想用ASIHttpRequest上传一个.stl的文件，几十K到70M之间的文件，用的下面这段代码
[uploadFile removeObjectAtIndex:0];//删除mac文件下的默认的.DS_Store
NSString *upFilePath = [NSString stringWithFormat:@"%@/%@",filePath,uploadFile[0]];//上传的文件全路径
ASIFormDataRequest *request=[ASIFormDataRequest requestWithURL:[NSURL URLWithString:@"xxxxx"]];
[request setRequestMethod:@"Post"];
[request addRequestHeader:DownLoad_TOKEN value:@"X-Auth-Token"];
[request setFile:filePath forKey:@"file"];
[request setDelegate:self];
[request startAsynchronous];
然后试了很多次我去看自己上传的空间没有东西，并且我也不知道哪个代理可以监视文件是否已经开始上传或或者伤处啊能成功与否，求大神解救！！！
你是向上传一张图片的么？ 为什么不去试试AFNetWorking? 以前培训学习的时候用过ASI上传不过好像没你这么复杂。下面是我上传头像外带参数的代码，你可以看看（AFNetwork写的。。不过应该差不多把。）
+(void)postAddActive:(NSString *)url : (NSMutableDictionary *) params: (NSData *) imageData: (void (^)(id t)) success{
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager.requestSerializer setTimeoutInterval:45];
[SVProgressHUD showWithStatus:@"请稍等上传中..."];
[manager POST:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
// NSData *data = UIImageJPEGRepresentation(imageTo, 0.7);
if(imageData !=nil){
[formData appendPartWithFileData:imageData name:[NSString stringWithFormat:@"file"] fileName:[NSString stringWithFormat:@"UploadeFile.png"] mimeType:@"image/png"];
}
} success:^(AFHTTPRequestOperation *operation,id responseObject) {
success(responseObject);
[SVProgressHUD showSuccessWithStatus:@"上传成功"];
[SVProgressHUD dismiss];
} failure:^(AFHTTPRequestOperation *operation,NSError *error) {
if (![operation isCancelled]) {
[SVProgressHUD showErrorWithStatus:@"上传失败"];
[SVProgressHUD dismiss];
}
}];
}
ASIHttpRequest已经停止更新维护了，建议使用AF
最后我每使用ASIHttpRequest，用NSURLSessionDataTask建立链接发请求了。
//上传文件方法
