我试图通过HTTPS获取流的内容,但我必须通过HTTP代理.我不想使用cURL,而是使用fopen和context参数.

问题是,我无法通过HTTPS工作(HTTP工作正常).

这DOES NOT工作:

$stream = stream_context_create(Array("http" => Array("method"  => "GET",
                                                      "timeout" => 20,
                                                      "proxy"   => "tcp://my-proxy:3128",
                                                      'request_fulluri' => True 
                                )));
echo file_get_contents('https://my-stream', false, $context); 

这DOES作品(卷曲):

$url = 'https://my-stream';
$proxy = 'my-proxy:3128';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 1);
$curl_scraped_page = curl_exec($ch);
curl_close($ch);

echo $curl_scraped_page;

有人知道第一段代码有什么问题吗？如果它与cURL一起使用,必须有一种方法使它适用于上下文.我试图将上下文选项更改为一堆不同的值,但没有运气.

任何帮助将不胜感激 !

谢谢.

在我的Play 2应用程序中,我在java.net.URL,Bee Client上调用Scala包装器.根据文档,java.net.URL支持代理,但我找不到有关如何以及如何为环境变量设置的详细信息.

我试过,没有成功,

export proxySet=true
export proxyHost=my-proxy-server
export proxyPort=1080

任何帮助都感激不尽.

更新: 在进一步挖掘之后,它们不是环境变量,而是Rick指出的JVM命令行参数.但是,我也试过以下也没有成功

export JAVA_OPTS="$JAVA_OPTS -Dhttp.proxyHost=my-proxy-server -Dhttp.proxyPort=1080"
sbt -Dhttp.proxyHost=my-proxy-server -Dhttp.proxyPort=1080 test

请注意,我将参数传递给sbt test.

我想知道数据包嗅探器的原理.他们如何捕获其他应用程序的数据包？

我一直在考虑这个问题.我有一个理论.这与代理服务器的工作方式有关吗？当使用某些特殊API时,所有本地应用程序都会将其数据包发送到指定的ip而不是原始数据包.数据包嗅探器接收并复制,最后将它们发送回原始目的地.是对的吗？

你能解释一下数据包嗅探器是如何工作的吗？提前谢谢你的帮助.

如果我的服务器使用Cloudflare,我如何获得使用代理的访问者的Real IP？

到目前为止,如果访问者在不使用代理的情况下打开我的服务器(使用cloudflare),这将起作用

isset($_SERVER["HTTP_CF_CONNECTING_IP"]) ? $_SERVER["HTTP_CF_CONNECTING_IP"] : $_SERVER["REMOTE_ADDR"];

我正在尝试在现有的spring项目中配置一个建议.以下配置适用于单个程序包,但是当切入点表达式尝试在所有程序包上应用该通知时,它会给出以下错误.

我的配置:

<aop:config>
    <aop:pointcut id="loggingPointcut" expression="execution(* com.abc.businessprocess.operation..*.execute(..))" />
    <aop:advisor id="methodLoggingAdvisor" advice-ref="methodLoggingAdvice" pointcut-ref="loggingPointcut" />
</aop:config>

我也尝试了注释,但它给出了相同的错误.即使在使用它给出相同的错误后,我也尝试使用CGLIB.

错误:

我有两个服务器:一个用于开发,可以轻松访问WEB,另一个用于生产,只能使用代理访问WEB.

我想从我的生产服务器调用SOAP WEB服务.

以下是代码(URL是假的):

$url = 'https://www.webservice.com/soap.php';
$wsdl = 'https://www.webservice.com/soap.php?wsdl';

$client = new SoapClient
(
        $wsdl,
        array
        (
                'location'      => $url,
                'proxy_host'    => 'www.myproxy.com',
                'proxy_port'    => 8080,
        )
);


$namespace = 'urn:mynamespace';
$header = array
(
        'header1' => 'H1',
        'header2' => 'H2',
        'header3' => 'H3',
);

$client->__setSoapHeaders(new SoapHeader($namespace, 'myHeader', $header));

$params = array
(
        'param1' => 'val1',
        'param2' => 'val2',
        'param3' => 'val3',
);

$result = $client->method($params);

我从我的开发服务器运行它,我得到了预期的结果.现在我从我的生产服务器运行它,我得到:

PHP Warning:  SoapClient::SoapClient(https://www.webservice.com/soap.php?wsdl): failed to open stream: HTTP request failed! HTTP/1.1 400 …

嗨，我有这个课要测试：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations={"/service.xml"})
public class Test {

    @Autowired private CommonService commonService;

调试时，我在CommonService上获得一个对象，该对象的属性为SdkDynamicAopProxy。

如何在我的属性commonService上获得一个CommonServiceImp对象？

commonService

public interface CommonService {...}

CommonServiceImp

@Service("commonService")
@Transactional("transactionManager")
public class CommonServiceImp implements CommonService {
    @Autowired private CommonDaoJdbcImp commonDao; ...}

我的tomcat在8080上运行

apache在80上运行

我实现了

<Location />
    ProxyPass ajp://localhost:8080/ retry=0 timeout=30
    ProxyPassReverse ajp://localhost:8080/
       </Location>

我无法通过apache访问我的java应用程序，并且不断出错

任何建议解决ajp代理错误

我requests在我的脚本中使用模块,我想了解方法中的proxies参数get().这个答案已经发布了以下代码来说明proxies参数的用法:

http_proxy  = "10.10.1.10:3128"
https_proxy = "10.10.1.11:1080"
ftp_proxy   = "10.10.1.10:3128"

proxyDict = {"http":http_proxy,  "https":https_proxy, "ftp":ftp_proxy }

r = requests.get(url, headers=headers, proxies=proxyDict)

这是我的问题:

1. 为什么我们传递多个代理get()？怎么get()用它们？它一个接一个地尝试吗？

2. 有代理人说,a.b.c.d:port我怎么知道它的协议类型？当您从hidemyass.com购买高级代理时,它ip:port仅以格式发送代理,并且不发送协议类型.那么我应该传递给requests.get()方法呢？

我有这些疑虑,因为我对代理一般都不太了解,以及它们是如何工作的.如果有人解释这一点,那将会很棒.

我试图在NetBeans 7.4中设置maven代理,因为我在代理后面.我从工具>选项>常规>代理设置中在NetBeans中设置代理,它工作正常.但是当我尝试构建项目时,我仍然遇到错误.

Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5: Could not transfer artifact org.apache.maven.plugins:maven-resources-plugin:pom:2.5 from/to central (http://repo.maven.apache.org/maven2): repo.maven.apache.org: Unknown host repo.maven.apache.org -> [Help 1]

我搜索了错误消息,然后在maven的settings.xml文件中设置了相同的代理,但是再次出现错误.

Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5: Could not transfer artifact org.apache.maven.plugins:maven-resources-plugin:pom:2.5 from/to central (http://repo.maven.apache.org/maven2): Not authorized by proxy , ReasonPhrase:Proxy Authentication Required. -> [Help 1]

有谁知道什么是错的？

添加代理设置:
