上传一直报403 (Forbidden)

Question

用了jsSDK和nodeSDK，nodeSDK返回jsSDK需要的token，上传一直报403 (Forbidden)错误，

存储空间用的是华南区域的，地址也对应了，

附上代码

• 前台：

let uploader = Qiniu.uploader({
    runtimes: 'html5,flash,html4',
    browse_button: 'upload',
    uptoken_url: './videos/upToken',
    get_new_uptoken: true,
    domain: 'http://on5gjg7q0.bkt.clouddn.com',
    max_file_size: '100mb',
    max_retries: 1,
    chunk_size: '10mb',
    auto_start: true,
    unique_names: true,
    init: {
        'UploadProgress': function (up, file) {
            // 每个文件上传时，处理相关的事情
            let chunk_size = plupload.parseSize(this.getOption('chunk_size'));
            console.log(chunk_size);
            app.speed = Math.round(file.speed / 1024) + 'KB/S';
            app.percentage = file.percent;
        },
        'FileUploaded': function (up, file, info) {
            let domain = up.getOption('domain');
            let res = $.parseJSON(info);
            let sourceLink = domain + "/" + res.key;
            console.log(sourceLink);

        },
        'Error': function (up, err, errTip) {
            //上传出错时，处理相关的事情
            console.log()
        },
        'UploadComplete': function () {
            //队列文件处理完毕后，处理相关的事情
        }
    }
});

• 后台

    upToken: function (req, res, next) {
        let putPolicy = new qiniu.rs.PutPolicy(bucket + ":" + key);
        //putPolicy.callbackUrl = 'http://your.domain.com/callback';
        //putPolicy.callbackBody = 'filename=$(fname)&filesize=$(fsize)';
        res.json({"uptoken": putPolicy.token()});
        console.log(putPolicy.token());
        return putPolicy.token();
    },

浏览器控制台报错：

如何解决？

Answer 1

自己解决了，主要有两点，第一：前段js-sdk的‘domain’字段填的是存储空间的域名，而后端node-sdk返回token的‘bucket’字段填的是存储空间名。第二：报错的内容为‘key doesn't match with scope’就是前后端的key值不匹配，七牛官方node demo中默认包含key，即let putPolicy = new qiniu.rs.PutPolicy(bucket + ":" + key);这句代码，但是js-sdk中却没有定义key，两者不匹配，所以报错，解决办法把后端改成let putPolicy = new qiniu.rs.PutPolicy(bucket);即可
