ios上传log日志文件txt 最详细使用方法

ios上传log日志文件txt

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  _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 *)change                  
context:(void*)context {
NSProgress*progress =nil;
if([object isKindOfClass:[NSProgressclass]]) {       
 progress = (NSProgress*)object;    
}
if(progress) {dispatch_async(dispatch_get_main_queue(), ^{
// 在主线程中更新 
UIself.progressHUD.progress = progress.fractionCompleted;      
  }
);   
 }}
