Wiremock - 通过转发代理记录/播放答案

【问题标题】：Wiremock - Record/Playback via forward proxyWiremock - 通过转发代理记录/播放

【问题描述】：

我正在尝试使用 wiremock（目前是独立的）来记录/播放对外部 SaaS 系统发出的所有请求。但是，我正在尝试通过需要代理所有请求的公司网络。

真正的要求是：

curl -v -k --proxy "mycompany.proxy:81111" "https://api.thirdparty.com/api/v1/soap?wsdl"

返回结果

从 Wiremock 文档中，我尝试了以下配置：

java -jar wiremock-standalone-2.21.0.jar --https-port 443 --record-mappings --proxy-all="https://api.thirdparty.com" --preserve-host-header --proxy-via="http://mycompany.proxy:81111" --verbose --print-all-network-traffic

但是，使用 Wiremock 时，我似乎无法得到相同的响应。

如果我尝试通过 HTTPS 访问 Wiremock...

curl -v -k "https://localhost:443/api/v1/soap?wsdl"

如果，我尝试使用 http 访问wiremock...

$ curl -v -k "http://localhost:8080/api/v1/soap?wsdl"

非常感谢任何帮助。

【解决方案1】：

根据Wiremock documentation，您可以通过代理（但不能通过 JSON）以编程方式设置目标 API。

通过另一个代理服务器代理

如果您所在的网络只允许 HTTP 流量传出到通过不透明代理上网，您可能希望设置代理映射该路由通过此服务器。这可以通过编程方式配置将配置对象传递给 WireMockServer 的构造函数或 JUnit 规则如下：

WireMockServer wireMockServer = new WireMockServer(options()
    .proxyVia("proxy.mycorp.com", 8080)
);
