我正在寻找一些导致我的问题。 我几乎查看了与将图像发布/上传到服务器相关的所有链接，但似乎没有任何代码可以使我的代码正常工作。
我已经以不同的方式发布了2个选项...注释的代码表明...我的请求对服务器是空白的。
我尝试过使用不同的选项 - appendPartWithFormData，appendPartWithFileData。
选项1
NSError *错误;
// Create paths to output images
NSString *pngPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/Test.png"];
UIImage *image = [UIImage imageWithData:self.imageData];
[UIImagePNGRepresentation(image) writeToFile:pngPath atomically:YES];
NSURL *imagePath = [NSURL fileURLWithPath:pngPath];
NSData *jsonInputData = [NSJSONSerialization dataWithJSONObject:[requestParameter valueForKey:@"Param"] options:0 error:&error];
NSString *jsonInputString = [[NSString alloc] initWithData:jsonInputData encoding:NSUTF8StringEncoding];
NSLog(@"converted JOSN Data %@",jsonInputString);
NSDictionary* params = @{@"request": jsonInputString };
[manager POST:[requestParameter valueForKey:@"methodName"] parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
//[formData appendPartWithFormData:self.imageData name:@"profilepic" ];
//[formData appendPartWithFileData:self.imageData name:@"profilepic" fileName:@"profilepic.png" mimeType:@"image/png"];
[formData appendPartWithFormData:jsonInputData name:@"request"];
[formData appendPartWithFileURL:[NSURL fileURLWithPath:pngPath]
name:@"File"
error:nil];
} progress:nil success:^(NSURLSessionDataTask *task, id responseObject) {
NSLog(@"Success: %@", responseObject);
[self requestSuccessed:responseObject];
} failure:^(NSURLSessionDataTask *task, NSError *error) {
NSLog(@"Error: %@", error);
[self requestFailed:error];
}];
选项2
NSError* error;
NSData *jsonInputData = [NSJSONSerialization dataWithJSONObject:[requestParameter valueForKey:@"Param"] options:0 error:&error];
NSString *jsonInputString = [[NSString alloc] initWithData:jsonInputData encoding:NSUTF8StringEncoding];
NSDictionary* params = @{@"request": jsonInputString };
AFURLSessionManager *manager1 = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:[NSString stringWithFormat:@“XXXXXXX”] parameters:nil error:nil];
req.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue];
// [req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[req setValue:@"application/json" forHTTPHeaderField:@"Accept"];
// [req setHTTPBody:[jsonInputString dataUsingEncoding:NSUTF8StringEncoding]];
NSMutableData *body = [NSMutableData data];
NSString *boundary = @"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Disposition: form-data; name=\"profile_pic\"; filename=\"pic.png\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:self.imageData];
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[req addValue:contentType forHTTPHeaderField: @"Content-Type"];
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"request\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:jsonInputString] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
// close form
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[req setHTTPBody:body];
[[manager1 dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
if (!error) {
NSLog(@"Reply JSON: %@", responseObject);
if ([responseObject isKindOfClass:[NSDictionary class]]) {
//blah blah
}
} else {
NSLog(@"Error: %@, %@, %@", error, response, responseObject);
}
}] resume];

试试这个，希望它能解决你的问题
// your parametes here
userInfoDict=[[NSMutableDictionary alloc] init];
[userInfoDict setValue:@"image" forKey:@"iamge"];
// if image is too large than the timeout intervel
// [_request setTimeoutInterval:1000];
_request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"api url" parameters:userInfoDict constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
{
//convert imahe into data
NSData* data = UIImagePNGRepresentation(yourImage);
[formData appendPartWithFileData:data name:@"api paramets name in which you want to post image" fileName:@"myImage.png" mimeType:@"image/png"];
} error:nil];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
_uploadTask = [manager
uploadTaskWithStreamedRequest:_request
progress:^(NSProgress * _Nonnull uploadProgress)
{
// This is not called back on the main queue.
// You are responsible for dispatching to the main queue for UI updates
dispatch_async(dispatch_get_main_queue(), ^{
//Update the progress view
[_playerProgress setProgress:uploadProgress.fractionCompleted];
NSLog(@"\n uploading image vlaues %f\n",uploadProgress.fractionCompleted);
// for uploading video in background
manager.attemptsToRecreateUploadTasksForBackgroundSessions=YES;
});
}
completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
if (error) {
NSLog(@"Error: %@", error);
// [_playerProgress setHidden:YES];
} else
{
NSLog(@"%@ ", response);
// after upload comnlete disablle background uploading
manager.attemptsToRecreateUploadTasksForBackgroundSessions=NO;
NSLog(@"\n\n REsponse Form Server %@\n\n",responseObject);
//[responseObject valueForKey:@"error"];
//remove temp file
NSError *error;
}
}
];
[_uploadTask resume];

这通常对我有用。您需要确保RESTful脚本选择正确的文件句柄。我不懂Java，但在PHP中我会这样做：$image = $_FILES["imagename"]["name"];
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:url parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
NSLog(@"Saving image file");
[formData appendPartWithFileData:UIImagePNGRepresentation(image) name:@"imagename" fileName:@"image.png" mimeType:@"image/png"];
} error:nil];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
manager.responseSerializer = [AFHTTPResponseSerializer serializer];
NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:^(NSProgress * _Nonnull uploadProgress) {
// This is not called back on the main queue.
// You are responsible for dispatching to the main queue for UI updates
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(@"JSON uploadProgress.fractionCompleted: %f", uploadProgress.fractionCompleted);
});
} completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) {
//NSLog(@"Error: %@", error);
NSLog(@"RESPONSE: %@ %@", response, responseObject);
if(error) {
NSLog(@"Error: %@", error);
} else {
NSString *responseString = [[[NSString alloc] initWithData:responseObject encoding:NSASCIIStringEncoding] mutableCopy];
NSLog(@"RESPONSE: %@", responseString);
}
}];
[uploadTask resume];
