erp 對接php

謝彥文1年前7瀏覽0評論
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。
