First, the brief scene
Before doing the micro-channel payment to the bank card business functions, but to the customer after the play money, the next day before arrival, for the timely feedback, so he made a "query to the enterprise if the payment was credited into account" function. This piece, I wrote a class directly, for processing, the following is the entire class code!
Micro-channel document: https: //pay.weixin.qq.com/wiki/doc/api/tools/mch_pay.php chapter = 24_3?
Second, pay attention to the relevant
1, here involves some sensitive configuration in the configuration file, and, "to the enterprise query whether the payment credited into account" the need to use certificates, the need to prepare in advance, remember!
2, partner_trade_no parameter is a string of characters in the play money to the bank card account is generated when the client, the results of data you can store your own, you can also return from a micro-channel in the end get.
3, check whether the arrival, arrival situation is return_code, result_code, err_code whole is true, pay_succ_time not empty, it indicates arrival!
Third, the core code

Fourth, written in the last
Beginning to see the document, I felt micro-channel document, written or not so do the will of man, so read it several times, have understood, the key point is that "signature generation," It should be noted that, in addition, by Curl function when transferring data, will use the certificate, the document mentioned here, but still in this place, tangled for a long time! In short, this involves the payment of micro-channel are more stringent, requires careful understanding of the process!
