調了好久終於搞定了 總結一下

後臺程式碼  為兩種 一種封裝bean 一種直接傳形參 後臺框架為SSM框架

	/*
	 * 提交意見
	 * 
	 */
	@RequestMapping(value = "giveAdvice", method = RequestMethod.POST)
	@ResponseBody
	public Integer giveAdvice(@RequestBody Advice advice) {
		System.out.println(advice);
		System.out.println("=========================" + advice.getUserId() + "================" + advice.getAdviceMsg());
		return adviceService.giveAdvice(advice);
	}

	// 提交意見2
	@RequestMapping(value = "giveAdvice2", method = RequestMethod.POST)
	@ResponseBody
	public Integer giveAdvice2(String UserId, String AdviceMsg) {
		// System.out.println(advice);
		System.out.println("=========================" + UserId + "================" + AdviceMsg);
		return adviceService.giveAdvice2(UserId, AdviceMsg);
	}
 

一、當小程式請求header為 'content-type': 'application/json' 時

      wx.request({
        url: appUrl+'/giveAdvice',
        data: {
          "UserId":app.globalData.userId,
          "AdviceMsg":advice
        },
        header: {
          'content-type': 'application/json'
        },
        method: "POST",
        success(res){
          console.log(res);
        }
      })
    }
 

結果第一種giveAdvice API LOG資訊為

 "=========================null================null”

新增失敗

giveAdvice 2 API LOG資訊為  "=========================null================null”

新增失敗

二、當小程式請求header為 'content-type': 'application/x-www-form-urlencoded'時

第一種 giveAdvice API log資訊為 

DEBUG [http-nio-8080-exec-4] - Returning cached instance of singleton bean 'mobileController'
DEBUG [http-nio-8080-exec-4] - Resolving exception from handler [public java.lang.Integer com.smartcharger.controller.MobileC
ontroller.giveAdvice(com.smartcharger.pojo.Advice)]: org.springframework.web.HttpMediaTypeNotSupportedException: Content type
 'application/x-www-form-urlencoded;charset=UTF-8' not supported
DEBUG [http-nio-8080-exec-4] - Resolving exception from handler [public java.lang.Integer com.smartcharger.controller.MobileC

 'application/x-www-form-urlencoded;charset=UTF-8' not supported
DEBUG [http-nio-8080-exec-4] - Null ModelAndView returned to DispatcherServlet with name 'SmartCharger': assuming HandlerAdap
ter completed request handling
DEBUG [http-nio-8080-exec-4] - Successfully completed request
 

新增失敗

第二種 giveAdvice2 API log資訊為

新增成功！！！！！！！

終於成功了！！！！

結論 小程式的POST請求設定

header: {

          'content-type': 'application/x-www-form-urlencoded'

 }

後臺API介面 格式為

	@RequestMapping(value = "giveAdvice2", method = RequestMethod.POST)
	@ResponseBody
	public Integer giveAdvice2(String UserId, String AdviceMsg) {
		// System.out.println(advice);
		System.out.println("=========================" + UserId + "================" + AdviceMsg);
		return adviceService.giveAdvice2(UserId, AdviceMsg);
	}

即可接收POST請求資訊！！！

除錯了2個小時終於有結果了 挖坑！！！
