javascript - resolveLocalFileSytemURL 返回 FileError {代码 :5}?

Question

我正在做一个 React 项目，我是第一次使用 Cordova 插件。我可以正确拍照，但现在我想使用持久存储将它们本地存储在设备上。我找到了很好的文档，但由于某种原因无法使此代码正常工作。如果有人可以提供帮助，我将不胜感激!

这是我的函数:

takePicture() {
    navigator.camera.getPicture(
        imageData => {
            this.setState({image: imageData});

            let path = 'filesystem:' + imageData;

            window.resolveLocalFileSystemURL(
                path,
                (entry) => {
                    window.requestFileSystem(
                        LocalFileSystem.PERSISTENT,
                        50 * 1024 * 1024,
                        (fileSys) => {
                            //The folder is created if doesn't exist
                            fileSys.root.getDirectory(
                                'Observation Photos',
                                {create:true, exclusive: false},
                                directory => {
                                    let d = new Date(),
                                        n = d.getTime(),
                                        filename = n + '.jpg';
                                    entry.moveTo(directory, filename, (entry) => {
                                        Photos.insert(entry);
                                    }, handleError);
                                },
                                handleError
                            );
                        },
                        handleError
                    );
                }, (error) => {
                    console.log(error);
                }
            );
        }, message => {
            console.log(message);
        }
    );
}

这是我传递的路径示例:

filesystem:file:///storage/emulated/0/Android/data/com.id1b9kkvri4mj2dnqkf9p/cache/1470171102308.jpg

在检查器中返回这个:

FileError {code: 5}

Answer 1

路径的值应该是Android/data/com.id1b9kkvri4mj2dnqkf9p/cache/1470171102308.jpg;

所以它需要一个小改动:

let path = imageData.replace("file:///storage/emulated/0/","");
