Software Introduction

QuaggaJS is a barcode scanning library completely written in JavaScript, which supports real-time barcode scanning of various types, such as EAN and CODE128 . This tool is used at the same time getUserMedia To access the user's camera directly. The code relies heavily on the image processing of smart phones.

You can try some here example Or read the article（ How barcode-localization works in QuaggaJS ）To understand the content of the update relationship.

Sample code:

 Quagga.decodeSingle({   readers: ['code_128_reader'],   locate: true, // try to locate the barcode in the image   src: '/test/fixtures/code_128/image-001.jpg' // or 'data:image/jpg; base64,' + data }, function(result){   console.log(result); });

Not everyone will go to see the document in full detail. As a general basic framework, the method naming should consider not only readability but also understandability. At least, it should also establish a cognition for developers. LambdaQueryWrapper is recommended. The official only briefly said that QueryWrapper may lead to SQL injection risks, There are no detailed examples (many people don't understand what SQL injection is). Now I met a jerk and submitted it to CVE to see who is the most powerful

Why is this so-called "vulnerability" not a vulnerability? Spring, MyBatis and other frameworks can accept all kinds of CVE criticism, while MyBatisPlus has to dump the pot and accuse programmers of being too low-level# There is a difference. The premise is that you write XML, MyBatisPlus encapsulates Wrapper and claims to simplify code. Since it encapsulates and hides $#, it is not appropriate to do some necessary security checks? Instead of doubting the authority of CVE, you should know that SQL ->MyBatis ->MyBatisPlus ->various back-end scaffolds have multiple layers, each layer is simplifying, and each layer is throwing away the upper layer of the boiler. Who dares to use them. The programmers who use MyBatisPlus can't be expected to be at a high level. Every programmer wants to save effort. The front-end parameters can be directly obtained by HttpServletRequest from the back-end. Wrapper splicing can be found everywhere. If something goes wrong, is it the front-end or the framework? According to Qingmiao, can the injection vulnerability of the previous log4j and the deletion vulnerability of the Druid be used to eliminate low-level programmers?

It is compatible with Oracle, but does not know "just" or "just". Those who can be compatible with Oracle and do well are real men and real warriors. You should know that compatibility means that even bugs must be compatible, and you have no other code that can not be copied. It's all based on real skills and understanding of oracle.

There is no tipping point. There are also many official documents stating that SQL fragments involving direct string splicing need to be controlled by the user, and specific solutions are also provided. If you say that the value part is injected, then we are also 100% free of any dispute. This obvious SQL fragment is unrealistic for ORM to explain without your control, Since SQL allows splicing fragments, there must be some scenarios that cannot be forced into non SQL strings. It is also very simple. Have you ever thought about why not force them???

It seems that the current version of the Foreign Function&Memory API is not as fast as that of jni, or even worse. In addition, before vallhala comes out, all interactions between java and c have to get an additional memory. Even if it comes out, it may not be possible to directly throw a copy of binary data into memory as a structure. When the two apis are completely stable, the day lily is cold

If only the design and architecture are similar, what's the point? Good things must be learned, and you can't prove that the design is not the same. As for the source code, you also said that neither Oracle nor Damon is open source, and you can't prove it. There are many people who question Dream, but so far, no one has come up with strong evidence. You should at least provide evidence to copy

@Qingmiao Hutool has also been mentioned some loopholes that I think are relatively "low-level", or I think are not loopholes. At first, I was also very angry, but after thinking it through, I found that CVE's idea was that once you did not actively remind users that there was a pit, the user fell into the pit is your fault, that is, your vulnerability. For example, as a traffic policeman, you should remind everyone who crosses the road to pay attention to safety, and ask him to answer whether he knows. Once you don't remind someone and are hit by a car, you can't get away from it. Similarly, when using frameworks and tools, you should provide at least one parameter to remind users that there may be SQL injection vulnerabilities. Note that it is not in the comments, but in the method parameters, which is the user's responsibility. Therefore, it is not comprehensive to provide solutions in comments or documents.

Don't expect programmers to have a deep understanding of the document. I still think that since the tool hides the details of $#, some necessary security checks are necessary. Many people do not use MybatisPlus directly, but use various so-called rapid development platforms. The MyBatisPlus rapid development platform Snowy, Guns, etc., has an impression that many versions have the problem of using Wrapper directly to splice the Request parameter. I remember that JeecgBoot was opened a lot of CVEs last year or the year before last because of the Wrapper splicing problem. Do you know the author of ibeetl? Many CVE blaming holes have been opened before. The problem is similar. The lack of basic knowledge "script editing permission" is actively handed over to the front end. What a low-level error or even low-energy behavior. However, I accepted it with an open mind and added a white list check.
