ios 上传txt格式log日志文件(文件上传)

ios上传log日志文件txt 最详细使用方法

保存本地

首先,我们可以先获取document文件的路径 ,    第一次创建的时候可以加个@"crash"的提示    然后就可以放我们想要存储的东西方了.

 NSString *documentPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
  NSString *fieldPath = [documentPath stringByAppendingPathComponent:@"logFiles.txt"];
  NSFileManager * manager = [NSFileManager defaultManager];
  if(![manager fileExistsAtPath:fieldPath]){
    NSString *str = @"crash:\n";
    [str writeToFile:fieldPath atomically:YES encoding:NSUTF8StringEncoding error:nil];
  }
  NSFileHandle *handle = [NSFileHandle fileHandleForUpdatingAtPath:fieldPath];
  //  准备要写入的字符串
  [handle seekToEndOfFile];
  NSData *data = [[NSString stringWithFormat:@"%@",errorInfoDic] dataUsingEncoding:NSUTF8StringEncoding];
  [handle writeData:data];
  [handle closeFile];

获取本地文件

在我们想要上传的地方  比如设置中某个按钮上传日志

NSString *documentPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
  NSFileHandle * srcFile;//  输入文件、输出文件
  NSData * buffer;//  读取的缓冲数据
  //    NSFileManager * manager = [NSFileManager defaultManager];
  NSString * sourcePath = [documentPath stringByAppendingPathComponent:@"logFiles.txt"];//  源文件路径
  //  覆盖数据
  //    [manager createFileAtPath:sourcePath contents:[@"Hello" dataUsingEncoding:NSUTF8StringEncoding] attributes:nil];
  srcFile = [NSFileHandle fileHandleForReadingAtPath:sourcePath];
  buffer = [srcFile readDataToEndOfFile];//  读取数据
  NSLog(@"%@",sourcePath);

上传log

根据需求把我们的logFiles.txt 上传给服务器,   代码中的logFile.txt 是我们给服务器的名字     logFiles.txt 是在本地存储的名字  不要弄混了

NSMutableDictionary * dic = [[NSMutableDictionary alloc] init];
  [dic setValue:SEEKPLISTTHING(USER_ID) forKey:@"userId"];
  [dic setValue:self.viewModel.configId forKey:@"configId"];
  
  NSString *endStr = [NSString stringWithFormat:@"%@mobileLog/upload",HTTP_LOOK_HOST];
  AFHTTPSessionManager *session = [AFHTTPSessionManager manager];
  NSString *encodeUrl =[NSString stringWithFormat:@"Bearer %@",[IF_NULL_TO_STRING(SEEKPLISTTHING(USER_TOKEN)) stringByURLEncode]];
  [session.requestSerializer setValue:encodeUrl forHTTPHeaderField:@"Authorization"];
  ShowHud();
  self.uploadTask =  [session POST:endStr parameters:dic constructingBodyWithBlock:^(id<AFMultipartFormData>  _Nonnull formData) {
    [formData appendPartWithFileData:buffer name:@"logFile" fileName:@"logFile.txt" mimeType:@"image/txt"];
  } progress:^(NSProgress * _Nonnull uploadProgress) {
    NSLog(@"%f",uploadProgress.fractionCompleted);
    //        process(uploadProgress.fractionCompleted,@"",@"");
    [uploadProgress addObserver:self forKeyPath:@"fractionCompleted" options:NSKeyValueObservingOptionNew context:nil];
  } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    HideHud();
    NSDictionary *resDic = responseObject;
    NSLog(@"txt日志查看地址-----%@",[resDic objectForKey:@"data"]);
    ShowTip([resDic objectForKey:@"msg"]);
  } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    HideHud();
  }];
  [self.uploadTask resume];

可以实现观察者方法，当progress对象的fractionCompleted属性值发生变化时回调此方法，在主线程中更新 UI

- (void)observeValueForKeyPath:(NSString *)keyPath
                  ofObject:(id)object
                    change:(NSDictionary<NSString *,id> *)change
                   context:(void *)context {

    NSProgress *progress = nil;
    if ([object isKindOfClass:[NSProgress class]]) {
        progress = (NSProgress *)object;
    }
    if (progress) {
        dispatch_async(dispatch_get_main_queue(), ^{
            // 在主线程中更新 UI
            self.progressHUD.progress = progress.fractionCompleted;
        });
    }
}
