3.2. API接入(含示例代碼)
本章節(jié)展示了如何使用微信支付服務(wù)端 SDK 快速接入小程序支付產(chǎn)品，完成與微信支付對接的部分。
注意：
文檔中的代碼示例是用來闡述 API 基本使用方法，代碼中的示例參數(shù)需替換成商戶自己賬號及請求參數(shù)才能跑通。
以下接入步驟僅提供參考，請商戶結(jié)合自身業(yè)務(wù)需求進(jìn)行評估、修改。
3.2.1. 【服務(wù)端】小程序支付統(tǒng)一下單
步驟說明：用戶通過商戶小程序進(jìn)入商戶網(wǎng)頁，當(dāng)用戶選擇相關(guān)商品購買時，商戶系統(tǒng)先調(diào)用該接口在微信支付服務(wù)后臺生成預(yù)支付交易單。

重要參數(shù)說明：
? out_trade_no：商戶系統(tǒng)內(nèi)部訂單號，只能是數(shù)字、大小寫字母_-*且在同一個商戶號下唯一
? description：商品描述
? notify_url：支付回調(diào)通知URL，該地址必須為直接可訪問的URL，不允許攜帶查詢串
? total：訂單總金額，單位為分
? openid：openid是微信用戶在appid下的唯一用戶標(biāo)識(appid不同，則獲取到的openid就不同)，可用于永久標(biāo)記一個用戶。openid獲取方式請參考以下文檔
小程序獲取openid、
公眾號獲取openid、
APP獲取openid、
更多參數(shù)、響應(yīng)詳情及錯誤碼請參見JSAPI下單接口文檔
3.2.2.【客戶端】小程序調(diào)起支付API
步驟說明：通過JSAPI下單成功獲取預(yù)支付交易會話標(biāo)識(prepay_id)后，需要通過小程序調(diào)起支付API來調(diào)起微信支付收銀臺
注意：
此API需要將請求參數(shù)進(jìn)行簽名(參與簽名的參數(shù)為：appId、timeStamp、nonceStr、package，參數(shù)區(qū)分大小寫)
appId必須為最后拉起收銀臺的小程序appid
示例代碼：
wx.requestPayment(
{
"timeStamp": "1414561699",
"nonceStr": "5K8264ILTKCH16CQ2502SI8ZNMTM67VS",
"package": "prepay_id=wx201410272009395522657a690389285100",
"signType": "RSA",
"paySign": "oR9d8PuhnIc+YZ8cBHFCwfgpaK9gd7vaRvkYD7rthRAZ\/X+QBhcCYL21N7cHCTUxbQ+EAt6Uy+lwSN22f5YZvI45MLko8Pfso0jm46v5hqcVwrk6uddkGuT+Cdvu4WBqDzaDjnNa5UK3GfE1Wfl2gHxIIY5lLdUgWFts17D4WuolLLkiFZV+JSHMvH7eaLdT9N5GBovBwu5yYKUR7skR8Fu+LozcSqQixnlEZUfyE55feLOQTUYzLmR9pNtPbPsu6WVhbNHMS3Ss2+AehHvz+n64GDmXxbX++IOBvm2olHu3PsOUGRwhudhVf7UcGcunXt8cqNjKNqZLhLw4jq\/xDg==",
"success":function(res){},
"fail":function(res){},
"complete":function(res){}
})
? package：統(tǒng)一下單接口返回的prepay_id參數(shù)值，提交格式如：prepay_id=***
? signType：該接口V3版本僅支持RSA
? paySign：簽名

3.2.3.【服務(wù)端】接收支付結(jié)果通知
步驟說明：當(dāng)用戶完成支付，微信會把相關(guān)支付結(jié)果將通過異步回調(diào)的方式通知商戶，商戶需要接收處理，并按文檔規(guī)范返回應(yīng)答
注意：
支付結(jié)果通知是以POST 方法訪問商戶設(shè)置的通知url，通知的數(shù)據(jù)以JSON 格式通過請求主體(BODY)傳輸。通知的數(shù)據(jù)包括了加密的支付結(jié)果詳情
加密不能保證通知請求來自微信。微信會對發(fā)送給商戶的通知進(jìn)行簽名，并將簽名值放在通知的HTTP頭Wechatpay-Signature。商戶應(yīng)當(dāng)驗(yàn)證簽名，以確認(rèn)請求來自微信，而不是其他的第三方。簽名驗(yàn)證的算法請參考微信支付API v3簽名方案
支付通知http應(yīng)答碼為200或204才會當(dāng)作正常接收，當(dāng)回調(diào)處理異常時，應(yīng)答的HTTP狀態(tài)碼應(yīng)為500，或者4xx
商戶成功接收到回調(diào)通知后應(yīng)返回成功的http應(yīng)答碼為200或204
同樣的通知可能會多次發(fā)送給商戶系統(tǒng)。商戶系統(tǒng)必須能夠正確處理重復(fù)的通知。 推薦的做法是，當(dāng)商戶系統(tǒng)收到通知進(jìn)行處理時，先檢查對應(yīng)業(yè)務(wù)數(shù)據(jù)的狀態(tài)，并判斷該通知是否已經(jīng)處理。如果未處理，則再進(jìn)行處理；如果已處理，則直接返回結(jié)果成功。在對業(yè)務(wù)數(shù)據(jù)進(jìn)行狀態(tài)檢查和處理之前，要采用數(shù)據(jù)鎖進(jìn)行并發(fā)控制，以避免函數(shù)重入造成的數(shù)據(jù)混亂
對后臺通知交互時，如果微信收到商戶的應(yīng)答不符合規(guī)范或超時，微信認(rèn)為通知失敗，微信會通過一定的策略定期重新發(fā)起通知，盡可能提高通知的成功率，但微信不保證通知最終能成功。(通知頻率為15s/15s/30s/3m/10m/20m/30m/30m/30m/60m/3h/3h/3h/6h/6h - 總計(jì) 24h4m)

