AFNetworking上传文件 [英] AFNetworking Uploading a file
问题描述
是否有人使用AFNetworking完全上传文件。我在互联网上找到了一些代码，但它不完整。我找到的代码在这里：
Does any one have a full implementation of uploading a file using AFNetworking. I have found some code on the internet but it is incomplete. The code I have found is here:
AFHTTPClient *client= [AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@"http://my.client.server.com"]];
NSMutableDictionary *parameters = [NSMutableDictionary dictionary];
[parameters setObject:[fieldName text] forKey:@"field01_nome"];
[parameters setObject:[fieldSurname text] forKey:@"field02_cognome"];
NSMutableURLRequest *myRequest = [client multipartFormRequestWithMethod:@"POST" path:@"/Contents/mail/sendToForm.jsp" parameters:parameters constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) {
[formData appendPartWithFileData:myNSDataToSend mimeType:@"image/jpeg" name:@"alleagto"];
}];
AFHTTPRequestOperation *operation = [AFHTTPRequestOperation HTTPRequestOperationWithRequest:myRequest success:^(id object) {
NSLog(@"Success");
} failure:^(NSHTTPURLResponse *response, NSError *error) {
NSLog(@"Fail");
}];
[operation setUploadProgressBlock:^(NSInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) {
NSLog(@"Sent %d of %d bytes", totalBytesWritten, totalBytesExpectedToWrite);
}];
queue = [[[NSOperationQueue alloc] init] autorelease];
[queue addOperation:operation];
我在以下几行收到错误：
I get errors on the following lines:
[formData appendPartWithFileData:myNSDataToSend mimeType:@"image/jpeg" name:@"alleagto"];
在myNSDataToSend。
At the myNSDataToSend.
在这里：
AFHTTPRequestOperation *operation = [AFHTTPRequestOperation HTTPRequestOperationWithRequest:myRequest success:^(id object) {
NSLog(@"Success");
} failure:^(NSHTTPURLResponse *response, NSError *error) {
NSLog(@"Fail");
}];
错误是：
类方法'+ HTTPRequestOperationWithRequest：成功：失败'未找到（返回类型默认为'id'）
Class method '+HTTPRequestOperationWithRequest:success:failure' not found(return type defaults to 'id')
任何有关此问题的帮助以及使用AFNetworks上传都会令人惊叹。
Any help on this and uploading with AFNetworks would be amazing.
谢谢。
推荐答案
首先，确保已下载最新版本的AFNetworking 。
First, make sure you have the latest version of AFNetworking downloaded.
AFHTTPRequestOperation + HTTPRequestOperationWithRequest：成功：失败：已删除几个版本。相反，您可以执行 [[AFHTTPRequestOperation alloc] initWithRequest：...] 然后设置 completionBlock 直接属性访问器（ operation.completionBlock = ^ {...} ），或者带有 -setCompletionBlockWithSuccess：失败：。请记住，请求完成下载后会执行完成块。
AFHTTPRequestOperation +HTTPRequestOperationWithRequest:success:failure: was removed a few versions back. Instead, you can do [[AFHTTPRequestOperation alloc] initWithRequest:...] and then set the completionBlock with either the straight property accessor (operation.completionBlock = ^{...}), or with -setCompletionBlockWithSuccess:failure:. Keep in mind that completion blocks execute after the request has finished downloading.
对于多部分表单块， -appendWithFileData：mimeType：name 也被删除了一段时间。您想要的方法是 -appendPartWithFileData：name：fileName：mimeType：。
As for the multipart form block, -appendWithFileData:mimeType:name was also removed a while back. The method you want is -appendPartWithFileData:name:fileName:mimeType:.
进行这两项更改，一切都应该有效。
Make those two changes and everything should work.
