10分钟搞定支付宝和微信支付 的 各种填坑

填坑
支付宝填坑是每个接入支付宝必经之路，下面是我接入支付宝遇到的问题汇总，希望大家在接入的路上少一点弯路

问题1. Util/base64.h:63:21: Cannot find interface declaration for ‘NSObject’, superclass of ‘Base64’

解决办法：
这是base64.h中没有加入#import  系统库文件导致，这个错误报错方法直接想喷它一脸。报错方式太恶心。

问题2.截图告知你什么问题

530EA189-0A5A-4AEB-82BF-E30B99F5418B.png

解决办法：
这个问题可以同上的，心情好，截图再次说明下，在 openssl_wrapper.h中#import  库即可

问题3.Util/openssl_wrapper.m:11:9: ‘rsa.h’ file not found

解决办法：
（1），万年老坑，只要你接入支付宝百分百要遇到的问题，所以习以为常吧
（2），在Build setting中搜索search，找到Header Search Paths，添加$(PROJECT_DIR)/openssl和$(PROJECT_DIR) 如下图：
（3），重要 问题说三遍，这是网络找到的到答案后继续有同样的坑，自己的解决方案,
Header Search Paths   $(PROJECT_DIR)/ali中输入这个
Framework Search Paths  和 Library Search Paths 继续是$(inherited)  和  $(PROJECT_DIR)/ali
‘rsa.h’ file not found  的解决方案
（4），由于后期多项目的接入，让我知道一个算是万能方法吧，就是始终保持Header Search Paths 和 Library Search Paths 都能找到你导入的openssl的正确路径即可，已尝试多遍，是能解决以上问题（求黑）

问题4.这类错很多，大概有这些：这些可能是库文件没有导入，导致的

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

解决办法：
这种问题通过在General->Link Framework and Libraiies中添加以下framework解决：

- libz.tbd
- libc++.tbd
- Security.framework
- CoreMotion.Framework
- CFNetwork.framework
- CoreTelephony.framework
- SystemConfiguration.framework

截图如下，由于公司同时接入支付宝和微信支付，所以导入的库就多了点咯：

问题5.Redefinition of 'RSA' as different kind of symbol 多为sdk集成时产生的坑，因为我们公司在集成支付宝之前，有用过RSA加密，导致重名问题

解决办法：
（1），这个问题不是每个公司都可能遇到的，但遇到也心烦
（2），由于支付宝中的openssl中的rsa.h文件与RSA加密有重名冲突。改掉公司自己之前导入RSA的命名，如果你牛逼也可以去改rsa.h中的

问题6；系统库导入问题
+++++++++++++
symbol(s) not found for architecture arm64

解决办法
就是导入系统库了

问题7：终于到微信了，接入微信，你就开心了
因为问题太少了，只能感谢下这两个帖子的楼主了
解决办法：
使用微信支付SDK1.5版本的支付demo
微信支付如果遇到跳转只有一个确定请看这里

为了一些懒人懒的去看帖子，简单说，就是微信支付注册放在友盟分享之后就ok了！
代码示例：

// 友盟分享
    [self configUmengShare];
//向微信注册
    [WXApi registerApp:@"wxb4ba3c02aa476ea1" withDescription:@"demo 2.0"];

问题8：
拉起微信支付后，在微信支付注册在友盟之后仍然跳转到微信还是一个确定按钮，点击确定按钮回到自己的应用
解决办法：
这个是后端返回的参数有问题，一般是sign签名有问题，
************注意：
1.签名 后端签名是要用到下面6个参数进行签名，appId，partnerId，noncestr，timestamp，package prepaid，签名过程中，6个参数都是小写，签名后字符转为大写，sign字符全是大写
2.随机串 请求预交易订单返回的
3.时间戳 订单结束时间

举例：如下是请求后端返回的数据

  ["appid"]=>
  string(18) "wx5e71abd366954a75"
  ["noncestr"]=>
  string(16) "Ws5NaX2MqdGejNvW"
  ["package"]=>
  string(10) "Sign=WXPay"
  ["partnerid"]=>
  string(10) "1341184101"
  ["prepayid"]=>
  string(36) "wx20160530173622a5292225780182728337"
  ["sign"]=>
  string(32) "322B952AC0678F21DD1F7C5B1F444886"
  ["timestamp"]=>
  int(1464601340)
}

