If PostgreSQL is compiled without SSL support, using options require , verify-ca , or verify-full will cause an error, while options allow and prefer will be accepted but libpq will not actually attempt an SSL connection.", "documented": true, "environment": "PGSSLMODE", "default_evidence": [], "compiled_default_expression": "DefaultSSLMode"}, "comparison_hash": "28e56ade1492b805b5b1b0693ba850df9e7e4eefe6c3daab8da1d7a71fa8d533", "manual_language": "zh", "default_evidence": [], "description_zh_html": "<p>\u8fde\u63a5\u53c2\u6570 sslmode\u3002</p><h3>\u540c\u7248\u672c\u4e2d\u6587\u624b\u518c\u5b9a\u4e49</h3><dd><p>\n        \u8fd9\u4e2a\u9009\u9879\u786e\u5b9a\u662f\u5426\u4ee5\u53ca\u4ee5\u4f55\u79cd\u4f18\u5148\u7ea7\u4e0e\u670d\u52a1\u5668\u534f\u5546\u5b89\u5168\u7684 <acronym>SSL</acronym> TCP/IP \u8fde\u63a5\u3002\u6709\u516d\u79cd\u6a21\u5f0f\uff1a\n\n        </p><div><dl><dt><span><code>disable</code></span></dt><dd><p>\n            \u4ec5\u5c1d\u8bd5\u975e <acronym>SSL</acronym> \u8fde\u63a5\n           </p></dd><dt><span><code>allow</code></span></dt><dd><p>\n            \u9996\u5148\u5c1d\u8bd5\u975e <acronym>SSL</acronym> \u8fde\u63a5\uff1b\u5982\u679c\u5931\u8d25\uff0c\u5219\u5c1d\u8bd5 <acronym>SSL</acronym> \u8fde\u63a5\n           </p></dd><dt><span><code>prefer</code>\uff08\u9ed8\u8ba4\uff09</span></dt><dd><p>\n            \u9996\u5148\u5c1d\u8bd5 <acronym>SSL</acronym> \u8fde\u63a5\uff1b\u5982\u679c\u5931\u8d25\uff0c\u5219\u5c1d\u8bd5\u975e <acronym>SSL</acronym> \u8fde\u63a5\n           </p></dd><dt><span><code>require</code></span></dt><dd><p>\n            \u4ec5\u5c1d\u8bd5 <acronym>SSL</acronym> \u8fde\u63a5\u3002\u5982\u679c\u5b58\u5728\u6839 CA \u6587\u4ef6\uff0c\u5219\u9a8c\u8bc1\u8bc1\u4e66\u7684\u65b9\u5f0f\u4e0e\u6307\u5b9a\u4e86 <code>verify-ca</code> \u65f6\u76f8\u540c\n           </p></dd><dt><span><code>verify-ca</code></span></dt><dd><p>\n            \u4ec5\u5c1d\u8bd5 <acronym>SSL</acronym> \u8fde\u63a5\uff0c\u5e76\u9a8c\u8bc1\u670d\u52a1\u5668\u8bc1\u4e66\u662f\u5426\u7531\u53d7\u4fe1\u4efb\u7684\u8bc1\u4e66\u9881\u53d1\u673a\u6784\uff08<acronym>CA</acronym>\uff09\u9881\u53d1\n           </p></dd><dt><span><code>verify-full</code></span></dt><dd><p>\n            \u4ec5\u5c1d\u8bd5 <acronym>SSL</acronym> \u8fde\u63a5\uff0c\u9a8c\u8bc1\u670d\u52a1\u5668\u8bc1\u4e66\u662f\u5426\u7531\u53d7\u4fe1\u4efb\u7684 <acronym>CA</acronym> \u9881\u53d1\uff0c\u5e76\u4e14\u8bf7\u6c42\u7684\u670d\u52a1\u5668\u4e3b\u673a\u540d\u4e0e\u8bc1\u4e66\u4e2d\u7684\u5339\u914d\n           </p></dd></dl></div><p>\n\n        \u8be6\u7ec6\u4e86\u89e3\u8fd9\u4e9b\u9009\u9879\u5982\u4f55\u5de5\u4f5c\uff0c\u8bf7\u53c2\u9605<a href=\"/zh/docs/11/libpq-ssl.html\" rel=\"nofollow\">\u7b2c\u00a034.18\u00a0\u8282</a>\u3002\n       </p><p>\n        \u5728 Unix \u57df\u5957\u63a5\u5b57\u901a\u4fe1\u4e2d\uff0c<code>sslmode</code> \u4f1a\u88ab\u5ffd\u7565\u3002\u5982\u679c <span>PostgreSQL</span> \u7f16\u8bd1\u65f6\u672a\u542f\u7528 SSL \u652f\u6301\uff0c\u4f7f\u7528\u9009\u9879 <code>require</code>\u3001<code>verify-ca</code> \u6216\n        <code>verify-full</code> \u4f1a\u5bfc\u81f4\u9519\u8bef\uff0c\u800c\u9009\u9879 <code>allow</code> \u548c <code>prefer</code>\n        \u5c06\u88ab\u63a5\u53d7\uff0c\u4f46 <span>libpq</span> \u5b9e\u9645\u4e0a\u4e0d\u4f1a\u5c1d\u8bd5\u5efa\u7acb <acronym>SSL</acronym>\n        \u8fde\u63a5\u3002\n</p></dd><p><a href=\"/zh/docs/11/libpq.html#LIBPQ-CONNECT-SSLMODE\" rel=\"nofollow\">\u67e5\u770b\u5b8c\u6574\u4e2d\u6587\u624b\u518c\u4e0e\u4e0a\u4e0b\u6587</a>\u3002</p>", "precedence_evidence": ["The following environment variables can be used to select default connection parameter values, which will be used by PQconnectdb , PQsetdbLogin and PQsetdb if no value is directly specified by the calling code.

