本机图像选择器图像文件名为空

问题描述 投票:0回答:1

开发人员,我正在使用react-native-image-picker将图像上传到Nodejs服务器和MongoDB,当我在react native应用程序上选择图像时,它在控制台日志中显示图像fileName =“ null”。我苦苦挣扎了三个星期,找不到任何解决方案。下面我发布了console.log结果:

Response =  {"fileName": null, "fileSize": 13712705, "height": 3024, "isVertical": false, "origURL": "assets-library://asset/asset.HEIC?id=CC95F08C-88C3-4012-9D6D-64A413D254B3&ext=HEIC", "type": "image/jpeg", "uri": "file:///Users/shinobi/Library/Developer/CoreSimulator/Devices/9DBEA6D8-101E-4B9C-9DB0-D1CABA724AAF/data/Containers/Data/Application/44C0E455-2A43-40A3-A2EE-213A39B7743C/tmp/35A90028-55FA-4218-8FB7-34EB1DE62F58.jpg", "width": 4032}  

下面是我的react-native-image-picker代码:

  const selectImage = async () => {
    const options = {
      noData: true,
    };
    ImagePicker.showImagePicker(options, response => {
      console.log('Response = ', response);

      if (response.didCancel) {
        console.log('User cancelled image picker');
      } else if (response.error) {
        console.log('ImagePicker Error: ', response.error);
      } else if (response.customButton) {
        console.log('User tapped custom button: ', response.customButton);
      } else {
        const source = {uri: response.uri};

        // You can also display the image using data:
        // const source = { uri: 'data:image/jpeg;base64,' + response.data };

        setImage(source);

      }
    });
  };

您仅保存图像的URI,以便访问名称和其他数据,因此必须保存“响应”对象

尝试

const source = {fileName: response.fileName, uri: response.uri};

        // You can also display the image using data:
        // const source = { uri: 'data:image/jpeg;base64,' + response.data };

        setImage(source);
