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:
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];
我在以下几行中遇到错误:
[formData appendPartWithFileData:myNSDataToSend mimeType:@"image/jpeg" name:@"alleagto"];
在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')
任何有关此问题的帮助以及使用AFNetworks上传都会令人惊叹。
感谢。

首先,请确保已下载最新版本的AFNetworking。
AFHTTPRequestOperation +HTTPRequestOperationWithRequest:success:failure:
已删除了几个版本。相反,您可以执行[[AFHTTPRequestOperation alloc] initWithRequest:...]
,然后使用直属性访问者(completionBlock
)或operation.completionBlock = ^{...}
设置-setCompletionBlockWithSuccess:failure:
。请记住,在请求下载完成后执行完成块。
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:
。
进行这两项更改,一切都应该有效。
