ios监控
一.日志监控
I.自己写API调用
II.定义宏替换
#define NSLog(frmt,...) LogAPI(frmt,##__VA_ARGS__)
（##__VA_ARGS__可变参数宏，##去掉只有一个参数时的,号）
III.使用官方提供的框架
ASL apple system log （已弃用）ios(8.0,10.0)
NSLog：
Logs an error message to the Apple System Log facility.
IIII.fishhook
fishhook可以将我们Mach-O的库的符号表重新绑定
hook掉NSLog函数,这边采用这种方式
static void (* orig_nslog)(NSString *format, ...);
void redirect_nslog(NSString *format, ...) {
// 可以在这里先进行自己的处理
// 继续执行原 NSLog
orig_nslog(@"%@",[format stringByAppendingString:@"被HOOK了"]);
va_list va;
va_start(va, format);
NSLogv(format, va);
va_end(va);
}
- (void)openLogRecord
{
struct rebinding nsLog;
nsLog.name = "NSLog";
nsLog.replacement = redirect_nslog;
nsLog.replaced = (void *)&orig_nslog;
struct rebinding rebinds[1] = {nsLog};
rebind_symbols(rebinds, 1);
}
二.网络监控
I.NSURLProtocol
@class NSURLProtocol
@abstract NSURLProtocol is an abstract class which provides the
basic structure for performing protocol-specific loading of URL
data. Concrete subclasses handle the specifics associated with one
or more protocols or URL schemes.
抽象类，需要实现一个子类
+ (BOOL)canInitWithRequest:(NSURLRequest *)request
{
if ([NSURLProtocol propertyForKey:request.URL.absoluteString.md5String inRequest:request]) {
return NO;
}
NSString *url = request.URL.absoluteString;
// 如果url以https开头，则进行拦截处理，否则不处理
if ([url hasPrefix:@"https"] ||[url hasPrefix:@"http"]) {
return YES;
}
return NO;
}
/**
* 如果需要对请求进行重定向，添加指定头部等操作，可以在该方法中进行
*/
+ (NSURLRequest *)canonicalRequestForRequest:(NSURLRequest *)request {
NSMutableURLRequest *req = [request mutableCopy];
[NSURLProtocol setProperty:@(YES) forKey:request.URL.absoluteString.md5String inRequest:req];
return req;
}
II.WKURLSchemeHandler
调用wkwebview的方法setURLSchemeHandler:forURLScheme:
WKWebViewConfiguration *configuration = [[WKWebViewConfiguration alloc] init];
if (@available(iOS 11.0, *)) {
URLSchemeHandler *handler = [URLSchemeHandler new];
[configuration setURLSchemeHandler:handler forURLScheme:@"https"];
[configuration setURLSchemeHandler:handler forURLScheme:@"http"];
} else {
// Fallback on earlier versions
}
声明http，https需要拦截
直接拦截会导致崩溃，需要方法交换一下
+ (void)load {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
Method handlesURLScheme = class_getClassMethod(self, @selector(handlesURLScheme:));
Method ssshandlesURLScheme = class_getClassMethod(self, @selector(ssshandlesURLScheme:));
method_exchangeImplementations(handlesURLScheme, sshandlesURLScheme);
});
}
+ (BOOL)ssshandlesURLScheme:(NSString *)urlScheme {
if(DailyRecordManager.shared.type&DailyRecordAll ||
DailyRecordManager.shared.type&DailyRecordRequest
){
//返回NO,否则可能会中断言， 'http' is a URL scheme that WKWebView handles natively
if ([urlScheme isEqualToString:@"http"] || [urlScheme isEqualToString:@"https"]) {
return NO;
} else {
return [self ssshandlesURLScheme:urlScheme];
}
}else{
return [self ssshandlesURLScheme:urlScheme];
}
}
//对于NSURLSession发起的网络请求，我们发现通过shared得到的session发起的网络请求都能够监听到，但是通过方法sessionWithConfiguration:delegate:delegateQueue:得到的session，我们是不能监听到的，原因就出在NSURLSessionConfiguration上，我们进到NSURLSessionConfiguration里面看一下，他有一个属性 @property(nullable, copy)NSArray<Class>*protocolClasses;复制代码
//我们能够看出，这是一个NSURLProtocol数组，上面我们提到了，我们监控网络是通过注册NSURLProtocol来进行网络监控的，但是通过sessionWithConfiguration:delegate:delegateQueue:得到的session，他的configuration中已经有一个NSURLProtocol，所以他不会走我们的protocol来，怎么解决这个问题呢？ 其实很简单，我们将NSURLSessionConfiguration的属性protocolClasses的get方法hook掉，通过返回我们自己的protocol，这样，我们就能够监控到通过sessionWithConfiguration:delegate:delegateQueue:得到的session的网络请求
//https://juejin.cn/post/6844903473671077895
因为第三方sdk有可能对wkwebview有封装
所以直接hook掉wkwebview的configuration
+ (void)load {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
Method setConfiguration = class_getInstanceMethod(self, @selector(configuration));
Method setSSSConfiguration = class_getInstanceMethod(self, @selector(SSSConfiguration));
method_exchangeImplementations(setConfiguration, setSSSConfiguration);
Method con = class_getInstanceMethod(self, @selector(initWithFrame:configuration:));
Method ssscon = class_getInstanceMethod(self, @selector(sssinitWithFrame:configuration:));
method_exchangeImplementations(setConfiguration, setSSSConfiguration);
method_exchangeImplementations(con, ssscon);
});
}
III.查看NSURLSession的请求连接开始时间结束时间重定向次数等具体信息，iOS10之后可以使用代理方法，iOS10之前可以使用libcurl
-(void)URLSession:(NSURLSession *)session task:(NSURLSessionTask *)task didFinishCollectingMetrics:(NSURLSessionTaskMetrics *)metrics API_AVAILABLE(macosx(10.12), ios(10.0), watchos(3.0), tvos(10.0));

IIII.拦截console.log
使用js注入的方式
[configuration.userContentController addScriptMessageHandler:self name:@"logger"];//js打印事件
NSString *printContent = @"console.log = function(message){window.webkit.messageHandlers['logger'].postMessage(message)};";
WKUserScript *userScript = [[WKUserScript alloc] initWithSource:printContent injectionTime:WKUserScriptInjectionTimeAtDocumentEnd forMainFrameOnly:YES];
[configuration.userContentController addUserScript:userScript];

三.崩溃监控
NSSetUncaughtExceptionHandler();//设置崩溃时走的函数
NSGetUncaughtExceptionHandler();//获取崩溃处理函数
ios崩溃分类：
1.未捕获异常分类
2.底层信号崩溃
未捕获异常处理：
static NSUncaughtExceptionHandler *oldUncaughtExceptionHandler = nil;
void uncaughtExceptionHandler(NSException *exception) {
//记录日志等操作 旧崩溃函数处理
// Internal error reporting
}
oldUncaughtExceptionHandler = NSGetUncaughtExceptionHandler();
NSGetUncaughtExceptionHandler(&uncaughtExceptionHandler);//获取崩溃处理函数
底层信号崩溃
void SignalExceptionHandler(int signal){
NSLog(@"signal: %d", signal);
[DailyRecordManager.shared logType:(DailyRecordCrash) message:@(signal)];
}
- (void)crashSingleHandler{
signal(SIGABRT, SignalExceptionHandler);
signal(SIGILL, SignalExceptionHandler);
signal(SIGSEGV, SignalExceptionHandler);
signal(SIGFPE, SignalExceptionHandler);
signal(SIGBUS, SignalExceptionHandler);
}
