post 两种方式 application/x-www-form-urlencoded和multipart/form-data

本次主要涉及 application/x-www-form-urlencoded方式。

postman访问方式如图：

 

 

 

 

 

java代码实现：

首先使用maven作为第三方依赖管理：

　　

   <dependencies>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>fastjson</artifactId>
            <version>1.2.57</version>
        </dependency>
        <dependency>
            <groupId>commons-httpclient</groupId>
            <artifactId>commons-httpclient</artifactId>
            <version>3.1</version>
        </dependency>
    </dependencies>

　

实现的方法块：

 public static FullText fullTextSearch(String token, HashMap<String, String> bodyMap) {
        headers.put("token", token);

        try {
            PostMethod postMethod = new PostMethod(api);   //api为访问的url

            for (Map.Entry<String, String> header : headers.entrySet()) {
                postMethod.setRequestHeader(header.getKey(), header.getValue());
            }

            int size = bodyMap.size();
            int index = 0;
            NameValuePair[]  body = new NameValuePair[size];
            for (Map.Entry<String, String> bodyItem : bodyMap.entrySet()) {
                body[index++] = new NameValuePair(bodyItem.getKey(), bodyItem.getValue());
            }
            postMethod.setRequestBody(body);

            HttpClient httpClient = new HttpClient();
            int response = httpClient.executeMethod(postMethod); // 执行POST方法 正常返回200
            String result = postMethod.getResponseBodyAsString();
            FullText fullText = JSON.parseObject(result, FullText.class);

            return fullText;
        } catch (Exception e) {
            throw new RuntimeException(e.getMessage());
        }
    }
