下载了支付DEMO其实有些地方不对的,比如如果做沙盒测试的时候,需要使用getsignkey,而官方的demo中没有这个.
看了看sf.gg的一个文章,之后把获取getsignkey的api请求加了进去.
现在的 WXPayConstants :
package com.wechat.demo.wxpay; import org.apache.http.client.HttpClient; /**
* 微信支付常量类
*/
public class WXPayConstants { public enum SignType {
MD5, HMACSHA256
} public static final String DOMAIN_API = "api.mch.weixin.qq.com";
public static final String DOMAIN_API2 = "api2.mch.weixin.qq.com";
public static final String DOMAIN_APIHK = "apihk.mch.weixin.qq.com";
public static final String DOMAIN_APIUS = "apius.mch.weixin.qq.com"; public static final String FAIL = "FAIL";
public static final String SUCCESS = "SUCCESS";
public static final String HMACSHA256 = "HMAC-SHA256";
public static final String MD5 = "MD5"; public static final String FIELD_SIGN = "sign";
public static final String FIELD_SIGN_TYPE = "sign_type"; public static final String WXPAYSDK_VERSION = "WXPaySDK/3.0.9";
public static final String USER_AGENT = WXPAYSDK_VERSION +
" (" + System.getProperty("os.arch") + " " + System.getProperty("os.name") + " " + System.getProperty("os.version") +
") Java/" + System.getProperty("java.version") + " HttpClient/" + HttpClient.class.getPackage().getImplementationVersion(); //提交付款码支付 https://pay.weixin.qq.com/wiki/doc/api/micropay.php?chapter=9_10&index=1
public static final String MICROPAY_URL_SUFFIX = "/pay/micropay";

public static final String REVERSE_URL_SUFFIX = "/secapi/pay/reverse";
//关闭订单 https://pay.weixin.qq.com/wiki/doc/api/native.php?chapter=9_3
public static final String CLOSEORDER_URL_SUFFIX = "/pay/closeorder";
//申请退款 https://pay.weixin.qq.com/wiki/doc/api/native.php?chapter=9_4
public static final String REFUND_URL_SUFFIX = "/secapi/pay/refund";
//查询退款 https://pay.weixin.qq.com/wiki/doc/api/native.php?chapter=9_5

public static final String SHORTURL_URL_SUFFIX = "/tools/shorturl";
//授权码查询openid https://pay.weixin.qq.com/wiki/doc/api/micropay.php?chapter=9_13&index=9
public static final String AUTHCODETOOPENID_URL_SUFFIX = "/tools/authcodetoopenid"; // sandbox 沙盒测试
public static final String SANDBOX_GETSIGNKEY_URL_SUFFIX = "/sandboxnew/pay/getsignkey";
public static final String SANDBOX_MICROPAY_URL_SUFFIX = "/sandboxnew/pay/micropay";
public static final String SANDBOX_UNIFIEDORDER_URL_SUFFIX = "/sandboxnew/pay/unifiedorder";
public static final String SANDBOX_ORDERQUERY_URL_SUFFIX = "/sandboxnew/pay/orderquery";

public static final String SANDBOX_SHORTURL_URL_SUFFIX = "/sandboxnew/tools/shorturl";
public static final String SANDBOX_AUTHCODETOOPENID_URL_SUFFIX = "/sandboxnew/tools/authcodetoopenid"; }
请注意上面红色的代码是请求沙盒测试需要的key的请求路径.
之后把请求的方法写到了原来的 WXPayUtil 中:
/**
* 获取sandbox测试需要的signkey
* @param config
* @param wxPay
* @return
* @throws Exception
*/
public static String retrieveSandboxSignKey(IWXPayConfig config, WXPay wxPay) throws Exception {
try {
Map<String, String> params = new HashMap<String, String>();
params.put("mch_id", config.getMchID());
params.put("nonce_str", WXPayUtil.generateNonceStr());
params.put("sign", generateSignatrue(params, config.getKey()));
String strXML = wxPay.requestWithoutCert(WXPayConstants.SANDBOX_GETSIGNKEY_URL_SUFFIX, params, config.getHttpConnectTimeoutMs(), config.getHttpReadTimeoutMs());
if (StringUtils.isBlank(strXML)) {
return null;
}
Map<String, String> result = WXPayUtil.xmlToMap(strXML);
getLogger().info("retrieveSandboxSignKey:" + result);
if ("SUCCESS".equals(result.get("return_code"))) {
return result.get("sandbox_signkey");
}
return null;
}catch(Exception e){
getLogger().info("获取Sandbox_signkey异常",e);
return null;
} }
在这之后就可以根据DEMO中的README去设置一下了.
这里还有官方提供的测试用例:
测试用例的作用是测试支付的传参与返回数据是否正确.
测试了官方支付DEMO后,可以再根据官方的测试用例文档进行相应地处理.
由于现有公司使用的微信平台对接一套php系统,所以暂时没有找到更稳妥的在线测试.
只能进行模拟的测试+后期业务逻辑编写了.
调起支付(需要对接开通支付的微信服务号),现调不起支付也不要紧,只需要按照调起支付
后续编写逻辑代码即可.
