微信支付

先介绍一下步骤

1 配置平台信息，这是基本条件，具体就不讲了。

2.微信支付必须跟后台相配合，本地生成订单－>提交订单信息.->返回参数（订单ID 、支付ID＊＊＊等一系列参数）

3.设置支付参数、本地MD5签名

4.调起微信支付

-(void)pay

{

// 拿到返回的订单参数后。indentData 则为提交订单后返回的参数

[ self chuanzhidata:indentData];

//调起微信支付也是最后一步

NSMutableString *stamp = [dict objectForKey:@"timestamp"];

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"];

[WXApisendReq:req];

}

// 第一步

-(NSMutableDictionary *)chuanzhidata:(NSDictionary *)dicdata

{

//dicdata 向服务器提交支付订单的返回值。

//设置支付参数

NSString *time_stamp;

time_t now;

time(&now);

time_stamp = [NSString stringWithFormat:@"%ld", now];

NSString *appid = [NSStringstringWithFormat:@"%@",[[dicdataobjectForKey:@"weixin"]objectForKey:@"appid"]];

NSString *nonce_str = [[dicdata objectForKey:@"weixin"] objectForKey:@"nonce_str"];

NSString *package = @"Sign=WXPay";

NSString *mchid = [NSString stringWithFormat:@"%@",[[dicdata objectForKey:@"weixin"] objectForKey:@"mch_id"]];

time_stamp = time_stamp;

NSString *prePayid = [NSString stringWithFormat:@"%@",[[dicdata objectForKey:@"weixin"] objectForKey:@"prepay_id"]];

NSMutableDictionary *signParams = [NSMutableDictionary dictionary];

[signParams setObject: appid forKey:@"appid"];

[signParams setObject: nonce_str forKey:@"noncestr"];

[signParams setObject: package forKey:@"package"];

[signParams setObject: mchid forKey:@"partnerid"];

[signParams setObject: time_stamp forKey:@"timestamp"];

[signParams setObject: prePayid forKey:@"prepayid"];

// [signParams setObject: @"MD5" forKey:@"signType"];

//生成签名，调用下一个方法

NSString *sign = [self createMd5Sign:signParams];

[signParams setObject: sign forKey:@"sign"];

return signParams;

}

／／第二步

-(NSString*) createMd5Sign:(NSMutableDictionary*)dict //生成签名的方法

{

NSMutableString *contentString =[NSMutableString string];

NSArray *keys = [dict allKeys];

//按字母顺序排序

NSArray *sortedArray = [keys sortedArrayUsingComparator:^NSComparisonResult(id obj1, id obj2) {

return [obj1 compare:obj2 options:NSNumericSearch];

}];

//拼接字符串

for (NSString *categoryId in sortedArray) {

if ( ![[dict objectForKey:categoryId] isEqualToString:@""]

&& ![categoryId isEqualToString:@"sign"]

&& ![categoryId isEqualToString:@"key"]

)

{

[contentString appendFormat:@"%@=%@&", categoryId, [dict objectForKey:categoryId]];

}

//添加key字段

[contentString appendFormat:@"key=%@", @"＊＊＊＊＊＊＊＊＊＊＊＊＊"]; //秘钥，可找后台拿到

//得到MD5 sign签名

NSString *md5Sign =[WXUtil md5:contentString];

//输出Debug Info

// [debugInfo appendFormat:@"MD5签名字符串：\n%@\n\n",contentString];

return md5Sign;

}

支付结果

appdelegate.m

-(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！";

break;

default:

strMsg = [NSString stringWithFormat:@"支付结果：失败"];

break;

}

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];

[alert show];

}
