Question

我有一个示例 JSON 响应，如下所示：

{
"id": 37,
"merchant_id": "39",
"title": "Parker Pens",
"subtitle": null,
"price": 1000,
"description": null,
"images": [],
"image_thumbs": [],
"options": [{
    "code": "color",
    "label": "Color",
    "extra_info": "",
    "values": [{
        "label": "Red",
        "value": "8"
    }, {
        "label": "Yellow",
        "value": "9"
    }, {
        "label": "Pink",
        "value": "10"
    }]
  }, {
    "code": "size",
    "label": "Size",
    "extra_info": "",
    "values": [{
        "label": "Small",
        "value": "4"
    }, {
        "label": "Medium",
        "value": "5"
    }, {
        "label": "Large",
        "value": "6"
    }]
}],
"options_available": [{
    "combination": [{
        "code": "color",
        "value": "Red"
    }, {
        "code": "size",
        "value": "Small"
    }]
}, {
    "combination": [{
        "code": "color",
        "value": "Red"
    }, {
        "code": "size",
        "value": "Medium"
    }]
}, {
    "combination": [{
        "code": "color",
        "value": "Red"
    }, {
        "code": "size",
        "value": "Large"
    }]
}, {
    "combination": [{
        "code": "color",
        "value": "Yellow"
    }, {
        "code": "size",
        "value": "Small"
    }]
}, {
    "combination": [{
        "code": "color",
        "value": "Yellow"
    }, {
        "code": "size",
        "value": "Medium"
    }]
}, {
    "combination": [{
        "code": "color",
        "value": "Yellow"
    }, {
        "code": "size",
        "value": "Large"
    }]
}, {
    "combination": [{
        "code": "color",
        "value": "Pink"
    }, {
        "code": "size",
        "value": "Small"
    }]
}, {
    "combination": [{
        "code": "color",
        "value": "Pink"
    }, {
        "code": "size",
        "value": "Medium"
    }]
}, {
    "combination": [{
        "code": "color",
        "value": "Pink"
    }, {
        "code": "size",
        "value": "Large"
    }]
}],
"custom_options": []
}

我的采样器为

import org.json.JSONObject;
import org.json.JSONArray;

String response= prev.getResponseDataAsString();
JSONObject jsonObject = new JSONObject(response);
JSONArray jsonArray = jsonObject.getJSONArray("options");
Integer count= jsonArray.length();
vars.put('counts', count);

但是在运行脚本时我收到错误： No signature of method: org.apache.jmeter.threads.JMeterVariables.put() is applicable for argument types: (java.lang.String, java.lang.Integer)

除了值之外（计数=2）。我的目的是获取“Options”键中的数组计数（参见上面的响应）

Answer 1

vars.put不支持与常规值不同的值String，并且您正在尝试输入Integer值。

通过简单的转换即可轻松解决：

vars.put("counts", Integer.toString(count));

另一个选项是使用vars.putObject保存对象

vars.putObject("counts", count);

根据 JMeter最佳实践，还可以转向 JSR223 Sampler ：

从 JMeter 3.1 开始，我们建议从 BeanShell 切换到 JSR223 测试元素
