Parsing a Json response returned to Gatling
提问by user1075958
I am trying to parse a json response returned to gatling by the server.
我正在尝试解析服务器返回给 gatling 的 json 响应。
My response from server is:
我的服务器回复是：
SessionAttribute(
Session(
GetServices,
3491823964710285818-0,
Map(
gatling.http.cache.etagStore -> Map(https://api.xyz.com/services -> ),
gatling.http.cache.lastModifiedStore -> Map(https://api.xyz.com/services -> ),
myresponse -> {
"created":"2014-12-16T22:06:59.149+0000",
"id":"x8utwb2unq8uey23vpj64t65",
"name":"myservice",
"updated":"2014-12-16T22:06:59.149+0000",
"version":null
}),
1418767654142,622,
OK,List(),<function1>),id)
I am doing this in my script:
我在我的脚本中这样做：
val scn = scenario("GetServices")
.exec(http("Get all Services")
.post("/services")
.body(StringBody("""{ "name": "myservice" }""")).asJSON
.headers(sentHeaders)
.check(jsonPath("$")
.saveAs("myresponse"))
).exec(session => {
println(session.get("id"))
session
})
It is still printing the whole response. How can I just retrieve the id which is "x8utwb2unq8uey23vpj64t65"?
它仍在打印整个响应。我怎样才能检索 id 是"x8utwb2unq8uey23vpj64t65"？

It might be easiest to use a little bit more jsonPathto pull out the idyou need, storing thatin its own variable for later use.
Remember that jsonPathis still a CheckBuilder, so you can't just access the result directly - it might have failed to match.
这可能是最容易使用的一点点jsonPath拔出id你的需要，存储的是在自己的供以后使用的变量。请记住，jsonPath它仍然是一个 CheckBuilder，因此您不能直接访问结果 - 它可能无法匹配。
Converting it to an Option[String]seems like a reasonable thing to do though.
不过，将其转换为 anOption[String]似乎是一件合理的事情。
So your final few lines would become:
所以你的最后几行将变成：
...
.check(
jsonPath("$.id").saveAs("myresponseId")
)
)
).exec(session => {
val maybeId = session.get("myresponseId").asOption[String]
println(maybeId.getOrElse("COULD NOT FIND ID"))
session
})