If a root CA file is present, verify the certificate in the same way as if verify-ca was specified verify-ca only try an SSL connection, and verify that the server certificate is issued by a trusted certificate authority ( CA ) verify-full only try an SSL connection, verify that the server certificate is issued by a trusted CA and that the requested server host name matches that in the certificate See Section 33.18 for a detailed description of how these options work. sslmode is ignored for Unix domain socket communication.

If PostgreSQL is compiled without SSL support, using options require , verify-ca , or verify-full will cause an error, while options allow and prefer will be accepted but libpq will not actually attempt an SSL connection.

If the same service name exists in both the user and the system file, the user file takes precedence. By default, the per-user service file is named ~/.pg_service.conf . On Microsoft Windows, it is named %APPDATA%\\postgresql\\.pg_service.conf (where %APPDATA% refers to the Application Data subdirectory in the user's profile). A different file name can be specified by setting the environment variable PGSERVICEFILE . The system-wide file is named pg_service.conf . By default it is sought in the etc directory of the PostgreSQL installation (use pg_config --sysconfdir to identify this directory precisely). Another directory, but not a different file name, can be specified by setting the environment variable PGSYSCONFDIR .", "Connection parameters obtained from a service file are combined with parameters obtained from other sources. A service file setting overrides the corresponding environment variable, and in turn can be overridden by a value given directly in the connection string.

To force use of SSL encryption in an environment that has working GSSAPI infrastructure (such as a Kerberos server), also set gssencmode to disable .", "documented": true, "environment": "PGSSLMODE", "default_evidence": [], "compiled_default_expression": "DefaultSSLMode"}, "comparison_hash": "8cee88b057502e1ab1559e9a8b0b8bdc555df07335cf7edfdd1c462963812a19", "manual_language": "zh", "default_evidence": [], "description_zh_html": "<p>\u8fde\u63a5\u53c2\u6570 sslmode\u3002</p><h3>\u540c\u7248\u672c\u4e2d\u6587\u624b\u518c\u5b9a\u4e49</h3><dd><p>\n        \u8fd9\u4e2a\u9009\u9879\u786e\u5b9a\u662f\u5426\u4ee5\u53ca\u4ee5\u4f55\u79cd\u4f18\u5148\u7ea7\u4e0e\u670d\u52a1\u5668\u534f\u5546\u5b89\u5168\u7684 <acronym>SSL</acronym> TCP/IP \u8fde\u63a5\u3002\u6709\u516d\u79cd\u6a21\u5f0f\uff1a\n\n        </p><div><dl><dt><span><code>disable</code></span> </dt><dd><p>\n            \u4ec5\u5c1d\u8bd5\u975e <acronym>SSL</acronym> \u8fde\u63a5\n           </p></dd><dt><span><code>allow</code></span> </dt><dd><p>\n            \u9996\u5148\u5c1d\u8bd5\u975e <acronym>SSL</acronym> \u8fde\u63a5\uff1b\u5982\u679c\u5931\u8d25\uff0c\u5219\u5c1d\u8bd5 <acronym>SSL</acronym> \u8fde\u63a5\n           </p></dd><dt><span><code>prefer</code>\uff08\u9ed8\u8ba4\uff09</span></dt><dd><p>\n            \u9996\u5148\u5c1d\u8bd5 <acronym>SSL</acronym> \u8fde\u63a5\uff1b\u5982\u679c\u5931\u8d25\uff0c\u5219\u5c1d\u8bd5\u975e <acronym>SSL</acronym> \u8fde\u63a5\n           </p></dd><dt><span><code>require</code></span> </dt><dd><p>\n            \u4ec5\u5c1d\u8bd5 <acronym>SSL</acronym> \u8fde\u63a5\u3002\u5982\u679c\u5b58\u5728\u6839 CA \u6587\u4ef6\uff0c\u5219\u9a8c\u8bc1\u8bc1\u4e66\u7684\u65b9\u5f0f\u4e0e\u6307\u5b9a\u4e86 <code>verify-ca</code> \u65f6\u76f8\u540c\n           </p></dd><dt><span><code>verify-ca</code></span> </dt><dd><p>\n            \u4ec5\u5c1d\u8bd5 <acronym>SSL</acronym> \u8fde\u63a5\uff0c\u5e76\u9a8c\u8bc1\u670d\u52a1\u5668\u8bc1\u4e66\u662f\u5426\u7531\u53d7\u4fe1\u4efb\u7684\u8bc1\u4e66\u9881\u53d1\u673a\u6784\uff08<acronym>CA</acronym>\uff09\u9881\u53d1\n           </p></dd><dt><span><code>verify-full</code></span> </dt><dd><p>\n            \u4ec5\u5c1d\u8bd5 <acronym>SSL</acronym> \u8fde\u63a5\uff0c\u9a8c\u8bc1\u670d\u52a1\u5668\u8bc1\u4e66\u662f\u5426\u7531\u53d7\u4fe1\u4efb\u7684 <acronym>CA</acronym> \u9881\u53d1\uff0c\u5e76\u4e14\u8bf7\u6c42\u7684\u670d\u52a1\u5668\u4e3b\u673a\u540d\u4e0e\u8bc1\u4e66\u4e2d\u7684\u5339\u914d\n           </p></dd></dl></div><p>\n\n        \u8be6\u7ec6\u4e86\u89e3\u8fd9\u4e9b\u9009\u9879\u5982\u4f55\u5de5\u4f5c\uff0c\u8bf7\u53c2\u9605<a href=\"/zh/docs/18/libpq-ssl.html\" rel=\"nofollow\">\u7b2c\u00a032.19\u00a0\u8282</a>\u3002\n       </p><p>\n        \u5728 Unix \u57df\u5957\u63a5\u5b57\u901a\u4fe1\u4e2d\uff0c<code>sslmode</code> \u4f1a\u88ab\u5ffd\u7565\u3002\u5982\u679c <span>PostgreSQL</span> \u7f16\u8bd1\u65f6\u672a\u542f\u7528 SSL \u652f\u6301\uff0c\u4f7f\u7528\u9009\u9879 <code>require</code>\u3001<code>verify-ca</code> \u6216\n        <code>verify-full</code> \u4f1a\u5bfc\u81f4\u9519\u8bef\uff0c\u800c\u9009\u9879 <code>allow</code> \u548c <code>prefer</code>\n        \u5c06\u88ab\u63a5\u53d7\uff0c\u4f46 <span>libpq</span> \u5b9e\u9645\u4e0a\u4e0d\u4f1a\u5c1d\u8bd5\u5efa\u7acb <acronym>SSL</acronym>\n        \u8fde\u63a5\u3002\n</p><p>\n       \u6ce8\u610f\uff0c\u5982\u679c\u53ef\u4ee5\u4f7f\u7528 <acronym>GSSAPI</acronym> \u52a0\u5bc6\uff0c\u5c31\u4f1a\u4f18\u5148\u4f7f\u7528\u5b83\u800c\u4e0d\u662f <acronym>SSL</acronym> \u52a0\u5bc6\uff0c\u65e0\u8bba <code>sslmode</code> \u7684\u503c\u662f\u4ec0\u4e48\u3002\u5728\u5177\u6709\u53ef\u7528 <acronym>GSSAPI</acronym> \u57fa\u7840\u8bbe\u65bd\uff08\u4f8b\u5982 Kerberos \u670d\u52a1\u5668\uff09\u7684\u73af\u5883\u4e2d\uff0c\u8981\u5f3a\u5236\u4f7f\u7528 <acronym>SSL</acronym> \u52a0\u5bc6\uff0c\u8fd8\u5e94\u5c06 <code>gssencmode</code> \u8bbe\u4e3a <code>disable</code>\u3002\n      </p></dd><p><a href=\"/zh/docs/18/libpq-connect.html#LIBPQ-CONNECT-SSLMODE\" rel=\"nofollow\">\u67e5\u770b\u5b8c\u6574\u4e2d\u6587\u624b\u518c\u4e0e\u4e0a\u4e0b\u6587</a>\u3002</p>", "precedence_evidence": ["The following environment variables can be used to select default connection parameter values, which will be used by PQconnectdb , PQsetdbLogin and PQsetdb if no value is directly specified by the calling code.
