ios微信支付开发遇到的问题

Question

最近在做ios端微信支付的时候遇到无法挂起微信界面的情况，执行[WXApi safeSendReq:req] 后 ，只看到微信的启动图，然后一闪而过又回到之前app，检查过了不是签名的问题，参数都是通过服务端传递，android版本是可以支付的，请问有人知道吗

Answer 1

我也遇到了这个问题，没看出来原因，请楼主帮我看下呢：
PayReq *request = [[PayReq alloc] init];
        request.openID=@"wxd930ea5d5a258f4f";
        request.partnerId = @"1900000109";//[resultDic objectForKey:@"partnerid"];
        request.prepayId= @"1101000000140429eb40476f8896f4c9";//[resultDic objectForKey:@"partnerid"];
        request.package = @"Sign=WXpay";
        request.nonceStr= @"139042a4157a773f209847829d80894d";//[resultDic objectForKey:@"noncestr"];
        NSString *timeStamp = [NSString stringWithFormat:@"%@", @"1398746574"];
        request.timeStamp = [timeStamp intValue];
        request.sign= @"7ffecb600d7157c5aa49810d2d8f28bc2811827b";//[resultDic objectForKey:@"sign"];
        [WXApi safeSendReq:request];

Answer 2

  你这里的openid  是不需要传得   难道之前没有进行appid的注册？

Answer 3

1.检查签名是否正确
2.在URL Schemes中检查是否添加微信 appid
3.是否注册appid这三个是比较常见的无法启动微信支付的问题

Answer 4

PayReq *request = [[PayReq alloc] init];
        request.openID=@"wxd930ea5d5a258f4f";
        request.partnerId = @"1900000109";//[resultDic objectForKey:@"partnerid"];
        request.prepayId= @"1101000000140429eb40476f8896f4c9";//[resultDic objectForKey:@"partnerid"];
        request.package = @"Sign=WXpay";
        request.nonceStr= @"139042a4157a773f209847829d80894d";//[resultDic objectForKey:@"noncestr"];
        NSString *timeStamp = [NSString stringWithFormat:@"%@", @"1398746574"];
        request.timeStamp = [timeStamp intValue];
        request.sign= @"7ffecb600d7157c5aa49810d2d8f28bc2811827b";//[resultDic objectForKey:@"sign"];
//        [WXApi safeSendReq:request];
        [WXApi sendReq:request];

Answer 5

PayReq *request = [[PayReq alloc] init];
        request.openID=@"wxd930ea5d5a258f4f";
        request.partnerId = @"1900000109";//[resultDic objectForKey:@"partnerid"];
        request.prepayId= @"1101000000140429eb40476f8896f4c9";//[resultDic objectForKey:@"partnerid"];
        request.package = @"Sign=WXpay";
        request.nonceStr= @"139042a4157a773f209847829d80894d";//[resultDic objectForKey:@"noncestr"];
        NSString *timeStamp = [NSString stringWithFormat:@"%@", @"1398746574"];
        request.timeStamp = [timeStamp intValue];
        request.sign= @"7ffecb600d7157c5aa49810d2d8f28bc2811827b";//[resultDic objectForKey:@"sign"];
//        [WXApi safeSendReq:request];
        [WXApi sendReq:request];

Answer 6

        PayReq *request = [[PayReq alloc] init];
        request.partnerId =[responseObject objectForKey:@"partnerId"];
        request.prepayId = [responseObject objectForKey:@"prepayId"];
        request.nonceStr = [responseObject objectForKey:@"nonceStr"];
        request.timeStamp = [[responseObject objectForKey:@"timeStamp"] intValue];
        request.package = @"Sign=WXpay";
        request.sign = [responseObject objectForKey:@"sign"];
  
        [WXApi sendReq:request];
//        [WXApi safeSendReq:request];
我的微信支付 用了下面那句调用 就会跳到微信再回来 但是没有支付页面    用上面的那个句请求 连微信都不打开 求解

Answer 7

 PayReq *request = [[PayReq alloc] init];
        request.partnerId =[responseObject objectForKey:@"partnerId"];
        request.prepayId = [responseObject objectForKey:@"prepayId"];
        request.nonceStr = [responseObject objectForKey:@"nonceStr"];
        request.timeStamp = [[responseObject objectForKey:@"timeStamp"] intValue];
        request.package = @"Sign=WXpay";
        request.sign = [responseObject objectForKey:@"sign"];
      [WXApi safeSendReq:request];
写法上都没错，我写这个微信支付遇到的问题就是跳到微信马上跳回app，当时上面几个参数都是后台返回的，request.package这个参数应该是Sign= WXpay,但是我们后台返回来是Sign\u003dWXpay,发现问题后，让后台改了下，再运行，问题解决了

Answer 8

我的问题也解决了，根据微信提供的demo多次对比后台的签名发现问题，后台在第二次签名时没有用 @"Sign=WXpay"，虽然文档中说这样写request.package = @"prepay_id=1101000000140415649af9fc314aa427";但是不能这样，无论是第二次签名还是传给客户端都要用 @"Sign=WXpay"

Answer 9

应该是签名问题，你用demo的签名算法自己算出签名再试试

Answer 10

ios上不会来，安卓上正常，为什么？

把库导入后出现这种情况，该导入的文件也导入了，就是编译不过，请楼主指教

Answer 12

是不是没有设置编译方式，微信是c++与oc混编的

Answer 13

签名的问题  用微信支付的demo的签名算法重新生成签名就可

Answer 14

xcode升级7之后，微信支付使用不了了，怎么办

Answer 15

我的微信支付也是输入支付密码之后出现无法解析 ,原因为：我在调取微信时，Android与IOS获取服务端prepay_id=wx20151009111454e0b583ff87025232107810时，Android是可以调取，但iOS出现解析问题。后台改为package         = @"Sign=WXPay"; 可以成功支付。

Answer 16

请问ios跳不出支付的原因就是package         = @"Sign=WXPay";  这个吗？

Answer 17

{"appId":"wx9e5b5b3a78f12349b34","nonceStr":"3add177074b0409a88d5cc5980545f33","package":"prepay_id=wx201510191738d3443d1df2012880127352","paySign":"76AB75480D100C9696CF86D7C7FACAC62","signType":"MD5","timeStamp":"1445246139"}
这个哪有错？在IOS调用不出支付窗口

Answer 18

请问一下IOS调用不成功是神原因？

Answer 19

安卓的可以正常的进行微信支付，为什么iOS 不能正常的进行支付 ，请问楼主怎么解决

Answer 20

Sign=WXPay别有空格
