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;

}
