脚本宝典收集整理的这篇文章主要介绍了uniapp实现阿里oss直传(app端),脚本宝典觉得挺不错的,现在分享给大家,也给大家做个参考。
保姆级教程 大神请绕道 有哪里不对的地方还望指点
注意:开通的阿里oss需要允许跨域访问
首先需要导入阿里oss的工具包
导入方式:
1.打开项目终端
输入
npm inIT -y
然后输入
npm install ali-oss
稍等片刻安装好后控制台会出现
至此你已经安装好了阿里oss的工具包
在项目根目录下创建common文件夹(如果有该文件夹忽略此步)
在创建的common文件下创建bundle.js文件,把下面的代码复制进去
//bundle.js VAR base64map = "abcDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/"; // Global Crypto object var Crypto = {}; // Crypto utilities var util = Crypto.util = { // Bit-wise rotate left rotl: function (n, b) { return (n << b) | (n >>> (32 - b)); }, // Bit-wise rotate right rotr: function (n, b) { return (n << (32 - b)) | (n >>> b); }, // Swap Big-endian to liTTLe-endian and vice versa endian: function (n) { // If number given, swap endian if (n.constructor == Number) { return util.rotl(n, 8) & 0x00FF00FF | util.rotl(n, 24) & 0xFF00FF00; } // Else, assume array and swap all items for (var i = 0; i < n.length; i++) n[i] = util.endian(n[i]); return n; }, // Generate an array of any length of random bytes randomBytes: function (n) { for (var bytes = []; n > 0; n--) bytes.push(Math.floor(Math.random() * 256)); return bytes; }, // Convert a string to a byte array stringToBytes: function (str) { var bytes = []; for (var i = 0; i < str.length; i++) bytes.push(str.charCodeAt(i)); return bytes; }, // Convert a byte array to a string bytestoString: function (bytes) { var str = []; for (var i = 0; i < bytes.length; i++) str.push(String.FromCharCode(bytes[i])); return str.join(""); }, // Convert a string to big-endian 32-bit words stringToWords: function (str) { var words = []; for (var c = 0, b = 0; c < str.length; c++, b += 8) words[b >>> 5] |= str.charCodeAt(c) << (24 - b % 32); return words; }, // Convert a byte array to big-endian 32-bits words bytesToWords: function (bytes) { var words = []; for (var i = 0, b = 0; i < bytes.length; i++, b += 8) words[b >>> 5] |= bytes[i] << (24 - b % 32); return words; }, // Convert big-endian 32-bit words to a byte array wordsToBytes: function (words) { var bytes = []; for (var b = 0; b < words.length * 32; b += 8) bytes.push((words[b >>> 5] >>> (24 - b % 32)) & 0xFF); return bytes; }, // Convert a byte array to a hex string bytesToHex: function (bytes) { var hex = []; for (var i = 0; i < bytes.length; i++) { hex.push((bytes[i] >>> 4).toString(16)); hex.push((bytes[i] & 0xF).toString(16)); } return hex.join(""); }, // Convert a hex string to a byte array hexToBytes: function (hex) { var bytes = []; for (var c = 0; c < hex.length; c += 2) bytes.push(parseint(hex.substr(c, 2), 16)); return bytes; }, // Convert a byte array to a base-64 string bytesToBase64: function (bytes) { // Use browser-native function if it exists // if (tyPEof BToa == "function") return btoa(util.bytesToString(bytes)); var base64 = [], overflow; for (var i = 0; i < bytes.length; i++) { switch (i % 3) { case 0: base64.push(base64map.charAt(bytes[i] >>> 2)); overflow = (bytes[i] & 0x3) << 4; break; case 1: base64.push(base64map.charAt(overflow | (bytes[i] >>> 4))); overflow = (bytes[i] & 0xF) << 2; break; case 2: base64.push(base64map.charAt(overflow | (bytes[i] >>> 6))); base64.push(base64map.charAt(bytes[i] & 0x3F)); overflow = -1; } } // Encode overflow bits, if there are any if (overflow != undefined && overflow != -1) base64.push(base64map.charAt(overflow)); // Add padding while (base64.length % 4 != 0) base64.push("="); return base64.join(""); }, // Convert a base-64 string to a byte array base64ToBytes: function (base64) { // Use browser-native function if it exists if (typeof atob == "function") return util.stringToBytes(atob(base64)); // Remove non-base-64 characters base64 = base64.replace(/[^A-Z0-9+/]/ig, ""); var bytes = []; for (var i = 0; i < base64.length; i++) { switch (i % 4) { case 1: bytes.push((base64map.indexOf(base64.charAt(i - 1)) << 2) | (base64map.indexOf(base64.charAt(i)) >>> 4)); break; case 2: bytes.push(((base64map.indexOf(base64.charAt(i - 1)) & 0xF) << 4) | (base64map.indexOf(base64.charAt(i)) >>> 2)); break; case 3: bytes.push(((base64map.indexOf(base64.charAt(i - 1)) & 0x3) << 6) | (base64map.indexOf(base64.charAt(i)))); break; } } return bytes; } }; // Crypto mode namespace Crypto.mode = {}; //hmac var util = Crypto.util; Crypto.HMAC = function (hasher, message, key, options) { // Allow arbitrary length keys key = key.length > hasher._blocksize * 4 ?

接下来调用的地方:
