【问题描述】：

简而言之：我有一个 json 响应，我需要从中提取一些参数。（使用jmeter，正则表达式提取器）

json 响应：

鉴于我总是知道代码，我需要提取 docId、id、nameId。

假设我有一个代码为 OBJ_815895 的对象。这是我迄今为止尝试过的（正则表达式）：

"valId":null,"oclOclIdIndexType":null,"yearno":null,"docId":(.+?),"iconCls":null,"versionNo":1,"parentId":null,"id":"(.+?)","nameId":"(.+?)","name":".+?","menesiai":null,"ivedimas":null,"rowTypeIndex":1,"duomensTipas":null,"y":null,"m1":null,"m2":null,"m3":null,"m4":null,"m5":null,"m6":null,"m7":null,"m8":null,"m9":null,"m10":null,"m11":null,"m12":null,"yo":null,"m1o":null,"m2o":null,"m3o":null,"m4o":null,"m5o":null,"m6o":null,"m7o":null,"m8o":null,"m9o":null,"m10o":null,"m11o":null,"m12o":null,"avg":null,"editable":null,"isParent":true,"locked":false,"lockMsg":null,"icontype":"OBT_364","leaf":null,"dptname":null,"dpt_dpt_id":null,"is_all_dpt_data":null,"attId":null,"code":"OBJ_815895"

起初我认为这是有效的，当我提取列表中的第一个对象时……我承认我对正则表达式不太擅长，如果你能给我任何建议，我将不胜感激。

[答案]：

创建正则表达式提取器：

正则表达式提取器 [代码]

**Reference Name** : code
**Regular Expression** : "code":"(.+?)"
**Template** : $1$
**Match No.** : -1

正则表达式提取器 [docId]

**Reference Name** : docId
**Regular Expression** : "docId":(\d+)
**Template** : $1$
**Match No.** : -1

添加了 groovy 脚本来设置参数：

for(int i = 1; i<vars.get("code_matchNr");i++){
    if(vars.get("code_"+i) == vars.get("objectId")){
        vars.put("docId",vars.get("docId_"+i));
        vars.put("id",vars.get("id_"+i));
        vars.put("nameId",vars.get("nameId_"+i));
    }
}

【问题讨论】：

标签： regex json jmeter

【解决方案1】：

添加Regular Expression Extractors，一个例子：

参考名称：DocId
正则表达式："docId":"(.*?)"
模板： $1$
比赛编号：-1

因为匹配号为负数：

如果匹配数设置为负数，则处理采样器数据中所有可能的匹配。变量设置如下：

refName_matchNr - 找到的匹配数；可能是 0
refName_n，其中 n = 1,2,3 等 - 由模板生成的字符串
refName_n_gm，其中 m=0,1,2 - 匹配 n 的组

当然也提取代码并在附加脚本中按索引匹配它们。

【讨论】：

我想你误解了我的意思。我的 json 响应有多个对象，这些对象又具有参数（docId、nameId 等）。我需要从整个 json 响应中的特定对象中提取 docId。示例：数据[{response_code1},{response_code2},{response_code2}]。例如，我需要从 response_code2 中提取 DocId，知道该响应代码。
我不确定我是否关注你。你所说的，会给我所有可能的 DocId，但我不知道哪个 DocId 属于哪个代码。这就是我需要的，根据代码提取数据。
嗯，这不是我想要的方式，但你的回答给出了我需要的结果。用你的答案编辑了我的问题。
