摘要

举例三种请求：

1. http的GET请求（application/json）
2. http的POST请求（application/json）
3. http的POST请求（application/x-www-form-urlencoded）

依赖

<!--httpclient-->
        <dependency>
            <groupId>commons-httpclient</groupId>
            <artifactId>commons-httpclient</artifactId>
            <version>3.1</version>
        </dependency>

第一种：http的GET请求（application/json）

HttpHeaders headers = new HttpHeaders();
        headers.set("token", token);
        headers.set("Content-Type", "application/json");
        HttpEntity requestEntity = new HttpEntity(headers);
        ResponseEntity<Response> response = restTemplate.exchange(address + "/dolphinscheduler/projects/query-project-list", HttpMethod.GET, requestEntity, Response.class);

第二种：http的POST请求（application/json）

HttpHeaders headers = new HttpHeaders();
        headers.set("token", token);
        headers.set("Content-Type", "application/json");
        HttpEntity requestEntity = new HttpEntity(projectDto, headers);
        restTemplate.exchange(address + "/dolphinscheduler/projects/create", HttpMethod.POST, requestEntity, Response.class);

第三种：http的POST请求（application/x-www-form-urlencoded）

String postURL = address + "/dolphinscheduler/projects/create";
            PostMethod postMethod = new PostMethod(postURL) ;
            postMethod.setRequestHeader("Content-Type",
                    "application/x-www-form-urlencoded;charset=utf-8") ;
            postMethod.setRequestHeader("token", token);
            //参数设置，需要注意的就是里边不能传NULL，要传空字符串
            NameValuePair[] data = {
                    new NameValuePair("projectName",projectDto.getProjectName()),
                    new NameValuePair("description",projectDto.getDescription())
            };
            postMethod.setRequestBody(data);
            org.apache.commons.httpclient.HttpClient httpClient = new org.apache.commons.httpclient.HttpClient();
            httpClient.executeMethod(postMethod);
            JSONObject result = JSONObject.parseObject(postMethod.getResponseBodyAsString());
