利用HttpClient 4.5实现http与https请求

1、http实现get请求:

首先设置全局的标准cookie策略

RequestConfig config = RequestConfig.custom().setCookieSpec(CookieSpecs.STANDARD_STRICT).build();

设置可关闭的httpclient

CloseableHttpClient httpClient = HttpClients.custom().setDefaultRequestConfig(config).build();

发送get请求

2、http实现post请求:

首先设置全局的标准cookie策略

RequestConfig config = RequestConfig.custom().setCookieSpec(CookieSpecs.STANDARD_STRICT).build();

设置可关闭的httpclient

CloseableHttpClient httpClient = HttpClients.custom().setDefaultRequestConfig(config).build();

对请求参数进行编码后再进行发送

3、https网站一般情况下使用了安全系数较低的SHA-1签名，因此首先我们在调用SSL之前需要重写验证方法，取消检测SSL。

4、https实现get请求:

创建可用Scheme

Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()        .register("http", PlainConnectionSocketFactory.INSTANCE).register("https", socketFactory).build();

创建ConnectionManager，添加Connection配置信息

PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager(socketFactoryRegistry);CloseableHttpClient httpClient = HttpClients.custom().setConnectionManager(connectionManager)        .setDefaultRequestConfig(defaultRequestConfig).build();

发送get请求

5、https实现post请求:

创建可用Scheme

Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()       .register("http", PlainConnectionSocketFactory.INSTANCE).register("https", socketFactory).build();

创建ConnectionManager，添加Connection配置信息

PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager(socketFactoryRegistry);CloseableHttpClient httpClient = HttpClients.custom().setConnectionManager(connectionManager)       .setDefaultRequestConfig(defaultRequestConfig).build();

对请求参数进行编码后再进行发送
