读取文件

            Python
        
            JavaScript
        
            from e2b_code_interpreter import Sandbox

sandbox = Sandbox.create()
file_content = sandbox.files.read('/path/to/file')
        
            import { Sandbox } from '@e2b/code-interpreter'
const sandbox = await Sandbox.create()
const fileContent = await sandbox.files.read('/path/to/file')

写入单个文件

            Python
        
            JavaScript
        
            from e2b_code_interpreter import Sandbox

sandbox = Sandbox.create()

await sandbox.files.write('/path/to/file', 'file content')
        
            import { Sandbox } from '@e2b/code-interpreter'
const sandbox = await Sandbox.create()
const fileContent = await sandbox.files.read('/path/to/file')

写入多个文件

            Python
        
            JavaScript
        

            from e2b_code_interpreter import Sandbox

sandbox = Sandbox.create()

await sandbox.files.write_files([
    { "path": "/path/to/a", "data": "file content" },
    { "path": "another/path/to/b", "data": "file content" }
])
        

            import { Sandbox } from '@e2b/code-interpreter'
const sandbox = await Sandbox.create()

await sandbox.files.write([
    { path: '/path/to/a', data: 'file content' },
    { path: '/another/path/to/b', data: 'file content' }
])
        

创建文件并获取文件信息

            Python
        
            JavaScript
        
            from e2b_code_interpreter import Sandbox

sandbox = Sandbox.create()

# Create a new file
sandbox.files.write('test_file', 'Hello, world!')

# Get information about the file
info = sandbox.files.get_info('test_file')

print(info)
        
            import { Sandbox } from '@e2b/code-interpreter'

const sandbox = await Sandbox.create()

// Create a new file
await sandbox.files.write('test_file.txt', 'Hello, world!')

// Get information about the file
const info = await sandbox.files.getInfo('test_file.txt')

console.log(info)

            Python
        
            JavaScript
        
            from e2b_code_interpreter import Sandbox

sandbox = Sandbox.create()

# Create a new directory
sandbox.files.make_dir('test_dir')

# Get information about the directory
info = sandbox.files.get_info('test_dir')

print(info)
        
            import { Sandbox } from '@e2b/code-interpreter'

const sandbox = await Sandbox.create()

// Create a new directory
await sandbox.files.makeDir('test_dir')

// Get information about the directory
const info = await sandbox.files.getInfo('test_dir')

console.log(info)

监视沙箱目录变化

监视沙箱目录变化事件

            Python
        
            JavaScript
        

            from e2b_code_interpreter import Sandbox

sandbox = Sandbox.create()
dirname = '/home/user'

# watch目标目录变化
handle = sandbox.files.watch_dir(dirname)
# Trigger file write event
sandbox.files.write(f"{dirname}/my-file", "hello")

# 获取目录中文件变化事件
events = handle.get_new_events()
for event in events:
  print(event)
  if event.type == FilesystemEventType.Write:
    print(f"wrote to file {event.name}")
        

            import { Sandbox, FilesystemEventType } from '@e2b/code-interpreter'

const sandbox = await Sandbox.create()
const dirname = '/home/user'

// watch目标目录变化
const handle = await sandbox.files.watchDir(dirname, async (event) => {
  console.log(event)
  if (event.type === FilesystemEventType.WRITE) {
    console.log(`wrote to file ${event.name}`)
  }
})

// 发起一个文件写入，将导致文件写入事件产生
await sandbox.files.write(`${dirname}/my-file`, 'hello')
        

递归监视沙箱文件目录变化

如果需要监视到目录下子文件夹（包括多级嵌套的文件夹）内容的变化，您可以使用 recursive 参数启用 “递归监视”。

            Python
        
            JavaScript
        

            from e2b_code_interpreter import Sandbox

sandbox = Sandbox.create()
dirname = '/home/user'

# watch目标目录变化
handle = sandbox.files.watch_dir(dirname, recursive=True)
# 触发一个写文件事件
sandbox.files.write(f"{dirname}/my-folder/my-file", "hello")

# 获取目录变化事件并打印
events = handle.get_new_events()
for event in events:
  print(event)
  if event.type == FilesystemEventType.Write:
    print(f"wrote to file {event.name}")
        

            import { Sandbox, FilesystemEventType } from '@e2b/code-interpreter'

const sandbox = await Sandbox.create()
const dirname = '/home/user'

// 获取目录变化事件并打印
const handle = await sandbox.files.watchDir(dirname, async (event) => {
  console.log(event)
  if (event.type === FilesystemEventType.WRITE) {
    console.log(`wrote to file ${event.name}`)
  }
}, {
  recursive: true
})

// 触发一个写文件事件
await sandbox.files.write(`${dirname}/my-folder/my-file`, 'hello')
        

上传文件

上传单个文件

            Python
        
            JavaScript
        

            from e2b_code_interpreter import Sandbox

sandbox = Sandbox.create()

# 从本地读取一个文件
with open("path/to/local/file", "rb") as file:
# 上传该文件到沙箱
  sandbox.files.write("/path/in/sandbox", file)
        

            import fs from 'fs'
import { Sandbox } from '@e2b/code-interpreter'

const sandbox = await Sandbox.create()

// 从本地读取一个文件
const content = fs.readFileSync('/local/path')
// 上传该文件到沙箱
await sandbox.files.write('/path/in/sandbox', content)
        

上传目录、多个文件

            Python
        
            JavaScript
        

            import os
from e2b_code_interpreter import Sandbox

sandbox = Sandbox.create()

def read_directory_files(directory_path):
    files = []
    
    # 获取文件夹中各个文件
    for filename in os.listdir(directory_path):
        file_path = os.path.join(directory_path, filename)
        
        # 跳过文件目录
        if os.path.isfile(file_path):
            # 以二进制方式读取文件内容
            with open(file_path, "rb") as file:
                files.append({
                    'path': file_path,
                    'data': file.read()
                })
    
    return files

files = read_directory_files("/local/dir")
print(files)
# [
#  {"'path": "/local/dir/file1.txt", "data": "File 1 contents..." },
#   { "path": "/local/dir/file2.txt", "data": "File 2 contents..." },
#   ...
# ]

sandbox.files.write_files(files)
        

            const fs = require('fs');
const path = require('path');

import { Sandbox } from '@e2b/code-interpreter'

const sandbox = await Sandbox.create()

// 获取目录中各个文件内容并写入数组
const readDirectoryFiles = (directoryPath) => {
  // Read all files in the local directory
  const files = fs.readdirSync(directoryPath);

  // 映射文件路径和文件内容
  const filesArray = files
    .filter(file => {
      const fullPath = path.join(directoryPath, file);
      // 如果是目录则跳过
      return fs.statSync(fullPath).isFile();
    })
    .map(file => {
      const filePath = path.join(directoryPath, file);
    
      // Read the content of each file
      return {
        path: filePath,
        data: fs.readFileSync(filePath, 'utf8')
      };
    });

  return filesArray;
};

// 读取文件名和文件内容的map
const files = readDirectoryContents('/local/dir');
console.log(files); 
// [
//   { path: '/local/dir/file1.txt', data: 'File 1 contents...' },
//   { path: '/local/dir/file2.txt', data: 'File 2 contents...' },
//   ...
// ]

await sandbox.files.write_files(files)
