我无法通过HTTPS POST请求将图像上传到Cloudinary托管，我想使用简单的API方法而不是SDK。我在将图像格式化为字节数组缓冲区中或作为Base64编码时遇到问题。
这是我的代码:
UIImage *image = [UIImage imageNamed:@"image.png"];
NSData *imageData = UIImagePNGRepresentation(image);
NSString *strImageData = [imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
NSURL *url = [NSURL URLWithString:@"https://api.cloudinary.com/v1_1/MYSECTER/image/upload"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPMethod = @"POST";
NSString *strRequest = [NSString stringWithFormat:@"file=%@&upload_preset=MYSECTER", strImageData];
request.HTTPBody = [strRequest dataUsingEncoding:NSUTF8StringEncoding];
[[[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
NSDictionary *recievedData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error];
NSLog(@"RECEIVED: %@", recievedData);
}] resume];
不幸的是，我从服务器收到以下答复:“不支持的源URL ...”
我确实尝试了很多其他方法，但无法使其正常工作。
更新:当我将URL链接放在'file'参数中时，一切正常。
最佳答案
我没有Cloudinary API的经验，但我希望这会有所帮助。我看了'Uploading with a direct call to the API'上的文档。
我认为您需要提供“文件”和“upload_preset”作为POST参数(而不是在正文中串联为数据)。
UIImage *image = [UIImage imageNamed:@"image.png"];
NSData *imageData = UIImagePNGRepresentation(image);
NSString *strImageData = [imageData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];
NSURL *url = [NSURL URLWithString:@"https://api.cloudinary.com/v1_1/MYSECTER/image/upload"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
request.HTTPMethod = @"POST";
// Replace this:
//NSString *strRequest = [NSString stringWithFormat:@"file=%@&upload_preset=MYSECTER", strImageData];
//request.HTTPBody = [strRequest dataUsingEncoding:NSUTF8StringEncoding];
// With this:
NSString *imageDataStr = [[NSString alloc] initWithData:imageData encoding:NSUTF8StringEncoding];
[request setValue:imageDataStr forHTTPHeaderField:@"file"];
[request setValue:@"MYSECTER" forHTTPHeaderField:@"upload_preset"];
[[[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
NSDictionary *recievedData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:&error];
NSLog(@"RECEIVED: %@", recievedData);
}] resume];
