Question

我正在尝试使用API将Pocket书签备份到csv和html，但是在打印数组的每个元素时都没有空白行或没有具体引用每个元素的问题。

使用者密钥和访问令牌已在curl命令中替换为*。

#!/bin/bash

curl https://getpocket.com/v3/get --insecure -X POST -H "Content-Type: application/json" -H "X-Accept: application/json" -d "{\"consumer_key\":\"*\", \"access_token\":\"*\", \"detailType\":\"complete\"}" > "pocketData"

awk 'BEGIN {
        FS="\"[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]\":" 
    }
    {
        for (i = 2; i <= NF; i++)           
        {
            count++
            gsub("\{", "", $i)
            gsub("\}", "", $i)
            gsub("\\", "", $i)
            gsub("\"", "", $i)
            gsub("\\n", "", $i)
            split($i, attributeArray, ",")


            print attributeArray[1]
            print attributeArray[2]
            print attributeArray[3]
            print attributeArray[4]
            print attributeArray[5]
            print attributeArray[6]
            print attributeArray[7]
            print attributeArray[8]
            print attributeArray[9]
            print attributeArray[10]
        #...
            print attributeArray[100]
            #print

        }
    }' "pocketData"

输出看起来像这样，其中包含许多空行，因为并非所有元素都存在：

Answer 1

使用split function的返回值：

split()返回创建的元素数。

        n = split($i, attributeArray, ",")
        for (i = 1; i <= n; i++) print attributeArray[i]

但是，请勿使用awk解析JSON。使用JSON解析器。假设某个属性的值包含逗号：

"excerpt":"Good news to everyone, except you!"

您的属性数组现在无用了。

用awk打印数组的每个元素
