分享java中模拟浏览器发送https请求报错:Server sent an unsupported extension: type_35
public static String formPost(String url,String params){
String responseMessage = "";
StringBuffer response = new StringBuffer();
HttpURLConnection httpConnection = null;
OutputStreamWriter out = null;
BufferedReader reader = null;
try {
URL urlPost = new URL(url);
httpConnection = (HttpURLConnection) urlPost.openConnection();
httpConnection.setDoOutput(true);
httpConnection.setDoInput(true);
// 参数长度太大，不能用get方式
httpConnection.setRequestMethod("POST");
// 不使用缓存
httpConnection.setUseCaches(false);
// URLConnection.setInstanceFollowRedirects是成员函数，仅作用于当前函数
httpConnection.setInstanceFollowRedirects(true);
httpConnection.setRequestProperty("Connection", "Keep-Alive");
// 设置请求头信息
httpConnection.setRequestProperty("Charset", "UTF-8");
// 设置边界
//httpConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
httpConnection.connect(); ///////这行报错
out = new OutputStreamWriter(httpConnection.getOutputStream(),"UTF-8");
// 构建请求参数
StringBuffer sb = new StringBuffer();
sb.append(params);
out.write(sb.toString());
System.out.println("send_url:" + url);
System.out.println("send_data:" + sb.toString());
// flush and close
out.flush();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (null != out) {
out.close();
}
if (null != reader) {
reader.close();
}
if (null != httpConnection) {
httpConnection.disconnect();
}
} catch (Exception e2) {
e2.printStackTrace();
}
}
try {
reader = new BufferedReader(new InputStreamReader(httpConnection.getInputStream(),"UTF-8"));
while ((responseMessage = reader.readLine()) != null) {
response.append(responseMessage);
response.append("\n");
}
if (!"failure".equals(response.toString())) {
System.out.println("post链接success");
} else {
System.out.println("post链接failue");
}
// 将该url的配置信息缓存起来
return response.toString();
} catch (IOException e) {
e.printStackTrace();
return response.toString();
}
}
用https请求头，随便访问一个网址都不行，http就可以
public static void main(String[] args) {
formPost("https://www.baidu.com", "");
}
发第一次叫我升级jdk的，我已经试了，已经卸载重装升级过jdk了 ，现在是jdk1.8还是报一样的错；
之前都是一直可以用的，做过测试也没问题，忘记改了什么东西之后就没有用了。
下面是报错信息

大佬大佬，我这好久没看自己的帖子了，看你这个解决办法好像是有用的样子，但是这里我应该怎么操作呢?怎么让它允许呢？我小白一个，求大神指点！

解决办法：
编辑Java\jdk1.8.0_151\jre\lib\security\java.security
JRE路径下也有一个 Java\jre1.8.0_151\lib\security\java.security
其中给出了例子,把屏蔽的算法加入进允许的算法中即可，重新启动java程序，如eclipse，tomcat
# Example:
# jdk.tls.legacyAlgorithms=DH_anon, DES_CBC, SSL_RSA_WITH_RC4_128_MD5
#
jdk.tls.legacyAlgorithms= \
K_NULL, C_NULL, M_NULL, \
DHE_DSS_EXPORT, DHE_RSA_EXPORT, DH_anon_EXPORT, DH_DSS_EXPORT, \
DH_RSA_EXPORT, RSA_EXPORT, \
DH_anon, ECDH_anon, \
RC4_128, RC4_40, DES_CBC, DES40_CBC, \
3DES_EDE_CBC

又找了一下 jdk8屏蔽了RC4算法
http://www.oracle.com/technetwork/java/javase/8all-relnotes-2226344.htm
8u51： Synopsis: Deprecate RC4 in SunJSSE provider
8u60： Synopsis: Disable RC4 cipher suites

安装jdk8 的jce，下载后，按其中的说明安装
