Using actix-web's web::Bytes, I can get the payload from a form submission. It is a simple form with one input named username and another input named text. The raw bytes stream looks like this
b"username=User&text=%22Hello%2C+World%21%22"
The content in the text submitted is simply "Hello, World!".
Without using serde, what methods can I use to convert the above %22Hello%2C+World%21%22 into the intended string "Hello, World!"?
Your data is encoded as application/x-www-form-urlencoded. you can use a crate like form-urlencoded to parse it.
Example:
let x = form_urlencoded::parse("%23first=%25try%25");
println!("{:?}", x); // [("#first", "%try%")]

It is not possible to correctly transfer the Cyrillic alphabet to the post request. Letters are replaced with question marks.
Everything works well with numbers and the Latin alphabet.
name = 'иии.docx'
multipartRequestEntity.addPart('filename', new StringBody(name)) // return '???.docx'
name = 'fff.docx'
multipartRequestEntity.addPart('filename', new StringBody(name)) // return 'fff.docx'
How to correctly pass the Cyrillic alphabet in a post request?
Try by create the String with encoding, something like this:
name = new String('иии.docx', 'UTF-8')
Also, verify if the multipartRequestEntity has any method to set the encoding on the output.
So I have to go through a bunch of code to get some data from an iframe. the iframe has a lot of data but in there is an object called '_name'. the first key of name is 'extension_id' and its value is a big long string. the json object is enclosed in apostrophes. I have tried removing the apostrophes but still instead of 'extension_id_output' I get a single curly bracket. the json object looks something like this
Frame {
...
...
_name: '{"extension_id":"a big huge string that I need"} "a bunch of other stuff":"this is a valid json object as confirmed by jsonlint", "globalOptions":{"crev":"1.2.50"}}}'
}
it's a whole big ugly paragraph but I really just need the extension_id. so this is the code I'm currently using after attempt 100 or whatever.
var frames = await page.frames();
// I'm using puppeteer for this part but I don't think that's relevant overall.
var thing = frames[1]._name;
console.log(frames[1])
// console.log(thing)
thing.replace(/'/g, '"')
// this is to remove the apostrophes from the outside of the object. I thought that would change things before. it does not. still outputs a single {
JSON.parse(thing)
console.log(thing[0])
instead of getting a big huge string that I need or whatever is written in extension_id. I get a {. that's it. I think that is because the whole object starts with a curly bracket. this is confirmed to me because console.log(thing[2]) prints e. so what's going on? jsonlint says this is a valid json object but maybe it's just a big string and I should be doing some kind of split to grab whaat's between the first : and the first ,. I'm really not sure.
For two reasons:
object[0] doesn't return the value an object's "first property", it returns the value of the property with the name "0", if any (there probably isn't in your object); and
Because it's JSON, and when you're dealing with JSON in JavaScript code, you are by definition dealing with a string. (More here.) If you want to deal with the object that the JSON describes, parse it.
Here's an example of parsing it and getting the value of the extension_id property from it:
const parsed = JSON.parse(frames[1]._name);
console.log(parsed.extension_id); // The ID
I am reading a file which comes in as an attachment like follows
let content = fs.readFileSync(attachmentNames[index], {encoding: 'utf8'});
When I inspect content, it looks ok, I see file contents but when I try to assign it to some other variable
attachmentXML = builder.create('ATTACHMENT','','',{headless:true})
.ele('FILECONTENT',content).up()
I get the following error
Error: Invalid character in string: PK
There are a couple of rectangular boxes (special characters) after PK in the above message which are not getting displayed.
builder here refers to an instance of the xmlbuilder https://www.npmjs.com/package/xmlbuilder node module.
I fixed this by enclosing the string inside a JS escape() method
I use YamlDotnet to parse a yaml stream to a dictionary of string object via the YamlStream.
The YamlMappingType, YamlSequenceNode and YamlScalarNode are used in order to convert the value to a dictionary, a list or a string.
But I need to get a real boolean value instead of the string equivalent, and for that I use
bool.TryParse(value.ToString(), out valueBool)
value veing a YamlNode.
Is there a better way to do that?
Perhaps another child type of YamlNode?
EDIT:
I don't know the content of the YAML file, I just want to get a dictionary with his values.
Instead of doing the parsing manually, you should use the Deserializer class, which will convert a YAML document into an object graph.
var deserializer = new Deserializer();
var parsed = deserializer.Deserialize<...>(input);
You can see a working example here
How can I reliably get the 64bit data from an XML file to a byte[] and then compare that with a string? The following code fails as it seems the whitespace is causing the assert to fail. The goal is for the assert to pass.
Note that it is important that we have it in the form of byte[] at somepoint, but not that the comparison be via strings

byte[] byteData = document.Contents.text()
assert 'VGVzdGluZyBURSBzZXNzaW9uIGNvbnRhaW5pbmcgQ29tcGxldGUgUGVyc29uIEEgYW5kIENvbXBs'+
'ZXRlIEVxdWlwbWVudCBCLg0KDQpUZXN0IFRlc3QNCg0KUmVmZXJlbmNlcyBDb21wbGV0ZSBQbGFj'+
'ZSBB' == new String(byteData)
Base 64 data is a special encoding of text to ASCII to be URL friendly (historically)
EDIT thanks to comment below, actually base64 was to encode data to send via for email
to extract text from your data, do this:
new String(
'VGVzdGluZyBURSBzZXNzaW9uIGNvbnRhaW5pbmcgQ29tcGxldGUgUGVyc29uIEEgYW5kIENvbXBsZXRlIEVxdWlwbWVudCBCLg0KDQpUZXN0IFRlc3QNCg0KUmVmZXJlbmNlcyBDb21wbGV0ZSBQbGFjZSBB')
.decodeBase64()
)
result starts with 'ession containing Complete Person A and Complete Equipment B.'
