替换文件中的单词以添加另一个文件内容 [重复]-解网

输入文件（csv）。

NAME,TYPE,ACCESS_TOKEN
dev765,datatype,Token765
dev879,datatype,Token879

附加文件：

{
  "file": "string",
  "mapping": {
    "columns": [
      {
        "type": "NAME"
      },
      {
        "type": "TYPE"
      },
      {
        "type": "ACCESS_TOKEN"
      }
    ],
    "delimiter": ",",
    "header": true,
    "update": true
  }
}

目标是将“附加文件”中的“字符串”替换为“输入文件”的内容，并带有换行符。因此，生成的“附加文件”文件应如下所示：

{
  "file": "NAME,TYPE,ACCESS_TOKEN\n dev765,datatype,Token765\n dev879,datatype,Token879",
  "mapping": {
    "columns": [
      {
        "type": "NAME"
      },
      {
        "type": "TYPE"
      },
      {
        "type": "ACCESS_TOKEN"
      }
    ],
    "delimiter": ",",
    "header": true,
    "update": true
  }
}

我实际需要的是“Append.txt”文件的第一行：

{
  "file": "_the_content_of_the_input_file_with_\n_break",
  REST OF THE FILE AS IT IS
  ....
  ....
}

如果文件是纯文本，我可以在开头或结尾附加整个文件。或者用另一个词替换一个词。但只是不知道如何处理上述格式以及如何用整个文件替换单词。

python 替换

with (open("input.csv", "r") as infile,
      open("append_file.json", "r") as append_file,
      open("output_file.json", "w") as outfile):

    infile_content = infile.read().strip()
    infile_content = infile_content.replace("\n", "\\n ")
    
    # You can also use the join() approach
    # infile_content = "\n ".join(infile.readlines())

    append_file_content = json.load(append_file)
    append_file_content["file"] = infile_content

    json.dump(append_file_content, outfile, indent=2)

测试代码：

import json

input_file_content = """NAME,TYPE,ACCESS_TOKEN
dev765,datatype,Token765
dev879,datatype,Token879
"""

input_file_content = "\n ".join(input_file_content.splitlines())

append_file_content = {
  "file": "string",
  "mapping": {
    "columns": [
      {
        "type": "NAME"
      },
      {
        "type": "TYPE"
      },
      {
        "type": "ACCESS_TOKEN"
      }
    ],
    "delimiter": ",",
    "header": True,
    "update": True
  }
}

append_file_content["file"] = input_file_content
print(json.dumps(append_file_content, indent=2))

{
  "file": "NAME,TYPE,ACCESS_TOKEN\n dev765,datatype,Token765\n dev879,datatype,Token879",
  "mapping": {
    "columns": [
      {
        "type": "NAME"
      },
      {
        "type": "TYPE"
      },
      {
        "type": "ACCESS_TOKEN"
      }
    ],
    "delimiter": ",",
    "header": true,
    "update": true
  }
}
