JAVA 实现POST（x-www-form-urlencoded）请求

平时都是喜欢用JSON，这种也是第一次。这两种的区别就是传递参数类型不一样。废话不多说，直接上代码

（1）、引入maven包

<dependency> <groupId>commons-httpclient</groupId> <artifactId>commons-httpclient</artifactId> <version>3.1</version> </dependency> （2）、代码实现

try {
    String postURL
    PostMethod postMethod = null;
    postMethod = new PostMethod(postURL) ;
    postMethod.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf-8") ;
//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("startTime",""),
            new NameValuePair("endTime","")
            
    };

    postMethod.setRequestBody(data);

    org.apache.commons.httpclient.HttpClient httpClient = new org.apache.commons.httpclient.HttpClient();
    int response = httpClient.executeMethod(postMethod); // 执行POST方法
    String result = postMethod.getResponseBodyAsString() ;

    return result;
} catch (Exception e) {
    logger.info("请求异常"+e.getMessage(),e);
    throw new RuntimeException(e.getMessage());
}

（3）、POSTMAN参数组装
