1、設(shè)置URL Schemes
2、在AppDelegate里注冊(cè)微信支付[WXApi registerApp:@"appid"];
3、調(diào)起微信支付
PayReq *request = [[[PayReq alloc] init] autorelease];
request.partnerId = @"10000100";
request.prepayId= @"1101000000140415649af9fc314aa427";
request.package = @"Sign=WXPay";
request.nonceStr= @"a462b76e7436e98e0ed6e13c64b4fd1c";
request.timeStamp= @"1397527777";
request.sign= @"582282D72DD2B03AD892830965F428CB16E7A256";
[WXApi sendReq:request];
在調(diào)起微信支付之前需要向服務(wù)器獲取微信支付的相關(guān)參數(shù)，這些參數(shù)是服務(wù)器調(diào)用微信的統(tǒng)一下單API所得，問(wèn)題出在服務(wù)器生成的簽名錯(cuò)誤，根據(jù)微信官方給出的iOS demo，整理下流程，供服務(wù)器校對(duì)：
1、預(yù)付單參數(shù)設(shè)置
Printing description of packageParams:
{
appid = wxbfe7bd3faa6e56d6;
body = "V3\U652f\U4ed8\U6d4b\U8bd5";
"device_info" = "APP-001";
"mch_id" = 1245634502;
"nonce_str" = 1024782077;
"notify_url" = "http://wxpay.weixin.qq.com/pub_v2/pay/notify.v2.php";
"out_trade_no" = 1436870256;
"spbill_create_ip" = "192.168.1.127";
"total_fee" = 1;
"trade_type" = APP;
}
2、生成prePayid
（1）獲取package帶參數(shù)的簽名包
a、生成簽名
參數(shù)
Printing description of dict:
{
appid = appid;
body = "V3\U652f\U4ed8\U6d4b\U8bd5";
"device_info" = "APP-001";
"mch_id" = 1245634502;
"nonce_str" = 1024782077;
"notify_url" = "http://wxpay.weixin.qq.com/pub_v2/pay/notify.v2.php";
"out_trade_no" = 1436870256;
"spbill_create_ip" = "192.168.1.127";
"total_fee" = 1;
"trade_type" = APP;
}
b、生成xml的package
結(jié)果
< xml>
< mch_id>1245634502
< out_trade_no>1436870256
< device_info>APP-001
< nonce_str>1024782077
< total_fee>1
< notify_url>http://wxpay.weixin.qq.com/pub_v2/pay/notify.v2.php
< spbill_create_ip>192.168.1.127
< body>V3支付測(cè)試
< appid>appid
< trade_type>APP
< sign>B220AF98FC3638EC1A5AD5C3808BB0F8
< /xml>
c、post向微信發(fā)起請(qǐng)求，參數(shù)為上邊的xml
返回值：
< xml>
