"NOT" "element" "IN_LIST" "paths_to_search" "NOT" "element" "IN_LIST" "paths_to_search" "NOT" "element" "IN_LIST" "paths_to_search"

我明白你的问题。你想知道如何判断一个元素是否不在一个给定的路径列表中。你可以使用以下伪代码来实现这个功能：

function isElementNotInList(element, paths_to_search):
    for path in paths_to_search:
        if element not in path:
            return True
    return False

在这个伪代码中，我们遍历给定的路径列表，如果某个路径中不存在该元素，则返回 True。如果所有路径中都存在该元素，则返回 False。

请注意，这只是一个伪代码示例，你需要根据自己的编程语言和需求进行具体实现。希望能帮到你！如果你还有其他问题，请继续提问。

dcmSOPs = findSOPs(path) paths = list(map(str,path.split("\\"))) patient = paths[-2] time = paths[-1] rvFile = path+'\\RS.{}'.format(patient)+'.CT_1.dcm'.format(time) ds = pydicom.dcmread(rvFile) contours = ds.ROIContourSequence dcmFile = path+'\\CT.{}'.format(patient)+'.Image {}.dcm'.format(str(int(1))) ds = pydicom.dcmread(dcmFile) dcmOrigin = ds.ImagePositionPatient dcmSpacing = ds.PixelSpacing numberOfContours = len(contours[labelID].ContourSequence) print("time",time,": numberOfContourPts=",numberOfContours) cuts = [] 按行解释这段代码

Sure, here is an explanation of the provided code snippet:

1. `dcmSOPs = findSOPs(path)` - This line is calling a function `findSOPs` that presumably returns a list of DICOM file paths in the given `path` directory.

2. `paths = list(map(str,path.split("\\")))` - This line is splitting the `path` string using the backslash as a separator and then converting each element to a string and storing them in a list called `paths`.

3. `patient = paths[-2]` - This line is extracting the second last element from the `paths` list and storing it in a variable called `patient`.

4. `time = paths[-1]` - This line is extracting the last element from the `paths` list and storing it in a variable called `time`.

5. `rvFile = path+'\\RS.{}'.format(patient)+'.CT_1.dcm'.format(time)` - This line is creating a file path for a DICOM file with the name `RS.<patient>.CT_1.dcm` in the given `path` directory.

6. `ds = pydicom.dcmread(rvFile)` - This line is reading the DICOM file at the `rvFile` path using the `pydicom` library and storing it in a `Dataset` object called `ds`.

7. `contours = ds.ROIContourSequence` - This line is extracting the contour sequence from the `ds` dataset and storing it in a variable called `contours`.

8. `dcmFile = path+'\\CT.{}'.format(patient)+'.Image {}.dcm'.format(str(int(1)))` - This line is creating a file path for a DICOM file with the name `CT.<patient>.Image 1.dcm` in the given `path` directory.

9. `ds = pydicom.dcmread(dcmFile)` - This line is reading the DICOM file at the `dcmFile` path using the `pydicom` library and storing it in a `Dataset` object called `ds`.

10. `dcmOrigin = ds.ImagePositionPatient` - This line is extracting the image position patient from the `ds` dataset and storing it in a variable called `dcmOrigin`.

11. `dcmSpacing = ds.PixelSpacing` - This line is extracting the pixel spacing from the `ds` dataset and storing it in a variable called `dcmSpacing`.

12. `numberOfContours = len(contours[labelID].ContourSequence)` - This line is calculating the number of contour points for the `labelID`-th contour sequence in `contours` and storing it in a variable called `numberOfContours`.

13. `print("time",time,": numberOfContourPts=",numberOfContours)` - This line is printing the `time` and `numberOfContours` values to the console.

14. `cuts = []` - This line is initializing an empty list called `cuts`.

vue3+springboot+element-plus生成附件上传并浏览功能

要实现Vue3和Spring Boot框架下的Element Plus附件上传和浏览功能，可以按照以下步骤进行操作：

1. 前端实现

在Vue3项目中，可以使用Element Plus提供的el-upload组件进行上传，同时利用axios发送上传请求，具体实现可以参考上一篇回答的代码示例。

在附件浏览的功能中，可以使用Element Plus提供的el-dialog组件和el-table组件，具体实现可以参考以下代码示例：

<template>
  <div>
    <el-upload
      class="upload-demo"
      action="/api/upload"
      :on-success="handleSuccess"
      :file-list="fileList"
      multiple
      :limit="3"
      :on-exceed="handleExceed"
      :headers="headers">
      <el-button size="small" type="primary">点击上传</el-button>
      <div slot="tip" class="el-upload__tip">只能上传jpg/png文件，且不超过500kb</div>
    </el-upload>
    <el-button type="primary" @click="showDialog">查看附件</el-button>
    <el-dialog title="附件列表" :visible.sync="dialogVisible" width="50%">
      <el-table :data="fileTableData" border>
        <el-table-column prop="filename" label="文件名"></el-table-column>
        <el-table-column prop="size" label="文件大小"></el-table-column>
        <el-table-column label="操作">
          <template v-slot="scope">
            <a :href="'/api/download/' + scope.row.filename">下载</a>
          </template>
        </el-table-column>
      </el-table>
    </el-dialog>
  </div>
</template>

