What should I do if the WeChat payment verification signature developed by ios fails?
& ltxml & gt& ltreturn _ code & gt& lt！ [CDATA[ Failed] ]]& gt；; & lt/return _ code & gt； & ltreturn _ msg & gt& lt！ [CDATA[ Signature error] ]]& gt；; & lt/return _ msg & gt； & lt/XML & gt；
I have always encountered "signature error" when debugging the "unified order" interface of WeChat payment. I found all kinds of information on the internet, which may generally be the following questions. If you make this mistake, you might as well check it one by one to avoid wasting time and detours.
The ASCII code of the 1. parameter name is not in ascending order, or the generated MD5 string is not converted from uppercase to lowercase. The solution to this problem is simple. Just check it on WeChat official website with the checking tool.
2. Wrong key. Pay special attention here, the key of the public platform and the key of the merchant number are different! After the approval of WeChat payment is successful, you will receive an email with appid merchant number, merchant background login number and password, log in to the merchant background: account settings-security settings-switch to api security, download the certificate, there is an API key below, fill in a string, save, and use this manually set key to sign the next two times!
Finally, I would like to remind you that you must read the emails and documents carefully in the future.
Wechat payment failed. What should I do if I can't pay? If I bind the bank card, I can pay.
1. In WeChat, you may not find a channel for WeChat payment, and there is no entrance to bind the bank card. In fact, when you pay for the first time, you will be provided with the entrance to bind the bank card. After binding, you can complete WeChat payment in other public accounts.
2. Now let's complete the first payment operation of binding the bank card. Switch to the "Me" interface in the main interface of WeChat, and then click the "Expression Store" option in the list item, as shown in the figure.
3. Choose a set of expressions in the new interface to buy, such as "rice ball and his friends", and click the price button on the right to buy this set of expressions (not really buying, just showing you how to bind the bank card).
4. Click the "Pay" button to start using WeChat payment, and you need to bind the bank card when paying. Please enter the cardholder's bank card number and click Next.
5. Enter personal information such as bank card type, bank reserved cardholder's name, ID card and mobile phone number. You will receive the SMS verification code later, and WeChat will automatically get the SMS verification code. Just click the "Next" button.
6. The following operations need to set a 6-digit password for WeChat secure payment, which needs to be executed by the user himself, and I don't need to go into details. I believe you already know how to bind the bank card! Remember not to follow through, or you will really buy 6 yuan's expression.
7. After binding the bank card for quick payment, you don't need to bind it again when you make WeChat payment and scan the QR code and App in WeChat official account next time, just enter the payment password to complete the payment. You can view it in "I->"; Personal avatar-> Personal information-> Manage the bound bank card or add a new bank card under my bank card.
If the WeChat red envelope can't be sent out, it always prompts that the payment failed. First of all, if the bank card has not been added, the amount of change payment is: RMB 200 yuan for one day and RMB 500 yuan for one month.
