腾讯企业邮箱官方api文档很简略还有一些错误和漏洞：
1. 获取token单点登录和获取未读邮件数使用的secret不一致。
此处很容易误解为最初用于获取AccessToken的corpSecret
2.获取未读邮件数这个功能可以被管理员停用，需要开启
停用的时候返回返回 {"errcode":602005,"errmsg":"no privilege to access app"}
3.获取未读邮件数的请求为post请求，官方文档是get
4.如果部署的weblogic之类的中间件可以会出现以下问题，请求的https报错证书不一致
此处的问题主要是后台发起请求的时候weblogic会去做安全校验，
解决办法：1.修改weblogic配置
2. HttpsURLConnection 配合Handler绕开证书校验
3.请求之前信任所有证书
信任证书的方法：
private static void trustALLSSLCertificates(HttpURLConnection con) throws NoSuchAlgorithmException, KeyManagementException {
((HttpsURLConnection) con).setHostnameVerifier(new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
// Ignore Certification
TrustManager ignoreCertificationTrustManger = new X509TrustManager() {
public void checkClientTrusted(X509Certificate certificates[], String authType) throws CertificateException {
}
public void checkServerTrusted(X509Certificate[] ax509certificate, String s) throws CertificateException {
}
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
// Prepare SSL Context
TrustManager[] tm = { ignoreCertificationTrustManger };
SSLContext sslContext = SSLContext.getInstance("SSL");
sslContext.init(null, tm, new java.security.SecureRandom());
// 从上述SSLContext对象中得到SSLSocketFactory对象
SSLSocketFactory ssf = sslContext.getSocketFactory();
((HttpsURLConnection) con).setSSLSocketFactory(ssf);
}
后端请求：
public String httpGetbak(String url) {
BufferedReader in = null;
try {
//com.sun.net.ssl.internal.www.protocol.https.Handler
URL realUrl = new URL(null,url,new sun.net.www.protocol.https.Handler());
HttpsURLConnection connection = (HttpsURLConnection) realUrl.openConnection();
trustALLSSLCertificates(connection);
connection.setRequestProperty("accept", "*/*");
connection.setRequestProperty("connection", "Keep-Alive");
connection.setRequestProperty("user-agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1;SV1)");
connection.setConnectTimeout(5000);
connection.setReadTimeout(5000);
connection.connect();
in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
StringBuffer sb = new StringBuffer();
String line;
while ((line = in.readLine()) != null) {
sb.append(line);
}
return sb.toString();
} catch (Exception e) {
e.printStackTrace();
}
finally {
try {
if (in != null) {
in.close();
}
} catch (Exception e2) {
e2.printStackTrace();
}
}
return null;
}
