数据字符串为JSON Swift3

我在swift3中使用URLRequest。 为了使用休息服务,我需要在URLResquest中添加一个正文,为此我使用这个字符串:

 public func jsonPush() -> String {
    let date = NSDate().addingTimeInterval(60)

    let text: String =
        "{" +
            "\"action\": {" +
            "  \"content\": {" +
            "  \"default\": \"VIP\"" +
            "}," +
            "\"@type\": \"SendLocalMessageAction\"," +
            " \"bgAlert\": { " +
            " }, " +
            " \"contentType\": \"text\\/plain\"" +
            "}," +
            "\"draft\": false, " +
            "\"trigger\": { " +
            "\"time\": "+"\(date.timeIntervalSince1970 * 1000)"+", " +
            "\"@type\": \"TimeTrigger\" " +
            "}, " +
            "\"config\": { " +
            "\"name\": \"Llego el cliente VIP Daniel\" " +
            "}, " +
            "\"audience\": { " +
            "\"type\": \"UserIds\", " +
            "\"ids\": [ " +
            "\"DGHCiwUTbDYnmSOOe7CwKKEB5SA2\", " +
            "\"FgLN69yCR1RzKY23fFdYhTD2HZg1\" " +
            "] " +
            " } " +
    "} "
    print("El json es:\(text) como valor final")
        return text
}

但是当我尝试发送数据时

 var request = URLRequest(url: URL(string: uriNotifications + appId)!)
        request.httpMethod = "POST"
        request.addValue(autenticacion, forHTTPHeaderField: "Authorization")
        request.addValue("application/json", forHTTPHeaderField: "Content-Type")
        let session = URLSession.shared
               request.httpBody=jsonPush() as? Data
        session.dataTask(with: request) { data, response, error in
            print("Entered the completionHandler")
                       if(error != nil) {
                print("error")
                return
            }
            do {
                let json = try JSONSerialization.jsonObject(with: data!, options: .allowFragments)
                //  let posts = json["posts"] as? [[String: Any]] ?? []
                print("Cantidad")
                print(json)
            } catch let parseError {
                print("parsing error: \(parseError)")
                let responseString = String(data: data!, encoding: .utf8)
                print("raw response: \(responseString)")
            }

回复是:

  

{       error =“错误请求”;       “error_description”=“无法解析JSON:由于输入结束而没有要映射的内容”; }

但如果我尝试输出:

  

{“action”:{“content”:{“default”:“VIP”},“@ type”:   “SendLocalMessageAction”,“bgAlert”:{},“contentType”:   “text / plain”},“draft”:false,“trigger”:{“time”:1497373512981.26,   “@type”:“TimeTrigger”},“config”:{“name”:“Llego el cliente VIP   Daniel“},”观众“:{”type“:”UserIds“,”ids“:[   “DGHCiwUTbDYnmSOOe7CwKKEB5SA2”,“FgLN69yCR1RzKY23fFdYhTD2HZg1”]}}

反响很好:

问题很可能是request.httpBody=jsonPush() as? Data方法问题jsonPush返回String,您直接将其转换为Data,而不是使用data(using:) request.httpBody = jsonPush().data(using: .utf8) 1}}用字符串来获取数据。
