与WireMock巨大或无限响应

Question

我想使用的HTTP客户端与一个巨大的数据量来测试我们的应用程序。是否有可能不分配一个字节数组或字符串与尺寸以产生具有WireMock无限或几千兆字节长度的输出？

据我看到ResponseDefinitionBuilder has three withBody* methods：

• public ResponseDefinitionBuilder withBodyFile(String fileName)
• public ResponseDefinitionBuilder withBody(String body)
• public ResponseDefinitionBuilder withBody(byte[] body)

我曾尝试withBodyFile("/dev/zero")但我得到以下异常：

WARN (ServletHandler.java:628) - /test.txt
com.github.tomakehurst.wiremock.security.NotAuthorisedException: Access to file /dev/zero is not permitted
    at com.github.tomakehurst.wiremock.common.AbstractFileSource.assertFilePathIsUnderRoot(AbstractFileSource.java:160)

    at javax.servlet.http.HttpServlet.service(HttpServlet.java:790)
    ...

另外两个需要巨大的内存数组或字符串，我也想避免的。

我还检查了Fault enum，但它似乎并没有延长。

你看到了文件的安全性错误的原因是，WireMock将只读取它的配置文件根目录下的文件，所以建立一个符号可能会奏效。

如果做不到这一点，只是创造一个非常大的文件会做的伎俩，和身体的文件流不会消耗大量的内存。
