简介
本篇文章主要目的是为了将用户操作习惯记录到本地文件，然后定期或者根据实际需要打包压缩上传到服务器，用以处理用户在闪退的时候，或需要详细了解具体某个用户在这一段时间的操作习惯。由于要压缩上传本地日志，顺道集成了AFNetWorking了post和get的接口请求，以及请求是接口失败后，错误信息显示，这个在开发的时候特别方便，后台可以在根据这些错误日志查询对应的问题。

一、日志记录集成[LogManager]
在文件中，对每个方法和属性都做了注释；有写入日志方法，也有打印写入日志的方法，以便于检查日志是否成功

// 跳到文件末尾 [fileHandler seekToEndOfFile]; // 追加数据 [fileHandler writeData:writeData]; // 关闭文件 [fileHandler closeFile]; } } @end
打印记录日志的页面：
#import <UIKit/UIKit.h> @interface ZMLogView : UIView ///初始化 +(instancetype)initLogView; ///打印日志信息 -(void)logInfo:(NSString *)str; @end
#import "ZMLogView.h" //大小尺寸 #define kLogViewFrame CGRectMake(0, 0, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height) @interface ZMLogView() ///标签 @property(nonatomic,strong)UITextView *textView; ///标题 @property(nonatomic,strong)UILabel *titleLbl; @end @implementation ZMLogView{ CGRect _frame; } #pragma mark - 赋值 -(void)logInfo:(NSString *)str{ if (str) { self.textView.text = str; }else{ self.textView.text = @"暂无日志信息"; } } #pragma mark -Methods #pragma mark - Intial +(instancetype)initLogView{ return [[self alloc]initWithFrame:CGRectZero]; } -(instancetype)initWithCoder:(NSCoder *)aDecoder{ if (self = [super initWithCoder: aDecoder]) { self.frame = kLogViewFrame; [self setUpBaseData]; [self setUpUI]; } return self; } -(instancetype)initWithFrame:(CGRect)frame{ frame = kLogViewFrame; if (self = [super initWithFrame:frame]) { [self setUpBaseData]; [self setUpUI]; } return self; } ///基本数据配置 -(void)setUpBaseData{ } ///控件添加 -(void)setUpUI{ [self textView]; } #pragma mark - 布局 -(void)layoutSubviews{ [super layoutSubviews]; } #pragma mark - lazyload -(UILabel *)titleLbl{ if (!_titleLbl) { _titleLbl = [UILabel new]; _titleLbl.frame = CGRectMake(10, 20, [UIScreen mainScreen].bounds.size.width - 20, 20); _titleLbl.textAlignment = NSTextAlignmentCenter; _titleLbl.textColor = [UIColor purpleColor]; if (@available(iOS 8.2, *)) { _titleLbl.font = [UIFont systemFontOfSize:18 weight:1]; } else { _titleLbl.font = [UIFont systemFontOfSize:18]; } _titleLbl.text = @"打印日志"; [self addSubview:_titleLbl]; } return _titleLbl; } -(UITextView *)textView{ if (!_textView) { _textView = [UITextView new]; _textView.font = [UIFont systemFontOfSize:14]; _textView.textColor = [UIColor darkGrayColor]; CGRect frame = CGRectMake(10, CGRectGetMaxY(self.titleLbl.frame),[UIScreen mainScreen].bounds.size.width - 20, [UIScreen mainScreen].bounds.size.height - 50); _textView.frame = frame; _textView.showsHorizontalScrollIndicator = NO; [_textView setEditable:NO]; [self addSubview:_textView]; } return _textView; } -(void)dealloc{ } @end
打印日志应用实例,在还没引入上传请求接口时，【LogManager.m】文件中可以先将请求接口其注释避免报错：
#import "LogManager.h" #import "ZMLogView.h" ///显示日志 @property(nonatomic,strong)ZMLogView *logView; - (void)viewDidLoad { [super viewDidLoad]; [self testForLocalLog]; } ///写入数据到本地文件并显示 -(void)testForLocalLog{ //写入数据到本地文件 LLog(@"错误信息",@"五哦粗"); //获取日志信息并显示 NSString *str = [[LogManager sharedInstance] readFile:@"2018-09-11"]; NSLog(@"%@",str); //渲染 [self.logView logInfo:str]; } #pragma mark - lazyload -(ZMLogView *)logView{ if (!_logView) { _logView = [ZMLogView initLogView]; [self.view addSubview:_logView]; } return _logView; }
二、使用【AFNetworking】集成接口
1、get请求
/** get请求 @param url 链接 @param params 参数 @param success 成功代码块 @param failure 失败代码块 */ - (void)base_GetWithUrl:(NSString *)url parameters:(NSDictionary *)params success:(void(^)(id success))success failure:(void(^)(id failure))failure{ url = [NSString stringWithFormat:@"%@%@",kURLMain,url]; // 创建请求对象 AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; manager.requestSerializer = [AFHTTPRequestSerializer serializer]; //设置请求数据 manager.responseSerializer = [AFHTTPResponseSerializer serializer];//设置返回数据 //请求头设置 [ZMBaseEngine setHttpHeaderWithManager:manager]; // 设置超时时长 manager.requestSerializer.timeoutInterval = 10.0f; //NSString *strUrl = [NSString stringWithFormat:@"%@%@",kURLMain,url]; [manager GET:url parameters:params progress:^(NSProgress * _Nonnull downloadProgress) { } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { //json解析 NSDictionary *dic = [self jsonToDic:responseObject]; success(dic); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { [self handlingError:error failure:failure]; }]; }
