如何逐行循环遍历文本文件，并将每一行附加到数组？

Question

我正在尝试逐行遍历 .txt，但似乎没有执行此操作的好方法。

想法是提取每一行并将其附加到数组。

Answer 1

假设你有一个像

这样的文本文件

并且我正在尝试从 blob 存储中读取同一个文件。为了将每一行变成一个数组，您可以使用一个带有 split() 函数的组合连接器。这是我的逻辑应用程序屏幕截图以供参考：-

这里是 compose 连接器中的拆分表达式

split(body('Get_blob_content_(V2)'),'
')

结果

下面是我的逻辑应用程序的代码视图：

{
    "definition": {
        "$schema": "https://schema.management.azure.com/providers/Microsoft.Logic/schemas/2016-06-01/workflowdefinition.json#",
        "actions": {
            "Compose": {
                "inputs": "@split(body('Get_blob_content_(V2)'),'\r\n')",
                "runAfter": {
                    "Get_blob_content_(V2)": [
                        "Succeeded"
                    ]
                },
                "type": "Compose"
            },

        }
    }
}

如何逐行循环遍历文本文件，并将每一行附加到数组？

How do I loop though a text file, line by line, and append each line to an array?
