Question

我想使用带有大量的数据。是否可以创建无限或几GB的长度使用WireMock输出而不分配具有该大小的字节数组或String？

据我所见ResponseDefinitionBuilder has three withBody* methods：

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

我尝试过withBodyFile("/dev/zero")，但遇到以下异常：

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 com.github.tomakehurst.wiremock.common.AbstractFileSource.getBinaryFileNamed(AbstractFileSource.java:45)

    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。

我也检查了Fault enum，但它似乎不可扩展。

您看到文件安全性错误的原因是WireMock仅会读取其配置的文件根目录下的文件，因此设置符号链接可能会起作用。

如果不这样做，仅创建一个很大的文件就可以解决问题，并且在流式处理正文文件时不会占用大量内存。

WireMock产生巨大或无限的响应
