10分鐘搞定支付寶和微信支付 的 各種填坑

填坑
支付寶填坑是每個接入支付寶必經(jīng)之路，下面是我接入支付寶遇到的問題匯總，希望大家在接入的路上少一點彎路

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

解決辦法：
這是base64.h中沒有加入#import <Foundation/Foundation.h> 系統(tǒng)庫文件導致，這個錯誤報錯方法直接想噴它一臉。報錯方式太惡心。

問題2.截圖告知你什么問題


530EA189-0A5A-4AEB-82BF-E30B99F5418B.png
解決辦法：
這個問題可以同上的，心情好，截圖再次說明下，在 openssl_wrapper.h中#import <Foundation/Foundation.h> 庫即可

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

解決辦法：
（1），萬年老坑，只要你接入支付寶百分百要遇到的問題，所以習以為常吧
（2），在Build setting中搜索search，找到Header Search Paths，添加$(PROJECT_DIR)/openssl和$(PROJECT_DIR) 如下圖：
（3），重要 問題說三遍，這是網(wǎng)絡找到的到答案后繼續(xù)有同樣的坑，自己的解決方案,
Header Search Paths   $(PROJECT_DIR)/ali中輸入這個
Framework Search Paths  和 Library Search Paths 繼續(xù)是$(inherited)  和  $(PROJECT_DIR)/ali
‘rsa.h’ file not found  的解決方案
（4），由于后期多項目的接入，讓我知道一個算是萬能方法吧，就是始終保持Header Search Paths 和 Library Search Paths 都能找到你導入的openssl的正確路徑即可，已嘗試多遍，是能解決以上問題（求黑）

問題4.這類錯很多，大概有這些：這些可能是庫文件沒有導入，導致的

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

解決辦法：
這種問題通過在General->Link Framework and Libraiies中添加以下framework解決：

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

截圖如下，由于公司同時接入支付寶和微信支付，所以導入的庫就多了點咯：

問題5.Redefinition of 'RSA' as different kind of symbol 多為sdk集成時產(chǎn)生的坑，因為我們公司在集成支付寶之前，有用過RSA加密，導致重名問題

解決辦法：
（1），這個問題不是每個公司都可能遇到的，但遇到也心煩
（2），由于支付寶中的openssl中的rsa.h文件與RSA加密有重名沖突。改掉公司自己之前導入RSA的命名，如果你牛逼也可以去改rsa.h中的

問題6；系統(tǒng)庫導入問題
+++++++++++++
symbol(s) not found for architecture arm64


17321E6C-1A33-41D4-9B6E-9E499CCA23C6.png

解決辦法
就是導入系統(tǒng)庫了

問題7：終于到微信了，接入微信，你就開心了
因為問題太少了，只能感謝下這兩個帖子的樓主了
解決辦法：
使用微信支付SDK1.5版本的支付demo
微信支付如果遇到跳轉只有一個確定請看這里

為了一些懶人懶的去看帖子，簡單說，就是微信支付注冊放在友盟分享之后就ok了！
代碼示例：

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

問題8：
拉起微信支付后，在微信支付注冊在友盟之后仍然跳轉到微信還是一個確定按鈕，點擊確定按鈕回到自己的應用
解決辦法：
這個是后端返回的參數(shù)有問題，一般是sign簽名有問題，
************注意：
1.簽名 后端簽名是要用到下面6個參數(shù)進行簽名，appId，partnerId，noncestr，timestamp，package prepaid，簽名過程中，6個參數(shù)都是小寫，簽名后字符轉為大寫，sign字符全是大寫
2.隨機串 請求預交易訂單返回的
3.時間戳 訂單結束時間

舉例：如下是請求后端返回的數(shù)據(jù)

  ["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和自己簽名的sign做個比較，native已經(jīng)認證過，沒有錯誤

-(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];
    //簽名的6個鍵值對中的key都必須小寫
    [signParams setObject:appid_key forKey:@"appid"];//微信appid 例如wxfb132134e5342
    [signParams setObject:noncestr_key forKey:@"noncestr"];//隨機字符串
    [signParams setObject:package_key forKey:@"package"];//擴展字段  參數(shù)為 Sign=WXPay
    [signParams setObject:partnerid_key forKey:@"partnerid"];//商戶賬號
    [signParams setObject:prepayid_key forKey:@"prepayid"];//此處為統(tǒng)一下單接口返回的預支付訂單號
    [signParams setObject:[NSString stringWithFormat:@"%u",timestamp_key] forKey:@"timestamp"];//時間戳
   
    
    NSMutableString *contentString  =[NSMutableString string];
    NSArray *keys = [signParams allKeys];
    //按字母順序排序
    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]];
        }
    }
    //添加商戶密鑰key字段  API 密鑰   這里的key需要換成自己公司商戶密鑰
    [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<CC_MD5_DIGEST_LENGTH;i++)
    {
        [ms appendFormat: @"%02x", (int)(digest[i])];
    }
    
    [ms uppercaseString];
    //轉為大寫
    NSString *big = [ms uppercaseString];
    NSLog(@"sign %@",big);
    return [big copy];
}

這里NSLog后的值為
2016-05-30 17:41:01.166 FPHClient[15313:6309040] sign 322B952AC0678F21DD1F7C5B1F444886
和后端返回的一樣

4.partnerId

問題9：
拉起支付寶報錯：
交易訂單處理失敗,請稍后再試(ALI64)

解決辦法：
重新生成私鑰和公鑰，執(zhí)行步驟如下個問題

問題8：
支付寶要重新生成私鑰和公鑰，并上傳修改公鑰 -- 為你補充

解決辦法：
RSA密鑰生成命令步驟如下：

(1)先在終端鍵入 openssl
生成RSA私鑰
(2)openssl>genrsa -out rsa_private_key.pem 1024
生成RSA公鑰
(3)openssl>rsa -in rsa_private_key.pem -pubout -out rsa_public_key.pem
將RSA私鑰轉換成PKCS8格式
(4)openssl>pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt
注意：“>”符號后面的才是需要輸入的命令。

生成的文件：
這里寫圖片描述

屏幕快照 2016-05-11 10.38.17.png

把公鑰上傳到支付寶，然后把pkcs8 -topk8 -inform PEM -in rsa_private_key.pem -outform PEM -nocrypt 這條命令產(chǎn)生的私鑰用在下面設置中就好
然后設置

/*
     *商戶的唯一的parnter和seller。
     *簽約后，支付寶會為每個商戶分配一個唯一的 parnter 和 seller。
     */
    
    /*============================================================================*/
    /*=======================需要填寫商戶app申請的===================================*/
    /*============================================================================*/
    NSString *partner = PartnerID;//合作伙伴身份（PID）:
    NSString *seller = SellerID;//商戶支付寶賬戶
    //獲取私鑰并將商戶信息簽名,外部商戶可以根據(jù)情況存放私鑰和簽名,只需要遵循RSA簽名規(guī)范,并將簽名字符串base64編碼和UrlEncode
    NSString *privateKey = PartnerPrivKey;// 剛第三端命令生成的去頭去尾

如有問題，繼續(xù)分享咯，總結才能讓問題越來越少！
