錯誤：在Swift上發佈時

我從後端開發人員處獲得了下面的post服務，現在我試圖在swift上實現它。錯誤：在Swift上發佈時

<form role="form" method="post" action=「order_post.asp" id="frmBack"> 
    <input type="hidden" name="product_id" value="297"> 
    <input type="hidden" name="order_no" value="010223005373"> 
    <input type="hidden" name=「city」 value=「Paris」> 
    <input type="hidden" name=「county」 value=「La Fayette」> 
    <input type="hidden" name="price" value="143"> 
    <input type="hidden" name=「receiver_name」 value=「Jane Doe」> 
    <input type="hidden" name=「sender_name」 value=「John Doe「> 
    <input type="submit" id="submit_back_handle">

我已經寫了下面的代碼，但它沒有工作，叫我填寫表格上的所有字段。有人可以告訴我我錯過了什麼嗎？

func post() { 

    let params = [ 
     「product_id": "297", 
     「order_no": "010215135311", 
     「city」: 「Paris」, 
     「county」: 「La Fayette「, 
     "price": "143", 
     "receiver_name": 「Jane Doe「, 
     "sender_name": 「John Doe」, 
     ] as Dictionary <String, String> 

    let request = NSMutableURLRequest(URL: NSURL(string: "http://webservis.mydomain.com/order_post.asp")!) 

    let session = NSURLSession.sharedSession() 
    request.HTTPMethod = "POST" 
    request.addValue("application/json", forHTTPHeaderField: "Content-Type") 
    request.addValue("application/json", forHTTPHeaderField: "Accept") 

    request.HTTPBody = try! NSJSONSerialization.dataWithJSONObject(params, options: []) 

    let task = session.dataTaskWithRequest(request) { data, response, error in 


     guard data != nil else { 
      print("no data found: \(error)") 
      return 
     } 

     do { 
      if let json = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? NSDictionary { 
       let success = json["success"] as? Int         // Okay, the `json` is here, let's get the value for 'success' out of it 
       print("Success: \(success)") 
      } else { 

       let cfEnc = CFStringEncodings.ISOLatin5 
       let enc = CFStringConvertEncodingToNSStringEncoding(CFStringEncoding(cfEnc.rawValue)) 

       let jsonStr = NSString(data: data!, encoding: enc) // No error thrown, but not NSDictionary 
       print("Error could not parse JSON: \(jsonStr)") 
      } 
     } catch let parseError { 
      print(parseError)               // Log the error thrown by `JSONObjectWithData` 

      let cfEnc = CFStringEncodings.ISOLatin5 
      let enc = CFStringConvertEncodingToNSStringEncoding(CFStringEncoding(cfEnc.rawValue)) 

      let jsonStr = NSString(data: data!, encoding: enc) 
      print("Error could not parse JSON: '\(jsonStr)'") 
     } 
    } 

    task.resume() 

}

什麼沒有準確地工作？ – Qbyte

我得到以下錯誤; {「status」：「0」，「msg」：「請填寫空值！」，「name」：「Post Order」}。即使當我嘗試郵遞員時，我也有同樣的錯誤 – mehmeet43

你從哪裏得到錯誤？ – Qbyte

我的代碼開始我改變了字典後下方jsonString和request.HTTPBody方法有關jsonString工作。

let form1 = "product_id=297&order_no=010215135311&city=Paris&…」 

request.HTTPBody = form1.dataUsingEncoding(NSUTF8StringEncoding)

我想這是編碼問題，但我不確定。
