本文详细介绍了如何使用HttpClient进行远程接口调用，包括用户注册的步骤，如表单提交、HTTPClient工具的使用及响应处理。此外，还讲解了实名认证过程，特别是文件上传的实现，包括前端ajax提交、文件表单处理以及后端控制层和业务层的处理方法。

1、HttpClient远程接口调用

1)用户注册

用户注册

注册按钮button提交表单时，要return false

form表单

    <!-- action="http://localhost:8082/scw-restapi/member/regist" -->
    <form class="form-signin" role="form" action="${ctp}/member/regist"
        method="post" id="regForm">
    ...
    </form>

js提交表单

    $("#submitBtn").click(function() {

        var loginType = $("select.form-control").val();
        log("注册类型==============>", loginType)
        
        /* if (loginType == "管理") {
            $("#regForm").submit();
        } else {
            alert("此功能尚未开通");
        } */

        $("#regForm").submit();
        return false
    })

2)加载外部资源文件

app.properties

restapi.server.ip=127.0.0.1
restapi.server.port=8082
restapi.server.apppath=scw-restapi

编辑springmvc.xml

    <!-- 引入外部配置文件 -->
    <context:property-placeholder
        location="classpath:other/app.properties" />

RestApiServerInfo.java

    @Controller
    public class RestApiServerInfo {
    
        // MemberService memberService;
        @Value("${restapi.server.ip}")
        private String restapiserver;
    
        @Value("${restapi.server.port}")
        private String restapiport;
    
        @Value("${restapi.server.apppath}")
        private String appPath;
    
        public String getRestApiURL() {
            System.out.println("http://"   restapiserver   ":"   restapiport);
            return "http://"   restapiserver   ":"   restapiport   "/"   appPath;
        }
    }

3)HTTPClient工具远程调用接口

导入依赖

    <!-- https://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient -->
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.5.3</version>
    </dependency>

发送post请求

    public static String httpPostRequest(String url, Map<String, Object> params)

工具类HttpClientUtil.java
