httpClient发送 返回报文乱码,返回的报文确实为utf-8，然而用
HttpEntity entity = response.getEntity();
String retule=EntityUtils.toString(entity, "UTF-8");
指定实体的编码返回的报文还是乱码。
解决办法---------------
①：
HttpEntity entity = response.getEntity()
InputStream is =entity.getContent();
用输出流接收is中的内容就行了，这样的话第三方放回什么内容，此处就会接收到什么内容，不会出现乱码的问题。
②：
使用String类的构造方法进行编码转换
String temp=EntityUtils.toString(entity, "UTF-8");
String result=new String(temp.getBytes("ISO-8859-1"),"utf-8")。
public static String sendSSLPostRequest_unitedB2C(String reqURL,
Map<String, String> params) {
String responseContent = null; // 响应内容
HttpClient httpClient = new DefaultHttpClient(); // 创建默认的httpClient实例
X509TrustManager xtm = new X509TrustManager() { // 创建TrustManager
public void checkClientTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] chain,
String authType) throws CertificateException {
}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
try {
// TLS1.0与SSL3.0基本上没有太大的差别，可粗略理解为TLS是SSL的继承者，但它们使用的是相同的SSLContext
SSLContext ctx = SSLContext.getInstance("TLS");
// 使用TrustManager来初始化该上下文，TrustManager只是被SSL的Socket所使用
ctx.init(null, new TrustManager[] { xtm }, null);
// 创建SSLSocketFactory
SSLSocketFactory socketFactory = new SSLSocketFactory(ctx);
// 通过SchemeRegistry将SSLSocketFactory注册到我们的HttpClient上
httpClient.getConnectionManager().getSchemeRegistry()
.register(new Scheme("https", 443, socketFactory));
