decode

问题 I have faced a problem, unfortunately, I have not found a correct solution: I need to decode url-slice that is encoded with windows-1251 (cp1251). I know there are theese methods - decodeURI() and decodeURIComponent() , but they work for UTF-8 only (as I have understood). A solution that I found uses deprecated methods escape() and unescape(). For example, there is sequence: %EF%F0%EE%E3%F0%E0%EC%EC%E8%F0%EE%E2%E0%ED%E8%E5 (программирование) The methods decodeURI() and decodeURIComponent()

问题 My json looks like this: {"name": "providerWithVal", "value": "example"} or like this: {"name": "provider2"} or {"name": "provider3"} My Elm union type is defined like so: type Provider = ProviderWithVal String | Provider2 | Provider3 I can write a decoder for a union type without data attached. But ProviderWithVal takes a string and I'm not sure how to make it all work. This is what I have so far: import Json.Decode as D providerDecoder : D.Decoder Provider providerDecoder = D.field "name" D

问题 I'm working on a CMS system and I want to add a feature to protect user's data. Of course passwords are hashed and could only be decoded using brute forcing. But now it's about the rest of the data, for example their mail address. I would like to have a function which encodes a mail address when a user registers which could be decoded each time a mail should be send. Now the problem with hashing is that you can't easily convert it back (I think), at least with md5 and sh1 and similar

问题 I tried to convert byte[] to string as follows: Map<String, String> biomap = new HashMap<String, String>(); biomap.put("L1", new String(Lf1, "ISO-8859-1")); where Lf1 is byte[] array and then i convert this string to byte[]: problem is, when i convert byte array to string it comes like: FMR F P�d@� �0d@r (@� ......... etc and String SF1 = biomap.get("L1"); byte[] storedL1 = SF1.getBytes("ISO-8859-1") and when i convert back it to byte array and compare both arrays, it return false. I mean

问题 I have a string which might include br or span.../span tags or other HTML characters/entities. I want a robust way of stripping all that and getting the remaining UTF-8 characters. This be should be cross-platform, ideally. Something like this would be ideal: http://snipplr.com/view/15261/python-decode-and-strip-html-entites-to-unicode/ but that also removes the tags. 回答1: Just how stringent are your requirements? A simple two-state FSA ought to do. Start in the READCHAR state. Whenever you

问题 Is there any PHP function that encodes a string to a int value, which later I can decode it back to a string without any key? 回答1: Sure, you can convert strings to numbers and vice versa. Consider: $a = "" + 1 gettype($a) // integer $b = "$a" gettype($b) // string You can also do type casting with settype(). If I misunderstood you and you want to encode arbitrary strings, consider using base64_encode() and bas64_decode(). If you want to convert the base 64 string representation to a base 10

问题 I got a url encode string %B9q while I use C# code: string res = HttpUtility.UrlDecode("%B9q", Encoding.GetEncoding("Big5")); It outputs as 電，which is the correct answer that I want But when I use Java decode function: String res = URLDecoder.decode("%B9q", "Big5"); Then I got the output ?q Does anyone knows how it happens and how should I solve it? Thanks for any suggestions and helps! 回答1: As far as I can tell from the relevant spec, it looks like Java's way of handling things is correct.

问题 private func createWeatherObjectWith(json: Data, x:Any.Type ,completion: @escaping (_ data: Any?, _ error: Error?) -> Void) { do { let decoder = JSONDecoder() decoder.keyDecodingStrategy = .convertFromSnakeCase let weather = try decoder.decode(x.self, from: json) return completion(weather, nil) } catch let error { print("Error creating current weather from JSON because: \(error.localizedDescription)") return completion(nil, error) } } Here I write above code to decode Json string to class

问题 I am attempting to match a string I know to a web page title in php. I have the following string: ℛobinhood I have a page title that looks like this: ℛobinhood but is actually encoded like this if I look at the <title> element: ℛobinhood I'm not sure how to compare these two strings. How do I either convert the ℛ to ℛ or the other way so that I can do a proper comparison? 回答1: You can use htmlentites ( http://php.net/manual/en/function.htmlentities.php ) to convert to the entity version. 回答2:

问题 Could anyone help me with writing case statements in Informatica PowerCenter Designer? I am fairly new to Informatica, and based on my limited experience I feel case statements aren't supported. There is a decode function with similar functionality, but I am unable to find any good examples on the syntax. I would really appreciate if anyone could give me some specific examples on how to use case statements/decode function in Informatica. Thanks much for your help! 回答1: You're right - there is
