This article is about how to get started with the php version of Bank of Communications online bank payment interface development. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article. Let's take a look at it.

Summary: the online bank payment interface and Alipay interface are generally similar, the main difference is that the core of the interface provided by the Bank of Communications, for example, encryption is achieved through java, so, to find a way to make php and java can communicate normally, to this end, the official also provides two sets of implementation methods, one is to communicate through socket, the other is to bridge through java, the following is a demonstration of socket method.

1. Configure the running environment

1.1 install java, download java from oracle website, then install and configure the correct environment variables.

1.2 Import the test certificate into the java virtual machine.

Keytool "- import-keystore" address where the java virtual machine places the certificate "- storepass changeit-alias test_bocommca-file" Certificate path completes the import.

Example: keytool "- import-keystore" C:\ Program Files\ Java\ jre1.5\ lib\ security\ cacerts "- storepass changeit-alias test_bocommca-file" C:\ socket\ cert\ test_root.cer "

1.3 modify the configuration file (in/B2CMerchantSocket.xml).

When testing with an official test firm, there is no need for configuration, otherwise it should be configured, as described in the xml file.

1.4 start the socket service

Window: start start.bat and can.

Linux: start ohup sh.start,sh& / / to detach the current script from the terminal and run it in the background.

two。 Integrate the network bank into the existing system and explain it with the structure of mvc.

2.1 write the unchanged parameter configuration to the configuration file:

$config ['interfaceVersion'] = "1.0.0.0"; # Interface version $config [' tranType'] = 0; # transaction category 0:B:C$config ['curType'] =' CNY'; # transaction currency $config ['notifyType'] = 1; # 0 = No Notification 1 = Notification 2 = crawling $config [' merURL'] = "/ pay/notify"; # proactive Notification url$config ['goodsURL'] =' / goods/1.html'; # pickup url$config ['jumpSeconds'] = 3 # Jump time $config ['payBatchNo'] =''; # Merchant batch number $config ['proxyMerName'] =''; # Agent merchant name $config ['proxyMerType'] =''; # Agent type $config ['proxyMerCredentials'] =''; # Agent vendor batch number $config ['netType'] = 0; # Channel number / below is the parameter required for the new interface $config [' socketUrl'] = "tcp://127.0.0.1:8891" # socket url$config ['merID'] =' 301310063009501; # merchant id 3013100630095012

2.3 Controller

$this- > load- > model ("Bocom")

Method of payment:

$this- > arrData = $this- > Bocom- > pay ($this- > data)

Notification:

$this- > arrData = $this- > Bocom- > notify (); the above is how to get started with the php version of Bank of Communications online bank payment interface development.
