如何int值添加到Alamofire參數上傳

Question

我想Int值添加到multipartFormData：

Alamofire.upload(.POST, 
       url, 
       headers: headers, 
       multipartFormData: { multipartFormData in 
        //add some jpg image 
        //add other vaues: 
        for (key, value) in parameters { 
         if value is String { 
          multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key) 
         } else if value is Int { 
          let convertedValueNumber: NSNumber = NSNumber(int: value.intValue) 
          let data = NSKeyedArchiver.archivedDataWithRootObject(convertedValueNumber) 
          multipartFormData.appendBodyPart(data: data, name: key) 
         } 
        } 

    }, encodingCompletion: { encodingResult in 
     //some processing 
}) 

但是，我不送Int值服務器返回錯誤。如何將Int值添加到參數中？

Answer 1

NSKeyedArchiver非常好奇。通常你只要發送字符串表示，例如：

Alamofire.upload(.POST, URL, headers: headers, multipartFormData: { multipartFormData in 
    //add some jpg image 
    //add other values: 
    for (key, value) in parameters { 
     if value is String { 
      multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key) 
     } else if value is Int { 
      multipartFormData.appendBodyPart(data: "\(value)".dataUsingEncoding(NSUTF8StringEncoding)!, name: key) 
     } 
    } 
}, encodingCompletion: { encodingResult in 
    //some processing 
}) 

甚至更​​簡單，因爲串插既String和Int工作：

Alamofire.upload(.POST, URL, headers: headers, multipartFormData: { multipartFormData in 
    //add some jpg image 
    //add other values: 
    for (key, value) in parameters { 
     if value is String || value is Int { 
      multipartFormData.appendBodyPart(data: "\(value)".dataUsingEncoding(NSUTF8StringEncoding)!, name: key) 
     } 
    } 
}, encodingCompletion: { encodingResult in 
    //some processing 
}) 

或者，在Alamofire 4斯威夫特3：

Alamofire.upload(multipartFormData: { multipartFormData in 
    //add some jpg image 
    //add other values: 
    for (key, value) in parameters { 
     if value is String || value is Int { 
      multipartFormData.append("\(value)".data(using: .utf8)!, withName: key) 
     } 
    } 
}, to: url, method: .post, headers: headers, encodingCompletion: { encodingResult in 
    //some processing 
})
