正则表达式提取 [Jmeter]

Question

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：

我需要提取 docId、id、nameId，因为我将永远知道代码。

假设我有代码为 OBJ_815895 的对象。这是我到目前为止尝试过的（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"

起初我认为这是可行的，当我提取列表中的第一个对象时，我承认我不太擅长正则表达式，我将不胜感激你能提供的任何建议我.

[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** : $
**Match No.** : -1

正则表达式提取器 [docId]

**Reference Name** : docId
**Regular Expression** : "docId":(\d+)
**Template** : $
**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));
    }
}

Answer 1

添加Regular Expression Extractors，一个例子：

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

因为负匹配号:

如果匹配数设置为负数，则采样器数据中所有可能的匹配都会被处理。变量设置如下：

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

但当然也提取代码并在附加脚本中按索引匹配它们。
