Paw 是一款Mac上原生界面的HTTP客戶端測試工具富纸，最讓人稱道的是強(qiáng)大的Dynamic Values機(jī)制，而且內(nèi)置了大量的Dynamic Values稽鞭。一般我們在進(jìn)行接口測試時(shí)诵闭，經(jīng)常會(huì)遇到一些需要?jiǎng)討B(tài)計(jì)算的值采蚀，比如唯一的訂單號(hào)熊赖、簽名来屠、加密計(jì)算等，可用它內(nèi)置的Dynamic Values來完成震鹉。

順便提一下俱笛，內(nèi)置的Dynamic Values如果是來源于其它請求的Request或Respone時(shí)，會(huì)自動(dòng)形成執(zhí)行時(shí)的依賴鏈传趾。在執(zhí)行有依賴的請求迎膜，會(huì)先依次執(zhí)行所有的被依賴請求。這點(diǎn)在測試中也非常的好用浆兰。
現(xiàn)實(shí)中也存在一些更復(fù)雜的場景磕仅，動(dòng)態(tài)計(jì)算的情況不能用內(nèi)置的或插件中的Dynamic Values來完成珊豹。這時(shí)，還可以先安裝JS Script這個(gè)插件榕订，就可以用Javascript調(diào)用Paw提供的一些Api接口來定制Dynamic Values平夜。下面舉兩個(gè)示例。
- 定制計(jì)算請求體的內(nèi)容
function evaluate(context){
var request = context.getCurrentRequest();
// A1156797
var uin = getParameterFinallyValueByName(request, '_uin');
var head_str = '<head><uin>' + uin + '</uin><sversion>10000</sversion><time>' + getDateFormatString() + '</time><sign_type>HMAC_SHA512</sign_type></head>';
return head_str ;
}
function getParameterFinallyValueByName(request, paramName) {
var dynamicStringObj = request.getUrlParameterByName(paramName, true);
var component = dynamicStringObj.getComponentAtIndex(0);
return (typeof component == 'string') ? component : component.getEvaluatedString();
};
// 這個(gè)版本的Paw定制返回時(shí)間串有bug
function getDateFormatString() {
var d = new Date();
var year = d.getMonth() + 1;
var day = d.getDate();
var month = d.getMonth() + 1;
var hour = d.getHours();
var min = d.getMinutes();
var sec = d.getSeconds();
var date_str = d.getFullYear() + '-' + (month < 10 ? '0' + month : month) + '-' +(day < 10 ? '0' + day : day) + ' ' + (hour < 10 ? '0' + hour : hour) + ':' + (min < 10 ? '0' + min : min) + ':' + (sec < 10 ? '0' + sec : sec) ;
return date_str;
}
- 在請中再發(fā)起另一個(gè)附加請求
function evaluate(context){
var requestUuid = context.getCurrentRequest().id;
var baseUrl = dynamicValue(requestUuid, "_urlBase");
var callback_method = dynamicValue(requestUuid, "_callbackMethod");
var supUid = dynamicValue(requestUuid, "_supuid");
var rawOrderIds = dynamicValue(requestUuid, '_orderidArray');
var totalCount = dynamicValue(requestUuid, '_totalCount');
console.log(rawOrderIds);
if(rawOrderIds == "[]" | totalCount == "0") { return ""; }
var orderIds = rawOrderIds.replace(/[\[\]"]/g, '');
console.log(orderIds);
var arrOrders = orderIds.split(",");
var result_str = "";
for(var i = 0; i < arrOrders.length; ++i) {
var callbackUrl = baseUrl + callback_method + "?limittype=1&outorderid=NT&remark=KARA&card_no=SB&supuid=" + supUid + "&orderid=" + arrOrders[i]
console.log(callbackUrl);
var tmp = execute_callback(callbackUrl);
result_str += arrOrders[i] + ": " + tmp + "\n";
}
///////////////////////////////// notify stub
var notifyUrl = dynamicValue(requestUuid, "_notifyUrl");
var bodystr = "result: [ " + result_str + " ]";
result_str = notify_stub(notefyUrl, bodystr);
return result_str;
}
var dynamicValue = function(requestUuid,param){
return new DynamicValue('com.luckymarmot.RequestURLParamDynamicValue', {
request: requestUuid,
param: param
}).getEvaluatedString();
}
function execute_callback(url){
const http_request = new NetworkHTTPRequest();
http_request.requestUrl = url;
http_request.requestMethod = "GET";
http_request.requestTimeout = 10000;
http_request.setRequestHeader("Content-Type", "text/plain text; charset=utf-8");
// http_request.requestBody = requestBodyStr;
http_request.send();
return http_request.responseBody;
};
function notify_stub(url, bodystr){
const http_request = new NetworkHTTPRequest();
http_request.requestUrl = url;
http_request.requestMethod = "POST";
http_request.requestTimeout = 10000;
http_request.setRequestHeader("Content-Type", "text/plain text; charset=utf-8");
http_request.requestBody = bodystr;
http_request.send();
return http_request.responseBody;
};
