ajax unauthorized,七牛fetch接口抓取第三方资源(网络图片),Js写ajax请求返回error错误信息总是“Unauthorized”...

fetch请求授权失败了不知道是path拼接错误还是写的ajax请求有错误。

//管理凭证

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);

}

});

}
