使用BrowserMob-Proxy REST api设置自定义标头 [英] Setting a custom header using BrowserMob-Proxy REST api

问题描述

我在端口9091上运行了一个browsermob代理。我正在尝试使用browsermob-proxy REST API来设置自定义标头。当我通过代理使用Selenium向我的应用程序发出请求时，我看不到我的应用程序控制台中打印的标题。以下是我的代码。请求正文基于此处的文档。我的要求是使用BrowserMob代理API而不是它的Java库用于这个特定的用例。我在下面的代码中做错了什么？

I have a browsermob proxy running on port 9091. I am trying to use browsermob-proxy REST API to set a custom header. When I make a request to my app using Selenium via the proxy, I don't see the header printed in my apps console. Below is my code. The request body is based on documentation here. My requirement is to use BrowserMob proxy API and not its Java library for this particular use case. Anything I am doing wrong in the code below?

 Proxy proxy = new java.net.Proxy(java.net.Proxy.Type.HTTP, new InetSocketAddress("localhost", 9091));

 String bpmUrl = "http://localhost:8787/proxy/9091/interceptor/request";
 Client client = Client.create();
 String requestBody = "request.getMethod().addHeader(\"custom-header\", \"Bananabot/1.0\");";
 WebResource resource = client.resource(bpmUrl);
 resource.type(MediaType.TEXT_PLAIN_TYPE).post(requestBody);

 String url = "http://localhost:8004";
 DesiredCapabilities capabilities = DesiredCapabilities.firefox();
 capabilities.setCapability(CapabilityType.PROXY, proxy);
 WebDriver driver = new FirefoxDriver(capabilities);
 driver.get(url);
 driver.quit();

我尝试了@ Erki的解决方案，我觉得应该可行，但事实并非如此。这里有什么遗漏？

I tried @Erki's solution which I think should work, but its not. Anything missing here?

 String bpmUrl = "http://localhost:8787/proxy/9091/headers";
     Map<String,String> data = new HashMap<String, String>();
     data.put("user-agent","Bananabot");
     ClientConfig cc = new DefaultClientConfig();
     cc.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING, Boolean.TRUE);
     Client client = Client.create(cc);
     WebResource resource = client.resource(bpmUrl);
     resource.type(MediaType.APPLICATION_JSON).accept(MediaType.APPLICATION_JSON).post(ClientResponse.class, data);

找到答案，我试过Java API ，它工作，并注意到浏览器正在按预期使用代理。使用上面的代码，显然浏览器没有使用代理。因此，我使用 org.openqa.selenium.Proxy 而不是使用 java.net.Proxy 。所以我需要的唯一代码更改是我初始化代理的方式，其余部分是相同的。现在工作正常。

Edit 2 Found the answer, I tried Java API, it worked and noticed that the browser is using proxy as expected. With my code above, obviously the browser was not using proxy. So instead of using java.net.Proxy I used org.openqa.selenium.Proxy which worked. So the only code change I needed was the way I initialize the proxy, rest of it is same. This works fine now.

 String PROXY = "localhost:9091";
 Proxy proxy = new Proxy();
 proxy.setHttpProxy(PROXY);

推荐答案

您正在使用与使用BMP相对应的代码在嵌入模式下：

You are using the code that corresponds to using the BMP in embedded mode:

server.addRequestInterceptor(new RequestInterceptor() {
    @Override
    public void process(BrowserMobHttpRequest request, Har har) {
        request.getMethod().removeHeaders("User-Agent");
        request.getMethod().addHeader("User-Agent", "Bananabot/1.0");
    }
});

如果您实际上已在嵌入模式下启动代理服务器，则此代码可以执行此操作我明白，这不是你所做的或有意的。您需要的可能是：

This code would do if you had actually started the proxy server in embedded mode, which, as far as I understand, is not what you have done or have intended to. What you need is probably:

POST / proxy / [port] / headers - 设置和覆盖HTTP请求标头。
例如设置自定义用户代理。有效载荷数据应该是json
编码的标题集（不是url编码的）

POST /proxy/[port]/headers - Set and override HTTP Request headers. For example setting a custom User-Agent. Payload data should be json encoded set of headers (not url-encoded)
