I want to display the location base on the value that I get from getLocation but all I get is a blue screen if I assign for example
this.lat=25.7777, this.lng=26,777; but it does not if a did like this this.lat=this.LAT; this.lng=this.LNG; and it works fine one last thing l would like to mention that the datatype in the database is double and I have tried testing a text as well
lat:number;
lng:number;
LAT:any;
LNG:any;
constructor(public dataservice:DataService,private geolocation: Geolocation) {
this.dataservice.getLocation(ID)
.subscribe(data =>{this.LAT = data[0].lat,
this.LNG=data[0].lng
this.lat=this.LAT;
this.lng=this.LNG;
});
.html
<agm-map [latitude]="lat"[longitude]="lng" [zoom]="10"
[zoomControl]="true">
<agm-marker [latitude]="lat" [longitude]="lng"></agm-marker>
</agm-map>
You need to use Allow-Control-Allow-Origin in configuring your apache or Node.js server. rather then chrome plugin.
make changes in your server such that add that required header in response.

I cant find the solution anywhere and mine doesn't seem to work.
I just want to see the last plate string in the browser,or the few last plates,doesn't matter.
http://login:password#MY.IP/ISAPI/Traffic/channels/1/vehicleDetect/plates/
<AfterTime><picTime>2021-12-09T09:07:15Z</picTime></AfterTime>
I do have a plate taken exactly at the time im using in pictime,but the result im getting is;
This XML file does not appear to have any style information associated with it. The document tree is shown below.
<ResponseStatus xmlns="
http://www.hikvision.com/ver20/XMLSchema

</AfterTime>
</requestURL>
<statusCode>4</statusCode>

</ResponseStatus>
POSTMAN
Edit:
Are you certain that the ISAPI setting is enabled in the camera configuration?
It's not possible in the browser without some tool to send and process your API request.
Have you tried using Postman?
Don't forget to use a Digest Auth header.
from requests.auth import HTTPDigestAuth
import requests
url = 'http://<Your IP>/ISAPI/Traffic/channels/1/vehicleDetect/plates/'
data = "<AfterTime><picTime>20220912T192011+0400</picTime></AfterTime>"
r=requests.get(url, data =data,auth=HTTPDigestAuth('admin', 'password'))
print(r.text)
Try this one after enabling this setting in camera