2、Post请求
/** post请求 @param url 链接 @param params 参数 @param success 成功代码块 @param failure 失败代码块 */ - (void)base_PostWithUrl:(NSString *)url parameters:(id)params success:(void(^)(id success))success failure:(void(^)(id failure))failure{ url = [NSString stringWithFormat:@"%@%@",kURLMain,url]; // 创建请求对象 AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; manager.requestSerializer = [AFHTTPRequestSerializer serializer]; //设置请求数据 manager.responseSerializer = [AFHTTPResponseSerializer serializer];//设置返回数据 //请求头设置 [ZMBaseEngine setHttpHeaderWithManager:manager]; // 设置超时时长 manager.requestSerializer.timeoutInterval = 10.0f; [manager POST:url parameters:params progress:^(NSProgress * _Nonnull uploadProgress) { } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { //json解析 NSDictionary *dic = [self jsonToDic:responseObject]; success(dic); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { [self handlingError:error failure:failure]; }]; }
3、图片上传
/** 图片上传 @param imgData 图片data @param fileName 图片名称 @param type 类型 @param url 链接 @param params 参数 @param progress 进度代码块 @param success 成功代码块 @param failure 失败代码块 */ - (void)base_UpLoadImage:(NSData *)imgData fileName:(NSString *)fileName imgType:(NSString *)type PostWithURL:(NSString *)url parameters:(id)params progress:(void(^)(id progress))progress success:(void(^)(id success))success failure:(void(^)(id failure))failure{ url = [NSString stringWithFormat:@"%@%@",kURLMain,url]; AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; // 设置超时时长 manager.requestSerializer.timeoutInterval = 30.0f; manager.requestSerializer = [AFJSONRequestSerializer serializer]; manager.responseSerializer =[AFHTTPResponseSerializer serializer]; manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/html",@"image/png",@"image/jpeg",nil]; [manager POST:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) { //上传数据，域名为fileName [formData appendPartWithFileData:imgData name:@"imageFile"fileName:fileName mimeType:[NSString stringWithFormat:@"image/%@",type]]; } progress:^(NSProgress * _Nonnull uploadProgress) { progress(uploadProgress); } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { //json解析 NSDictionary *dic = [self jsonToDic:responseObject]; success(dic); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { [self handlingError:error failure:failure]; }]; }
4、文件上传
/** 上传文件 @param url 链接 @param params 参数 @param fileName 文件名 @param upName 上传文件名 @param filePath 路径 @param progress 进度代码块 @param success 成功代码块 @param failure 失败代码块 */ - (void)base_UpdateFileWithUrl:(NSString*)url parameters:(NSMutableDictionary*)params fileName:(NSString*)fileName upName:(NSString *)upName filePath:(NSString *)filePath progress:(void(^)(id progress))progress success:(void(^)(id success))success failure:(void(^)(id failure))failure{ url = [NSString stringWithFormat:@"%@%@",kURLMain,url]; if (!upName) { upName = fileName; } AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; //请求头设置 [ZMBaseEngine setHttpHeaderWithManager:manager]; [manager POST:url parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) { /* 第一个参数:文件的URL路径 第二个参数:参数名称 file 第三个参数:在服务器上的名称 第四个参数:文件的类型 */ if (filePath&&fileName) { NSData*fileData = [NSData dataWithContentsOfFile:filePath]; // [formData appendPartWithFileURL:[NSURL fileURLWithPath:@""] name:fileName error:nil]; [formData appendPartWithFileData:fileData name:upName fileName:fileName mimeType:@"application/zip"]; } } progress:^(NSProgress * _Nonnull uploadProgress) { progress(uploadProgress); } success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { //json解析 NSDictionary *dic = [self jsonToDic:responseObject]; success(dic); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { [self handlingError:error failure:failure]; }]; }
5、请求头/错误处理
///接口请求头 +(void)setHttpHeaderWithManager:(AFHTTPSessionManager *)manager{ manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript",@"text/html", nil]; #pragma mark --- 请求头的设置自Header //app应用相关信息的获取 NSDictionary *dicInfo = [[NSBundle mainBundle] infoDictionary]; //App版本 NSString *strAppVersion = [dicInfo objectForKey:@"CFBundleShortVersionString"]; //系统名称 NSString *strSysName =[[UIDevice currentDevice]systemName];

