IPinfo API 的官方 Java 库（IP 地理位置和其他类型的 IP 数据）.zip

# [<img src="https://ipinfo.io/static/ipinfo-small.svg" alt="IPinfo" width="24"/>](https://ipinfo.io/) IPinfo Java Client Library [](LICENSE) This is the official Java client library for the [IPinfo.io](https://ipinfo.io) IP address API, allowing you to look up your own IP address, or get any of the following details for an IP: - [IP geolocation data](https://ipinfo.io/ip-geolocation-api) (city, region, country, postal code, latitude, and longitude) - [ASN information](https://ipinfo.io/asn-api) (ISP or network operator, associated domain name, and type, such as business, hosting, or company) - [Company data](https://ipinfo.io/ip-company-api) (the name and domain of the business that uses the IP address) - [Carrier details](https://ipinfo.io/ip-carrier-api) (the name of the mobile carrier and MNC and MCC for that carrier if the IP is used exclusively for mobile traffic) Check all the data we have for your IP address [here](https://ipinfo.io/what-is-my-ip). ### Getting Started You'll need an IPinfo API access token, which you can get by signing up for a free account at [https://ipinfo.io/signup](https://ipinfo.io/signup). The free plan is limited to 50,000 requests per month, and doesn't include some of the data fields such as IP type and company data. To enable all the data fields and additional request volumes see [https://ipinfo.io/pricing](https://ipinfo.io/pricing) [Click here to view the Java SDK's API documentation](https://ipinfo.github.io/java/). #### Installation ##### Maven Add these values to your pom.xml file: Dependency: ```xml <dependencies> <dependency> <groupId>io.ipinfo</groupId> <artifactId>ipinfo-api</artifactId> <version>3.0.0</version> <scope>compile</scope> </dependency> </dependencies> ``` #### Quick Start ##### IP Information ````java import io.ipinfo.api.IPinfo; import io.ipinfo.api.errors.RateLimitedException; import io.ipinfo.api.model.IPResponse; public class Main { public static void main(String... args) { IPinfo ipInfo = new IPinfo.Builder() .setToken("YOUR TOKEN") .build(); try { IPResponse response = ipInfo.lookupIP("8.8.8.8"); // Print out the hostname System.out.println(response.getHostname()); } catch (RateLimitedException ex) { // Handle rate limits here. } } } ```` ##### ASN Information ````java import io.ipinfo.api.IPinfo; import io.ipinfo.api.errors.RateLimitedException; import io.ipinfo.api.model.IPResponse; public class Main { public static void main(String... args) { IPinfo ipInfo = new IPinfo.Builder() .setToken("YOUR TOKEN") .build(); try { ASNResponse response = ipInfo.lookupASN("AS7922"); // Print out country name System.out.println(response.getCountry()); } catch (RateLimitedException ex) { // Handle rate limits here. } } } ```` #### Errors - `ErrorResponseException`: A runtime exception accessible through the `ExecutionException` of a future. This exception signals that something went wrong when mapping the API response to the wrapper. You probably can't recover from this exception. - `RateLimitedException` An exception signaling that you've been rate limited. #### Caching This library provides a very simple caching system accessible in `SimpleCache`. Simple cache is an in-memory caching system that resets every time you restart your code. If you prefer a different caching methodology, you may use the `Cache` interface and implement your own caching system around your own infrastructure. The default cache length is 1 day, this can be changed by calling the SimpleCache constructor yourself. ```java import io.ipinfo.api.IPinfo; import io.ipinfo.api.errors.RateLimitedException; import io.ipinfo.api.model.IPResponse; public class Main { public static void main(String... args) { // 5 Day Cache IPinfo ipInfo = new IPinfo.Builder() .setToken("YOUR TOKEN") .setCache(new SimpleCache(Duration.ofDays(5))) .build(); try { IPResponse response = ipInfo.lookupIP("8.8.8.8"); // Print out the hostname System.out.println(response.getHostname()); } catch (RateLimitedException ex) { // Handle rate limits here. } } } ``` #### Country Name Lookup This library provides a system to lookup country names through ISO2 country codes. ```java import io.ipinfo.api.IPinfo; import io.ipinfo.api.errors.RateLimitedException; import io.ipinfo.api.model.IPResponse; public class Main { public static void main(String... args) { IPinfo ipInfo = new IPinfo.Builder() .setToken("YOUR TOKEN") .build(); try { IPResponse response = ipInfo.lookupIP("8.8.8.8"); // Print out the country code System.out.println(response.getCountryCode()); // Print out the country name System.out.println(response.getCountryName()); } catch (RateLimitedException ex) { // Handle rate limits here. } } } ``` #### EU Country Lookup This library provides a system to lookup if a country is a member of the European Union (EU) through ISO2 country codes. ```java import io.ipinfo.api.IPinfo; import io.ipinfo.api.errors.RateLimitedException; import io.ipinfo.api.model.IPResponse; public class Main { public static void main(String... args) { IPinfo ipInfo = new IPinfo.Builder() .setToken("YOUR TOKEN") .build(); try { IPResponse response = ipInfo.lookupIP("8.8.8.8"); // Print out whether the country is a member of the EU System.out.println(response.isEU()); } catch (RateLimitedException ex) { // Handle rate limits here. } } } ``` #### Internationalization This library provides a system to lookup if a country is a member of the European Union (EU), emoji and unicode of the country's flag, code and symbol of the country's currency, and public link to the country's flag image as an SVG and continent code and name through ISO2 country codes. ```java import io.ipinfo.api.IPinfo; import io.ipinfo.api.errors.RateLimitedException; import io.ipinfo.api.model.IPResponse; public class Main { public static void main(String... args) { IPinfo ipInfo = new IPinfo.Builder() .setToken("YOUR TOKEN") .build(); try { IPResponse response = ipInfo.lookupIP("8.8.8.8"); // Print out whether the country is a member of the EU System.out.println(response.isEU()); // CountryFlag{emoji='🇺🇸',unicode='U+1F1FA U+1F1F8'} System.out.println(response.getCountryFlag()); // https://cdn.ipinfo.io/static/images/countries-flags/US.svg System.out.println(response.getCountryFlagURL()); // CountryCurrency{code='USD',symbol='$'} System.out.println(response.getCountryCurrency()); // Continent{code='NA',name='North America'} System.out.println(response.getContinent()); } catch (RateLimitedException ex) { // Handle rate limits here. } } } ``` #### Location Information This library provides an easy way to get the latitude and longitude of an IP Address: ```java import io.ipinfo.api.IPinfo; import io.ipinfo.api.errors.RateLimitedException; import io.ipinfo.api.model.IPResponse; public class Main { public static void main(String... args) { IPinfo ipInfo = new IPinfo.Builder() .setToken("YOUR TOKEN") .build(); try { IPResponse response = ipInfo.lo
