1，post-Body流和post参数，以下客户端代码和服务端代码可共用
客户端代码
?/**
????* post 方法
????* 抛送给EDI
????* @param url http://127.0.0.1:9003/api/edi/csm/csmReturnSubConBody?customerId=Fotile_CSM&api=csmreturnsub_confirm&id=6006
????* @param jsonParam xml报文结构
????* @return
????*/
???String httpPost45(String url, String jsonParam) {
//url?后面的即为post parmas 参数，bodu 放在数据流中进行传输
???????CloseableHttpClient httpclient = HttpClients.createDefault()
// ???????HttpGet httpGet = new HttpGet(url)
???????HttpPost post=new HttpPost(url)
???????//httpClient 4.5版本的超时参数配置
???????RequestConfig requestConfig = RequestConfig.custom()
???????????????.setConnectTimeout(50000).setConnectionRequestTimeout(50000)
???????????????.setSocketTimeout(50000).build()
???????post.setConfig(requestConfig)
???????//往BODY里填充数据主体
???????StringEntity entitys=new StringEntity(jsonParam.toString(), "utf-8")
???????entitys.setContentEncoding("UTF-8")
???????entitys.setContentType("application/xml")
???????post.setEntity(entitys)
???????HttpResponse response = httpclient.execute(post)
// ???????System.out.println("得到的结果:" + response.getStatusLine())//得到请求结果
???????String str = EntityUtils.toString(response.getEntity())//得到请求回来的数据
???????return str
???}
服务端代码
@ResponseBody
???@RequestMapping(value = "csmReturnSubConBody", method = RequestMethod.POST, produces = "application/xml")
???ResponseMessage csmReturnSubConBody(HttpServletRequest request, HttpServletResponse response,
???????????????????????????????????????@RequestParam Map<String, String> params) {
//params为客户端URL?后面的参数集，同理，也可以将bodu放到参数集里，进行传输
???????CustomerInfo customerInfo = erpSetting.getCustomerInfo(params.customerId as String)
???????if (!customerInfo) return
???????ApiInfo apiInfo = erpSetting.getApiInfo(customerInfo, params.api as String)
???????if (!apiInfo) return
???????String body = readBody(request)//这里去解析post流里的body数据
???????ResponseMessage rsp = csmSvc.convertBodyAndSendErpRetu(apiInfo, customerInfo, body, "xml", params.id as Object, null)
???????return rsp
???}
httpPost的两种方式
