微信支付报错提示“商户号该产品权限未开通，请前往商户平台>产品中心检查后重试

时间：2024-01-01

微信开发的时候可能会出现如题问题，这是因为没有在微信商户平台开放对应的产品权限。

一、问题

如下，模拟一个native支付，报出了如题异常

     private String appid="";
     private String mchId="";
     private String native_pay="";   
     private String notifyurl="";
     public String createWxNativeNativeOrder(String orderName,String orderNo,int orderAmount) {
		
		// 请求URL
		HttpPost httpPost = new HttpPost(native_pay);
		WxNativePayModel wx = new WxNativePayModel();
		WxNativePayModelAmount w = new WxNativePayModelAmount();
		w.setTotal(orderAmount);
		wx.setAmount(w);
		wx.setAppid(appid);
		wx.setMchid(mchId);
		wx.setDescription(orderName);
		wx.setNotify_url(notifyurl);
		wx.setOut_trade_no(orderNo);
		StringEntity entity = new StringEntity(MyUtils.toJson(wx), "utf-8");
		entity.setContentType("application/json");
		httpPost.setEntity(entity);
		httpPost.setHeader("Accept", "application/json");
		// 完成签名并执行请求
		CloseableHttpResponse response = null;
		int statusCode=-1;
		try {
			this.setup();
			response = httpClient.execute(httpPost);
			statusCode = response.getStatusLine().getStatusCode();
			if (statusCode == 200) {
				System.out.println("success,return body = " + EntityUtils.toString(response.getEntity()));
			} else if (statusCode == 204) {
				System.out.println("success");
			} 
			wx.setResult( EntityUtils.toString(response.getEntity()));
		} catch (Exception e) {
			wx.setResult(e.getMessage());
		} finally {
			try {
				if(MyUtils.isNotNull(response)) {
					response.close();		
				}
				if(MyUtils.isNotNull(httpClient)) {
					httpClient.close();	
				}
			} catch (IOException e) {
				wx.setResult(e.getMessage());
		
			}
		}
		System.out.println(MyUtils.toJson(wx));
		return wx.getResult();
	}

二、原因

进入商户平台，找到产品大全，找到对应的支付类型（native是给出二维码，扫码支付），即产品类型，点击开通即可。

注意，如果无法开通，可能是一些权限或认证没有搞定。
