问题描述

Android测试机上传图片时报错（iOS正常）：
{"error": "TypeError: Network request failed", "status": "FETCH_ERROR"}

问题分析

上传图片使用库是"react-native-image-crop-picker": "^0.39.0"

问题解决

react-native-image-crop-picker返回的image.sourceURL和filename只在iOS下可用，所以代码改成这样：

      const filePath = Platform.OS === 'ios' ? image.sourceURL : image.path;
      const fileName =
        Platform.OS === 'ios' ? image.filename : image.path.split('/').pop();

      let formData = new FormData();
      const file = {
        uri: filePath,
        type: 'multipart/form-data',
        name: fileName,
      };
      formData.append('file', file);
