal('<div id="title">Unable to send data: ' + sendInfo.error + '</div>')
});
}
chrome.runtime.onMessageExternal.addListener((message, sender, sendResponse) => {
console.log(message.data);
msg = message.data ;
openSend(msg);
});
Solved, i just forgot to put this line of code in my manifest.json:
"permissions":["serial"],
i want to host my own extension on my asp.net server (it's free web server, so i don't have access to machine.config etc.).
But the point of my problem is here. I put the packaged extension to server and i want use something like this:
protected void Page_Load(object sender, EventArgs e)
{
string file = Request.QueryString["f"];
if (file != null)
{
Response.Write("");
if (file == "0")
{
Response.ContentType = "application/x-chrome-extension";
Response.AddHeader("Content-Disposition", "attachment;filename=RemotePlay_extension.crx");
Response.TransmitFile("~/Extensions/Update/RemotePlay_extension.crx");
}
else
{
Response.ContentType = "application/x-chrome-extension";
Response.AddHeader("Content-Disposition", "attachment;filename=RemotePlay_extension.crx");
Response.TransmitFile("~/Extensions/RemotePlay_extension.crx");
}
}
}
But every time I get this error:
Source of extension manifest:
{
"name": "Remote Play",
"description": "DJ interface to use RP.",
"version": "0.0.0.2",
"update_url": "../Extensions/RemoteChrome_Update.xml",
"permissions": ["tabs", "http://*/*"],
"background": { "scripts": ["background.js"] },
"content_scripts": [{"matches": ["http://*/*"],"js": ["inject.js"]}],
"page_action": {"default_icon": "playico.png", "default_popup": "popup.html"},
"manifest_version": 2
}
What i'm doing wrong? Where is that error?
You can not trigger installation through Page_Load function and headers
You should have a link tag <link rel="chrome-webstore-item"
href="https://chrome.google.com/webstore/detail/apdfllckaahabafndbhieahigkjlhalf">
You can trigger installation through chrome.webstore.install(url, successCallback, failureCallback)
For more information check documentation.
