SharePoint -- Download a Text File into a String Variable

See more SharePoint Examples

Demonstrates how to download a text file from SharePoint into a string variable.

Chilkat Objective-C Downloads

Objective-C
#import <CkoHttp.h>
#import <NSString.h>
#import <CkoBinData.h>
#import <CkoStringBuilder.h>

BOOL success = NO;

//  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"

CkoHttp *http = [[CkoHttp alloc] init];

//  If SharePoint Windows classic authentication is used, then set the 
//  Login, Password, LoginDomain, and NtlmAuth properties.
http.Login = @"SHAREPOINT_USERNAME";
http.Password = @"SHAREPOINT_PASSWORD";
http.LoginDomain = @"SHAREPOINT_NTLM_DOMAIN";
http.NtlmAuth = YES;

//  -------------------------------------------------------------------------
//  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.

NSString *url = @"https://SHAREPOINT_HTTPS_DOMAIN/_api/web/GetFileByServerRelativeUrl('/Documents/ChilkatTest/japanese.csv')/$value";

http.AcceptCharset = @"utf-8";

NSString *strCsv = [http QuickGetStr: url];
if (http.LastMethodSuccess != YES) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

//  The CSV file is contained in strCsv.
NSLog(@"%@",@"CSV:");
NSLog(@"%@",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:  

CkoBinData *bd = [[CkoBinData alloc] init];
success = [http QuickGetBd: url binData: bd];
if (success != YES) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

//  Interpret the bytes correctly as utf-8
CkoStringBuilder *sb = [[CkoStringBuilder alloc] init];
[sb AppendBd: bd charset: @"utf-8" offset: [NSNumber numberWithInt: 0] numBytes: [NSNumber numberWithInt: 0]];
NSLog(@"%@",@"CSV:");
NSLog(@"%@",[sb GetAsString]);
