android - Cordova 插件文件路径 : Unable to resolve filesystem path

Question

尝试通过 android/ios 库使用 cordova-plugin-camera 从 ionic 应用程序上传图像。它在 ios 上工作得很好，但在解析路径时抛出错误，我正在使用 cordova-plugin-filepath 来解析文件路径。

但在 this.filePath.resolveNativePath(imagePath) 方法中解析 native 路径时，它总是抛出以下错误:

{code: 0 ; message: "Unable to resolve filesystem path."}

这是我上传图片的代码:

var options = {
  quality: 60,
  targetWidth:900,
  sourceType: sourceType,
  saveToPhotoAlbum: false,
  correctOrientation: true
};


// Get the data of an image
this.camera.getPicture(options).then((imagePath) => {
  if (this.platform.is('android') && sourceType === this.camera.PictureSourceType.PHOTOLIBRARY) {
    console.log('image path',imagePath)
    this.filePath.resolveNativePath(imagePath)
      .then(res => {
        let correctPath = res.substr(0, res.lastIndexOf('/') + 1).toString();
        let currentName = imagePath.substring(imagePath.lastIndexOf('/') + 1, imagePath.length).toString();
        this.copyFileToLocalDir(correctPath, currentName, this.createFileName());
      }).catch(err=>{
        console.log('unable to resolve file path issue', err)
      });
  } else {
    var currentName = imagePath.substr(imagePath.lastIndexOf('/') + 1);
    var correctPath = imagePath.substr(0, imagePath.lastIndexOf('/') + 1);
    console.log(currentName,correctPath)
    this.copyFileToLocalDir(correctPath, currentName, this.createFileName());
  }
}, (err) => {
  console.log(err);
});

我什至尝试使用以下代码但没有成功:

window.FilePath.resolveNativePath(imagePath)
      .then(res => {
        let correctPath = res.substr(0, res.lastIndexOf('/') + 1).toString();
        let currentName = imagePath.substring(imagePath.lastIndexOf('/') + 1, imagePath.length).toString();
        this.copyFileToLocalDir(correctPath, currentName, this.createFileName());
      }).catch(err=>{
        console.log('unable to resolve file path issue', err)
      });

这是我的插件详细信息:

只需将 file:// 添加到 imagePath 即可。

代码 fragment

this.camera.getPicture(options).then((imagePath) => {
  if (this.platform.is('android') && sourceType === this.camera.PictureSourceType.PHOTOLIBRARY) {
  //insert this line will solve the error
  imagePath = 'file://' + imagePath;
    console.log('image path',imagePath)
    this.filePath.resolveNativePath(imagePath)
      .then(res => {
        let correctPath = res.substr(0, res.lastIndexOf('/') + 1).toString();
        let currentName = imagePath.substring(imagePath.lastIndexOf('/') + 1, imagePath.length).toString();
        this.copyFileToLocalDir(correctPath, currentName, this.createFileName());
      }).catch(err=>{
        console.log('unable to resolve file path issue', err)
      });
  } else {
    var currentName = imagePath.substr(imagePath.lastIndexOf('/') + 1);
    var correctPath = imagePath.substr(0, imagePath.lastIndexOf('/') + 1);
    console.log(currentName,correctPath)
    this.copyFileToLocalDir(correctPath, currentName, this.createFileName());
  }
}, (err) => {
  console.log(err);
});

解释

你之前写的代码只适用于android版本9以下的android版本。对于android版本9及以上无法识别文件路径。
