Question

我需要发出发布请求，以便在发布请求的正文中发送需要用utf-8编码的字典，我在下面尝试了此方法，但它给出了一个错误：

  let DicObject: NSMutableDictionary = NSMutableDictionary()
        DicObject.setValue("cf", forKey: "a")
        DicObject.setValue("", forKey: "scs")
        DicObject.setValue("Uploads/" + nameOfFile, forKey:"p")

当我尝试制作

 request.httpMethod = "POST"
      //  request.httpBody = jsonObject as Data
        request.addValue("Content-Type", forHTTPHeaderField: "application/x-www-form-urlencoded; charset=utf-8")

它不起作用，有人知道如何将jsonObject编码转换为utf-8

谢谢。

Answer 1

您可以使用jsonObject将data转换为JSONSerialization，然后将data转换为string，最后将string转换为data

if let data = try? JSONSerialization.data(withJSONObject: jsonObject, options: .prettyPrinted),
   let jsonString = String(data: data, encoding: .utf8) {
       request.httpBody = jsonString.data(using: .utf8)
}

Answer 2

尝试一下，

 let jsonData: NSData

 do {
        jsonData = try JSONSerialization.data(withJSONObject: DicObject, options: JSONSerialization.WritingOptions()) as NSData
        let jsonString = NSString(data: jsonData as Data, encoding: String.Encoding.utf8.rawValue)! as String
        print("json string = \(jsonString)")
        print("json jsonData = \(jsonData)")

   } catch _ {
           print ("JSON Failure")
   }

谢谢！
