如何在Swift中使用Alamofire上传带参数的图像

Question

我正在用Swift开发一个iPhone应用程序。我正在使用Alamofire框架来处理http请求。我将alamofire.request用于POST,GET等，如下所示：

Alamofire.request(.POST, myURL , parameters: ["a": "1", "b" : "2" ])
        .response { (request, response, data, error) in
}  

我使用alamofire.upload将图像上载到服务器：

Alamofire.upload(.POST, uploadURL , fileURL)

谁能帮我解决这个问题？

谢谢！：）

您可以使用以下代码的Alamofire 3.0+

func uploadImageAndData(){
    //parameters
    let gender    = "M"
    let firstName = "firstName"
    let lastName  = "lastName"
    let dob       = "11-Jan-2000"
    let aboutme   = "aboutme"
    let token     = "token"

    var parameters = [String:AnyObject]()
    parameters = ["gender":gender,
                  "firstName":firstName,
                  "dob":dob,
                  "aboutme":about,
                  "token":token,
                  "lastName":lastName]

    let URL = "http://yourserviceurl/"
    let image = UIImage(named: "image.png")

    Alamofire.upload(.POST, URL, multipartFormData: {
        multipartFormData in

        if let imageData = UIImageJPEGRepresentation(image, 0.6) {
            multipartFormData.appendBodyPart(data: imageData, name: "image", fileName: "file.png", mimeType: "image/png")
        }

        for (key, value) in parameters {
            multipartFormData.appendBodyPart(data: value.dataUsingEncoding(NSUTF8StringEncoding)!, name: key)
        }
    }, encodingCompletion: {
        encodingResult in

        switch encodingResult {
        case .Success(let upload, _, _):
            print("s")
            upload.responseJSON { 
                response in
                print(response.request)  // original URL request
                print(response.response) // URL response
                print(response.data)     // server data
                print(response.result)   // result of response serialization

                if let JSON = response.result.value {
                    print("JSON: \(JSON)")
                }
            }
        case .Failure(let encodingError):
            print(encodingError)
        }
    })
}
