小程序开发中在nginx端口同时监听多个域名的方法详解

今天我们来看看小程序开发过程中的常见问题:

1.如何在nginx同一端口同时监听多个域名?

在启用新的域名的时候,只需要另启一个server配置文件,丢在vhosts目录下即可,不会报端口被占,这个维护nginx的大部分人都知道。但是,这里有个地方要注意:不能跨nginx实例。很多同事习惯在同一虚机或者云主机下安装多个nginx实例,如果你在实例1里面用了某个端口,再在实例2里面用这个端口绑不同域名,那对不起了,报错妥妥的出来:

nginx: [emerg] bind() to 0.0.0.0:xxxx failed (98: Address already in use)nginx: [emerg] still could not bind()

个人建议:不在同一台虚机或者云主机下安装多个nginx实例。

2.http和https如何同时监听?

这种需求还是挺多的,有时候我们的证书需要安装在A10或者F5这类硬负载均衡上,此时,DMZ区的服务器不需要安装证书,只需要监听http端口即可。但与此同时,内网dns直接将A地址指到了服务器,此时又需要在服务器上安装证书。这种场景,就需要服务器同时对http和https端口进行监听,监听https口是为了解析内网https域名,监听http口是为了反向代理从DMZ区过来的http请求。如此,可实现内外网https域名统一。

最常见的配置如下

server {

listen8080;

listen443 ssl;

server_namexxx.xxx.cn;;

ssl_certificatessl/server.pem;

ssl_certificate_keyssl/server.key;

......

}

3.中文转码的MD5加密的常见方法var rotateLeft = function(lValue, iShiftBits) {return(lValue << iShiftBits) | (lValue >>> (32 - iShiftBits));}var addUnsigned = function(lX, lY) {var lX4, lY4, lX8, lY8, lResult;lX8 = (lX & 0x80000000);lY8 = (lY & 0x80000000);lX4 = (lX & 0x40000000);lY4 = (lY & 0x40000000);lResult = (lX & 0x3FFFFFFF) + (lY & 0x3FFFFFFF);if(lX4 & lY4) return(lResult ^ 0x80000000 ^ lX8 ^ lY8);if(lX4 | lY4) {if(lResult & 0x40000000) return(lResult ^ 0xC0000000 ^ lX8 ^ lY8);else return(lResult ^ 0x40000000 ^ lX8 ^ lY8);} else {return(lResult ^ lX8 ^ lY8);}}var F = function(x, y, z) {return(x & y) | ((~x) & z);}var G = function(x, y, z) {return(x & z) | (y & (~z));}var H = function(x, y, z) {return(x ^ y ^ z);}var I = function(x, y, z) {return(y ^ (x | (~z)));}var FF = function(a, b, c, d, x, s, ac) {a = addUnsigned(a, addUnsigned(addUnsigned(F(b, c, d), x), ac));return addUnsigned(rotateLeft(a, s), b);};var GG = function(a, b, c, d, x, s, ac) {a = addUnsigned(a, addUnsigned(addUnsigned(G(b, c, d), x), ac));return addUnsigned(rotateLeft(a, s), b);};var HH = function(a, b, c, d, x, s, ac) {a = addUnsigned(a, addUnsigned(addUnsigned(H(b, c, d), x), ac));return addUnsigned(rotateLeft(a, s), b);};var II = function(a, b, c, d, x, s, ac) {a = addUnsigned(a, addUnsigned(addUnsigned(I(b, c, d), x), ac));return addUnsigned(rotateLeft(a, s), b);};var convertToWordArray = function(string) {var lWordCount;var lMessageLength = string.length;var lNumberOfWordsTempOne = lMessageLength + 8;var lNumberOfWordsTempTwo = (lNumberOfWordsTempOne - (lNumberOfWordsTempOne % 64)) / 64;var lNumberOfWords = (lNumberOfWordsTempTwo + 1) * 16;var lWordArray = Array(lNumberOfWords - 1);var lBytePosition = 0;var lByteCount = 0;while(lByteCount < lMessageLength) {lWordCount = (lByteCount - (lByteCount % 4)) / 4;lBytePosition = (lByteCount % 4) * 8;lWordArray[lWordCount] = (lWordArray[lWordCount] | (string.charCodeAt(lByteCount) << lBytePosition));lByteCount++;}lWordCount = (lByteCount - (lByteCount % 4)) / 4;lBytePosition = (lByteCount % 4) * 8;lWordArray[lWordCount] = lWordArray[lWordCount] | (0x80 << lBytePosition);lWordArray[lNumberOfWords - 2] = lMessageLength << 3;lWordArray[lNumberOfWords - 1] = lMessageLength >>> 29;return lWordArray;};var wordToHex = function(lValue) {var WordToHexValue = "",WordToHexValueTemp = "",lByte, lCount;for(lCount = 0;
