填坑

支付寶填坑是每個接入支付寶必經之路，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 系統庫文件導致，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.截圖告知你什麼問題

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 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，這是網絡找到的到答案後繼續有同樣的坑，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 繼續是$(inherited) 和 $(PROJECT_DIR)/ali

‘rsa.h’ file not found的解決方案

（4）由於後期多項目的接入，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，由於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）由於支付寶中的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. 系統庫導入問題

+++++++++++++

symbol(s) not found for architecture arm64

解決辦法：

就是導入系統庫了

問題7：終於到微信了，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裡

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後就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7：拉起支付寶報錯：交易訂單處理失敗,請稍後再試(ALI64)

解決辦法：

重新生成私鑰和公鑰，執行步驟如下個問題

問題8：支付寶要重新生成私鑰和公鑰，並上傳修改公鑰 -- 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：“>”符號後面的才是需要輸入的命令。

生成的文件：

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

然後設置

/*
*商戶的唯一的parnter和seller。
*簽約後，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
//獲取私鑰並將商戶信息簽名,外部商戶可以根據情況存放私鑰和簽名,只需要遵循RSA簽名規范,並將簽名字符串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，繼續分享咯，總結才能讓問題越來越少！
