如何通过 selenium Chromedriver 禁用切割日志？

Question

我对从 selenium Chrome 驱动程序的控制台日志中捕获数据很感兴趣。线路可能会很长。这对我来说不是问题——无论如何我都需要完整的字符串。但是，线被切断了。有人知道如何禁止切割这些线吗？

来自 Chrome 控制台日志：

*07/29/2015 07:56:17,474 [1438145776486z8saqwcu9] [DEB] ["Request complete: https://some_server.addr.com:443/subarg1/subarg2/subarg3/subarg4/subarg5/login?_=5776213 Status: OK (200). **Response payload: ","NEXT_ACTION_12"]***

来自Chrome驱动程序日志：

*[29.240][DEBUG]: DEVTOOLS EVENT Console.messageAdded { "message": { "column": 24, "executionContextId": 10, "level": "debug", "line": 18849, "parameters": [ { "type": "string", "value": "07/29/2015 07:56:17,474 [1438145776486z8saqwcu9] [DEB] [\"Request complete: https://some_server.addr.com:443/subarg1/subarg2/subarg3/subarg4/subarg5/login?_=5776213 Status: OK (200). **Response payloa...**" } ], "source": "console-api",*

Answer 1

 ChromeDriverService.CreateDefaultService().LogPath = "1.txt";
 driver = new ChromeDriver();

在那种情况下，您应该捕获完整的字符串。

Answer 2

从我的角度来看，查看 chromedriver 源，这是不可能的。我看不到覆盖此行为的方法。截断由 chromedriver 本身进行。如果记录的值为字符串 - 它被截断为 200 个字符，请参阅下面的部分来源。 FormatValueForDisplay 正在为字符串值

调用 TruncateString

Status DevToolsClientImpl::ProcessEvent(const internal::InspectorEvent& event) {
  if (IsVLogOn(1)) {
    VLOG(1) << "DEVTOOLS EVENT " << event.method << " "
            << FormatValueForDisplay(*event.params);
  }

std::string FormatValueForDisplay(const base::Value& value) {
  scoped_ptr<base::Value> copy(SmartDeepCopy(&value));
  return PrettyPrintValue(*copy);
}

scoped_ptr<base::Value> SmartDeepCopy(const base::Value* value) {
//skipped code
} else if (value->GetAsString(&data)) {
    TruncateString(&data);
    return scoped_ptr<base::Value>(new base::StringValue(data));
  }

void TruncateString(std::string* data) {
  const size_t kMaxLength = 200;
  if (data->length() > kMaxLength) {
    data->resize(kMaxLength);
    data->replace(kMaxLength - 3, 3, "...");
  }
}
