一、pom依賴

    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>fluent-hc</artifactId>
        <version>4.5.3</version>
    </dependency>

二、調(diào)用接口，塞入header和body

public Request bodyString(final String s, final ContentType contentType) 指定body的格式，body內(nèi)容需要是string

public void delete(){

        JSONObject content = new JSONObject();
        content.put("mode","delete");
        content.put("name","jiagou_mqtest.rabbitTest");
        content.put("vhost","/" );
        try {

          Request.Post(newUrl).bodyString(content.toString(), ContentType.APPLICATION_JSON).addHeader("authorization","Basic cmFiYml0bXE6cmFiYml0bXE=")
                  .execute().returnResponse().getStatusLine().getStatusCode();//獲取返回的狀態(tài)碼

            
        }catch(Exception e){
            e.printStackTrace();
        }
    }

body是表單(可參考http://blog.csdn.net/vector_yi/article/details/24298629)

    List forms = Form.form()
            .add("para1", para1)
            .add("para2", para2)
            .build();   
    Request.Post(uri).bodyForm(forms).execute().returnResponse().getStatusLine().getStatusCode();

Request.Post("http://blog.csdn.net/vector_yi")  
                .addHeader("X-Custom-header", "stuff")  
                .viaProxy(new HttpHost("myproxy", 8080))  
                .bodyForm(Form.form().add("username", "vip").add("password", "secret").build())  
                .execute().saveContent(new File("result.dump"));
