Postman遇到脚本不支持replaceIn函数

1、问题现象

2、代码处理

function replaceVariables(template) {// 获取所有变量（环境变量+全局变量）const variables = pm.environment.toObject();const globalVars = pm.globals.toObject();const allVars = {...globalVars, ...variables};let result = template;// 替换所有 {{variable}} 格式的变量for (const [key, value] of Object.entries(allVars)) {const regex = new RegExp(`\\{\\{${key}\\}\\}`, 'g');result = result.replace(regex, value);}return result;
}

var appId='xxxxxxxxxxxx'
var appKey='xxxxxxxxxxxxxxxx'
// console.log(`appId=${appId}, appKey=${appKey}, appToken=${appToken}`)
function replaceVariables(template) {// 获取所有变量（环境变量+全局变量）const variables = pm.environment.toObject();const globalVars = pm.globals.toObject();const allVars = {...globalVars, ...variables};let result = template;// 替换所有 {{variable}} 格式的变量for (const [key, value] of Object.entries(allVars)) {const regex = new RegExp(`\\{\\{${key}\\}\\}`, 'g');result = result.replace(regex, value);}return result;
}
// 获取请求信息
var method = 'POST'
var path='/api/xxx/sync/v1/xxx'
var body=replaceVariables(pm.request.body.toString());
console.log(`‘111111’+${body}`)
var contentType="application/json"
var dateString = new Date().toGMTString();
var authorization = "";
if(body==""){console.log(`[${method}] ${path}`)authorization = 'xxx-4' + method + path + contentType + dateString 
} else {console.log(`[${method}] ${path}\n${body}`)authorization = 'xxx-4' + method + path + contentType + dateString +  CryptoJS.SHA256(body).toString(CryptoJS.enc.Hex)
}console.log(`authorization ${authorization}`)
authorization = CryptoJS.HmacSHA256(authorization, appKey).toString(CryptoJS.enc.Hex)
authorization = 'xxx-4 ' +appId + ':' + authorization
console.log(`authorization11 ${authorization}`)
// 设置请求头
pm.request.headers.upsert({key: 'xxx-Docs-Date',value: dateString
})
pm.request.headers.upsert({key: 'Content-Type',value: contentType
})
pm.request.headers.upsert({key: 'xxx-Docs-Authorization',value: authorization
})
// console.log(pm.request.getHeaders());

3、执行结果

原先自己尝试写死去构造json转字符串，带入签名一直不通过，尝试使用代码替换可行，特此记录一下。