3.2.4. 【服務(wù)端】查詢訂單
步驟說明：當(dāng)商戶后臺、網(wǎng)絡(luò)、服務(wù)器等出現(xiàn)異常，商戶系統(tǒng)最終未接收到支付通知時商戶可通過查詢訂單接口核實(shí)訂單支付狀態(tài)
示例代碼(通過微信訂單號查詢)：
public void QueryOrder() throws Exception {
//請求URL
HttpGet httpGet = new HttpGet("https://api.mch.weixin.qq.com/v3/pay/partner/transactions/id/1217752501201407033233368018?sp_mchid=1230000109&sub_mchid=1900000109");

//完成簽名并執(zhí)行請求
CloseableHttpResponse response = httpClient.execute(httpGet);

注意：
查詢訂單可通過微信支付訂單號或商戶訂單號兩種方式查詢，兩種查詢方式返回結(jié)果相同

3.2.5. 【服務(wù)端】關(guān)閉訂單
步驟說明：當(dāng)商戶訂單支付失敗需要生成新單號重新發(fā)起支付，要對原訂單號調(diào)用關(guān)單，避免重復(fù)支付；系統(tǒng)下單后，用戶支付超時，系統(tǒng)退出不再受理，避免用戶繼續(xù)，請調(diào)用關(guān)單接口
示例代碼：

步驟說明：通過申請交易賬單接口獲取到賬單下載地址(download_url)后，再通過該接口獲取到對應(yīng)的賬單文件，文件內(nèi)包含交易相關(guān)的金額、時間、營銷等信息，供商戶核對訂單、退款、銀行到賬等情況
示例代碼：
public void DownloadUrl(String download_url) throws Exception{
PrivateKey merchantPrivateKey = PemUtil.loadPrivateKey(new ByteArrayInputStream(privateKey.getBytes("utf-8")));
//初始化httpClient
//該接口無需進(jìn)行簽名驗(yàn)證、通過withValidator((response) -> true)實(shí)現(xiàn)
httpClient = WechatPayHttpClientBuilder.create().withMerchant(mchId, mchSerialNo, merchantPrivateKey).withValidator((response) -> true).build();
//請求URL
//賬單文件的下載地址的有效時間為30s
URIBuilder uriBuilder = new URIBuilder(download_url);
HttpGet httpGet = new HttpGet(uriBuilder.build());
httpGet.addHeader("Accept", "application/json");
//執(zhí)行請求
CloseableHttpResponse response = httpClient.execute(httpGet);
try {
int 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");
} else {
System.out.println("failed,resp code = " + statusCode+ ",return body = " + EntityUtils.toString(response.getEntity()));
throw new IOException("request failed");
}
} finally {
response.close();
}
}
try {
$resp = $client->request(
'GET',
'https://api.mch.weixin.qq.com/v3/billdownload/file?token=xx', //請求URL
[
'headers' => [ 'Accept' => 'application/json']
]
);
$statusCode = $resp->getStatusCode();
if ($statusCode == 200) { //處理成功
echo "success,return body = " . $resp->getReasonPhrase()."\n";
} else if ($statusCode == 204) { //處理成功，無返回Body
echo "success";
}
} catch (RequestException $e) {
// 進(jìn)行錯誤處理
echo $e->getMessage()."\n";
if ($e->hasResponse()) {
echo "failed,resp code = " . $e->getResponse()->getStatusCode() . " return body = " . $e->getResponse()->getBody() . "\n";
}
return;
}
func CreateOrder() {
// 初始化客戶端
ctx := context.TODO()
opts, err := SetUp()
if err != nil {
return
}
client, err := core.NewClient(ctx, opts...,)
if err != nil{
log.Printf("init client err:%s",err)
return
}
//設(shè)置請求地址
URL := "https://api.mch.weixin.qq.com/v3/billdownload/file?token=xxx" //申請賬單接口獲取到的download_url
// 發(fā)起請求
response, err := client.Get(ctx, URL)
if err != nil{
log.Printf("client get err:%s",err)
return
}
// 校驗(yàn)回包內(nèi)容是否有邏輯錯誤
err = core.CheckResponse(response)
if err != nil{
log.Printf("check response err:%s",err)
return
}
// 讀取回包信息
body, err := ioutil.ReadAll(response.Body)
if err != nil{
log.Printf("read response body err:%s",err)
return
}
fmt.Println(string(body))
}
注意：
? 賬單文件的下載地址的有效時間為30s
? 強(qiáng)烈建議商戶將實(shí)際賬單文件的哈希值和之前從接口獲取到的哈希值進(jìn)行比對，以確認(rèn)數(shù)據(jù)的完整性
