kandi X-RAY | goquery Summary

goquery is a Go library typically used in Utilities, Parser applications. goquery has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

goquery brings a syntax and a set of features similar to jQuery to the Go language. It is based on Go's net/html package and the CSS Selector library cascadia. Since the net/html parser returns nodes, and not a full-featured DOM tree, jQuery's stateful manipulation functions (like height(), css(), detach()) have been left off. Also, because the net/html parser requires UTF-8 encoding, so does goquery: it is the caller's responsibility to ensure that the source document provides UTF-8 encoded HTML. See the wiki for various options to do this. Syntax-wise, it is as close as possible to jQuery, with the same function names when possible, and that warm and fuzzy chainable interface. jQuery being the ultra-popular library that it is, I felt that writing a similar HTML-manipulating library was better to follow its API than to start anew (in the same spirit as Go's fmt package), even though some of its methods are less than intuitive (looking at you, index()...).

Strange len function (or string) behavior

Asked 2021-Oct-03 at 21:17

I'm trying to parse the timetable content using goquery to work with it later. But I have a problem.

I have two functions. The first one takes an html document and searches for a token (csrfmiddlewaretoken) and the second one sends a request using this token and extracts information. Finishing extracting all necessary information from the page, I search for the token to use it in future request and store it.

But for some reason found token turns into an empty string when it reaches if len(foundCsrfToken) == 0 {. If I print length of the token just before the statement it prints this:

I've just realized what is wrong. io.Reader is treated as a stream. So when I make read from it once, it becomes empty. As you can see, after gathering all necessary information and reading the response, it is passed into the first function. But it's already empty. When I call findCsrfMiddlewareToken function for the first time, it works as usual and prints token length (64). But when I get to second call with empty response, it prints 0.

Possible solution: How to read multiple times from same io.Reader

QUESTION

Web crawler stops at first page

Asked 2021-Jul-15 at 05:39

I'm working on a webcrawler which should be working like this:

go to a website, crawl all links from the site
download all images (starting from the startpage)
if there are no images left on the current page, go to the next link found in step 1 and do step 2 and 3 until there are no links/images left.

It seems like the code below is somehow working, like when I try to crawl some sites, I get some images to download.

(even I dont understand the images I get, cause I cant find them on the website, it seems like the crawler does not start with the startpage of the website).

After a few images (~25-500), the crawler is done and stops, no errors, it just stops. I tried this with multiple websites and after a few images it just stops. I think the crawler somehow ignores step 3.

Yes you are right. Your code will not download images from the start page because the only thing it is fetching from start page are all anchor tag elements and then calling processElement() for each anchor element found on the start page -

QUESTION

Waiting for all goroutines to finish and combining the results

Asked 2021-Feb-05 at 16:38

I have some hard times understanding goroutines, channels and all sync thing. I believe I understand the concepts, but I'm missing a couple of lines to connect all the information I have. Also, the majority of the examples feel too simple, so I can't get the proper grasp of what's actually happening.

I'm writing a simple analytics tool for websites. One of the features is to check whether all links on this website are reachable. Obviously, there are many links on each website, so it seems like a great goroutines candidate. The thing is that after scheduling all goroutines I'd need to get back all results in order to present them to the user all at once.

What I have so far is:

You could use a semaphore to constrain the concurrency. This still spawns "1000 goroutines", but ensures that only 5 http requests are in flight at a given time. You can change the value of maxParallel to increase or decrease the number of parallel requests.

The gist of this error is that the version of binary used to generate the code isn't compatible with the current version of code. A quick and easy solution would be to try updating the protoc-gen-go compiler and the gRPC library to the latest version.

go get -u github.com/golang/protobuf/protoc-gen-go

How to avoid indirect dependencies in go.mod file

Asked 2020-Apr-09 at 08:24

I am running go build to get my go.mod file updated with library I am using "github.com/gocolly/colly v1.2.0" But I see all other dependencies saying "// indirect" at end. How to avoid getting this? Here is my go.mod file

...

ANSWER

Answered 2020-Apr-09 at 08:24

Unfortunately, you can't avoid them. Indirect dependency, is basically dependency that wasn't listed in go.mod of your direct dependency, but is still required by it.

In your case it happens, because you use github.com/gocolly/colly v1.2.0 as dependency and v1.2.0 of this package isn't a module, because it doesn't contain go.mod, so all it's dependencies are indirect and listed in your go.mod with indirect tag.

Note, that colly has go.mod in >=v2.0.0, so if you require that version, these dependencies won't be listed as indirect in your go.mod.
