OKHttpUtil

Giriş

Açıklaması şöyle

In the Java world, Apache’s HttpClient has always been the dominant Http client before, but because the package is relatively large and the API is difficult to use, it is not used in many scenarios. The emerging OkHttp and Jodd-http are easy to use, but when faced with some scenarios, there are still some learning costs.

Many times, we want to pursue a lightweight Http client and pursue simplicity and ease of use. OKHttp is a set of dependent libraries for processing HTTP network requests. It was designed and developed by Square and is open source. It can currently be used in Java and Kotlin.

For Android Apps, OkHttp now occupies almost all network request operations, and it is also a necessary choice for server-side requests to external interfaces.

HttpUtil Sınıfı

Açıklaması şöyle

For OKHttp, OkHttpUtil has made a layer of encapsulation, making Http requests extremely simple.

Açıklaması şöyle

- Automatically judge whether to request HTTP or HTTPS according to the URL, no need to write redundant code separately.

- By default, cookies are automatically recorded. For example, simulated login can be implemented, that is, subsequent requests after the first visit to the login URL are the login status.

- Automatically identify 304 jumps and make a second request

- Support proxy configuration

- Support referer configuration

- Support User-Agent configuration

- Automatically identify and decompress Gzip format to return content

- Support springboot configuration files

- Minimalist encapsulation call

down metodu - File Download

Şöyle yaparız

HttpUtil.down("https://gitee.com/admin4j/common-http","path/");

execute metodu

Örnek - get

Şöyle yaparız

# get
Response response=HttpRequest.get("https://search.gitee.com/?skin=rec&type=repository")
.queryMap(q,admin4j)
.header(HttpHeaderKey.USER_AGENT,admin4j)
.execute();

System.out.println(response = +response);

Örnek - post

Şöyle yaparız

# post form
Response response=HttpRequest.get("http://192.168.1.13:9100/auth/login")
.queryMap(q,admin4j)
.header(HttpHeaderKey.USER_AGENT,admin4j)
.form(username,admin)
.form(password,admin123)
.execute();

System.out.println(response = +response);

get metodu

Şöyle yaparız

Response response = HttpUtil.get("https://github.com/search", Pair.of(q, okhttp));
System.out.println(response =  + response);

post metodu

Şöyle yaparız

# JSON 
Response post = HttpUtil.post("https://...", "{...}");
System.out.println(post =  + post);

postForm metodu

Şöyle yaparız

# form 
Map<String, Object> formParams = new HashMap<>(16);
formParams.put("username", "admin");
formParams.put("password", "admin123");
Response response = HttpUtil.postForm("http://192.168.1.13:9100/auth/login",
                formParams
);
System.out.println(response =  + response);

upload metodu - File Upload

Şöyle yaparız

File file=new File(C:\\Sql.txt);
Map<String, Object> formParams=new HashMap<>();
formParams.put("key",test);
formParams.put("file",file);
formParams.put("token","...");
Response response=HttpUtil.upload("https://upload.qiniup.com/",formParams);
System.out.println(response);

HttpJsonUtil Sınıfı

Açıklaması şöyle

If the return format is JSON, you can use it to HttpJsonUtil automatically return JsonObject

get metodu

Şöyle yaparız

JSONObject object=HttpJsonUtil.get("https://github.com/search",
  Pair.of(q,http),
  Pair.of(username,agonie201218));

System.out.println(object = +object);

OkHttpClient.Builder Sınıfı

Örnek

Şöyle yaparız

@EnableRetrofitClients(basePackages = "com.oguzderici.retrofitdemo.clients")
@Configuration
public class RetrofitConfiguration {

  @Bean
  @LoadBalanced
  public OkHttpClient.Builder okHttpClientBuilder() {
    return new OkHttpClient.Builder()
      .addInterceptor(new HttpLoggingInterceptor()
                        .setLevel(HttpLoggingInterceptor.Level.BASIC));
    }
}
