34.10. Android Oauth2 + Jwt example

Oauth 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 + '\'' +
                '}';
    }

        });
    }

}

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 {
    listen       80;
    listen 443 ssl http2;
    server_name  api.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_page  497              https://$host$uri?$args;

    if ($scheme = http) {
        return 301 https://$server_name$request_uri;
    }

    location / {
		proxy_pass   http://127.0.0.1:8000;
        proxy_http_version 1.1;
		proxy_set_header    Host    $host;
		proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;	
    }

    #error_page  404              /404.html;

    # redirect server error pages to the static page /50x.html
    #
    error_page   500 502 503 504  /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 {
    #    deny  all;
    #}
}

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》