//设备的平台 [manager.requestSerializer setValue:strSysName forHTTPHeaderField:@"platform"]; //设备的型号(模式) [manager.requestSerializer setValue:[NSString stringWithFormat:@"model:%@\t locModel:%@",strModel,strLocModel] forHTTPHeaderField:@"type"]; //系统版本 [manager.requestSerializer setValue:strSysVersion forHTTPHeaderField:@"sysVersion"]; //App的版本 [manager.requestSerializer setValue:strAppVersion forHTTPHeaderField:@"appVersion"]; // --------- other test ----------- [manager.requestSerializer setValue:@"19644" forHTTPHeaderField:@"MEMBERID"];

NSString *lastStr = arr.lastObject; NSString *errCodeStr; if ([self engineValidateStr:lastStr belongToStr:@"()1234567890."]) { errCodeStr = [lastStr substringWithRange:NSMakeRange(1, lastStr.length - 2)]?:@""; }else{ errCodeStr = lastStr; } //打印错误信息 NSString *dataStr = nil; if (data.length > 0) { dataStr = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding]; }else{ dataStr = @"错误日志为空"; } NSString *errorResponse = error.userInfo[@"com.alamofire.serialization.response.error.response"]; NSString *errorUrl = error.userInfo[@"NSErrorFailingURLKey"]; NSString *errorStr = [NSString stringWithFormat:@"--------- 开始 --------<br><br>NSErrorFailingURLKey：<br>%@<br><br>NSLocalizedDescription：<br>%@<br><br>com.alamofire.serialization.response.error.response：<br>%@<br><br>com.alamofire.serialization.response.error.data:<br>%@<br><br>--------- 结束 --------",errorUrl,errDesStr,errorResponse,dataStr];

} else { result = window.rootViewController; } return result; }
三、错误h5集成
在请求接口报错时，会直接调用该类方法
#import <UIKit/UIKit.h> #import <WebKit/WebKit.h> @interface ZMWKWebViewVC : UIViewController @property (nonatomic, strong) WKWebView *wkWebView; -(void)zm_WKLoadUrl:(NSString *)url; @end
