req.getParameterMap returns an immutable map which cannot be modified. You need to create a new map, putAll from the parameter map and remove the required key you do not want. def reqParams = [:] << req.getParameterMap() reqParams.remove(‘blah’) You have your new map as reqParams (without the undesired key value pair) and the original parameter map.
Chen, I think your answer is correct. Some further background that might be helpful: In JavaScript, which was the original context for JSON, an object is like a hash map of strings to values, where some values are data, others are functions. You can think of each name-value pair as a property. But JavaScript doesn’t … Read more
Using additionalPropertiesis the proper way to describe hashmap with OpenAPI (fka. Swagger) Specification but Swagger UI do not render them for now. The issue is tracked here https://github.com/swagger-api/swagger-ui/issues/1248 Meanwhile you can use this trick: define a non required property (defaultin the example below) of the same type of the map’s objects and give some hint … Read more
When you define a Dictionary in Swift you have to give key and value types as well. Something like: var jsonResult = responseObject as Dictionary<String, AnyObject> If the cast fails, however, you’ll get a runtime error — you’re better off with something like: if let jsonResult = responseObject as? Dictionary<String, AnyObject> { // do whatever … Read more
Yes, you can create a map with a single statement (called a composite literal in the spec): var keys = map[int]string{ 1: “aa”, 2: “ab”, 3: “ac”, 4: “ba”, 5: “bb”, 6: “bc”, 7: “ca”, 8: “cb”, 9: “cc”, } Or, if you are inside of a function, you can use a short variable declaration: … Read more
You don’t need reflect here. Try: v, ok := in.(map[string]*Book) if !ok { // Can’t assert, handle error. } for _, s := range v { fmt.Printf(“Value: %v\n”, s) } Same goes for the rest of your function. It looks like you’re using reflection when you would be better served by a type switch. Alternatively, … Read more
The Sentiment Lexicon, at the University of Pittsburgh might be what you are after. It’s a lexicon of about 8,000 words with positive/neutral/negative sentiment. It’s described in more detail in this paper and released under the GPL.
The data type here was the key. mdi was not actually a map, but an interface{}, which could be anything – a map, a string, an int. You need to assert it to a map with expected key/value types first, or do the awkward case switch outlined in JSON and Go. mdi, err := page.Metadata() … Read more
Since v0.15 we have Map.from_struct/1 which does exactly this. defmodule User do defstruct [:name] end Map.from_struct(%User{name: “valim”}) #=> %{name: “valim”}
key: is parsed as null – %YAML 1.1 — !!map { ? !!str “key” : !!null “null”, } The correct answer is: key: “”
