如何將Stringbody中的json字符串與Gatling中的動態值一起傳遞？

我必須通過此字符串StringBody我加特林要求如何將Stringbody中的json字符串與Gatling中的動態值一起傳遞？

{"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-context\": {\r\n \"value\": \".\",\r\n \"isExpression\": false\r\n },\r\n \"vfs-location\": {\r\n \"protocol\": \"FILE\",\r\n \"port\": 0,\r\n \"path\": \"/fx/fx-enterprise/storage/media/Training Outbound-FILE\"\r\n }", "Copy 2-json-metadata-instance":" {\r\n \"external-resource\": {\r\n \"id\": 48218841,\r\n \"name\": \"Training Outbound-File\",\r\n \"type\": \"resource\"\r\n },\r\n \"asset-context\": {\r\n \"value\": \".\",\r\n \"isExpression\": false\r\n },\r\n \"vfs-location\": {\r\n \"protocol\": \"FTP\",\r\n \"hostname\": \"ntvt.upload.llnw.net\",\r\n \"port\": 0,\r\n \"path\": \"/poc/V5Dev/R1\",\r\n \"username\": \"ntvt-ht-nt-staging\",\r\n \"password\": \"jpc6t8\"\r\n }"} }}}

這裏是我的斯卡拉腳本

// Dynamic Json values 
    val filePath = System.getProperty("filePath", "/fx/fx-enterprise/storage/media/Training Outbound-FILE") 
    val ftpHostname = System.getProperty("ftpHostname", "ntvt.upload.llnw.net") 
    val ftpUsername = System.getProperty("ftpUsername", "ntvt-ht-nt-staging") 
    val ftpPassword = System.getProperty("ftpPassword", "jpc6t8") 
    val ftpPath = System.getProperty("ftpPath", "/poc/V5Dev/R1") 
    val UUID = System.getProperty("UUID", "b71awerv-4946-4bwe-8eqa-2412fgh98002") 
    val definitionId = System.getProperty("definitionId", "48924212") 

    val scn = scenario("Launch") 
      .exec(http("Wf") 
      .post("""/api/workflows""") 
      .headers(headers_0) 
    // Modification-1 
     .body(StringBody(s"""{"definitionId":"${definitionId}", "stringVariables" : { "Copy 1-json-metadata-instance":" {\r\n \"external-resource\": {\r\n \"id\": 488841,\r\n \"name\": \"Training Outbound-File\",\r\n \"type\": \"resource\"\r\n },\r\n \"asset-context\": {\r\n \"value\": \".\",\r\n \"isExpression\": false\r\n },\r\n \"vfs-location\": {\r\n \"protocol\": \"FILE\",\r\n \"port\": 0,\r\n \"path\": \"${filePath}\"\r\n }", "Copy 2-json-metadata-instance":" {\r\n \"external-resource\": {\r\n \"id\": 488841,\r\n \"name\": \"Training Outbound-File\",\r\n \"type\": \"resource\"\r\n },\r\n \"asset-context\": {\r\n \"value\": \".\",\r\n \"isExpression\": false\r\n },\r\n \"vfs-location\": {\r\n \"protocol\": \"FTP\",\r\n \"hostname\": \"${ftpHostname}\",\r\n \"port\": 0,\r\n \"path\": \"${ftpPath}\",\r\n \"username\": \"${ftpUsername}\",\r\n \"password\": \"${ftpPassword}\"\r\n }"} } }}""")).asJSON) 

    //Modification-2 
     // .body(StringBody(s"""{"definitionId":"$definitionId", "stringVariables" : { "Copy 1-json-metadata-instance":" {"external-resource": {"id": 488841,"name": "Training Outbound-File", "type": "resource"},"asset-context": {"value": ".","isExpression": false},"vfs-location": {"protocol": "FILE","port": 0,"path": "$filePath"}", "Copy 2-json-metadata-instance":" {"external-resource": {"id": 488841,"name": "Training Outbound-File","type": "resource"},"asset-context": {"value": ".","isExpression": false},"vfs-location": {"protocol": "FTP","hostname": "$ftpHostname","port": 0,"path": "$ftpPath","username": "$ftpUsername","password": "$ftpPassword"}"} } }}"""))) 

    setUp(scn.inject(atOnceUsers(userCount))).protocols(httpProtocol)

它的工作原理，如果我通過，因爲它是沒有動態值原始字符串）下方拋出錯誤：

====輸出當你在斯卡拉任何String前加s你調用一個串插。根據其文檔，您必須刪除所有反斜槓，因爲它們會導致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)

我建議刪除所有「\」也替代「與」

我希望這將有助於

嗨亞歷克斯，我從代碼中刪除所有的「/」和「/ R/N」和「與」同，但‘錯誤更換：在處理請求‘ – Peter

感謝您的回答亞歷克斯錯誤’’。它與\\而不是\ – Peter

我格式化JSON字符串的身體時，發現在JSON對象開始的地方有行情我不確定你的JSON是否有效

刪除\ r \ n並添加了額外的反斜槓\ \（我的意思是使用雙反斜槓\而不是\單反斜槓）
