入力メッセージと投稿データを含むJSON投稿

Question

メイク、モデル、カラーオプションなどを取得するために、特定のVINでこのAPIに投稿しようとしています...コードを実行すると、次のデータがXCodeのコンソール：

responseString = Optional("  {  \"decoder_messages\" : {  \"service_provider\" : \"DataOne Software, Inc.\",  \"decoder_version\" : \"7.0.1\",  \"decoder_errors\" : [  {   \"error_code\" : \"IQ\",   \"error_message\" : \"Invalid query. Query must be properly formatted JSON.\"   }    ]  },   \"query_responses\" : {   }  }  ") 

私は私のgetJSONInput（）関数であるかもしれないエラーを推測しているが、私は同じ結果にさまざまな方法を試してみました。何か助けてくれてありがとう、私はこれをぶち抜いて、あらゆる種類のドキュメントを読んで、サンプルコードで試してみました。私もAlamofireでこれを試しましたが、パラメータとしてpostStringを渡す際の問題がありましたので、私はこのアプローチを試みると思っていました。

@IBAction func postButtonPressed(_ sender: AnyObject) { 
     getJSONInput() 
     postJSON() 
} 


func postJSON(){ 


    var request = URLRequest(url: URL(string: url)!) 
    request.httpMethod = "POST" 
    let postString = "client_id=xxx&authorization_code=xxx&decoder_query=\(JSONInput)" 
    request.httpBody = postString.data(using: .utf8) 
    let task = URLSession.shared.dataTask(with: request) { data, response, error in 
     guard let data = data, error == nil else { 
      print("error=(error)") 
      return 
     } 

     if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { 
      print("statusCode should be 200, but is \(httpStatus.statusCode)") 
      print("response = \(response)") 

     } 

     let responseString = String(data: data, encoding: .utf8) 
     print("responseString = \(responseString)") 
    } 
    task.resume() 
}
