从gatling CSV feeder传递字符串数组

Question

是否可以将字符串数组从feeder传递到post请求。

我的csv文件：

sourceId,date,keywords,payload
stg_st_record1,"2017-10-10T00:53:42Z",["SAVE_ALL","John","configs"],"Here is some payload1"
stg_st_record2,"2017-10-10T00:53:42Z",["SAVE_ALL","John","configs"],"Here is some payload2"

我的加特林剧本

def PostActionLog():ChainBuilder = {
repeat(times = 10) {
feed(csvPostFeeder)
.exec (http("Post Action logs")
.post("/api/actionlogs")
.body(StringBody("""{"sourceId": "${sourceId}","date": "${date}", "keywords": ${keywords}, 
 "payload": "${payload}" }"""))
.check(status.is(201)))
 }
}

我收到的错误消息：

byteArraysBody={"sourceId": "stg_st_record2","date": "2017-10-10T00:53:42Z", "keywords": 
 ["SAVE_ALL", "payload": "John" }

 HTTP response:
 status=
 415 Unsupported Media Type
 headers= 
 Content-Type: application/json; charset=utf-8
 Date: Wed, 25 Mar 2020 17:05:24 GMT
 Server: Kestrel
 Content-Length: 147

看起来Gatling没有正确地接收馈线数据，我猜断点是字符串数组值传递给Gatling post请求的方式，有什么方法可以实现这一点吗？

Answer 1

问题是你的文件格式非常不正确。CSV有一个规范：RFC4180。

1. 如果逗号是分隔符，如果逗号字符在值内，则该值必须用双引号包装。
2. 如果双引号字符在包装值内，则必须使用前面的双引号进行转义。

sourceId,date,keywords,payload
stg_st_record1,"2017-10-10T00:53:42Z","[""SAVE_ALL"",""John"",""configs""]","Here is some payload1"
stg_st_record2,"2017-10-10T00:53:42Z","[""SAVE_ALL"",""John"",""configs""]","Here is some payload2"
