User manual AXIS APPINT

[. . . ] However, if some of the conditions are not met, e. g. the scanner is busy, the response will contain the complete 7GER (SGYQIRX page, including an error message at the top. If you received the 1SZIH 8IQTSVEVMP] response, you should send a +)8 request to get the URL you received in the response. Follow the steps below to scan an image to your application using your AXIS 700. [. . . ] Create a query string containing the parameters you want to send: CString aQueryString = "\n\npage=scan&profileName=Color+low&scanNow="; 5. Add an HTTP header which informs the HTTP server that the request contains encoded data: anHttpFile->AddRequestHeaders( "Content-type: application/x-www-form-urlencoded"); 5 6. Send the request: anHttpFile->SendRequest(NULL, 0, (void*)(const char*)aQueryString, aQueryString. GetLength()); The method will not return ?????until a response is received from the server or after a time out. If the request is successful, image data will be sent back. Otherwise an HTML page containing error information will be sent. One way of testing what was sent back is to look at the Content-type. Its value can be retrieved by the following call: anHttpFile->QueryInfo(HTTP_QUERY_CONTENT_TYPE, aContType); If all went well, aContType will have the value "image/jpeg" (if JPEG is the chosen format. See table above. ), otherwise "text/html". Finally we are ready to receive the data: UINT bytesRead = anHttpFile->Read(buffer, MAXBUF - 1); while( nBytesRead > 0) { //Save data somewhere . //Read next chunk nBytesRead = anHttpFile->Read(buffer, MAXBUF -1); } Scanning Using the WinInet API If you do not want to use MFC to create an Internet application you can use the WinInet API instead. It provides basically the same functionality as MFC does and the functions in the WinInet API are very similar to those in MFC. In the steps below we describe how the API is used. For more information, see the WinInet documentation. The following code is not checked for errors. Call InternetOpen to enable an Internet connection: HINTERNET anInetHandle = InternetOpen("ScanSDK", INTERNET_OPEN_TYPE_DIRECT, NULL, NULL, 0); 6 2. Create an HTTP handle by calling the InternetConnect function with the necessary parameters: HINTERNET anHTTPHandle = InternetConnect(anInetHandle, "171. 16. 1. 185", INTERNET_DEFAULT_HTTP_PORT, "root", "pass", INTERNET_SERVICE_HTTP, 0, 0); 3. The second parameter indicates that it is a 4378 request and the third indicates that the target is the '/user/scan/scan. shtml' page. By default, redirect responses are handled automatically: HINTERNET anHttpRequest = HttpOpenRequest(anHTTPHandle, "POST", "/user/scan/scan. shtml", NULL, NULL, NULL, 0, 0); 4. Add an HTTP header which informs the HTTP server that the request contains encoded data: char aReqStr[] = "Content-type: application/x-www-form-urlencoded"; HttpAddRequestHeaders(anHttpRequest, aReqStr, strlen(aReqStr), 0) 5. Create a query string containing the parameters you want to send and send the request: char aQeryStr[] = "\n\npage=scan&profileName=Color+low&scanNow="; HttpSendRequest(anHttpRequest, 0, 0, aQeryStr, strlen(aQeryStr)) 7 6. If the request is successful, image data will be sent back. [. . . ] The file name may then be on the form name_lastNameXXX. tif, where XXX is the sequence number optionally appended by your AXIS 700. Your application can now decide whom to send the image to. )\EQTPI A fax server application can use the image name to obtain the fax number, and the file format to decide how to convert the document to fax data. See the AXIS 700 Additional Installation Note, Setting Up Your AXIS 700 for Scan-to-File for information on how to define Scan-to-File destinations. 9 Accessing the List of Scanning Profiles The profiles list is stored in the config. ini file, along with all other parameters.
