base64

问题 I have a zip file, which contains one CSV file. I need to Base64 encode this zip file to send to eBay (using their API). I used this website: http://www.opinionatedgeek.com/DotNet/Tools/Base64Encode/ which works nicely, I upload my zip file and it returns a base64 encoded string which eBay likes. I need to do what this website does, but using Classic ASP and VB Script. I already have a base64 encode function, from here: http://www.motobit.com/tips/detpg_base64encode/ so I don't need a script

问题 I want to crypt privateKey & publicKey to sha1 in base64 with Swift, but the output is not the one I see in PHP urlencode base64_encode which I tried in Codecademy:"https://www.codecademy.com/courses/web-beginner-en-StaFQ/0/3?curriculum_id=5124ef4c78d510dd89003eb8". Pls see the following codes in Swift and Codecademy: Swift: //pls see func dataFromHexadecimalString() details here "http://stackoverflow.com/questions/26501276/convert-string-to-hex-string-in-swift/26502285#26502285" extension

问题 I want to return a pdf from a AWS Lambda function, and I use API Gateway for calling it from a any browser. I have a aws lambda function in c# that returns an API Gateway Response which body is a pdf in base64 encoded string . So far the endpoint returns a file with .pdf extension but not in binary. Instead, is a text file with the base64 string. The headers i'm returning from the c# code are: var headersDic = new Dictionary<string, string>(); headersDic.Add("Content-type", "application/pdf")

问题 I am scraping image src, title, price etc from website but it gives base64 string in place of image src. When i'm appending all these scraped data to uri, it shows error long uri. How to slow this problem? 回答1: If you're getting a base64 string as the img src, it sounds as though the image is encoded inline. data: URIs are a very useful way to embed small items of data into a URL—rather than link to an external resource, the URL contains the actual encoded data. An HTML fragment embedding a

问题 I am given this number 427021005928, which i am supposed to change into a base64 encoded string and then decode the base64 string to get a plain text. This decimal value 427021005928 when converted to binary gives 110001101101100011011110111010001101000 which corresponds to 'Y2xvdGg=', which is what i want. Got the conversion from (https://cryptii.com/pipes/binary-to-base64) And then finally i decode 'Y2xvdGg=' to get the text cloth. My problem is i do not have any idea how to use Python to

问题 I know this question has been asked much times, but please look once in my problem. I am sending base64 image data from angular to python flask but when I am processing that base64 data on flask server(python3) then it is giving me the error TypeError: expected bytes-like object, not str My Javascript code is: window['__CANVAS'].toDataURL("image/png"); Output of the above line is: "data:image/png;base64,iVBORw0KGgoAAAANSUhEUg....." I am receiving same data on flask server as string. Code on

问题 I have a problem. I would like to attach an image to an email and also display it inline, with some other php-generated content. The problem is I don't have the slightest ideea how to use inline a file attachment array used by wp_mail to attach. My solution was to encode the images in base64 and put them inline the HTML like this: <img alt="The Alt" src="data:image/png;base64,*etc*etc*etc" /> But the problem is that Gmail / Outlook remove the src data from the image. So it lands as <img alt=

问题 My java programmer converted an excel file to binary and sending the binary content to me. He used sun.misc.BASE64Encoder and sun.misc.BASE64Decoder() for encoding. I need to convert that binary data to a data frame using python. the data looks like, UEsDBBQABgAIAAAAIQBi7p1oXgEAAJAEAAATAAgCW0NvbnRlbnRfVHl........ I tried bas64 decoder but not helped. my code: import base64 with open('encoded_data.txt','rb') as d: data=d.read() print(data)

问题 I am using PowerShell to make a condition selection, need to judge whether the string is Base64 encoded, What is the easiest and most direct way? if ($item -is [?base64]) { # handle strings or characters } 回答1: The following returns $true if $item contains a valid Base64-encoded string , and $false otherwise: try { $null=[Convert]::FromBase64String($item); $true } catch { $false } The above uses System.Convert.FromBase64String to try to convert input string $item to the array of bytes it
