java请求http post 接口是php写的 该怎么调用

[taodfhkdn]

这个是php调用：
$data='[{
"billNo": "UAT20095015",
"shopCode": "UAFH_CHN_99999",
"totalAmount": "369.00",
"billDate": "2017-11-19 14:00:00",
"reBillNo": "R20095007",
"reAmount": "369.00",
"createTime": "2017-12-10 14:00:00",
"reInvoice": "0",
"reQty":1
},
{
"billNo": "UAT20095014",
"shopCode": "UAFH_CHN_99999",
"totalAmount": "369.00",
"billDate": "2017-11-19 14:00:00",
"reBillNo": "R20095007",
"reAmount": "146.00",
"createTime": "2017-12-10 14:00:00",
"reInvoice": "1",
"reInvoiceQty": "1",
"reInvoiceAmount": "123.00",
"reInvoiceDetail": [{
"upc": 888376879075,
"qty": 1,
"finalUnitPrice": "123.00",
"finalTotalPrice": "123.00"
}],
"reQty":1
}
]';
$arr = array("appId" => $appId, "timestamp" => $timestamp,'accessToken'=>'996ba7c0e36bef395eb9d8a3dfe50463','data'=>$data);
$arr = sort_parms($arr);
$sign = get_sign($arr,$appKey);//这个地方是加密
/******退货单接受接口测试**********/
$arr['sign']=$sign;
// var_dump($arr);
url_post($arr);//php请求


//php请求
function url_post($param){
global $apiUrl;
$curl = curl_init();
//设置请求头
//设置抓取的url
curl_setopt($curl, CURLOPT_URL, $apiUrl);
//设置头文件的信息作为数据流输出
curl_setopt($curl, CURLOPT_HEADER, 1);
//设置获取的信息以文件流的形式返回，而不是直接输出。
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
//设置post方式提交
curl_setopt($curl, CURLOPT_POST, 1);
//设置post数据
// var_dump($param);die;
curl_setopt($curl, CURLOPT_POSTFIELDS, $param);
//执行命令
$data = curl_exec($curl);
//关闭URL请求
curl_close($curl);
//显示获得的数据
print_r($data);
}
我想问的是java该怎么去把这些参数传输过去，请求该怎么写呢

无非是设置header，然后post提交数据

public static String tune1(String str4，Sting path) throws IOException{ String time= String.valueOf(System.currentTimeMillis()); String urlPath =path; //String param="sign="+URLDecoder.decode(HMAC.sign(),"UTF-8")+"&appId="+URLEncoder.encode("app001","UTF-8")+"×tamp="+HMAC.times; String param="appId="+URLEncoder.encode("app001","UTF-8")+"&sign="+URLDecoder.decode(HMAC.Sign1(str4,Interface.token),"UTF-8")+"×tamp="+URLEncoder.encode(time,"UTF-8")+"&accessToken="+URLEncoder.encode(Interface.token,"UTF-8")+"&data:"+URLDecoder.decode(str4,"UTF-8"); System.out.println(param+"参数"); String token=""; //建立连接 URL url=new URL(urlPath); HttpURLConnection httpConn=(HttpURLConnection)url.openConnection(); //设置参数 httpConn.setDoOutput(true); //需要输出 httpConn.setDoInput(true); //需要输入 httpConn.setUseCaches(false); //不允许缓存 httpConn.setRequestMethod("POST"); //设置POST方式连接 httpConn.setConnectTimeout(15000); //设置请求属性 httpConn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded"); httpConn.setRequestProperty("Connection", "Keep-Alive");// 维持长连接 httpConn.setRequestProperty("Charset", "UTF-8"); //连接,也可以不用明文connect，使用下面的httpConn.getOutputStream()会自动connect // httpConn.connect(); //建立输入流，向指向的URL传入参数 // DataOutputStream dos=new DataOutputStream(httpConn.getOutputStream()); PrintWriter pw=new PrintWriter(httpConn.getOutputStream()); //dos.writeBytes(param); //dos.flush(); //dos.close(); pw.print(param); pw.flush(); pw.close(); //获得响应状态 int resultCode=httpConn.getResponseCode(); if(HttpURLConnection.HTTP_OK==resultCode){ StringBuffer sb=new StringBuffer(); String readLine=new String(); 我是这样写的 对么 BufferedReader responseReader=new BufferedReader(new InputStreamReader(httpConn.getInputStream(),"UTF-8")); while((readLine=responseReader.readLine())!=null){ sb.append(readLine); } responseReader.close(); token=sb.toString(); System.out.println(token); } return token; 我是这样写的。对么 不对的话需要改哪里呢
