我想在Jmeter中使用GraphQL HTTP请求发送以下请求-

{"pageName":"TEST_SCREEN","section":"TEST_SCREEN","action":{"name":"includeObjects","fields":[{"fieldName":"id_","value":"101"},{"fieldName":"id_","value":"102"},{"fieldName":"id_","value":"103"}]}}

我动态地生成“fields”的值，它可以有任意数量的条目。所以我为字段生成了值，并预先存储在一个变量中，如下所示：

String request = "[";
for (int i = 0 ;i<items.length;i++) {
    if (!"[".equals(request)) {
        request +=",";
    }   
    request += "{\"fieldName\":\"id_\",\"value\":\""+items[i]+"\"}";
}
request += "]";
vars.put("ITEMS_ID_REQUEST",request);

然后在graphQL示例中，在变量下我这样给出-

{"pageName":"NEW_PAGE","section":"NEW_FILTER_PAGE","action":{"name":"includeAction","fields":"${ITEMS_ID_REQUEST}"}}

JMeter正在发送以下reuest-

{"pageName":"TEST_SCREEN","section":"TEST_SCREEN","action":{"name":"includeObjects","fields":"[{"fieldName":"id_","value":"54794"},{"fieldName":"id_","value":"54795"},{"fieldName":"id_","value":"54796"},{"fieldName":"id_","value":"54797"},{"fieldName":"id_","value":"54798"}]"}}

我的样本不合格。我注意到应该是[{..}]的字段的值现在被括在双引号中，这会扰乱JSON请求。我知道我们必须把JMeter变量用双引号括起来，所以删除它们不起作用，所以我试图转义双引号，但这也不起作用。如何在没有双引号的情况下正确替换所需的值？提前感谢！
