(Unicode C) SharePoint -- Download a Text File into a String VariableSee more SharePoint ExamplesDemonstrates how to download a text file from SharePoint into a string variable.
#include <C_CkHttpW.h> #include <C_CkBinDataW.h> #include <C_CkStringBuilderW.h> void ChilkatSample(void) { HCkHttpW http; const wchar_t *url; const wchar_t *strCsv; HCkBinDataW bd; BOOL success; HCkStringBuilderW sb; // This requires the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // ------------------------------------------------------------------------- // The following comments apply to SharePoint Windows classic authentication. // ------------------------------------------------------------------------- // For example, imagine our SharePoint endpoint is https://xyzoffice.mycompany.com/ // The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com" // The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com" // Also, the SHAREPOINT_USERNAME would be just the name, not a full email address. // for example, "chilkat" instead of "chilkat@mycompany.com" http = CkHttpW_Create(); // If SharePoint Windows classic authentication is used, then set the // Login, Password, LoginDomain, and NtlmAuth properties. CkHttpW_putLogin(http,L"SHAREPOINT_USERNAME"); CkHttpW_putPassword(http,L"SHAREPOINT_PASSWORD"); CkHttpW_putLoginDomain(http,L"SHAREPOINT_NTLM_DOMAIN"); CkHttpW_putNtlmAuth(http,TRUE); // ------------------------------------------------------------------------- // The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie). // If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead // establish the cookie as shown at SharePoint Online Authentication // ------------------------------------------------------------------------- // This example downloads a CSV file that is utf-8 and contains Japanese characters. url = L"https://SHAREPOINT_HTTPS_DOMAIN/_api/web/GetFileByServerRelativeUrl('/Documents/ChilkatTest/japanese.csv')/$value"; CkHttpW_putAcceptCharset(http,L"utf-8"); strCsv = CkHttpW_quickGetStr(http,url); if (CkHttpW_getLastMethodSuccess(http) != TRUE) { wprintf(L"%s\n",CkHttpW_lastErrorText(http)); CkHttpW_Dispose(http); return; } // The CSV file is contained in strCsv. wprintf(L"CSV:\n"); wprintf(L"%s\n",strCsv); // Note: The HTTP response hopefully indicates the charset of the response, // and Chilkat should receive the string correctly. If the response sent by // SharePoint does not indicate a charset, or indicates an incorrect charset, // then we can instead download the text file as binary data and interpret the // bytes ourselves correctly. For example: bd = CkBinDataW_Create(); success = CkHttpW_QuickGetBd(http,url,bd); if (success != TRUE) { wprintf(L"%s\n",CkHttpW_lastErrorText(http)); CkHttpW_Dispose(http); CkBinDataW_Dispose(bd); return; } // Interpret the bytes correctly as utf-8 sb = CkStringBuilderW_Create(); CkStringBuilderW_AppendBd(sb,bd,L"utf-8",0,0); wprintf(L"CSV:\n"); wprintf(L"%s\n",CkStringBuilderW_getAsString(sb)); CkHttpW_Dispose(http); CkBinDataW_Dispose(bd); CkStringBuilderW_Dispose(sb); } |
