Question

我已经解析了json响应并使用.findAll（）保存了它。我想要做的是，如果值为＆＃39; -1＆＃39;则忽略keyframeId。否则将keyframeId放入带有循环的.get（）请求中。我做了一些代码但是没有在get（）请求中设置值并给出了“KO”。这里它采用Vector中的所有值并将所有值放在单个http调用中查看错误以获取详细信息。我也不确定doIf条件。你能帮忙吗？谢谢。我的Json响应格式是这样的。

{
totalCount: 1134,
limit: 9,
offset: 0,
resources: [
        {
        title: "Test",
        keyframeId: -1
        }
        {
        title: "Test1",
        keyframeId: 12345
        }
        {
        title: "Test2",
        keyframeId: 12341
        }
        {
        title: "Test3",
        keyframeId: -1
        }
        {
        title: "Test4",
        keyframeId: 135481
        }
        ....
        ....

引发以下错误：

Answer 1

如果我已正确理解您想从响应中获取值，然后在下一个请求中使用它。首先，您必须保存正确的keyframeId。

不清楚的是，您是想从列表中选择一个随机keyframeId还是多个关键帧，我选择了随机选择。

首先，我们必须将一些jsonPath应用于我们的JSON响应。此代码.check(jsonPath("$.resources[?(@.keyframeId > -1)].keyframeId")将仅返回大于-1的keyframeId列表。

接下来，我们选择一个随机的并将其保存到变量。

//  Fetch and save data
.exec(http("Keyframe_request")
  .get(uri1 + "/awsset/browse%3Bresource_type=media%3Boffset=1%3Blimit=9")
  .headers(headers_12)
  .check(jsonPath("$.resources[?(@.keyframeId > -1)].keyframeId")
      .ofType[String]
      .findAll
      .transform(s => util.Random.shuffle(s).apply(1))
      .saveAs("keyframeId"))

现在您只需检查会话变量keyframeId是否存在并使用它来驱动您的响应${keyframeId}

Answer 2

.foreach("${IdList}", "id") {
            doIf(session => session("id").as[String] != "-1") {
            exec(http("ID != -1").get(session => session("id").as[String])
            .check(status.is(404)))}
            }

如何将json响应放入具有条件的循环中？
