一.微信支付流程
1.导入SDK
44.png
2.导入相关的系统库及文件。不导入会报错。
SystemConfiguration.framework
libz.tbd
libsqlite3.0.tbd
CoreTelephony.framework
libc++.tbd
3.配置info.plist
a.schemes ，注意，item0 这里要修改成商户自己的APPID
45.png
b.白名单
46.png
4.修改bitcode

5.在AppDelegate 注册微信
导入#import "WXApiManager.h"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//向微信注册wxd930ea5d5a258f4f
[WXApi registerApp:@"wxb4ba3c02aa476ea1" withDescription:@"demo 2.0"];
return YES;
}
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
return [WXApi handleOpenURL:url delegate:[WXApiManager sharedManager]];
}
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
return [WXApi handleOpenURL:url delegate:[WXApiManager sharedManager]];
}
6.接下来，就是发起请求支付了，实现上核心代码只有几行
//调起微信支付
PayReq* req = [[[PayReq alloc] init]autorelease];
req.partnerId = [dict objectForKey:@"partnerid"];
req.prepayId = [dict objectForKey:@"prepayid"];
req.nonceStr = [dict objectForKey:@"noncestr"];
req.timeStamp = stamp.intValue;
req.package = [dict objectForKey:@"package"];
req.sign = [dict objectForKey:@"sign"];
[WXApi sendReq:req];
7.不管支付成功还是失败,我们直接处理回调结果即可
switch (resp.errCode) {
case WXSuccess:
strMsg = @"支付结果：成功！";
NSLog(@"支付成功－PaySuccess，retcode = %d", resp.errCode);
break;
default:
strMsg = [NSString stringWithFormat:@"支付结果：失败！retcode = %d, retstr = %@", resp.errCode,resp.errStr];
NSLog(@"错误，retcode = %d, retstr = %@", resp.errCode,resp.errStr);
break;
}
客户端进行签名
1.导入文件。
49.png
![Uploading 48_198784.png . . .]
2.里面有两个文件是非arc的，我们需要设置一下 -fno-objc-arc
48.png
3.导入系统库及info.list配置，请参数上面服务端签名。
4.AppDelegate配置
1）导入头文件
#import "WXApi.h"
#import "payRequsestHandler.h"
2）实现微信代理
@interface AppDelegate ()
@end
3）注册微信，及微信支付回调
复制代码
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
//向微信注册
[WXApi registerApp:APP_ID withDescription:@"demo 2.0"];
return YES;
}
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url
{
return [WXApi handleOpenURL:url delegate:self];
}
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
return [WXApi handleOpenURL:url delegate:self];
}
// 微信支付成功或者失败回调
-(void) onResp:(BaseResp*)resp
{
NSString *strMsg = [NSString stringWithFormat:@"errcode:%d", resp.errCode];
NSString *strTitle;
if([resp isKindOfClass:[SendMessageToWXResp class]])
{
strTitle = [NSString stringWithFormat:@"发送媒体消息结果"];
}
if([resp isKindOfClass:[PayResp class]]){
//支付返回结果，实际支付结果需要去微信服务器端查询
strTitle = [NSString stringWithFormat:@"支付结果"];
switch (resp.errCode) {
case WXSuccess:
strMsg = @"支付结果：成功！";
NSLog(@"支付成功－PaySuccess，retcode = %d", resp.errCode);
break;
default:
strMsg = [NSString stringWithFormat:@"支付结果：失败！retcode = %d, retstr = %@", resp.errCode,resp.errStr];
NSLog(@"错误，retcode = %d, retstr = %@", resp.errCode,resp.errStr);
break;
}
}
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
[alert show];
}
5.写方法直接在支付时调用
复制代码
- (void)payForWechat
{
//创建支付签名对象
payRequsestHandler *req = [[payRequsestHandler alloc] init];
//初始化支付签名对象
[req init:APP_ID mch_id:MCH_ID];
//设置密钥
[req setKey:PARTNER_ID];
NSMutableDictionary *dict = [req sendPay_demo];
if(dict != nil){
NSMutableString *retcode = [dict objectForKey:@"retcode"];
if (retcode.intValue == 0){
NSMutableString *stamp = [dict objectForKey:@"timestamp"];
//调起微信支付
PayReq* req = [[PayReq alloc] init];
req.openID = [dict objectForKey:@"appid"];
req.partnerId = [dict objectForKey:@"partnerid"];
req.prepayId = [dict objectForKey:@"prepayid"];
req.nonceStr = [dict objectForKey:@"noncestr"];
req.timeStamp = stamp.intValue;
req.package = [dict objectForKey:@"package"];
req.sign = [dict objectForKey:@"sign"];
[WXApi sendReq:req];
//日志输出
