I want to integrate tinypng api into one of my iOS app. But I can not find any materials on their website on how to write objective-c code or convert from curl command to upload the file for processing. The curl api is below:
curl --user api:YOUR_API_KEY \
--data-binary #unoptimized.png -i https://api.tinify.com/shrink
I have tried on writing http post code for it,
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:TINY_PNG_HOST]
cachePolicy:NSURLRequestReloadIgnoringCacheData
timeoutInterval:8.f];
request.HTTPMethod = #"POST";
NSString *base64encodedKey = [[[NSString stringWithFormat:#"api:%#", apiKey] dataUsingEncoding:NSUTF8StringEncoding] base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithCarriageReturn];
NSString *auth = [NSString stringWithFormat:#"Basic %#", base64encodedKey];
[request setValue:auth forHTTPHeaderField:#"Authorization"];
NSData *imageData = UIImageJPEGRepresentation(obj.imageIcon, 1);
NSString *boundary = #"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:#"rn--%#rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Disposition: form-data; name=\"wigi_item_image\";filename=\"item.jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Type: image/jpeg\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Transfer-Encoding: binary\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:#"rn--%#--rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration: defaultConfigObject delegate: self delegateQueue: [NSOperationQueue mainQueue]];
NSURLSessionDataTask * dataTask = [defaultSession dataTaskWithRequest:request];
[dataTask resume];
but always got a failed result. I think something was wrong with uploading image through setHTTPBody method.
how can I solve the problem?

Is FileParamConstant name is backend side multipath image folder name? It is same name I have set but why it's not working?
Below code is perfectly working , and yes FileParamConstant is the name of your backend side folder where image is store:
NSMutableDictionary * dictParam = [[NSMutableDictionary alloc]init];
[dictParam setObject:[dlf objectForKey:KEY_LOGIN_USER_ID] forKey:#"userId"];
[dictParam setObject:FirstNametextField.text forKey:#"first_name"];

[dictParam setObject:MobileNumbertextField.text forKey:#"contact_no"];
[dictParam setObject:AddressTetField.text forKey:#"address"];
[dictParam setObject:photoselect forKey:#"is_upload"];
NSString *strUrl=[NSString stringWithFormat:#"%#update_worker_profile?",WEB_SERVICE_URL];
// the boundary string : a random string, that will not repeat in post data, to separate post data fields.
NSString *BoundaryConstant = #"----------V2ymHFg03ehbqgZCaKO6jy";
// string constant for the post parameter 'file'. My server uses this name: `file`. Your's may differ
NSString* FileParamConstant = #"picture";
// the server url to which the image (or the media) is uploaded. Use your server url here
NSURL* requestURL = [NSURL URLWithString:strUrl];
// create request
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:30];
[request setHTTPMethod:#"POST"];
// set Content-Type in HTTP header
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#", BoundaryConstant];
[request setValue:contentType forHTTPHeaderField: #"Content-Type"];
// post body
NSMutableData *body = [NSMutableData data];
// add params (all params are strings)
for (NSString *param in dictParam) {
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", BoundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"\r\n\r\n", param] dataUsingEncoding:NSUTF8StringEncoding]];

I have implemented code for nginx upload file to server using NSURLSession for speed test. This is working properly on iOS 8 but on iOS 10 it is giving status code 413 (request entity too large).
File size is approx 30MB, If file size is less then 1MB it's working properly. Here is my code
NSString *BoundaryConstant = #"----------V2ymHFg03ehbqgZCaKO6jy";
NSString* FileParamConstant = #"file";
NSURL* requestURL = [NSURL URLWithString:kPathForUploadCheck];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setCachePolicy:NSURLRequestReloadIgnoringLocalCacheData];
[request setHTTPShouldHandleCookies:NO];
[request setTimeoutInterval:600];
[request setHTTPMethod:#"POST"];
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#", BoundaryConstant];
[request setValue:contentType forHTTPHeaderField: #"Content-Type"];
NSMutableData *body = [NSMutableData data];
NSString *path = [[NSBundle mainBundle] pathForResource:#“myfile” ofType:#"psd"];
NSData *imageData22 = [NSData dataWithContentsOfFile:path];
NSString *base64String = [imageData22 base64EncodedStringWithOptions:0];
NSData *imageData = [base64String dataUsingEncoding:NSUTF8StringEncoding];
if (imageData) {

Hi i am trying to upload an image through multipart to server in objective c using NSURLSession. But i am getting few errors like
org.apache.commons.fileupload.FileUploadException: Header section has more than 10240 bytes (maybe it is not properly terminated)
Below is my objective c code:
{
NSString *boundaryConstant = #"----------V2ymHFg03ehbqgZCaKO6jy";
NSString *fileParamConstant = #"photo";
NSMutableURLRequest *req = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:url]];
[req setHTTPMethod:#"POST"];
NSString *contentType = [NSString stringWithFormat:#"multipart/form-data;boundary=%#",boundaryConstant];
[req setValue:contentType forHTTPHeaderField:#"Content-Type"];
NSMutableData *body = [NSMutableData data];
if (imageData) {
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"Content-Disposition: form-data; name=\"%#\"; filename=\"%#\"\r\n", fileParamConstant, fileName] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:imageData];
[body appendData:[[NSString stringWithFormat:#"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:#"--%#--\r\n", boundaryConstant] dataUsingEncoding:NSUTF8StringEncoding]];
NSString *bodyLength = [NSString stringWithFormat:#"%zu",[body length]];
[req setValue:bodyLength forHTTPHeaderField:#"Content-Length"];
[req setHTTPBody:body];
NSURLSession *session = [NSURLSession sessionWithConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration] delegate:nil delegateQueue:nil];
NSURLSessionUploadTask *uploadTask = [session uploadTaskWithRequest:req fromData:body completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
NSLog(#"STRING %#", [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]);
}];
[uploadTask resume];
}
}
Any help would be greatly appreciated.
Thanks
I want to upload the image to the server.The services for the server is written in .NET. Now server asks me to send the image as bytes of data not as multipart.I am uploading the file by below code.I get response as file uploaded but image is not shown.
[request setURL:[NSURL URLWithString:url]];
[request setHTTPMethod:#"POST"];
NSMutableData *body = [NSMutableData data];
NSString *boundary = #"---------------------------14737809831466499882746641449";
//NSString *contentType = [NSString stringWithFormat:#"multipart/form-data; boundary=%#",boundary];
//[request addValue:contentType forHTTPHeaderField: #"Content-Type"];
[body appendData:[[NSString stringWithFormat:#"--%#\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Disposition: form-data; name=\"host_pic\"; filename=\"parkN.png\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[#"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:postData];
[body appendData:[#"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
// close form
[body appendData:[[NSString stringWithFormat:#"--%#--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
Please explain what could be the issue.How can i uplaod such file.
then you could try to POST JSON format.

} else {
}
}];
[uploadTask resume];
return response;
}
But my Server always responds File not Found! Is that not correct code?!

And here is the php part that works for me.
<?php
$target_path = "./uploads/";
$target_path = $target_path . basename( $_FILES['picture']['name']);
if(move_uploaded_file($_FILES['picture']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['picture']['name'])." has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
}
?>
