ios - 在文档目录中保存图像时出错

Question

我从我的服务器获取一个图像 URL，我想将其保存在文档目录中。但在我的以下代码中，我收到错误。

这是我的文件 URL 路径 - file:///var/mobile/Containers/Data/Application/7AA1BEDE-DA10-4BD6-8115-06C9DCA53BF2/Documents/https://www.cocubes.com/图片/getimage.aspx%3Ft=l&id=602

文件 URL.path = /var/mobile/Containers/Data/Application/7AA1BEDE-DA10-4BD6-8115-06C9DCA53BF2/Documents/https://www.cocubes.com/images/getimage.aspx? t=l&id=602

“？”正在转换为 %3F，因此我猜(不确定)我无法转到所需的路径。怎么解决这个问题？

static func saveImageInDocsDir(image: UIImage,urlString: NSString) {
    let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
    // choose a name for your image
    //let fileName = "image.jpg"
    // create the destination file url to save your image
    let fileURL = documentsDirectory.appendingPathComponent(urlString as String)
    print(fileURL)
    print(fileURL.path)
    // get your UIImage jpeg data representation and check if the destination file url already exists
    if let data = image.jpegData(compressionQuality: 1.0),
        !FileManager.default.fileExists(atPath: fileURL.path) {
        do {
            // writes the image data to disk
            try data.write(to: fileURL)
            print("file saved")
        } catch {
            print("error saving file:", error)
        }
    }
}

请在下面添加这一行: 让 filePath = filesDirectory.appendingPathComponent(fileURL)

 static func saveImageInDocsDir(image: UIImage,urlString: NSString) {
                let documentsDirectory = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
                // choose a name for your image
                //let fileName = "image.jpg"
                // create the destination file url to save your image
                let fileURL = documentsDirectory.appendingPathComponent(urlString as String)
                print(fileURL)
                print(fileURL.path)
                // get your UIImage jpeg data representation and check if the destination file url already exists
                let filePath = documentsDirectory.appendingPathComponent(fileURL)
                if let data = image.jpegData(compressionQuality: 1.0),
                    !FileManager.default.fileExists(atPath: filePath.path) {
                    do {
                    // writes the image data to disk
                    try data.write(to: fileURL)
                    print("file saved")
                    } catch {
                    print("error saving file:", error)
                }
        }
    }