I am uploading user profile image which is uploading and moved to storage/app/upload/images folder but when I am trying to display that image, below given error occurs.
Method App\Image::__toString() must not throw an exception, caught Illuminate\Database\Eloquent\JsonEncodingException
Here is my controller function for displaying
public function userProfile() {
$image = Image::all();
return view('frontend.layouts.Profile',compact('image'));
}
My view in which I am displaying image
#foreach($image as $images)
<img style="width:210px ; height: 230px " src="/storage/app/upload/images/{{$images->image}}" >
#endforeach
Please Upload your image in Public directory and then try to access that, it will work fine
There are three ways of making an image available to a user:
1. As a public asset
Here the image is made available to everyone. For instance your website logo, or landing page image would be accessed by all. So there is a url to the image that is easily accessed by all. These sort of files would go straight to public/img/ folder.
2. As a protected image available only if specific url is requested
Here user specific images would be accessed by specific people. Think of your members' personal photos that you want to make available only to the member herself or to some specific person. In this case you would store the images in storage/app/public and make a symlink using the artisan command php artisan storage:link You can read more on this here. Assuming that you store your files using random names using str_random() you would then generate urls to your image using the asset() helper like: echo asset('storage/X3jf5j5b2j3n.jpg'); Given that the file names are random, it would be hard to access this image by everyone excepting those who have the url generated using the asset() helper.
3. As a protected image made available using Intervention library
In this case you would first check if user is logged in and then dynamically load the image using Intervention via another protected route. So in your web routes you would first have the user authorization using auth middleware:
Route::group(['middleware' => 'auth'], function () {
Route::get('user', 'UserController#userProfile');
Route::get('images/{image}', 'UserController#serveImage'); // this route serves the image only if user is logged in
});
Then once your have installed Intervention library using composer, our UserController would look like:
use Intervention;
class UserController extends Controller
{
public function userProfile()
{
$images = Image::all();
return view('frontend.layouts.Profile', compact('images'));
}
public function serveImage($image)
{
$filename = storage_path('app/images/'.$image);
return Intervention::make($filename)->response();
}
}
You can see that the image is now being served from the storage folder and not public folder. So this method serveImage() is called only when the route defined earlier for it is authorized. Intervention then works its magic to read the image and send it as a http response.
Your view would change one tad bit to accommodate the new route end point that we defined called images. I assume here that you are storing the filename of the image in db by a field named filename:
#foreach($images as $image)
<img style="width:210px ; height: 230px " src="{{ url('/images/'.$image->filename) }}" >
#endforeach
Note: Do bear in mind that the preferred way to serve images is by using method 2 since it is much faster. You can use method 3 sparingly if you really don't want anyone to even stumble upon the files using the urls.
I am currently developing a Meteor React app, which is using the ostrio:files package to store audio files in a collection named Files. In another (regular mongo) collection, I am using the following code in the transform function to "join" the document with the link to the audio file:
transform: function(doc){
let curAudio = doc.audio;
let audioFile = Files.collection.findOne({_id: curAudio.file_id});
if(audioFile){
curAudio.audioLink = Files.link(audioFile);
curAudio.audioLength = audioFile.meta.length;
curAudio.audioSize = audioFile.size;
doc.audio = curAudio;
}
return doc;
}
This seems to work just fine, as the resulting audio.audioLink is something like
http://localhost:3000/cdn/storage/files/8Q7WwEXyJSkNWwFQa/original/8Q7WwEXyJSkNWwFQa.m4a
But when I try to do something like this
<audio controls preload="none" style={{width: "480px"}}>
<source src={track.audioLink} type="audio/mp4"/>
<p>Your browser does not support HTML5 audio.</p>
</audio>
To be able to play the file, everything works until I click the play button of the HTML5 player. Then, chrome outputs to the console, that the server returned 404 when the file was supposed to be loaded. I tested putting the link into the adress bar, here the server response is just
File Not Found :(
Does anyone have an idea how to fix this?
I found the answer:
My local Ubuntu installation was apparently configured to store uploaded files in /tmp, which didn't caus problems until I restarted the system or cleared my temporary files otherwise. Having the server recreate the DB fixed the problem.
I come here because I use the CameraPreview class from ionic-native in my ionic 2 project to take a picture, and I actually struggle with the path of the picture which is something like : assets-library://asset/asset.JPG?id=...
That type of URL is obviously impossible to render in the DOM, and I want to know how to convert it into a supported URL for the img or ion-img tag.
I tried to convert it using File.readAsDataURL() as it is suggested in the following links, but the promise return an empty string.
https://www.npmjs.com/package/cordova-camera-preview
http://ionicframework.com/docs/v2/native/file/
You can load it via http as a Blob and then set that as the src for an img.
Example below:
this.http.get(fileURI, new RequestOptions({responseType:ResponseContentType.Blob}))
.subscribe(
data => {
var blob = data.blob();
this.previewImage = this.sanitize(URL.createObjectURL(blob));
this.cd.detectChanges();
});
Make note of the sanitize function. This is required to bypass default browser security - see https://stackoverflow.com/a/37432961/3446442
In this example the img tag is bound to the previewImage variable:
<div [style.width.px]="cameraSize" [style.height.px]="cameraSize">
<img id="preview" [src]="previewImage">
</div>
This should be fairly simple though it is completely stumping me.
I have a backend Laravel installation running on localhost:8000
I have a front end Angular app running on localhost:9001.
I have some 'static' images I have included in my seed data (eg.
'1', 'user.png'), these images are being rendered perfectly in my front end (they are also served from the exact place my image uploads are going).
The URL I am currently serving images from is http://localhost:8000/images/{filename}
I can upload images from the front to the back end and they appear in the DB and the image is being put in the filesystem, I'm populating the correct URL in my front end (as evidenced by the previous URL).
My uploaded images are not being shown.
In my logs I am getting:
[2015-01-20 18:13:49] local.ERROR: NotFoundHttpException Route: http://localhost:8000/images/j249ae747ce28c317e02f1fb6d0a10c3.jpg [] []
[2015-01-20 18:13:49] local.ERROR: exception 'Symfony\Component\HttpKernel\Exception\NotFoundHttpException'
I tried a method in my routes file, but couldnt see why, when I am already serving some images already?
I have also set all permissions to 755 on my /images folder.
Any ideas?
I'm not sure I follow every bit of multi-system interaction you have going on, but I'd drop back to first HTTP principles.
Try accessing the image URL directly.
http://localhost:8000/images/j249ae747ce28c317e02f1fb6d0a10c3.jpg
If the error in your browser (or your logs, if you're not developing with debug set to true) is
local.ERROR: NotFoundHttpException Route: http://localhost:8000/images/j249ae747ce28c317e02f1fb6d0a10c3.jpg
This means your web server couldn't find a file at images/j249ae747ce28c317e02f1fb6d0a10c3.jpg, and handed the request to Laravel. This means you need to figure out why your webserver can't see the file.
Assuming you're serving index.php from the public folder
Do you have a public/images/j249ae747ce28c317e02f1fb6d0a10c3.jpg file?
Are you sure? Copy and paste the path into terminal and to a ls public/images/j249ae747ce28c317e02f1fb6d0a10c3.jpg to make sure your brain isn't missing some subtle case issue
Are any errors showing up in your web server's logs (not Laravel's)
Can you create a text/html file in the images folder and serve it? If not, then you may not be pointing your web server at the folder you think you are.
Something like
http://localhost:8000/images/test.txt
http://localhost:8000/images/test.html
Some first principles debugging like that should point you in the right direction.
rm public/storage
php artisan optimize:clear
php artisan storage:link
This worked for me.
The problem is you haven't generated a url for your uploaded image
Try accessing your url like this
http://localhost:8000/storage/images/j249ae747ce28c317e02f1fb6d0a10c3.jpg
To generate the above url
Add this method \Storage::disk('public')->url(); method in your controller.This method accesses the public disk array which is found in Config\filesystems.php and it generates a url in the following format
http://localhost:8000/storage/images/j249ae747ce28c317e02f1fb6d0a10c3.jpg
For example the method below stores the image in the image folder and generates the url of the image path.
public function uploadImage(Request $request)
{
$request->validate(['image'=>'file|image|max:5000']);
$imageProfile = new ImageProfile();
if($request->hasFile('image') && $request->file('image')->isValid())
{
$image = $request->file('image')->store('images');
$imageProfile->image_profile_url = \Storage::disk('public')->url($image);
$imageProfile->save()
}
return response()->json($imageProfile,200);
}
The code returns a Json response below
{
"id": 13,
"image_profile_url ": "http://127.0.0.1:8000/storage/images/cxlogqdI8aodERsmw74nmEx7BkxkWrnyJLMH7sFj.jpeg",
"updated_at": "2020-01-13 16:27:37",
"created_at": "2020-01-13 16:27:37",
}
Try to copy the url and test it in postman.
