/**
* SDK工具类,用来向服务端发送HTTP请求,请求支持POST/GET方式.
* 如果提供了AccessKey和SecurityKey参数信息,它能够在内部将请求消息进行签名处理,然后由CSB服务端进行验证.
*
*
*
* {@code
* import com.alibaba.csb.sdk.HttpCaller;
* import com.alibaba.csb.sdk.HttpCallerException;
* ...
*
* (1) 直接调用方式 (已过期,不推荐)
*
* Map params = new HashMap();
*
* Object smd = ... // 一个具体的复杂对象
* if (smd != null) {
* String data = JSON.toJSONString(smd); //转换为JSON String
* params.put("data", data);
* }
*
* // -- Tip: 如果调用者无法获得复杂对象参数类,则可以使用全map的方式设置json串,举例,对于json串
* // {"f1":{"f11":"v11", "f12":["v121","v122"]}, "f2":"wiseking"}
* // 它是可以通过如下的方式进行转换而来
* Map map = new HashMap();
*
* Map mapF1 = new HashMap();
* mapF1.put("f11", "v11");
* mapF1.put("f12", Arrays.asList("v121","v122"));
* map.put("f1", mapF1);
*
* map.put("f2", "wiseking");
* String jsonData = JSON.toJSONString(map);
* // -- Tip End
*
* params.put("name", "abcd"); //普通的串对象
* params.put("password", "abcd"); //普通的串对象
*
*
* String requestURL = "http://gateway.abc.com:8086/CSB";
* String API_NAME = "login_system";
* String version = "1.0.0";
* String ak = "xxxxxx";
* String sk = "xxxxxx"; //用户安全校验的签名密钥对
*
* try {
* String result = HttpCaller.doPost(requestURL, API_NAME, version, params, ak, sk);
*
* if (result != null) {
* //返回结果处理, 如转换为JSON对象
* ...
* }
* } catch (HttpCallerException ie) {
* //print error
* }}
*
* (2) 也可以使用第二种Builder的方式构造调用参数,然后进行调用 (推荐用法)
* import com.alibaba.csb.sdk.HttpParameters;
* import com.alibaba.csb.sdk.HttpCaller;
* import com.alibaba.csb.sdk.HttpCallerException;
*
* HttpParameters.Builder builder = HttpParameters.newBuilder();
*
* builder.requestURL("http://broker-ip:8086/CSB?arg0=123") // 设置请求的URL
* .api("test") // 设置服务名
* .version("1.0.0") // 设置版本号
* .method("get") // 设置调用方式, get/post
* .accessKey("ak").secretKey("sk"); // 设置accessKey 和 设置secretKey
*
* // 设置请求参数
* builder.putParamsMap("key1", "value1");
* builder.putParamsMap("key2", "{\"a\":value1}"); // json format value
*
* //设置请求调用方式
* builder.method("get");
*
* //设置透传的HTTP Headers
* builder.putHeaderParamsMap("header1", "value1");
* builder.putHeaderParamsMap("header2", "value2");
*
* //进行调用 返回结果
* String result = null;
* try {
* result = HttpCaller.invoke(builder.build());
*
* //注:如果返回结果出现乱码(不能正常显示中文),可以使用串字符集转换方法进行转换
* result = HttpCaller.changeCharset(result);
* } catch (HttpCallerException e) {
* // error process
* }
*
* try {
* // 重启设置请求参数
* builder.clearParamsMap();
* builder.putParamsMap("key1", "value1---new");
* builder.putParamsMap("key2", "{\"a\":\"value1-new\"}");
*
* // 使用post方式调用
* builder.method("post");
* HttpCaller.invoke(builder.build());
* } catch (HttpCallerException e) {
* // error process
* }
*
* (3) 如果使用json或者bytes内容的作为http body,使用下面的方法
*
* //构造ContentBody对象
* ContentBody cb = new ContentBody(jsonObject.toSring());
* //或者
* cb = new ContentBody(file2bytes);
*
* //ContentBody传递,要求使用post 方式进行调用
* //如果需要传递请求参数 可以拼接到请求URL中,或者设置paramsMap参数由SDK内部进行拼接
* HttpParameters.Builder builder = HttpParameters.newBuilder();
* builder.requestURL("http://broker-ip:8086/CSB?arg0=123") // 设置请求的URL,可以拼接URL请求参数
* .api("test") // 设置服务名
* .version("1.0.0") // 设置版本号
* .method("post") // 设置调用方式, 必须为 post
* .accessKey("ak").secretKey("sk"); // 设置accessKey 和 设置secretKey
*
* builder.contentBody(cb);
*
* //进行调用,返回结果
* String result = null;
* try {
* result = HttpCaller.invoke(builder.build());
* } catch (HttpCallerException e) {
* // error process
* }
*
*
* 高级功能
* 1. 设置代理地址
* String proxyHost = "...";
* int proxyPort = ...;
* HttpCaller.setProxyHost(proxyHost, proxyPort, null); //注意:本次设置只对本线程起作用
* ...
* HttpCaller.doPost(), doGet() or invoke();
*
* 2. 关于连接参数的设置:
* a. 可以为http/https设置以下的全局性系统参数:
* -Dhttp.caller.connection.max 设置连接池的最大连接数,默认是20
* -Dhttp.caller.connection.timeout 设置连接超时时间(毫秒),默认是-1, 永不超时
* -Dhttp.caller.connection.so.timeout 设置读取超时时间(毫秒),默认是-1, 永不超时
* -Dhttp.caller.connection.cr.timeout 设置从连接池获取连接实例的超时(毫秒),默认是-1, 永不超时
* -Dhttp.caller.connection.async 设置使用nio,默认fasle:同步io,true:nio
* -Dhttp.caller.skip.connection.pool 如何设置为true,则不使用连接池。默认行为是false,使用连接池(支持长连接)
* b. 也可以使用下面的方法设置以上的某一个或者多个参数:
* Map sysParams = new HashMap();
* sysParams.put("http.caller.connection.timeout","3000"); //设置连接超时为3秒
* HttpCaller.setConnectionParams(sysParams); //注意:本次设置只对本线程起作用
* ...
* HttpCaller.doPost(), doGet() or invoke();
