I've looked into a good number of articles on how to do a multipart/form-data POST on iOS, but none really explain what to do if there were normal parameters as well as the file upload.
I have used the multipart/form-data POST on iOS & I had written the following code and it is uploading data but not image data
- (void)postWithImage:(NSDictionary *)dictionary
{
NSString *urlString = [NSString stringWithFormat:@"YourHostString"];
NSURL *url = [NSURL URLWithString:urlString];
NSString *boundary = @"----1010101010";
// define content type and add Body Boundry
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
NSEnumerator *enumerator = [dictionary keyEnumerator];
NSString *key;
NSString *value;
NSString *content_disposition;
while ((key = (NSString *)[enumerator nextObject])) {
if ([key isEqualToString:@"file"]) {
value = (NSString *)[dictionary objectForKey:key];
NSData *postData = UIImageJPEGRepresentation([UIImage imageNamed:value], 1.0);
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\";\r\nfilename=\"screen.png\"\r\n\r\n",value] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:postData];
} else {
value = (NSString *)[dictionary objectForKey:key];
content_disposition = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"%@\"\r\n\r\n", key];
[body appendData:[content_disposition dataUsingEncoding:NSUTF8StringEncoding]];
NSError *error;
NSData *jsonData = [NSJSONSerialization dataWithJSONObject:value options:NSJSONWritingPrettyPrinted error:&error];
[body appendData:jsonData];
//[body appendData:[value dataUsingEncoding:NSUTF8StringEncoding]];
}
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
}
//Close the request body with Boundry
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
[request addValue:[NSString stringWithFormat:@"%d", body.length] forHTTPHeaderField: @"Content-Length"];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"%@", returnString);
}
Can anyone please help me to get why image data is not uploading
