使用HTTPClient進行操作,可以忽略SSL

使用URLConnection讀取數據,訪問HTTPS貌似有問題

做個代碼記錄 Maven引用

<dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpclient</artifactId><version>4.4</version> </dependency> <dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpcore</artifactId><version>4.4</version> </dependency> <dependency><groupId>org.apache.httpcomponents</groupId><artifactId>httpcore-nio</artifactId><version>4.4</version> </dependency>
