两种抓包工具Wireshark和Fiddler
Fidder专门针对HTTP流进行抓包
Wireshark可以抓到各种协议的通讯包。
以USKSA项目为例子，我们可以通过Fiddler工具来抓包，效果如下
录制后，通过分析Header 和Request json，可以达到手写loadrunner脚本的效果，因为网速的状况有时候导致LR录制不到，如此用抓包工具分析手写script不用拘束于用Loadrunner工具来录制，
这些request脚本通过比对，发现跟Loadrunner录制的json格式上基本一样，但是需要调整几个地方
所以如下几个步骤
1，将Request的json数据拷贝到txt文件中，用NodePad++ 工具打开（在此推荐NodePad++工具）通过添加jsonView插件可以调整json格式）
2. 将 单斜杠 替换为 双斜杠 （\ —> \\）
3.将 单引号 替换为 斜杠单引号 （" —> \"）
这样的json格式就符合LR提交的json格式了
如：
"Body={
\"evalItem\":{\"performId\":\"{PerformId}\",\"versionId\":\"USK.MST.2015.13\",\"itemId\":\"DEV0000081\",\"parentId\":\"FU00000015\",\"dataType\":\"Standard\",\"dataLevel\":\"3\",\"answerType\":\"YES_NO\",\"pointValue\":1,\"deductPoint\":0,\"earnPoint\":0,\"priority\":0,\"optional\":false,\"ancestorIds\":\"\\\"SC00000003\\\",\\\"FU00000015\\\"\",\"value0\":\"Y\",\"value1\":\"\",\"value2\":\"\",\"value3\":\"\",\"value4\":0,\"value5\":\"\",\"value6\":\"\",\"value7\":\"\",\"value8\":\"\",\"value9\":\"\",\"value10\":\"\",\"bizLevel\":1,\"bizLevelUpgraded\":1,\"bizLevelMax\":2,\"rptPlatform\":\"\",\"bmu\":\"\",\"concept\":\"\",\"validationType\":\"\",\"validationRule\":\"\",\"valueList\":\"\",\"videoLink\":\"\",\"fsc\":0,\"fsiCode\":\"CL101\",\"displayId\":\"\",\"photo\":true,\"maint\":false,\"detailRequired\":false,\"qualityGuide\":\"RFIL000163\",\"summaryCat\":\"SMCT000003\",\"desc0\":\"Exterior building and all exterior structures are clean.\",\"desc1\":\"\\u25cf No soil on exterior building or other structures (such as fences, retaining walls and decking), windows (sills, frames, seals), doors (frames, handles, thresholds, locks/keypads, closures, hardware), lights (fixtures, functioning), roof (tile, gutters, drains/downspouts), awnings or any element of the building. \\n\\u25cf There should be no dirt buildup, graffiti, mildew, algae, smear marks, streaks or fingerprints. \\n\\nWHY is this important?\\n\\u2022 Poor appearance and condition of the restaurant exterior is shown to have a significant impact on a Guest's decision on whether or not to visit a restaurant.\\n\\u2022 The best way to invite Guests into the restaurant is to impress them with a clean and well-maintained exterior.\",\"desc2\":\"\\u25cf One of anything listed (webs, graffiti, buildup dirt, etc.) is an issue.\\n\\u25cf Allow 2 issues before scoring.\",\"desc3\":\"Allow 2 issues.\\nL1 if 3-4 issues.\\nL2 if >4 issues. \",\"selectionList\":null,\"reoccurring\":2,\"occurredInMR\":true,\"qualityGuides\":[{\"itemId\":\"RFIL000163\",\"desc0\":\"Guest Touch Points job aid\",\"desc1\":\"/ROCC.FILE.2014.01/RFIL000163/RFIL000163_en_US.pdf\",\"displayOrder\":null,\"detailRequired\":false,\"rawValue\":null,\"label\":null,\"path\":null,\"uri\":null}]},\"operationType\":\"answer\"

几种调试json格式的方法：
将URL换成本地URL并且手写Script
做下实验，看看抓包的json经过调试能否正常的通过Loadrunner执行

return 0;

执行后 如下：
以后可以通过设置网络，来抓取IOS平台app的http包从而手写script进行并发。
方式二：（更简单直白的方式）
直接右键将.saz格式的抓包文件转化成 Vugen Script
