本篇主要介紹接入App原生微信支付的具體步驟（簽名在服務(wù)端進行生成，客戶端主要就是吊起支付）
注冊相關(guān)信息
1,在微信開放平臺上申請app管理，獲取AppId,AppServece.
2,認(rèn)證開發(fā)者資質(zhì)
3,申請微信支付共能
項目中集成微信sdk
-
打開工程直接將下載的SDK拖進去
SDK包內(nèi) -
導(dǎo)入SDK所依賴的庫
在 Build Phases ->Linked Frameworks and Libraries 添加 在info,plist 中添加微信白名單和網(wǎng)絡(luò)協(xié)議設(shè)置
<key>LSApplicationQueriesSchemes</key>
<array>
<string>weixin</string>
</array>
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>

將微信支付的APPID設(shè)為URL Schemes
2F6D48CB-0CFD-4836-BCB8-8D751A9854DD.png 實現(xiàn)代碼
//1.導(dǎo)入微信支付SDK,注冊微信支付
//2.設(shè)置微信APPID為URL Schemes
//3.發(fā)起支付，調(diào)起微信支付
//4.處理支付結(jié)果
#import "WXApi.h"
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//向微信注冊
[WXApi registerApp:WXKey];
}
在微信支付按鈕方法里 首先根據(jù)訂單編號傳給后臺，后臺調(diào)用微信api接口生成預(yù)支付訂單，然后將預(yù)支付訂單信息進行第二次簽名 將相關(guān)信息傳給客戶端，客戶端調(diào)用SDK方法完成微信支付。
微信支付點擊方法如下：
//以下調(diào)用后臺的方法為我們自己封裝的方法具體可按照你們自己處理的邏輯
WxpayClientEntity*client = [[WxpayClientEntity alloc]init];
client.orderid = self.orderid;
[[NSUserDefaults standardUserDefaults]setObject:client.orderid forKey:@"orderid"];
client.ipaddress =[self getIPAddress];
[[Network new]httpRequestJosn:client WithRespoinseObj:^(id respoinseObj) {
NSLog(@"%@",respoinseObj);
[MBProgressHUD showText:respoinseObj[@"message"]];
if ([[respoinseObj objectForKey:@"status"]isEqualToString:@"2000123"]) { NSDictionary*dic = [respoinseObj objectForKey:@"results"];
WxpayEntity*model = [[WxpayEntity alloc]initWithDictinary:dic];
PayReq *request = [[PayReq alloc] init];
/** 商家向財付通申請的商家id */
request.partnerId =model.partnerid;
/** 預(yù)支付訂單 */
request.prepayId= model.prepayid;
/** 商家根據(jù)財付通文檔填寫的數(shù)據(jù)和簽名 */
request.package = @"Sign=WXPay";
/** 隨機串，防重發(fā) */
request.nonceStr= model.noncestr;
/** 時間戳，防重發(fā) */
// request.timeStamp= [model.timestamp intValue];
// 將當(dāng)前時間轉(zhuǎn)化成時間戳
NSDate *datenow = [NSDate date];
NSString *timeSp = [NSString stringWithFormat:@"%ld", (long)[datenow timeIntervalSince1970]];
UInt32 timeStamp =[timeSp intValue];
request.timeStamp= timeStamp;
// * 商家根據(jù)微信開放平臺文檔對數(shù)據(jù)做的簽名
// request.sign=[self createMD5SingForPay:WXKey
// partnerid:request.partnerId
// prepayid:request.prepayId
// package:request.package
// noncestr:request.nonceStr
// timestamp:request.timeStamp];
// request.sign = model.sign;
request.sign = model.sign;
NSLog(@"%@",model.timestamp);
[WXApi sendReq: request];
}
} failBlock:^(NSHTTPURLResponse *responseObj) {
}];
在AppDelegate 實現(xiàn)如下回調(diào)方法
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{
return [WXApi handleOpenURL:url delegate:self];
}
實現(xiàn)微信支付回調(diào)協(xié)議
- (void)onResp:(BaseResp *)resp
{
//支付返回結(jié)果，實際支付結(jié)果需要去微信服務(wù)器端查詢
NSString *strMsg ,*strTitle= [NSString stringWithFormat:@"支付結(jié)果"];
switch (resp.errCode) {
case WXSuccess:
{
strMsg = @"支付結(jié)果：成功！";
// 此處寫自己協(xié)議
//通過通知中心發(fā)送通知
NSLog(@"支付成功－PaySuccess，retcode = %d", resp.errCode);
}
break;
default:
strMsg = [NSString stringWithFormat:@"支付結(jié)果：失敗！retcode = %d, retstr = %@", resp.errCode,resp.errStr];
NSLog(@"錯誤，retcode = %d, retstr = %@", resp.errCode,resp.errStr);
break;
}
}
