Hi,

I'd like to use HTTP classes to load an image from the web then save it as an Attachment and finally send it attached to an email. At first glance everything seems to work fine. But the picture I receive is obviously a corrupt file. Any ideas what's wrong with my code:

public class EmailTestCtr {
	
	public Integer totalFileSize {get; set;}
	public Email__c mail {get; set;}
	public String contentType {get; set;}
	public String response {get; set;}
	
	public EmailTestCtr(){
		totalFileSize = 0;
	}
	
	public void loadFile(){
		String url = '';
		
		Http h = new Http();
		HTTPRequest req = new HttpRequest();
        
        req.setEndpoint('http://www.clienthouse.com/images/f106e78f34/CH_location_web1.jpg');
        req.setMethod('GET');
        req.setCompressed(false);
		
		HTTPResponse resp = h.send(req);
		this.contentType = resp.getHeader('Content-Type');
		this.response = resp.getHeader('Content-Length');
		
		System.debug(resp.getBody());
		String body = resp.getBody();
		
		Attachment a = new Attachment();
		try {		
			if(this.mail == null){
				mail = new Email__c(
					Name = 'test'
				);
				insert mail;
			}
			
			a.Body = Blob.valueOf(body);
			a.Name = 'Name';
			a.ParentId = mail.Id;
			a.ContentType = this.contentType;
			insert a;
		} catch(DMLException e){
			ApexPages.addMessages(e);
		}
		
		this.totalFileSize += [select BodyLength from Attachment where Id = :a.Id].BodyLength;
		
	}
	
	public void sendEmail(){
		
		Messaging.SingleEmailMessage email = new Messaging.SingleEmailMessage();
		String[] toAddresses = new String[] {'h.hess@clienthouse.com'};
		email.setToAddresses(toAddresses);
		email.setSubject(this.mail.Name);
		email.setPlainTextBody('Text goes here.');
		List<Messaging.EmailFileAttachment> files = new List<Messaging.EmailFileAttachment>();
		for(Attachment file : [select Name, Body, ContentType from Attachment where ParentId = :this.mail.Id]){
			System.debug('------------>FILE' + file);
			Messaging.EmailFileAttachment efa = new Messaging.EmailFileAttachment();
			efa.setBody(file.Body);
			efa.setContentType(file.ContentType);
			efa.setFileName(file.Name + '.jpg');
			files.add(efa);
		}
		email.setFileAttachments(files);
		
		Messaging.sendEmail(new Messaging.SingleEmailMessage[] { email });
		
	}
	
}

Thanks and best regards,

Henry
