我在使用Alamofire中的多部分在多个图像阵列中上传多个图像时遇到问题。 谁能帮我?在此先感谢!!
我正在使用以下代码
let fileParameters = ["array_1": images1Array,
"array_2": images2Array]
func requestUpload(files: [String: Any]? = nil) {
Alamofire.upload( multipartFormData: { multipartFormData in
if let files = files {
for (key, value) in files {
if let images = value as? [UIImage] {
for (index, image) in images.enumerated() {
let imageData = UIImageJPEGRepresentation(image, 1.0)
multipartFormData.append(imageData!, withName: "\(index)", fileName: "\(index).jpg", mimeType: "image/jpg")
}
}
}
}
}, to: path , method: .post , headers: request.headers,
encodingCompletion: { encodingResult in
self.validatedData(of: encodingResult, handler: { (result, error) in
handler(result, error)
})
})
}
所以我想知道如何在特定键中附加多个图像。
服务器请求如下:
"array1":[
{
product_image: img1.jpg
},
{
product_image: img2.jpg
}
],
"array2":[
{
product_image: img3.jpg
}
]

我希望这会有用
制作你的密钥数组类型: -
var tmp = new DatePipe('en-Us').transform(this.today, 'dd:MM:yyyy hh-mm-ss');
使你的循环以递增的顺序创建索引值,如0,1,2,3 ..... N

使用flatmap连接imagesArrays并循环显示图像。
let allImages = fileParameters.values.flatMap{$0}
allImages.enumerated().forEach {
multipartFormData.append(UIImagePNGRepresentation($1.values.first), withName: "product_image\($0)", fileName: "\($0).jpg", mimeType: "image/jpg")
}
