ios - 使用 Swift 2 + AFNetworking 发布图片

Question

我有以下代码

let manager = AFHTTPRequestOperationManager()
    manager.POST(
        "http://shipeala.redmintlabs.com/api/orders/create",
        parameters: params,
        constructingBodyWithBlock: { (formData : AFMultipartFormData!) -> Void in
            formData.appendPartWithFileData(SHOrderImage.getInstance().image!, name: "photo", fileName: "image.jpg", mimeType: "image/*")
        },
        success: { (operation: AFHTTPRequestOperation!,
            ""
        },
        failure: { (operation: AFHTTPRequestOperation!,
            error: NSError!) -> Void in
            ""
        }
    )

我得到了这个错误:

Cannot invoke 'POST' with an argument list of type '(String, parameters: NSDictionary, constructingBodyWithBlock: (AFMultipartFormData!) -> Void, success: (AFHTTPRequestOperation!, AnyObject!) -> Void, failure: (AFHTTPRequestOperation!, NSError!) -> Void)'

有什么想法吗？？

你可以这样做，

        var manager = AFHTTPRequestOperationManager()
        var operation = manager.POST("http://shipeala.redmintlabs.com/api/orders/create", parameters: params, constructingBodyWithBlock: { (formData: AFMultipartFormData!) -> Void in
            formData.appendPartWithFileData(imageData, name: "Photo", fileName: "photo.jpg", mimeType: "image/jpeg")
        }, success: { (operation, responseObject) -> Void in
            println(responseObject)
        }) { (operation, error) -> Void in
            println(error)
        }

        operation.start()
