如何使用SwiftyJson在下面的json文件中使用键“text”提取所有值?这是来自Microsoft认知服务文本识别的响应。

json文件要大得多,并且有很多值具有不同深度的关键“文本”,我不知道如何循环整个Json体!谢谢你的帮助
将所有对象整合到Codable
,然后在实例化实例后,根据需要进行挖掘,例如使用TextDto
包装类:
class TextDto: Codable {
let language: String
let textAngle: Int
let orientation: String
let regions: [Region]
init(language: String, textAngle: Int, orientation: String, regions: [Region]) {
self.language = language
self.textAngle = textAngle
self.orientation = orientation
self.regions = regions
}
}
class Region: Codable {
let boundingBox: String
let lines: [Line]
init(boundingBox: String, lines: [Line]) {
self.boundingBox = boundingBox
self.lines = lines
}
}
class Line: Codable {
let boundingBox: String
let words: [Word]
init(boundingBox: String, words: [Word]) {
self.boundingBox = boundingBox
self.words = words
}
}
class Word: Codable {
let boundingBox, text: String
init(boundingBox: String, text: String) {
self.boundingBox = boundingBox
self.text = text
}
}
一旦你从api获得了TextDto
,你可以用你认为合适的lines
闭合或words
循环遍历所有.forEach {}
和for...in
