关于阿里云API的Swift语言桥接，首先要进行APPCODE的获取，这里就不多废话了，阿里云官网有教程。
阿里云控制台；https://home.console.aliyun.com/new#/
接下来直接上代码：
funcpostData(_text:String,_completionHandler:@escaping(_result: [String:Any]) ->Void) {
let host = "http://gjccq.market.alicloudapi.com/rest/160601/text_analysis/key_words_extraction.json"
varrequest =URLRequest(url:URL(string: host)!)
request.httpMethod="POST"
//请求添加头Header
request.addValue("APPCODE 你的APPCODE", forHTTPHeaderField:"Authorization")
//添加Json返回格式
request.addValue("application/json; charset=UTF-8", forHTTPHeaderField: "Content-Type")
request.cachePolicy = URLRequest.CachePolicy(rawValue: 1)!
request.timeoutInterval = 5
let body = "{\"inputs\":[{\"text\":{\"dataType\":50,\"dataValue\":\"\(text)\"},\"config\":{\"dataType\":50,\"dataValue\":\"{\\\"topN\\\":3,\\\"similarityType\\\":\\\"lcs\\\",\\\"delimiter\\\":\\\"。！？\\\"}\"}}]}"
print(#line,body)
request.httpBody= body.data(using:String.Encoding.utf8)!
URLSession.shared.dataTask(with: request) { data, response, errorin
if error == nil && data != nil{
do{
letdic =tryJSONSerialization.jsonObject(with: data!, options: [])as! [String:Any]
letarray = dic["outputs"]as! [Dictionary]
completionHandler(array[0])
}catch {
print(#line, error)
}
return
}
}.resume() //[task resume];
}
这个是封装好的API桥接方法，接下来是调用：
postData("你要分析的文本") { (result) in
DispatchQueue.main.async(execute: {() -> Void in
print(#line, result)
let outputValue = result["outputValue"] as! [String:Any]
let dataValue = outputValue["dataValue"] as! String
var resultDic: [String: Any]? = nil
if let anEncoding = dataValue.data(using: .utf8) {
resultDic = try! JSONSerialization.jsonObject(with: anEncoding, options: []) as? [String: Any]
}
let wordsweight = resultDic!["words weight"] as! [Any]
var myArray = [String]()
for i in 0..<wordsweight.count {
let wordArray = wordsweight[i] as! [String : Any]
let word = wordArray["word"] as! String
myArray.append(word)
print(#line,myArray)
}
})
}
最终打印结果就是我们拿到的关键字
