AFNetworking框架_上传文件或图片到服务器

文中的 XXXXXXXXXX更具你自己的参数填写

- (void)uploadImageWithImage:(NSString *)imagePath

{

//上传其他所需参数

NSString *userId=XXXXXXXXXXX;

NSString *token=XXXXXXXXXXX;

//上传请求POST

AFHTTPClient *client=[AFHTTPClient clientWithBaseURL:[NSURL URLWithString:@""]];

NSString *urlString=[NSString stringWithFormat:@"上传服务器地址];

NSDictionary *dic=[[NSDictionary alloc] initWithObjectsAndKeys:userId,@"XXXXXX",token,@"XXXXXX", nil];

NSURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:urlString parameters:dic constructingBodyWithBlock:^(id formData) {

//得到需要上传的数据

NSData *data=[NSData dataWithContentsOfFile:imagePath];

//上传时使用当前的系统事件作为文件名

NSDateFormatter *formatter = [[NSDateFormatter alloc] init];

formatter.dateFormat = @"yyyyMMddHHmmss";

NSString *str = [formatter stringFromDate:[NSDate date]];

NSString *fileName = [NSString stringWithFormat:@"%@.jpg", str];

/*

此方法参数

1. 要上传的[二进制数据]

2. 对应网站上[upload.php中]处理文件的[字段"file"]

3. 要保存在服务器上的[文件名]

4. 上传文件的[mimeType]

*/

//服务器上传文件的字段和类型

[formData appendPartWithFileData:data name:@"XXXXX" fileName:fileName mimeType:@"image/jpg/file"];

}];

// 3. operation包装的urlconnetion

AFHTTPRequestOperation *op = [[AFHTTPRequestOperation alloc] initWithRequest:request];

[op setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

NSLog(@"上传完成");

} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

NSLog(@"上传失败->%@", error);

}];

//执行

[client.operationQueue addOperation:op];

}
