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());
         }
     }
