如何在Stringbody中传递json字符串,并在Gatling中传递动态值?
我必须在我的加特林请求的StringBody中传递这个字符串如何在Stringbody中传递json字符串,并在Gatling中传递动态值?,json,scala,performance-testing,load-testing,gatling,Json,Scala,Performance Testing,Load Testing,Gatling,我必须在我的加特林请求的StringBody中传递这个字符串 {"definitionId":4891544, "stringVariables" : {"Copy 1-json-metadata-instance":" {\r\n \"external-resource\": {\r\n \"id\": 4881561,\r\n \"name\": \"Training Outbound-File\",\r\n \"type\": \"resource\"\r\n },\r\n \"asset

setUp(scn.inject(atOnceUsers(userCount))).protocols(httpProtocol)
如果我按原样传递原始字符串(不带动态值),它会工作)
抛出以下错误:

在Scala中的任何
字符串之前添加s
时,调用字符串插值器。根据其文档,您必须删除所有反斜杠,因为它们会导致InvalidEscapeException
/** The simple string interpolator.
*
* It inserts its arguments between corresponding parts of the string context.
* It also treats standard escape sequences as defined in the Scala specification.
* Here's an example of usage:
* {{{
* val name = "James"
* println(s"Hello, $name") // Hello, James
* }}}
* In this example, the expression $name is replaced with the `toString` of the
* variable `name`.
* The `s` interpolator can take the `toString` of any arbitrary expression within
* a `${}` block, for example:
* {{{
* println(s"1 + 1 = ${1 + 1}")
* }}}
* will print the string `1 + 1 = 2`.
*
* @param `args` The arguments to be inserted into the resulting string.
* @throws IllegalArgumentException
* if the number of `parts` in the enclosing `StringContext` does not exceed
* the number of arguments `arg` by exactly 1.
* @throws StringContext.InvalidEscapeException
* if a `parts` string contains a backslash (`\`) character
* that does not start a valid escape sequence.

def s(args: Any*): String = standardInterpolator(treatEscapes, args)
我建议删除所有“\”
也将“替换为”
我希望这会有所帮助,我格式化了JSON字符串正文,并在JSON对象开始声明的地方找到了引号。请看屏幕截图。我不确定您的JSON是否有效,删除了\r\n并添加了额外的反斜杠\(我的意思是使用双反斜杠\而不是单反斜杠)
嗨,Alex,我已经从代码中删除了所有“/”和“/r/n”,并将“替换为”但相同的“错误”:“处理请求时出错”谢谢Alex的回答。它使用\\而不是\