NSLog(@"appid=%@\npartid=%@\nprepayid=%@\nnoncestr=%@\ntimestamp=%ld\npackage=%@\nsign=%@",req.openID,req.partnerId,req.prepayId,req.nonceStr,(long)req.timeStamp,req.package,req.sign );
}else{
[self alert:@"提示信息" msg:[dict objectForKey:@"retmsg"]];
}
}else{
[self alert:@"提示信息" msg:@"服务器返回错误，未获取到json对象"];
}
}
//客户端提示信息
- (void)alert:(NSString *)title msg:(NSString *)msg
{
UIAlertView *alter = [[UIAlertView alloc] initWithTitle:title message:msg delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alter show];
}
二.支付宝支付流程
步骤1: 启动IDE(如Xcode),把iOS包中的压缩文件中以下文件拷贝到项目文件夹下,并导入到项目工程中。
AlipaySDK.bundle
AlipaySDK.framework
步骤2: 在需要调用AlipaySDK的文件中,增加头文件引用。
#import
步骤3: 配置请求信息。
Order *order = [[Order alloc] init];
order.partner = partner;//合作身份者ID,以 2088 开头由 16 位纯数字组成的字符串。请参考“7.1 如何获得PID与 密钥”。
order.seller = seller;//支付宝收款账号,手机号码或邮箱格式。
private_key//商户方的私钥,pkcs8 格式
order.tradeNO = [self generateTradeNO]; //订单ID(由商家□自□行制定)
order.productName = product.subject; //商品标题 order.productDescription = product.body; //商品描述
order.amount = [NSString stringWithFormat:@"%.2f",product.price]; //商 品价格
order.notifyURL = @"http://www.xxx.com"; //回调URL order.service = @"mobile.securitypay.pay"; order.paymentType = @"1";
order.inputCharset = @"utf-8";
order.itBPay = @"30m";
//应用注册scheme,在AlixPayDemo-Info.plist定义URL types NSString *appScheme = @"alisdkdemo";
//将商品信息拼接成字符串
NSString *orderSpec = [order description]; NSLog(@"orderSpec = %@",orderSpec);
//获取私钥并将商户信息签名,外部商户可以根据情况存放私钥和签名,只需要遵循 RSA 签名规范,并将签名字符串 base64 编码和 UrlEncode
id signer = CreateRSADataSigner(privateKey);
NSString *signedString = [signer signString:orderSpec];
//将签名成功字符串格式化为订单字符串,请严格按照该格式NSString *orderString = nil;
if (signedString != nil) {
orderString = [NSString stringWithFormat:@"%@&sign=\"%@\"&sign_type=\"%@\"",
orderSpec, signedString, @"RSA"];
[[AlipaySDK defaultService] payOrder:orderString fromScheme:appScheme callback:^(NSDictionary *resultDic) {
NSLog(@"reslut = %@",resultDic);
}];
步骤4: 配置支付宝客户端返回url处理方法.
如示例 AliSDKDemo\APAppDelegate.m 文件中,@implementation AppDelegate 中增加如下代码:
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
//如果极简 SDK 不可用,会跳转支付宝钱包进行支付,需要将支付宝钱包的支付结果回传给 SDK
if ([url.host isEqualToString:@"safepay"]) {
[[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
NSLog(@"result = %@",resultDic);
}];
}
if ([url.host isEqualToString:@"platformapi"]){//支付宝钱包快登授权返回authCode
[[AlipaySDK defaultService] processAuthResult:url standbyCallback:^(NSDictionary *resultDic) {
NSLog(@"result = %@",resultDic);
}];
}
return YES; }
三.md5
1、 导入头文件：
#import
2、加密的方法：
- (NSString *) md5:(NSString *) input {
const charchar *cStr = [input UTF8String];
unsigned char digest[CC_MD5_DIGEST_LENGTH];
CC_MD5( cStr, strlen(cStr), digest ); // This is the md5 call
NSMutableString *output = [NSMutableString stringWithCapacity:CC_MD5_DIGEST_LENGTH * 2];
for(int i = 0; i < CC_MD5_DIGEST_LENGTH; i++)
[output appendFormat:@"%02x", digest[i]];
return output;
}
3、调用加密方法：
NSString *str = @"123456";
NSString *result = [self md5:str];
NSLog(@"%@",result);
四.sha1
//sha1加密方式
- (NSString *)getSha1String:(NSString *)srcString{
constchar *cstr = [srcString cStringUsingEncoding:NSUTF8StringEncoding];
NSData *data = [NSDatadataWithBytes:cstr length:srcString.length];
uint8_t digest[CC_SHA1_DIGEST_LENGTH];
CC_SHA1(data.bytes, data.length, digest);
NSMutableString* result = [NSMutableStringstringWithCapacity:CC_SHA1_DIGEST_LENGTH * 2];
for(int i = 0; i < CC_SHA1_DIGEST_LENGTH; i++) {
[result appendFormat:@"%02x", digest[i]];
}
return result;
}
[resultLabel1setText:[selfgetSha1String:srcStringTextField.text]];
