Java library for scraping and crawling websites using the ProxyCrawl API.
Import the needed libraries in your project
import java.util.*;
import com.proxycrawl.*;
Initialize the API with one of your account tokens, either normal or javascript token. Then make get or post requests accordingly.
You can get a token for free by creating a ProxyCrawl account and 1000 free testing requests. You can use them for tcp calls or javascript calls or both.
API api = new API("YOUR_TOKEN");
Please note that all the api methods does not throw checked exceptions. All exceptions thrown are RuntimeException
.
Pass the url that you want to scrape plus any options from the ones available in the API documentation.
api.get(url, options);
Example:
api.get("https://www.facebook.com/britneyspears");
System.out.println(api.getStatusCode());
System.out.println(api.getOriginalStatus());
System.out.println(api.getProxyCrawlStatus());
System.out.println(api.getBody());
You can pass any options of what the ProxyCrawl API supports in exact param format.
Example:
HashMap<String, Object> options = new HashMap<String, Object>();
options.put("user_agent", "Mozilla/5.0 (Windows NT 6.2; rv:20.0) Gecko/20121202 Firefox/30.0");
options.put("format", "json");
api.get("https://www.reddit.com/r/pics/comments/5bx4bx/thanks_obama/", options);
System.out.println(api.getStatusCode());
System.out.println(api.getBody());
Pass the url that you want to scrape, the data that you want to send which can be either a json or a string, plus any options from the ones available in the API documentation.
api.post(url, data, options);
Example:
HashMap<String, Object> data = new HashMap<String, Object>();
data.put("text", "example search");
api.post("https://producthunt.com/search", data);
System.out.println(api.getStatusCode());
System.out.println(api.getBody());
You can send the data as application/json instead of x-www-form-urlencoded by setting options post_content_type
as json.
HashMap<String, Object> data = new HashMap<String, Object>();
data.put("some_json", "with some value");
HashMap<String, Object> options = new HashMap<String, Object>();
options.put("post_content_type", "json");
api.post("https://httpbin.org/post", data, options);
System.out.println(api.getStatusCode());
System.out.println(api.getBody());
If you need to scrape any website built with Javascript like React, Angular, Vue, etc. You just need to pass your javascript token and use the same calls. Note that only get
is available for javascript and not post
.
API api = new API("YOUR_JAVASCRIPT_TOKEN");
api.get("https://www.nfl.com");
System.out.println(api.getStatusCode());
System.out.println(api.getBody());
Same way you can pass javascript additional options.
HashMap<String, Object> options = new HashMap<String, Object>();
options.put("page_wait", "5000");
api.get("https://www.freelancer.com", options);
System.out.println(api.getStatusCode());
You can always get the original status and proxycrawl status from the response. Read the ProxyCrawl documentation to learn more about those status.
api.get("https://sfbay.craigslist.org/");
System.out.println(api.getOriginalStatus());
System.out.println(api.getProxyCrawlStatus());
Initialize the Scraper API using your normal token and call the get
method.
ScraperAPI scraper_api = new ScraperAPI("YOUR_TOKEN");
Pass the url that you want to scrape plus any options from the ones available in the Scraper API documentation.
scraper_api.get(url, options);
Example:
scraper_api.get("https://www.amazon.com/Halo-SleepSack-Swaddle-Triangle-Neutral/dp/B01LAG1TOS");
System.out.println(scraper_api.getStatusCode());
System.out.println(scraper_api.getBody());
Initialize with your Leads API token and call the get
method.
LeadsAPI leads_api = new LeadsAPI("YOUR_TOKEN");
leads_api.get("stripe.com");
System.out.println(leads_api.getStatusCode());
System.out.println(leads_api.getBody());
If you have questions or need help using the library, please open an issue or contact us.
Initialize with your Screenshots API token and call the get
method.
ScreenshotsAPI screenshots_api = new ScreenshotsAPI("YOUR_TOKEN");
screenshots_api.get("https://www.apple.com");
System.out.println(screenshots_api.getStatusCode());
System.out.println(screenshots_api.getScreenshotPath());
or specifying a file path
ScreenshotsAPI screenshots_api = new ScreenshotsAPI("YOUR_TOKEN");
HashMap<String, Object> options = new HashMap<String, Object>();
options.put("save_to_path", "/home/my-dir/apple.jpg");
screenshots_api.get("https://www.apple.com", options);
System.out.println(screenshots_api.getStatusCode());
System.out.println(screenshots_api.getScreenshotPath());
Note that screenshots_api.get(url, options)
method accepts an options
Also note that screenshots_api.getBody()
returns a Base64 string representation of the binary image file.
If you want to convert the body to bytes then you have to do the following:
byte[] data = Base64.getDecoder().decode(screenshots_api.getBody());