把后端返回的sign和自己签名的sign做个比较，native已经认证过，没有错误

-(NSString *)createMD5SingForPayWithAppID:(NSString *)appid_key partnerid:(NSString *)partnerid_key prepayid:(NSString *)prepayid_key package:(NSString *)package_key noncestr:(NSString *)noncestr_key timestamp:(UInt32)timestamp_key{
    NSMutableDictionary *signParams = [NSMutableDictionary dictionary];
    //签名的6个键值对中的key都必须小写
    [signParams setObject:appid_key forKey:@"appid"];//微信appid 例如wxfb132134e5342
    [signParams setObject:noncestr_key forKey:@"noncestr"];//随机字符串
    [signParams setObject:package_key forKey:@"package"];//扩展字段  参数为 Sign=WXPay
    [signParams setObject:partnerid_key forKey:@"partnerid"];//商户账号
    [signParams setObject:prepayid_key forKey:@"prepayid"];//此处为统一下单接口返回的预支付订单号
    [signParams setObject:[NSString stringWithFormat:@"%u",timestamp_key] forKey:@"timestamp"];//时间戳
   
    
    NSMutableString *contentString  =[NSMutableString string];
    NSArray *keys = [signParams 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 (   ![[signParams objectForKey:categoryId] isEqualToString:@""]
            && ![[signParams objectForKey:categoryId] isEqualToString:@"sign"]
            && ![[signParams objectForKey:categoryId] isEqualToString:@"key"]
            )
        {
            [contentString appendFormat:@"%@=%@&", categoryId, [signParams objectForKey:categoryId]];
        }
    }
    //添加商户密钥key字段  API 密钥   这里的key需要换成自己公司商户密钥
    [contentString appendFormat:@"key=%@", @"9db35c68b8de2d15d1d493d16fb67875"];
    
    NSString *result = [self md5StringWithString:contentString];//md5加密
    return result;
}

/**
 *  MD5 加密
 *
 *  @return 加密后字符串
 */
- (NSString *)md5StringWithString:(NSString *)str
{
    if(str == nil || [str length] == 0) return nil;
    unsigned char digest[CC_MD5_DIGEST_LENGTH], i;
    CC_MD5([str UTF8String], (int)[str lengthOfBytesUsingEncoding:NSUTF8StringEncoding], digest);
    NSMutableString *ms = [NSMutableString string];
    for(i=0;i

这里NSLog后的值为
2016-05-30 17:41:01.166 FPHClient[15313:6309040] sign 322B952AC0678F21DD1F7C5B1F444886
和后端返回的一样

4.partnerId

问题9：
拉起支付宝报错：
交易订单处理失败,请稍后再试(ALI64)

解决办法：
重新生成私钥和公钥，执行步骤如下个问题

问题8：
支付宝要重新生成私钥和公钥，并上传修改公钥 -- 为你补充

解决办法：
RSA密钥生成命令步骤如下：

(1)先在终端键入 openssl
生成RSA私钥
(2)openssl>genrsa -out rsa_private_key.pem 1024
生成RSA公钥
(3)openssl>rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem
将RSA私钥转换成PKCS8格式
(4)openssl>pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt
注意：“>”符号后面的才是需要输入的命令。
使用

生成的文件：
这里写图片描述

屏幕快照 2016-05-11 10.38.17.png

把公钥上传到支付宝，然后把pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt 这条命令产生的私钥用在下面设置中就好
然后设置

/*
     *商户的唯一的parnter和seller。
     *签约后，支付宝会为每个商户分配一个唯一的 parnter 和 seller。
     */
    
    /*============================================================================*/
    /*=======================需要填写商户app申请的===================================*/
    /*============================================================================*/
    NSString *partner = PartnerID;//合作伙伴身份（PID）:
    NSString *seller = SellerID;//商户支付宝账户
    //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
    NSString *privateKey = PartnerPrivKey;// 刚第三端命令生成的去头去尾

如有问题，继续分享咯，总结才能让问题越来越少！
