postman中设置全局动态sign签名脚本
进入某个collection的全局edit设置:
在"Pre-request Scripts"选项卡设置全局脚本:
全局脚本贴上代码:
function getCurrentDate() { var myDate=new Date(); // 获取当前时间戳 var year = myDate.getFullYear(); // 获取年份 var month = myDate.getMonth() + 1; // 获取月份 month = month < 10 ? "0" + month : month; var days = myDate.getDate(); // 获取日期 days = days < 10 ? "0" + days : days; var hours = myDate.getHours() + 1; // 获取时并+1 var min = myDate.getMinutes(); // 获取分 var seconds = myDate.getSeconds(); // 获取秒 hours = hours < 10 ? "0" + hours : hours; min = min < 10 ? "0" + min : min; seconds = seconds < 10 ? "0" + seconds : seconds; // 定义时间格式并设置为环境变量 return year + "-" + month + "-" + days + " " + hours +":"+ min +":"+ seconds; } // appkey & secret code var secretCode = 'ctw7i3cV6eu4pNCH3n4BMzkannNJX4jQ'; var timestamp = getCurrentDate(); // 设置全局请求域名地址,和项目上下文路径 pm.environment.set("URL", "http://127.0.0.1:8080/ecoupon-redemption-system"); pm.environment.set("timestamp", timestamp); // console.log("全部请求参数:" + request.data); request.data["timestamp"] = timestamp; var keys = Object.keys(request.data).sort() //请求参数名按照ASCII码升序排序 //拼接待签名字符串 var str = [] for (var p = 0; p < keys.length; p++) { if(keys[p] == "sign" || keys[p] == "signmethod" || request.data[keys[p]] === ""){ // "==" ==宽松相等,隐性类型转换,值相等,返回true; "===" 严格相等,值和类型都相等,返回true continue; } str.push(keys[p] + "=" + request.data[keys[p]]); } var signStr = str.join("&") + secretCode; console.log("待加密字符串 signStr == " + signStr); //MD5加密签名规格,并赋值给环境变量`sign` pm.environment.unset("sign"); var sign = CryptoJS.MD5(signStr).toString().toUpperCase(); console.log("计算出的签名 sign == " + sign); pm.environment.set("sign", sign);
在这里计算好的sign变量,在request里动态获取值: {{sign}}
如果在script脚本中有使用console.log打印日志的情况,可以打开console控制台查看打印出来的日志:
