javascript - 从 PowerShell 脚本执行 Nodejs 脚本

问题描述

我正在尝试从 PowerShell 脚本执行 nodejs 脚本。我将几个参数传递给传递给 nodejs 的 Powershell。

在将它们传递给 nodejs 之前，我将它们绑定到 JSON 对象中。它在大多数情况下都可以正常工作，但以下情况除外：如果 Powershell 中的参数输入之一在两个单词之间有空格。例如

$requestBody='{"name":"Kiran","Place":"San Diego"}'
//Here I have space in "San Diego" if I pass "SanDiego" it worked.

PowerShell 代码

$Header = '{"xyz-qer-01":"Tew23343"}'

$endPoint="https://r0zvc2xdx7.execute-api.us-west-2.amazonaws.com"
$accessKey="<>"
$screteKey="<>"
$method='GET'
$requestBody='{"name":"Kiran","Place":"SanDiego"}'
$pathTemplate='/dev/network-provisioning/api/v1/subnets'
$additionalParam='{"header":{"xyz-qer-01":"Tew23343"}}'

$Filename = AWSSigner.js;

$Param = @{"endPoint"=$endPoint;"accessKey"=$accessKey;"screteKey"=$screteKey;"method"=$method;"requestBody"=$requestBody | ConvertFrom-Json;"pathTemplate"=$pathTemplate;"additionalParam"=$additionalParam | ConvertFrom-Json} | ConvertTo-Json -Compress

$Param2 = $Param | ConvertTo-Json -Compress
Write-Output = $Param2


 $Result = C:\Users\kp250041\Desktop\Myfiles\node C:\Users\kp250041\Desktop\Myfiles\AWSSigner.js $Param2
 Write-Output $Result

节点 JS 代码

let awsbody = process.argv[2].split('\\').join(' ') || '{}';
console.log(awsbody);
var obj = JSON.parse(awsbody);

console.log("Main Request:" + "\n");
console.log(obj);

console.log("\n" + "obj.endPoint      - " + obj.endPoint);
console.log("obj.awsAccessKey         - " + obj.accessKey);
console.log("obj.awsSecreteKey        - " + obj.screteKey);
console.log("obj.awsPathTemplate      - " + obj.pathTemplate);
console.log("obj.method               - " + obj.method);
console.log(obj.additionalParam);
console.log(obj.requestBody);

这是错误
