Question

有一段时间我一直试图改变我的ACRA后端以包含问题ID，因此每个问题都不会显示为单个问题，但会显示为报告计数的一个问题。因此，我解决了这个问题：

// Finds in array
function array_find($needle, $haystack) {
    foreach($haystack as $k => $v) {
        if (strstr($v, $needle) !== FALSE) {
            return $k;
        }
    }
    return FALSE;
}
function bicou_short_stack_trace($stack_trace, $package) {
    $lines = explode("\n", $stack_trace);
    if (array_find(": ", $lines) === FALSE && array_find($package, $lines) === FALSE) {
        $value = $lines[0];
    } else {
        $value = "";
        foreach ($lines as $id => $line) {
        if (/*strpos($line, ": ") !== FALSE || */strpos($line, $package) !== FALSE
             || strpos($line, "Error") !== FALSE || strpos($line, "ACRA caught a") !== FALSE) {
                $value .= $line . "<br />";
            }
        }
    }
    return $value;
}

function bicou_issue_id($stack_trace, $package) {
    return md5(bicou_short_stack_trace($stack_trace, $package));
}

这应该采用堆栈跟踪和包并将其转换为问题ID，无论何时报告，都可以反复使用相同问题。所以我在我的应用程序中导致错误传输：

PHONE_MODEL = SM-G925F
ANDROID_VERSION = 6.0.1

每次都是完全相同的，除了每行前面定义的时间。

对于问题：每次输入完全相同，但每次都会产生不同的ID。我引起了3次，这里是ID：

69b30e6cff3768ff3e3616d85a4b2ea8
e2c090b737a4e854106c373fa408779c
038e70fe97be4e23cac2d6bb42df751c

堆栈跟踪不包含在.txt文件的前两行和后两行中。

我该如何解决这个问题？它真的很烦人，因为上面的代码需要很长时间才能解决它并且不起作用。

要求：

如果stacktrace相同，我希望输出（ID）相同，但它似乎不起作用。

修改

感谢Samurai8，我设法得到了这个：

$reworkedLog = $LOG;
$reworkedLog = str_replace('LOGCAT =', '', $reworkedLog);

$reworkedLog = preg_replace("'\d{2}-\d{2} \d{2}:\d{2}:\d{2}\.\d*'", '', $reworkedLog);
$reworkedLog = preg_replace("'$\d*'", '', $reworkedLog);
$reworkedLog = preg_replace("'0x[0-9a-f]*'", '', $reworkedLog);
$reworkedLog = preg_replace("'(\d{5})'",'', $reworkedLog);
$reworkedLog = preg_replace("'... \d{1} more'", '', $reworkedLog);
$reworkedLog = preg_replace("'... \d{2} more'", '', $reworkedLog);

$issue_id = bicou_issue_id($reworkedLog, $package) . '<br>';

这使得错误md5每次都相同

Answer 1

你应该牢记三件事：

md5是一个哈希函数。这意味着许多输入具有相同的输出。永远不能保证两个完全不同的堆栈跟踪会产生不同的ID。这意味着即使id已经在系统中，也不能盲目地忽略堆栈跟踪。
输入的微小差异将导致不同的哈希值。向堆栈跟踪添加单个空格或更改单个字符将导致生成不同的哈希，从而为您提供不同的ID。
堆栈跟踪通常包含执行的日期和时间代码，对象的内存位置和实例化编号。在您的情况下，您的logcat包含所有这些：
```
07-14 15:51:20.891
```
和
```
eglInitialize EGLDisplay = 0x7f97440178
```
和
```
at android.app.ActivityThread.access$1100
```
堆栈跟踪本身只包含日期和实例化编号，但足以创建不同的ID。

你能做什么？我们可以从生成id的堆栈跟踪中剥离它们。我们可能希望将它们留在实际的堆栈跟踪中，因为它提供了一些上下文。只需preg_replace(..)使用以下正则表达式：

\d{2}-\d{2} \d{2}:\d{2}:\d{2}\.\d*日期和时间
\$\d*匿名课程
0x[0-9a-f]*表示十六进制值，可能是每次运行都会更改的内存位置。

当然这会增加id不唯一的机会，但我们已经确定你必须记录每个错误。给出相同内容的机会应该是最小的，但要确保无论你在哪里记录这些错误，都可以拆分错误报告，以防两个不同的错误记录在相同的id下。或者，为每个崩溃报告使用唯一ID，并根据计算出的ID自动建议重复。

根据两个参数为问题创建ID
