34.10. android Oauth2 + Jwt exampleOauth 返回数据，通过 Gson 的 fromJson 存储到下面类中。

package cn.netkiller.okhttp.pojo; public class Oauth { private String access_token; private String token_type; private String refresh_token; private String expires_in; private String scope; private String jti; public String getAccess_token() { return access_token; }public void setAccess_token(String access_token) { this.access_token = access_token; }public String getToken_type() { return token_type; }public void setToken_type(String token_type) { this.token_type = token_type; }public String getRefresh_token() { return refresh_token; }public void setRefresh_token(String refresh_token) { this.refresh_token = refresh_token; }public String getExpires_in() { return expires_in; }public void setExpires_in(String expires_in) { this.expires_in = expires_in; }public String getScope() { return scope; }public void setScope(String scope) { this.scope = scope; }public String getJti() { return jti; }public void setJti(String jti) { this.jti = jti; }@Override public String toString() { return "Oauth{" + "access_token=‘" + access_token + ‘‘‘ + ", token_type=‘" + token_type + ‘‘‘ + ", refresh_token=‘" + refresh_token + ‘‘‘ + ", expires_in=‘" + expires_in + ‘‘‘ + ", scope=‘" + scope + ‘‘‘ + ", jti=‘" + jti + ‘‘‘ + ‘}‘; } }

Activity 文件

package cn.netkiller.okhttp; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.util.Log; import android.widget.TextView; import com.google.gson.Gson; import java.io.IOException; import cn.netkiller.okhttp.pojo.Oauth; import okhttp3.Authenticator; import okhttp3.Call; import okhttp3.Callback; import okhttp3.Credentials; import okhttp3.FormBody; import okhttp3.OkHttpClient; import okhttp3.Request; import okhttp3.RequestBody; import okhttp3.Response; import okhttp3.Route; public class Oauth2jwtActivity extends AppCompatActivity {private TextView token; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_oauth2jwt); token = (TextView) findViewById(R.id.token); try { get(); } catch (IOException e) { e.printStackTrace(); }}public static Oauth accessToken() throws IOException {OkHttpClient client = new OkHttpClient.Builder().authenticator( new Authenticator() { public Request authenticate(Route route, Response response) { String credential = Credentials.basic("api", "secret"); return response.request().newBuilder().header("Authorization", credential).build(); } } ).build(); String url = "https://api.netkiller.cn/oauth/token"; RequestBody formBody = new FormBody.Builder() .add("grant_type", "password") .add("username", "blockchain") .add("password", "123456") .build(); Request request = new Request.Builder() .url(url) .post(formBody) .build(); Response response = client.newCall(request).execute(); if (!response.isSuccessful()) { throw new IOException("服务器端错误: " + response); }Gson gson = new Gson(); Oauth oauth = gson.fromJson(response.body().string(), Oauth.class); Log.i("oauth", oauth.toString()); return oauth; }public void get() throws IOException {OkHttpClient client = new OkHttpClient.Builder().authenticator( new Authenticator() { public Request authenticate(Route route, Response response) throws IOException { return response.request().newBuilder().header("Authorization", "Bearer " + accessToken().getAccess_token()).build(); } } ).build(); String url = "https://api.netkiller.cn/misc/compatibility"; Request request = new Request.Builder() .url(url) .build(); client.newCall(request).enqueue(new Callback() { @Override public void onFailure(Call call, IOException e) { call.cancel(); }@Override public void onResponse(Call call, Response response) throws IOException {final String myResponse = response.body().string(); runOnUiThread(new Runnable() { @Override public void run() { Log.i("oauth", myResponse); token.setText(myResponse); } }); } }); } public void post() throws IOException {OkHttpClient client = new OkHttpClient.Builder().authenticator( new Authenticator() { public Request authenticate(Route route, Response response) throws IOException { return response.request().newBuilder().header("Authorization", "Bearer " + accessToken().getAccess_token()).build(); } } ).build(); String url = "https://api.netkiller.cn/history/create"; String json = "{ " + ""assetsId": "5bced71c432c001c6ea31924", " + ""title": "添加信息", " + ""message": "信息内容", " + ""status": "录入" " + "}"; final MediaType JSON = MediaType.parse("application/json; charset=utf-8"); RequestBody body = RequestBody.create(JSON, json); Request request = new Request.Builder() .url(url) .post(body) .build(); client.newCall(request).enqueue(new Callback() { @Override public void onFailure(Call call, IOException e) { call.cancel(); }@Override public void onResponse(Call call, Response response) throws IOException {final String myResponse = response.body().string(); runOnUiThread(new Runnable() { @Override public void run() {//Gson gson = new Gson(); //Oauth oauth = gson.fromJson(myResponse, Oauth.class); //Log.i("oauth", oauth.toString()); token.setText(myResponse); } }); } }); }}

上面的例子演示了，怎样获取 access token 以及 HTTP 基本操作 GET 和 POST，再Restful接口中还可能会用到 PUT, DELETE 等等，原来相同，这里就不在演示。
34.11. HTTP/2首先确认你的服务器是支持 HTTP2，HTTP2配置方法可以参考《Netkiller Web 手札》
下面是我的例子仅供参考，nginx 开启 http2 代理后面的 Spring Cloud 接口。

server { listen80; listen 443 ssl http2; server_nameapi.netkiller.cn; ssl_certificate ssl/netkiller.cn.crt; ssl_certificate_key ssl/netkiller.cn.key; ssl_session_cache shared:SSL:20m; ssl_session_timeout 60m; charset utf-8; access_log/var/log/nginx/api.netkiller.cn.access.log; error_page497https://$host$uri?$args; if ($scheme = http) { return 301 https://$server_name$request_uri; }location / { proxy_passhttp://127.0.0.1:8000; proxy_http_version 1.1; proxy_set_headerHost$host; proxy_set_headerX-Forwarded-For $proxy_add_x_forwarded_for; }#error_page404/404.html; # redirect server error pages to the static page /50x.html # error_page500 502 503 504/50x.html; location = /50x.html { root/usr/share/nginx/html; }# deny access to .htaccess files, if Apache‘s document root # concurs with nginx‘s one # #location ~ /.ht { #denyall; #} }

安卓程序如下

String url = "https://api.netkiller.cn/member/json"; OkHttpClient client = new OkHttpClient(); Request request = new Request.Builder().url(url).build(); client.newCall(request).enqueue(new Callback() { @Override public void onFailure(Call call, IOException e) { Log.d("okhttp", "Connect timeout. " + e.getMessage()); }@Override public void onResponse(Call call, Response response) throws IOException { String text = response.body().string(); Log.d("okhttp", "HTTP Code " + response.code() + " TEXT " + text); Log.d("okhttp", "Protocol: " + response.protocol()); } });

运行结果

D/okhttp: HTTP Code 200 TEXT {"status":false,"reason":"","code":0,"data":{"id":null,"username":"12322228888","mobile":"12322228888","password":"123456","wechat":"微信ID","role":"Organization","captcha":null,"createDate":"2018-10-25 09:25:23","updateDate":null}} Protocol: h2

输出 h2 表示当前接口与服务器连接是通过 http2 完成。
Oauth2 + Jwt 的 SpringBoot 实现方法可以参考作者的《Netkiller Spring Cloud 手札》
