ERP是企業資源計劃系統的簡稱,其主要作用是對企業的資源進行管理和協調、協同。隨著企業的不斷發展壯大,ERP系統的深入應用也越來越受到重視。其中,與ERP進行對接的編程語言非常多,而PHP作為一款廣泛應用的編程語言,其對接ERP也同樣非常熟悉。
在ERP對接PHP的過程中,我們可以利用各個ERP平臺的API接口進行數據交互。下面我們以SAP作為例子,來介紹ERP對接PHP的操作步驟:
1. 首先,在SAP ERP中創建一個Web service。代碼示例:
DATA: g_sap_url TYPE string, g_soap_action TYPE string, g_endpoint TYPE string. g_sap_url = 'http://192.168.10.100:8000/sap/bc/srt/wsdl/bndg_URL/P_01/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx?sap-client=800'. g_soap_action = 'urn:sap-com:document:sap:rfc:functions'. g_endpoint = 'http://192.168.10.100:8000/sap/bc/srt/rfc/sap/erp_webservice_name/800/erp_webservice_name/erp_webservice_name_binding'; CALL METHOD CL_HTTP_CLIENT=>CREATE_BY_URL EXPORTING URL = g_sap_url AUTHORITY_HOST = '192.168.10.100' AUTHORITY_PORT = 8000 RECEIVING CLIENT = HTTP_CLIENT. CALL METHOD HTTP_CLIENT->REQUEST EXPORTING METHOD = 'POST' URL = g_endpoint HTTP_HEADER_FIELDS = header_fields ENCODING = 'UTF-8' IMPORTING RESPONSE_CODE = response_code REASON_PHRASE = reason_phrase HTTP_HANDLE = http_handle LAST_HTTP_CLIENT_EXCEPTION = last_exception TIMEOUT = 60. CALL METHOD CL_HTTP_UTILITY=>CHECK_RESPONSE_STATUS_CODE EXPORTING HTTP_STATUS_CODE = response_code EXCEPTIONS HTTP_STATUS_CODE_ERROR = 1. CALL METHOD cl_soap_message_factory=>create_request EXPORTING method = 'Get_Items_From_Store' namespace = 'urn:SAP:Name_of_Web_Service' CHANGING message = soap_request. CALL METHOD cl_http_message=>set_body EXPORTING request = soap_request RECEIVING message = http_request. CALL METHOD HTTP_CLIENT->SEND EXPORTING REQUEST = http_request RECEIVING RESPONSE = http_response. CALL METHOD CL_HTTP_UTILITY=>CHECK_RESPONSE_STATUS_CODE EXPORTING HTTP_STATUS_CODE = HTTP_RESPONSE->STATUS_CODE EXCEPTIONS HTTP_STATUS_CODE_ERROR = 1. CALL METHOD cl_soap_message=>create_response EXPORTING soap_message = http_response CHANGING message = soap_response.在以上代碼中,我們創建了一個Web service并設置了訪問地址、SOAP動作、終結點等參數。然后發送HTTP請求,并將SOAP消息傳入HTTP正文中。在接收到響應后,我們還需要對響應進行處理,獲取到其中的SOAP消息。 2. 接下來,我們將SOAP消息解析成PHP對象,以便我們能夠對消息進行操作。代碼示例:
$response = simplexml_load_string($soap_response); print_r($response);這里我們使用了PHP內置的simplexml_load_string()函數,將$soap_response變量中的SOAP消息解析成PHP對象,并進行了打印輸出。這樣我們就可以對SOAP消息中的字段進行讀取和操作。 3. 最后,我們將PHP對象中的數據發送到我們的數據庫等其他系統中。代碼示例:
$conn = mysqli_connect($servername, $username, $password, $dbname); mysqli_set_charset($conn,"utf8"); $stmt = $conn->prepare("INSERT INTO products (name, quantity, price) VALUES (?, ?, ?)"); $stmt->bind_param("sii", $name, $quantity, $price); foreach ($response->body->Get_Items_From_StoreResponse->Results->Product as $product) { $name = $product->Name; $quantity = $product->Quantity; $price = $product->Price; $stmt->execute(); } $stmt->close(); $conn->close();在以上代碼中,我們將SOAP消息中的Product對象中的Name、Quantity和Price字段取出,并存儲到數據庫中。 總結來講,ERP對接PHP的過程主要是通過API接口來進行數據交互,以滿足企業內統一資源管理的需求。在具體操作過程中,我們需要根據不同的ERP平臺和數據類型來選擇合適的方法進行處理,同時也需要注意對接過程中可能出現的異常情況,以保證接口的穩定性和可靠性。
