SWIFT翻译器应用程序 [英] SWIFT Translator App

问题描述

我使用Yandex API创建翻译器. 我使用此功能:

I create translator using Yandex api. I use this function:

func getTranslate(text: String, lang: String, completion: @escaping (Translation?) -> Void) {
    guard let url = URL(string: translateUrl + "?key=\(key)&text=\(text)&lang=\(lang)&format=plain&options=1") else { return }
    var request = URLRequest(url: url)
    request.httpMethod = "POST"

    URLSession.shared.dataTask(with: request) { (data, response, error) in
        if let error = error {
            print(error.localizedDescription)
            completion(nil)
            return
        }

        guard let data = data else {
            completion(nil)
            return
        }

        do {
            let translation = try JSONDecoder().decode(Translation.self, from: data)
            completion(translation)
        } catch {
            print(error)
            completion(nil)
        }
        }.resume()
}

但是，如果我在文本"中输入更多内容，则不会进行一个单词的翻译.

But if I enter in "Text" more one word translation is not carried out.

API文档说:

对于源代码，请确保使用URL编码."

"For the source code, be sure to use URL-encoding."

我怀疑我的问题与我只使用文本而不以任何方式编码的事实有关. 该问题如何解决?

I suspect that my problem is related to the fact that I just use the text, not coding it in any way. How can this problem be solved?

推荐答案

在这种情况下，强烈建议使用URLComponents和URLQueryItem，它隐式处理URL编码

In this case it's highly recommended to use URLComponents and URLQueryItem, it handles URL encoding implicitly

guard var components = URLComponents(string: translateUrl) else { return }
components.queryItems = [URLQueryItem(name: "key", value: key),
                         URLQueryItem(name: "text", value: text),
                         URLQueryItem(name: "lang", value: lang),
                         URLQueryItem(name: "format", value: "plain"),
                         URLQueryItem(name: "options", value: String(1))]
var request = URLRequest(url: components.url!)
