你好，我是iOS开发的新手，正在尝试在我的应用程序中实现谷歌翻译API。我从GitHub上找到了一些示例代码https://github.com/prine/ROGoogleTranslate。我下载了示例代码，并按照提供的说明从谷歌云翻译获取了API密钥并将其放置在代码中，但是代码无法正常工作。我查看了GitHub网站上的评论，并发现它已经为其他开发人员工作过。我真的不知道我在代码中做错了什么。
ROGoogleTranslateParams.swift
import Foundation
public struct ROGoogleTranslateParams {
public init() {
}
public init(source:String, target:String, text:String) {
self.source = source
self.target = target
self.text = text
}
public var source = "de"
public var target = "en"
public var text = "Hallo"
}
/// Offers easier access to the Google Translate API
open class ROGoogleTranslate {
/// Store here the Google Translate API Key
public var apiKey = "YOUR_API_KEY"
///
/// Initial constructor
///
public init() {
}
///
/// Translate a phrase from one language into another
///
/// - parameter params: ROGoogleTranslate Struct contains all the needed parameters to translate with the Google Translate API
/// - parameter callback: The translated string will be returned in the callback
///
open func translate(params:ROGoogleTranslateParams, callback:@escaping (_ translatedText:String) -> ()) {
guard apiKey != "" else {
print("Warning: You should set the api key before calling the translate method.")
return
}
if let urlEncodedText = params.text.addingPercentEncoding(withAllowedCharacters: .urlHostAllowed) {
if let url = URL(string: "https://translation.googleapis.com/language/translate/v2?key=\(self.apiKey)&q=\(urlEncodedText)&source=\(params.source)&target=\(params.target)&format=text") {
let httprequest = URLSession.shared.dataTask(with: url, completionHandler: { (data, response, error) in
guard error == nil else {
print("Something went wrong: \(error?.localizedDescription)")
return
}
if let httpResponse = response as? HTTPURLResponse {
guard httpResponse.statusCode == 200 else {
if let data = data {
print("Response [\(httpResponse.statusCode)] - \(data)")
}
return
}
do {
// Pyramid of optional json retrieving. I know with SwiftyJSON it would be easier, but I didn't want to add an external library
if let data = data {
if let json = try JSONSerialization.jsonObject(with: data, options:JSONSerialization.ReadingOptions.mutableContainers) as? NSDictionary {
if let jsonData = json["data"] as? [String : Any] {
if let translations = jsonData["translations"] as? [NSDictionary] {
if let translation = translations.first as? [String : Any] {
if let translatedText = translation["translatedText"] as? String {
callback(translatedText)
}
}
}
}
}
}
} catch {
print("Serialization failed: \(error.localizedDescription)")
}
}
})
httprequest.resume()
}
}
}
}
ViewController.swift
import UIKit
class ViewController: UIViewController {
@IBOutlet var text:UITextField!
@IBOutlet var fromLanguage:UITextField!
@IBOutlet var toLanguage:UITextField!
@IBOutlet var translation:UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func translate(_ sender: UIButton) {
let translator = ROGoogleTranslate()
translator.apiKey = "YOUR_API_KEY" // Add your API Key here
var params = ROGoogleTranslateParams()
params.source = fromLanguage.text ?? "de"
params.target = toLanguage.text ?? "en"
params.text = text.text ?? "Hallo"
translator.translate(params: params) { (result) in
DispatchQueue.main.async {
self.translation.text = "\(result)"
}
}
}
}
这些类被使用。 当我按下“翻译”按钮时，我得到的结果如下： 响应[403] - 355字节
感谢您的帮助。代码可从提供的网址下载。 谢谢。
