AlamoFileImage:如何使用POST请求下载图像

您可以使用 af_setImage 方法来自 AlamofireImage 扩展 UIImageView 并通过任何 URLRequestConvertible 参数例如,创建 URLRequest 具有Alamofire初始值设定项的实例:

let urlPath = "https://host_name/project_name/GetImage"
if var imageRequest = try? URLRequest(url: urlPath, method: .post) {
    imageRequest.addValue("token", forHTTPHeaderField: "token_field")
    imageView.af_setImage(withURLRequest: imageRequest)
}

因为我们必须在HTTPBodyData中发送参数,根据Loe的回答,我对代码进行了一些更改。以下是我们的新代码:

let urlPath = "https://host_name/project_name/GetImage"
let parameters:[String: Any] = [
        "token": "tokenValue",
        "imageName": "imageName"
    ]
let dataRequest = Alamofire.request(urlPath,
                                    method: HTTPMethod.post,
                                    parameters: parameters,
                                    encoding: JSONEncoding.default,
                                    headers: [:])
guard let imageRequest = dataRequest.request else {
    return
}
imageView.af_setImage(withURLRequest: imageRequest)

重点是首先,我们创建 DataRequest 对象,然后将其转换为 URLRequest 使用键入 Alamofire.request() 方法
