json - 如何在 Stringbody 中传递 json 字符串以及 Ga特林中的动态值？

Question

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-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 }"} }}}

这是我的 Scala 脚本

// 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)

如果我传递原始字符串，因为它没有动态值，它就会起作用)抛出以下错误:

我格式化了 JSON 字符串主体，发现 JSON 对象开始声明的地方有引号。看截图。我不确定您的 JSON 是否有效
