我正在使用供应商创建的电子学习课程(我们不再处理这些课程),以及何时通过我公司的安全软件(HP Fortify Scan)上传文件我&#39 ;我得到多个错误。我已经纠正了所有错误。错误发生在dojo.js文件中,它与未经验证的url
变量有关。我确定这是一个简单的解决方法,但有人可以解释是什么原因导致无效吗?我该如何验证此url
变量?
以下是带有代码的错误消息的屏幕截图(我将行号放在注释中):
代码:
function xhr(url, options, returnDeferred){
var response = util.parseArgs(
url,
util.deepCreate(defaultOptions, options),
has('native-formdata') && options && options.data && options.data instanceof FormData
);
// THIS IS LINE 11540
url = response.url;
options = response.options;
var remover,
last = function(){
remover && remover();
};
//Make the Deferred object for this xhr request.
var dfd = util.deferred(
response,
cancel,
isValid,
isReady,
handleResponse,
last
);
var _xhr = response.xhr = xhr._create();
if(!_xhr){
// If XHR factory somehow returns nothings,
// cancel the deferred.
dfd.cancel(new RequestError('XHR was not created'));
return returnDeferred ? dfd : dfd.promise;
}
response.getHeader = function(headerName){
return this.xhr.getResponseHeader(headerName);
};
if(addListeners){
remover = addListeners(_xhr, dfd, response);
}
var data = options.data,
async = !options.sync,
method = options.method;
try{
// IE6 won't let you call apply() on the native function.
// THIS IS LINE 11580
_xhr.open(method, url, async, options.user || undefined, options.password || undefined);
if(options.withCredentials){
_xhr.withCredentials = options.withCredentials;
}
var headers = options.headers,
contentType;
if(headers){
for(var hdr in headers){
if(hdr.toLowerCase() === 'content-type'){
contentType = headers[hdr];
}else if(headers[hdr]){
//Only add header if it has a value. This allows for instance, skipping
//insertion of X-Requested-With by specifying empty value.
_xhr.setRequestHeader(hdr, headers[hdr]);
}
}
}
if(contentType && contentType !== false){
_xhr.setRequestHeader('Content-Type', contentType);
}
if(!headers || !('X-Requested-With' in headers)){
_xhr.setRequestHeader('X-Requested-With', 'XMLHttpRequest');
}
if(util.notify){
util.notify.emit('send', response, dfd.promise.cancel);
}
_xhr.send(data);
}catch(e){
dfd.reject(e);
}
watch(dfd);
_xhr = null;
return returnDeferred ? dfd : dfd.promise;
}

我说这不一定是错误,只是HP Fortify Scan指出dojo / request / xhr.js中的一段代码,如果您的服务器代码是没有为这样的攻击做好准备...您可以在您的应用程序(可能在您的商店中)中调用xhr()的更高级代码验证URL,不确定它是否满足HP Fortify。
