javascript - Antara muka pengambilan Qiniu menangkap sumber pihak ketiga (gambar rangkaian), dan mesej ralat yang dikembalikan oleh permintaan ajax JS sentiasa "Tidak dibenarkan"

Question

Keizinan permintaan pengambilan gagal Saya tidak tahu sama ada ia ralat penyambungan laluan atau ralat dalam permintaan ajax yang ditulis.

//Urus bukti kelayakan
fungsi 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) {

// 通过fetch进行远程图片抓取
var accessKey = "AK";
var secretKey = "SK";
//网络图片picurl上传到七牛
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', //服务器返回json格式数据
    type: 'post', //HTTP请求类型
    timeout: 10000, //超时时间设置为10秒；
    headers: {
        'Authorization': "QBox " + genManageToken(accessKey, secretKey, path, ""),
        'Content-Type': 'application/json',
    },
    success: function(data) {
        //服务器返回响应，根据响应结果，分析是否登录成功；
        data = JSON.stringify(data);
        data = eval("(" + data + ")");
        //输出响应成功key值
        console.log(data['key']);
    },
    error: function(xhr, type, errorThrown) {
        //异常处理；
        console.log(errorThrown);
    }
});

}

fungsi safe64(base64) {

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

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

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

}
