Scala 关贸总协定中的邮政请求

我在发布pdf文件时遇到了一个问题。在Gatling 2.1.7中录制了一个HAR文件后，我得到了以下信息：

.exec(http("request_10")
        .post("/api/data/files?revisionId=e9af2c93-d8df-4424-b307-df4c4abbaad1&uploadType=read_only_file&fileType=application%2Fpdf&fileName=testdocument.pdf&fileSize=10080&copyToEditable=true")
        .headers(Map(
            "Accept-Encoding" -> "gzip, deflate",
            "Content-Type" -> "multipart/form-data; boundary=----WebKitFormBoundaryawCJ4mjL1imiO7Ye"
            "Origin" -> url))
        .body(RawFileBody("RecordedSimulation_0010_request.txt")))

内容为

RecordedSimulation\u 0010\u request.txt

：

当我尝试回放时，这不起作用（可能是由于唯一的ID），因此（在Bodys文件夹中粘贴

testdocument.pdf

后），我执行了以下操作：

val documentFeeder = Iterator.continually(Map(
        "documentBoundary" -> (Random.alphanumeric.take(16).mkString),
        "documentUuid" -> ((Random.alphanumeric.take(8).mkString + "-" +
                           Random.alphanumeric.take(4).mkString + "-" + 
                           Random.alphanumeric.take(4).mkString + "-" +
                           Random.alphanumeric.take(4).mkString + "-" +
                           Random.alphanumeric.take(12).mkString).toLowerCase)))

...

.feed(documentFeeder)
// a previous exec POST with a check to grab the documentRevisionId

            .post("/api/data/files")

最后，这里是Node.js代码，用于在我们的应用程序中发布虚拟数据（我使用它作为参考，因为我知道它可以工作）：

我花了几天时间解决这个问题，这是我第一次涉足Scala和Gatling。我在这里错过了什么来获得这个职位

一个突出的问题（尽管这可能是一个转移视线的问题）是，我的应用程序在标题中使用了

内容长度

——考虑到盖特林遗漏了它，这是否有必要？如果有必要，我是否能够在不硬编码的情况下将数字插入Gatling

编辑

读完这篇文章后，我尝试了以下方法：

val documentFeeder = Iterator.continually(Map(
        "documentBoundary" -> (Random.alphanumeric.take(16).mkString),
        "documentUuid" -> ((Random.alphanumeric.take(8).mkString + "-" +
                           Random.alphanumeric.take(4).mkString + "-" + 
                           Random.alphanumeric.take(4).mkString + "-" +
                           Random.alphanumeric.take(4).mkString + "-" +
                           Random.alphanumeric.take(12).mkString).toLowerCase)))

但我仍然没有成功。有什么关于前进的建议吗？

如果这对其他人有帮助的话，我正试图设置一个自定义边界，而盖特林已经这样做了。以下是解决我问题的方法：

.exec(http("Post document: upload the file")
            .post("/api/data/files?revisionId=${documentRevisionId}&uploadType=read_only_file&fileType=application%2Fpdf&fileName=testdocument.pdf&fileSize=10080&copyToEditable=true") // ensure testdocument.pdf is in user-files/bodies
            .headers(Headers.headers_6)
            .formParamMap(Map(
                "resumableChunkNumber" -> "1",
                "resumableChunkSize" -> "1048576",
                "resumableCurrentChunkSize" -> "10080",
                "resumableTotalSize" -> "10080",
                "resumableType" -> "application/pdf",
                "resumableIdentifier" -> "${documentUuid}",
                "resumableFilename" -> "testdocument.pdf",
                "resumableRelativePath" -> "testdocument.pdf",
                "resumableTotalChunks" -> "1"))
            .bodyPart(RawFileBodyPart("file", "testdocument.pdf")
                .fileName("testdocument.pdf")
                .transferEncoding("binary")).asMultipartForm)

---

虽然@Chuck的答案是正确的，但最简单的代码应该是

  http("Create contentV2")
    .post("/some/path")
    .header("Content-Type", "multipart/form-data")
    .bodyPart(StringBodyPart("changeRequest", changeRequest)).asMultipartForm
    .bodyPart(StringBodyPart("payload", ElFileBody(filename))).asMultipartForm
    .check(status is 201)

现在我们可以用多种东西代替StringBodyPart，如RawFileBodyPart、ByteArrayBodyPart等。更多信息
