Hướng dẫn javascript object-hash
Generate hashes from objects and values in node and the browser. Uses node.js crypto module for hashing. Supports SHA1 and many others (depending on the platform) as well as custom streams (e.g. CRC32). Nội dung chính
var hash = require('object-hash'); hash({foo: 'bar'}) // => '67b69634f9880a282c14a0f0cb7ba20cf5d677e9' hash([1, 2, 2.718, 3.14159]) // => '136b9b88375971dff9f1af09d7356e3e04281951' Versioning DisclaimerStarting with version For more information, see this discussion. hash(value, options)Generate a hash from any object or type. Defaults to sha1 with hex encoding.
hash.sha1(value)Hash using the sha1 algorithm. Note that SHA-1 is not considered secure, and a stronger algorithm should be used if a cryptographical hash is desired. Sugar method,
equivalent to hash.keys(value)Hash object keys using the sha1 algorithm, values ignored. Sugar method, equivalent to hash.MD5(value)Hash using the md5 algorithm. Note that the MD5 algorithm is not considered secure, and a stronger algorithm should be used if a cryptographical hash is desired. Sugar method, equivalent to hash.keysMD5(value)Hash object keys using the md5 algorithm, values ignored. Note that the MD5 algorithm is not considered secure, and a stronger algorithm should be used if a cryptographical hash is desired. Sugar method, equivalent to hash.writeToStream(value, [options,] stream)Write the information that would otherwise have been hashed to a stream, e.g.: hash.writeToStream({foo: 'bar', a: 42}, {respectType: false}, process.stdout) // => e.g. 'object:a:number:42foo:string:bar' Installationnode: browser: /dist/object_hash.js <script src="object_hash.js" type="text/javascript">script> <script> var hash = objectHash.sha1({foo:'bar'}); console.log(hash); // e003c89cdf35cdf46d8239b4692436364b7259f9 script> Example usagevar hash = require('object-hash'); var peter = { name: 'Peter', stapler: false, friends: ['Joanna', 'Michael', 'Samir'] }; var michael = { name: 'Michael', stapler: false, friends: ['Peter', 'Samir'] }; var bob = { name: 'Bob', stapler: true, friends: [] }; /*** * sha1 hex encoding (default) */ hash(peter); // 14fa461bf4b98155e82adc86532938553b4d33a9 hash(michael); // 4b2b30e27699979ce46714253bc2213010db039c hash(bob); // 38d96106bc8ef3d8bd369b99bb6972702c9826d5 /*** * hash object keys, values ignored */ hash(peter, { excludeValues: true }); // 48f370a772c7496f6c9d2e6d92e920c87dd00a5c hash(michael, { excludeValues: true }); // 48f370a772c7496f6c9d2e6d92e920c87dd00a5c hash.keys(bob); // 48f370a772c7496f6c9d2e6d92e920c87dd00a5c /*** * hash object, ignore specific key(s) */ hash(peter, { excludeKeys: function(key) { if ( key === 'friends') { return true; } return false; } }); // 66b7d7e64871aa9fda1bdc8e88a28df797648d80 /*** * md5 base64 encoding */ hash(peter, { algorithm: 'md5', encoding: 'base64' }); // 6rkWaaDiG3NynWw4svGH7g== hash(michael, { algorithm: 'md5', encoding: 'base64' }); // djXaWpuWVJeOF8Sb6SFFNg== hash(bob, { algorithm: 'md5', encoding: 'base64' }); // lFzkw/IJ8/12jZI0rQeS3w== Legacy Browser SupportIE <= 8 and Opera <= 11 support dropped in version 0.3.0. If you require legacy browser support you must either use an ES5 shim or use version 0.2.5 of this module.
