PostMan Pre-request Script 生成api签名

api接口都会有签名校验，这个校验在我们api测试的时候很不方便，这里来利用postman 前置处理来生成sig 提交。

PostMan设置提交参数

这里有两个东西我们需要在 Pre-request Script 中预生成来填入提交数据中。

  sig:签名串create_time:提交时间

##Pre-request Script 预处理，生成sig

    var appid = 'your appid';var appkey = 'your appkey';//获取当前时间function createTime() {return (new Date()).valueOf();}var time = createTime();var method = request.method;//提交方式delete request.data["sig"];//将sig排除排序console.log(request.data);var keys = Object.keys(request.data), i, len = keys.length;keys.sort();//根据key经行排序console.log(keys)// Build the request body string from the Postman request.data objectvar requestBody = "";var firstpass = true;// 构造数据为 key=param&key=param....字符串for(var index in keys){if(!firstpass){requestBody += "&";}if(keys[index]=="create_time"){request.data[keys[index]]=time;console.log(request.data[keys[index]]);}requestBody += keys[index] + "=" + request.data[keys[index]];firstpass = false;}console.log(requestBody);//将构造数据url编码var encodeURIdata = encodeURIComponent(requestBody);console.log(encodeURIdata);appkey=appkey+"&";//生成密钥var signHmacSHA1=CryptoJS.HmacSHA1(encodeURIdata, appkey);console.log(signHmacSHA1);var base64sha256 = CryptoJS.enc.Base64.stringify(signHmacSHA1);console.log(base64sha256);//    将变量放入postman 变量中postman.setEnvironmentVariable('appid', appid);postman.setEnvironmentVariable('create_time', time);postman.setEnvironmentVariable('signature', base64sha256);

这样每次提交数据就能 预先构造出sig然后提交了。
