問題描述

fetch請求授權(quán)失敗了不知道是path拼接錯誤還是寫的ajax請求有錯誤。

//管理憑證function genManageToken(accessKey, secretKey, pathAndQuery, body) {

var str = pathAndQuery + 'n' + body;var hash = CryptoJS.HmacSHA1(str, secretKey);var encodedSign = CryptoJS.enc.Base64.stringify(CryptoJS.enc.Utf8.parse(hash));return accessKey + ':' + encodedSign;

}

var fetchImg = function(picUrl) {

// 通過fetch進行遠程圖片抓取var accessKey = 'AK';var secretKey = 'SK';//網(wǎng)絡(luò)圖片picurl上傳到七牛var srcUrl = CryptoJS.enc.Base64.stringify(CryptoJS.enc.Utf8.parse(picUrl));var bucket = CryptoJS.enc.Base64.stringify(CryptoJS.enc.Utf8.parse('bucket'));var path = '/fetch/' + srcUrl + '/to/' + bucket;var fetchUrl = 'http://iovip.qbox.me/' + path;mui.ajax(fetchUrl, { dataType: ’json’, //服務(wù)器返回json格式數(shù)據(jù) type: ’post’, //HTTP請求類型 timeout: 10000, //超時時間設(shè)置為10秒； headers: {’Authorization’: 'QBox ' + genManageToken(accessKey, secretKey, path, ''),’Content-Type’: ’application/json’, }, success: function(data) {//服務(wù)器返回響應(yīng)，根據(jù)響應(yīng)結(jié)果，分析是否登錄成功；data = JSON.stringify(data);data = eval('(' + data + ')');//輸出響應(yīng)成功key值console.log(data[’key’]); }, error: function(xhr, type, errorThrown) {//異常處理；console.log(errorThrown); }});

}

問題解答

function safe64(base64) {

base64 = base64.replace(/+/g, '-');base64 = base64.replace(///g, '_');return base64;

}function genManageToken(accessKey, secretKey, pathAndQuery, body) {

var str = pathAndQuery + 'n' + body;var hash = CryptoJS.HmacSHA1(str, secretKey); var encodedSign = safe64(hash.toString(CryptoJS.enc.Base64));

}編碼問題已解決。
