OKhttp3使用get,post,delete,patch四种请求
1.okhttp简介
okhttp封装了大量http操作,大大简化了安卓网络请求操作,是现在最火的安卓端轻量级网络框架。如今okhttp已经更新到了okhttp4.0, 支持Android5.0以及以上的版本,要求Java在8.0以及以上的版本。
2.okhttp安装
-
可以通过添加依赖进行安装
implementation("com.squareup.okhttp3:okhttp:4.7.2")
-
可以通过JAR的方式进行安装,
https://github.com/square/okhttp/
-
如果使用的是androidStudio可以在Project Structure--->Dependencies 点击“+”号选Library dependency在搜索页面分别搜okttp,okio
3.okhttp使用
3.1get请求
这里提供官方给的例子
OkHttpClient client = new OkHttpClient();
String run(String url) throws IOException {
Request request = new Request.Builder()
.url(url)
.build();
try (Response response = client.newCall(request).execute()) {
return response.body().string();
}
}
3.2POST请求
同样提供官方给的例子
ublic static final MediaType JSON
= MediaType.get("application/json; charset=utf-8");
OkHttpClient client = new OkHttpClient();
String post(String url, String json) throws IOException {
RequestBody body = RequestBody.create(json, JSON);
Request request = new Request.Builder()
.url(url)
.post(body)
.build();
try (Response response = client.newCall(request).execute()) {
return response.body().string();
}
}
3.3delete请求
public class DeleteApi {
private OkHttpClient client;
public void Delete(final Handler handler, final String url, final int what){
final String token = TokenPool.getTokenPool().UserToken;
client = new OkHttpClient();
new Thread(){
@Override
public void run() {
super.run();
try {
String result = getUrl(url,token);
// Log.d("TAG",result);
Message message1 = Message.obtain();
message1.what=what;
message1.obj = result;
handler.sendMessage(message1);
} catch (IOException e) {
e.printStackTrace();
}
}
}.start();
}
String getUrl(String url,String token) throws IOException {
FormBody body = new FormBody.Builder().build();
Request request = new Request.Builder()
.url(url)
.delete(body)
.addHeader("Authorization","Bearer "+token)
.build();
try (Response response = client.newCall(request).execute()) {
return response.body().string();
}
}
}
3.4patch请求
public class PatchApi {
private OkHttpClient client;
private MediaType mediaType
= MediaType.parse("application/json; charset=utf-8");
public void patch(final Handler handler,final String url,final RequestBody body, final int what){
final String token = TokenPool.getTokenPool().UserToken;
client = new OkHttpClient();
new Thread(){
@Override
public void run() {
super.run();
try {
String result = getUrl(url,body,token);
Message message1 = Message.obtain();
message1.what= what;
message1.obj = result;
handler.sendMessage(message1);
} catch (IOException e) {
e.printStackTrace();
}
}
}.start();
}
String getUrl(String url, RequestBody body, String token) throws IOException {
Request request = new Request.Builder()
.url(url)
.addHeader("Authorization","Bearer "+token)
.patch(body)
.build();
try (Response response = client.newCall(request).execute()) {
return response.body().string();
}
}
}
