Question

现在，我已经通过下面给出的代码将一个图像上传到服务器端脚本的服务器上。现在我有一个UIImage数组，我想知道如何使用UIImageJPEGRepresentation(myImageView.image!, 0.1)在UIImageView数组中发布所有图像？

func uploadImage()
{
    let postPictureUrl = NSURL(string: "http://www.23look.com/merchant/verify")
    let request = NSMutableURLRequest(URL: postPictureUrl!)
    request.HTTPMethod="POST"

    let param=[
        "mer_name" : shopNameUITF.text!,
        "mer_tel" : shopTelephoneUITF.text!,
        "mer_address" : shopAddressUITF.text!,
        "lat" : "39.6892",
        "lng" : "115.9239",
        "token": KeychainWrapper.stringForKey("tokenValue")!,
        "mer_type": "smalll"
    ]

    let abc =  KeychainWrapper.stringForKey("tokenValue")!

    let boundary = generateBoundaryString()

    request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")

    let imageData = UIImageJPEGRepresentation(myImageView.image!, 0.1)

    if imageData==nil { print("image data is nil"); return }

    request.HTTPBody = createBodyWithParameters(param, filePathKey: "mer_license", imageDataKey: imageData!, boundary: boundary)

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

        if error != nil {
            print("error=\(error)")
            return
        }

        //You can print out response object
        print("***** response = \(response)")

        // Print out reponse body
        let responseString = NSString(data: data!, encoding: NSUTF8StringEncoding)
        print("**** response data = \(responseString!)")

        do {

            let json = try NSJSONSerialization.JSONObjectWithData(data!, options: .MutableContainers) as? NSDictionary

            dispatch_async(dispatch_get_main_queue(), {
                print(NSString(data: data!, encoding:NSUTF8StringEncoding)!)
                print(json)
            })

        } catch let err {
            print(err)
        }
    }
    task.resume()
}

func generateBoundaryString() -> String {
    return "Boundary-\(NSUUID().UUIDString)"
}

func createBodyWithParameters(parameters:[String:String]?, filePathKey: String?, imageDataKey:NSData, boundary: String) -> NSData {

    var body=NSMutableData()

    if parameters != nil {
        for(key, value) in parameters! {
            body.appendString("--\(boundary)\r\n")
            body.appendString("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n")
            body.appendString("\(value)\r\n")
        }
    }

    let filename = "user-profile.jpg"
    let mimetype = "image/jpg"

    body.appendString("--\(boundary)\r\n")
    body.appendString("Content-Disposition: form-data; name=\"\(filePathKey!)\"; filename=\"\(filename)\"\r\n")
    body.appendString("Content Type: \(mimetype)\r\n\r\n")
    body.appendData(imageDataKey)
    body.appendString("\r\n")

    body.appendString("-\(boundary)-\r\n")

    return body
}

需要以下参数：

mer_name - String

mer_tel - String

mer_address - string

lng - string

lat - string

mer_licence - 文件类型（这是我的图片将被上传的地方）

token - string

mer_type - string

您应该在createBodyWithParameters中进行更改，如下所示.........

当你有多张图片时......

return this.waitFor({
    pollingInterval : 100,
    viewName : "sap.ui.commons.MessageBox",
    check : function () {
        return !!sap.ui.test.Opa5.getJQuery()(".MessageBox").length;
    },
    success : function () {
        ok(true, "I see a confirm popup");
    },
    errorMessage : "Did not find confirmation popup"

});

    doOnMain {
        Loading.sharedInstance.startloading()
    }
    let url = NSURL(string:"URL")
    let request = NSMutableURLRequest(url: url! as URL)
    request.httpMethod = "POST"
    let headers = ["Accept-Language": "en"]
    request.allHTTPHeaderFields = headers
    let boundary = generateBoundaryString()
    //define the multipart request type
    request.setValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")

    if (imgRefund.image == nil){
        return
    }

    // First Image
    let image_data = imgRefund.image!.pngData()
    if(image_data == nil){
        return
    }

    // Second Image

    let image_data1 = imgRefund1.image!.pngData()
    if(image_data1 == nil){
        return
    }

    let body = NSMutableData()
    let fname = "filename"
    let fname1 = "filename1"
    let mimetype = "image/png"

    let parameters = ["key":"value","key":"value"]
    if parameters != nil {
        for (key, value) in parameters {
            body.append("--\(boundary)\r\n".data(using: String.Encoding.utf8)!)
            body.append("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n".data(using: String.Encoding.utf8)!)
            body.append("\(value)\r\n".data(using: String.Encoding.utf8)!)
        }
    }

    // First Image

    body.append("--\(boundary)\r\n".data(using: String.Encoding.utf8)!)
    body.append("Content-Disposition:form-data; name=\"test\"\r\n\r\n".data(using: String.Encoding.utf8)!)
    body.append("hi\r\n".data(using: String.Encoding.utf8)!)
    body.append("--\(boundary)\r\n".data(using: String.Encoding.utf8)!)
    body.append("Content-Disposition:form-data; name=\"parameter\"; filename=\"\(fname)\"\r\n".data(using: String.Encoding.utf8)!) // paramenter name
    body.append("Content-Type: \(mimetype)\r\n\r\n".data(using: String.Encoding.utf8)!)
    body.append(image_data!)
    body.append("\r\n".data(using: String.Encoding.utf8)!)
    body.append("--\(boundary)--\r\n".data(using: String.Encoding.utf8)!)


    // Second Image
    body.append("--\(boundary)\r\n".data(using: String.Encoding.utf8)!)
    body.append("Content-Disposition:form-data; name=\"test\"\r\n\r\n".data(using: String.Encoding.utf8)!)
    body.append("hi\r\n".data(using: String.Encoding.utf8)!)
    body.append("--\(boundary)\r\n".data(using: String.Encoding.utf8)!)
    body.append("Content-Disposition:form-data; name=\"parameter1\"; filename=\"\(fname1)\"\r\n".data(using: String.Encoding.utf8)!) // paramenter name 1
    body.append("Content-Type: \(mimetype)\r\n\r\n".data(using: String.Encoding.utf8)!)
    body.append(image_data1!)
    body.append("\r\n".data(using: String.Encoding.utf8)!)
    body.append("--\(boundary)--\r\n".data(using: String.Encoding.utf8)!)





    request.httpBody = body as Data

    let session = URLSession.shared
    let task = session.dataTask(with: request as URLRequest) {
        (
        data, response, error) in
        guard let _:NSData = data! as NSData, let _:URLResponse = response, error == nil else {
            print("error")
            return
        }
        let responseString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
        print("****** response data = \(responseString!)")
        do {
            let json = try JSONSerialization.jsonObject(with: data!, options: []) as? NSDictionary
            print("****** response json = \(json!)")

            if(json?.value(forKey: "status") as! Int == 200){
                print(json)
            }
            else{

            }
        }catch{
            print(error)
        }
    }
    task.resume()

 func generateBoundaryString() -> String {
    return "Boundary-\(NSUUID().uuidString)"
}

在Swift中使用其他参数上传多个图像
