FORM表单里有一个字段是根据几个字段hash得到的值，每次去算hash很不方便，可以这样去设置。
在pre-request script里输入：
var data = request.data.c_source +
request.data.c_affiliate_id +
request.data.c_order_id +
'xxxxx';
var hash = CryptoJS.MD5(data).toString();
pm.environment.set("token", hash);
// 常用操作
// 获取query参数
var str = pm.request.url.query.get("version");
// 获取post表单里的值
var str = request.data.字段名
// 获取提交的json数据
var post = JSON.parse(pm.request.body.raw);
// 向header加头
pm.request.headers.add({
key: 'x-ShareASale-Date',
value: myTimeStamp
});
在Form表单里输入: {{token}} 就可以自动计算了
怎么取值，可以参考PostMan的官方文档
https://learning.postman.com/docs/writing-scripts/script-references/postman-sandbox-api-reference/#scripting-with-request-data
自动计算token并加到postman的请求里：
var salt = "xxxx";
var post = JSON.parse(pm.request.body.raw);
var hash = CryptoJS.MD5(post.source_account_id + salt).toString();
post.token = hash;
pm.request.body.raw = JSON.stringify(post);
// 更多的加密方法 SHA256
var SHA256 = CryptoJS.SHA256(str).toString();
// BASE64
const data = CryptoJS.enc.Utf8.parse("test")
const base64 = CryptoJS.enc.Base64.stringify(data)
在PostMan里使用请求获取到的token当成认证参数
// linkhaitao
var new_Client_id = "x"
var new_Client_secret = "x"
var username = "x"
var scope = "x"
var token = MyUtils.BASE64(new_Client_id+":"+new_Client_secret)
// 请求可以参考: http://www.postmanlabs.com/postman-collection/Request.html#~definition
var postData = [
{key: 'grant_type', value: 'password'},
{key: 'username', value: username},
{key: 'scope', value: scope}
];
var requestOption = {
url: 'https://api.xxx.com/token',
method: 'POST',
header: {
"Authorization": "Basic " + token,
"Content-Type": "application/json"
},
body: {
mode: 'urlencoded', // 这里为什么值，下面就为什么key，如果raw, formdata, urlencoded之类
urlencoded: postData
// mode: 'raw',
// raw: JSON.stringify(postData)
}
}
pm.sendRequest(requestOption, function (err, res) {
console.log("获取到的token", res.json());
pm.environment.set("token", res.json().access_token)
pm.request.headers.add({
key: "Authorization",
value: "Bearer " + res.json().access_token
});
})
向PostMan的Query地址里加参数
let token = "xxoo"
pm.request.addQueryParams({
key: "token",
value: token
});
PostMan里定义和使用全局函数
在某一个文件夹里的”pre request script”里，定义下面的内容
MyUtils = {
SHA256: function SHA256(s){
var chrsz = 8;
var hexcase = 0;
function safe_add (x, y) {