<script>
import axios from 'axios'

export default {
  data() {
    return {
      fileList: [],
      headers: {
        Authorization: 'Bearer ' + localStorage.getItem('token'),
      },
      dialogVisible: false,
      fileTableData: [],
    }
  },
  methods: {
    handleSuccess(response, file, fileList) {
      this.$message.success('上传成功')
      this.fileList = fileList
    },
    handleExceed(files, fileList) {
      this.$message.warning(`当前限制选择 3 个文件，本次选择了 ${files.length} 个文件，共选择了 ${fileList.length + files.length} 个文件`)
    },
    showDialog() {
      axios.get('/api/files')
        .then(response => {
          this.fileTableData = response.data
          this.dialogVisible = true
        })
        .catch(error => {
          console.log(error)
        })
    },
  },
}
</script>

其中，`/api/files`接口可以用来获取已上传的附件列表，返回的数据格式可以是一个包含文件名和文件大小的对象数组，例如：

[
  { "filename": "file1.txt", "size": "123KB" },
  { "filename": "file2.jpg", "size": "456KB" },
  { "filename": "file3.pdf", "size": "789KB" }
]

2. 后端实现

在Spring Boot项目中，可以使用Spring Boot提供的MultipartFile类来处理上传的附件，同时可以使用Spring Boot提供的ResponseEntity类来处理下载请求，具体实现可以参考以下代码示例：

@RestController
@RequestMapping("/api")
public class FileController {

    private static final String UPLOAD_FOLDER = "uploads/";

    @PostMapping("/upload")
    public ResponseEntity<?> uploadFile(@RequestParam("file") MultipartFile file) {
        try {
            String filename = file.getOriginalFilename();
            String filepath = Paths.get(UPLOAD_FOLDER, filename).toString();
            Files.write(Paths.get(filepath), file.getBytes());
            return ResponseEntity.ok().build();
        } catch (IOException e) {
            e.printStackTrace();
            return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
        }
    }

    @GetMapping("/files")
    public ResponseEntity<List<FileMetadata>> getFiles() {
        List<FileMetadata> files = new ArrayList<>();
        File uploadFolder = new File(UPLOAD_FOLDER);
        if (uploadFolder.exists()) {
            File[] fileList = uploadFolder.listFiles();
            if (fileList != null && fileList.length > 0) {
                for (File file : fileList) {
                    FileMetadata metadata = new FileMetadata(file.getName(), humanReadableByteCount(file.length()));
                    files.add(metadata);
                }
            }
        }
        return ResponseEntity.ok(files);
    }

    @GetMapping("/download/{filename:.+}")
    public ResponseEntity<Resource> downloadFile(@PathVariable String filename) {
        Path filepath = Paths.get(UPLOAD_FOLDER, filename);
        Resource resource;
        try {
            resource = new UrlResource(filepath.toUri());
        } catch (MalformedURLException e) {
            e.printStackTrace();
            return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).build();
        }
        if (resource.exists() && resource.isReadable()) {
            HttpHeaders headers = new HttpHeaders();
            headers.add(HttpHeaders.CONTENT_DISPOSITION, "attachment; filename=" + filename);
            return ResponseEntity.ok().headers(headers).body(resource);
        } else {
            return ResponseEntity.notFound().build();
        }
    }

    private static String humanReadableByteCount(long bytes) {
        if (bytes < 1024) {
            return bytes + "B";
        }
        int exp = (int) (Math.log(bytes) / Math.log(1024));
        String pre = "KMGTPE".charAt(exp - 1) + "i";
        return String.format("%.1f%sB", bytes / Math.pow(1024, exp), pre);
    }

    private static class FileMetadata {
        private final String filename;
        private final String size;

        public FileMetadata(String filename, String size) {
            this.filename = filename;
            this.size = size;
        }

        public String getFilename() {
            return filename;
        }

        public String getSize() {
            return size;
        }
    }
}

其中，`/api/download/{filename}`接口可以用来处理下载请求，返回的是一个附件文件流，可以在前端实现中通过a标签的href属性来实现下载。
