base64

问题 I have base64 image and I want to return the image preview not the base64 code. I tried return response(base64_decode($results->getBase64Image()), 200, ['Content-Type' => 'image/png']); but it returns a weird output. 回答1: I have been use this.. for base 64 images )))) function store() { $data = $this->request->img; list($type, $data) = explode(';', $data); list(, $data) = explode(',', $data); $directory_bucekts = implode('/',str_split(strtolower(str_random(2)))); Storage::disk('public')-

问题 I want to take the base64 string and use it to display the image. Below is the HTML file. I want to use the base64 string and use it in the img tag: <ion-content> <ion-card> <img src={{imageFileBinary}} /> <ion-card-header> <form> <ion-input id="myform" type="file" name="file" (change)="postMethod($event.target.files)"></ion-input> </form> <ion-card-title>Nick</ion-card-title> </ion-card> </ion-content> I get imageFileBinary from the .ts file. Below is the .ts file: export class MyprofilePage

问题 I have been using react-native's binaryToBase64, but it doesn't exist in new react-native versions (such as 0.62.2). Any suggestion on what to use instead? I tried js btoa(), but results are different, any idea why? For example: btoa let output = btoa(input); input: Uint8Array(5) [0, 1, 2, 3, 4] output: MCwxLDIsMyw0 input: Uint8Array(5) [5, 6, 7, 8, 9] output: NSw2LDcsOCw5 binaryToBase64 let output = binaryToBase64(input); input: Uint8Array(5) [0, 1, 2, 3, 4] output: AAECAwQ= input:

问题 I have the error as "TypeError: list indices must be integers or slices, not str " while running a unit test on the following function. The following function is used to call the model that is saved in Google AI Platform. However, the data input has to be base64 serialized, hence, I include the get_serialized_example(raw) function within the tfx_test(request). Any help and advice are appreciated. Thanks in advance! def tfx_test(request): #User Inputs project = request.project model = request

问题 I took the Spentalkux challenge on https://2020.ractf.co.uk/. This is the first time I do a CTF challenge so I went through a solution on https://github.com/W3rni0/RACTF_2020/blob/master/readme.md#spentalkux When I receive this base64 string :

问题 I have a string that is base64 encoded. It looks like this: eyJibGExIjoiYmxhMSIsImJsYTIiOiJibGEyIn0= Any online tool can decode this to the proper string which is {"bla1":"bla1","bla2":"bla2"} . However, my Java implementation fails: import java.util.Base64; System.out.println("payload = " + payload); String json = new String(Base64.getDecoder().decode(payload)); I'm getting the following error: payload = eyJibGExIjoiYmxhMSIsImJsYTIiOiJibGEyIn0= java.lang.IllegalArgumentException: Input byte

问题 I am trying to make an installer using batch. Of course, an installer needs to consist of files that will be installed, so I'm thinking of encoding the files in base64, and simply decode them and write them to their destination. Of course, my work would be very easy if Windows had something like the base64 tool that Linux boxes contain. However, since it's simply not there, is there any way to decode base64 content completely using batch files? And how would I accomplish this? Any help is
