JAVA利用HttpClient进行POST请求(HTTPS).doc

(完整版)JAVA利用HttpClient进行POST请求(HTTPS)JAVA利用HttpClient进行POST请求（HTTPS）分类：java（31）jsp（1）目前，要为另一个项目提供接口，接口是用HTTP URL实现的,最初的想法是另一个项目用jQuerypost进行请求。但是，很可能另一个项目是部署在别的机器上，那么就存在跨域问题，而JQuery的post请求是不允许跨域的。这时，就只能够用HttpClient包进行请求了，同时由于请求的URL是HTTPS的,为了避免需要证书，所以用一个类继承DefaultHttpClient类,忽略校验过程.1。写一个SSLClient类，继承至HttpClientjavaview plaincopy1. importjava.security.cert.CertificateException；2. importjava.security。cert。X509Certificate；3. import。ssl。SSLContext;4. importjavax。net.ssl.TrustManager;5. import.ssl。X509TrustManager；6. importorg.apache。http.conn。ClientConnectionManager；7. importorg.apache.http。conn。scheme。Scheme；8. importorg。apache.http.conn.scheme。SchemeRegistry；9. importorg。apache。http。conn。ssl.SSLSocketFactory;10. importorg.apache.http。impl。client.DefaultHttpClient;11. /用于进行Https请求的HttpClient12. publicclassSSLClientextendsDefaultHttpClient13. publicSSLClient()throwsException14. super（）;15.
