java实现postman中用x-www-form-urlencoded参数的请求

首先，先给出postman的参数构造：

java代码实现（以post方法为例）：

PostMethod postMethod = new PostMethod(valueConfig.getImpsAuthUrl()) ;
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
//key  value 形式参数
NamevaluePair[] data = {
         new NamevaluePair("username","test"),
         new NamevaluePair("password","test123")
};
postMethod.setRequestBody(data);
HttpClient httpClient = new HttpClient();
int response = httpClient.executeMethod(postMethod); // 执行POST方法
String result = postMethod.getResponseBodyAsString() ;  //返回结果

if (response == 200 && result != null) {
		//成功后的逻辑
		doSth();
        log.info("获取请求,result={}", result);
}
