在Java開發(fā)中,模擬Postman發(fā)送x-www-form-urlencoded類型的請求是一個常見需求,本文主要介紹了如何在Java中實現(xiàn)這一功能,首先,需要通過導(dǎo)入http-client包來創(chuàng)建HTTP客戶端,接著,利用該客戶端發(fā)送Post請求

java postman用x-www-form-urlencoded參數(shù)的請求

首先，先給出postman的參數(shù)構(gòu)造：

java代碼實現(xiàn)（以post方法為例）

PostMethod postMethod = new PostMethod(valueConfig.getImpsAuthUrl()) ;
postMethod.setRequestHeader("Content-Type", "application/x-www-form-urlencoded;charset=utf-8") ;
//參數(shù)設(shè)置，需要注意的就是里邊不能傳NULL，要傳空字符串
//key  value 形式參數(shù)
NameValuePair[] data = {
         new NameValuePair("username","test"),
         new NameValuePair("password","test123")
};
postMethod.setRequestBody(data);
HttpClient httpClient = new HttpClient();
int response = httpClient.executeMethod(postMethod); // 執(zhí)行POST方法
String result = postMethod.getResponseBodyAsString() ;  //返回結(jié)果

if (response == 200 && result != null) {
		//成功后的邏輯
		doSth();
        log.info("獲取請求,result={}", result);
}

java實現(xiàn)postman為x-www-form-urlencoded的調(diào)用

客戶端實現(xiàn)

導(dǎo)入http-client jar。

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

public static void clientDemo() {
        try {
            String requestUrl = "http://hello/demo";
            PostMethod postMethod = new PostMethod(requestUrl);

            String data = "json_json_json_json";
            StringRequestEntity stringRequestEntity = new StringRequestEntity(data, "application/x-www-form-urlencoded", "utf-8");
            postMethod.setRequestEntity(stringRequestEntity);

            org.apache.commons.httpclient.HttpClient httpClient = new org.apache.commons.httpclient.HttpClient();

            //調(diào)用接口
            int code = httpClient.executeMethod(postMethod);
            String result = postMethod.getResponseBodyAsString();

            System.out.println("接口狀態(tài)" + code);
            System.out.println("響應(yīng)" + result);
        } catch (Exception e) {
            throw new RuntimeException(e.getMessage());
        }
    }

服務(wù)端實現(xiàn)

@RequestMapping(value = "/receive", method = RequestMethod.POST)
    @ResponseBody
    public String receiveFare(@RequestBody String str) {
        System.out.println("接到數(shù)據(jù):" + str);
        return "ok";
    }
