⚠ Warning
The implementation relies on Google's search page DOM being constant. From time to time, Google changes their DOM and thus breaks the implementation.
In the event it changes, this package will be updated as soon as possible.
Also note, that if you call this function too quickly, Google detects that it is being scraped and produces a recaptcha which interferes with the scraping. Don't call it in quick succession. It may take some time before Google unblocks you.
Always use the built-in rate-limiter set to reasonable settings.
HTTP STATUS CODE: 429 — Too Many Requests

Constants ¶

Variables ¶
var ErrBlocked = errors.New("google block")
ErrBlocked indicates that Google has detected that you were scraping and temporarily blocked you. The duration of the block is unspecified.
See: https://github.com/rocketlaunchr/google-search#warning-warning
var GoogleDomains = map[string]string{}/* 198 elements not displayed */
GoogleDomains represents localized Google homepages. The 2 letter country code is based on ISO 3166-1 alpha-2.
See: https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2
var RateLimit = rate.NewLimiter(rate.Inf, 0)
RateLimit sets a global limit to how many requests to Google Search can be made in a given time interval. The default is unlimited (but obviously Google Search will block you temporarily if you do too many calls too quickly).
Functions ¶
This section is empty.
Types ¶
type Result ¶
type Result struct {
// Rank is the order number of the search result.
Rank int `json:"rank"`
// URL of result.
URL string `json:"url"`
// Title of result.
Title string `json:"title"`
// Description of the result.
Description string `json:"description"`
}
Result represents a single result from Google Search.
func Search ¶
Search returns a list of search results from Google.
Example ¶
opt := SearchOptions{
CountryCode: "au",
}
//lint:ignore SA1012 ignore this bare essentials by passing nil for context and removing context package (despite not being idiomatic go).
serp, err := Search(nil, "First Aid Course Australia Wide First Aid", opt)
if err != nil {
fmt.Print(err.Error())
}
for _, result := range serp {
if strings.Contains(result.URL, "australiawidefirstaid.com.au") {
fmt.Println("Australia Wide First Aid (https://www.australiawidefirstaid.com.au/) found in the serp")
break
}
}
Output: Australia Wide First Aid (https://www.australiawidefirstaid.com.au/) found in the serp
type SearchOptions ¶
type SearchOptions struct {
// CountryCode sets the ISO 3166-1 alpha-2 code of the localized Google Search homepage to use.
// The default is "us", which will return results from https://www.google.com.
CountryCode string
// LanguageCode sets the language code.
// Default: en
LanguageCode string
// Limit sets how many results to fetch (at maximum).
Limit int
// Start sets from what rank the new result set should return.
Start int
// UserAgent sets the UserAgent of the http request.
// Default: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/61.0.3163.100 Safari/537.36"
UserAgent string
// OverLimit searches for more results than that specified by Limit.
// It then reduces the returned results to match Limit.
OverLimit bool
// ProxyAddr sets a proxy address to avoid IP blocking.
ProxyAddr string
// FollowNextPage, when set, scrapes subsequent result pages.
FollowNextPage bool
}
SearchOptions modifies how the Search function behaves.
