所以我最近偶然发现了这个用Python处理HTTP请求的很棒的库;在这里找到http://docs.python-requests.org/en/latest/index.html。
我喜欢使用它,但我不知道如何向我的get请求添加头文件。帮助吗?

我有以下简单的代码连接到SSL网页
NSMutableURLRequest *urlRequest=[NSMutableURLRequest requestWithURL:url];
[ NSURLConnection sendSynchronousRequest: urlRequest returningResponse: nil error: &error ];
除非它给出一个错误,如果证书是自签名的一个错误域=NSURLErrorDomain Code=-1202 UserInfo=0xd29930“不受信任的服务器证书”。有没有一种方法来设置它接受连接(就像在浏览器中你可以按accept)或一种方法来绕过它?
我试图使一个WCF服务在basicHttpBinding上使用https。这是我的web.config:
<!-- language: xml -->
<service behaviorConfiguration="MyServices.PingResultServiceBehavior"
name="MyServices.PingResultService">
<endpoint address=""
binding="basicHttpBinding"
bindingConfiguration="defaultBasicHttpBinding"
contract="MyServices.IPingResultService">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex"
binding="mexHttpBinding"
contract="IMetadataExchange" />
</service>
...
<bindings>
<basicHttpBinding>
<binding name="defaultBasicHttpBinding">
<security mode="Transport">
<transport clientCredentialType="None"/>
</security>
</binding>
</basicHttpBinding>
</bindings>
...
<behaviors>
<serviceBehaviors>
<behavior name="MyServices.UpdateServiceBehavior">
<serviceMetadata httpsGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
</behaviors>
我使用WCFStorm连接,它能够正确检索所有元数据,但当我调用实际的方法时,我得到:
提供的URI方案'https'无效;预计“http”。参数 名称:通过
我试图重定向所有不安全的HTTP请求在我的网站(例如http://www.example.com)到HTTPS (https://www.example.com)。我如何在.htaccess文件中做到这一点?
我用的是PHP。
我有以下htaccess代码:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond !{HTTPS} off
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
</IfModule>
我希望我的网站被重定向到https://www。使用HTTPS,并强制执行www。子域名, 但当我访问http://www时。(没有HTTPS),它不会重定向到https://www与HTTPS。
我有一个类,将从https服务器下载文件。当我运行它时,它返回了很多错误。我的证书好像有问题。是否可以忽略客户机-服务器身份验证?如果有,怎么做?

有没有办法检测HTTP或HTTPS,然后强制使用HTTPS与JavaScript?
我有一些检测HTTP或HTTPS的代码,但我不能强迫它使用HTTPS:。
我使用window.location.protocol属性将站点设置为https:然后刷新页面,希望重新加载加载到浏览器中的新的https'ed URL。
if (window.location.protocol != "https:") {
window.location.protocol = "https:";
window.location.reload();
}
在我的情况下,我使用请求库调用贝宝的API通过HTTPS。不幸的是,我从贝宝得到一个错误,贝宝支持无法找出错误是什么或什么原因造成的。他们想让我“请提供整个请求,包括标题”。
我该怎么做呢?
http和https在性能上有什么主要的区别吗?我似乎记得读到过HTTPS的速度是HTTP的五分之一。这对当前的web服务器/浏览器有效吗?如果有,是否有相关白皮书支持?
如何在原则2中设置默认值?
