我可以将内容长度标头注入Chrome吗？ [英] Can I inject a Content-Length header into Chrome?
问题描述
我正在尝试制作我的第一个Chrome扩展程序，这已经是一次颇具学习的体验。我几乎完成了，但这最后一块是杀了我。
我知道谷歌不希望你使用Content-Length（如这里），但我正在使用身份验证的API在POST时需要它。 此扩展说它可以做到，但我觉得我写的东西应该可以工作。这是最近在Chrome的新版本中被封锁的吗？
这些是我发送的头文件：
{
ReplaceHeaders：true，
rh-Authentication：< my auth token>，
rh-Timestamp：< ;时间戳>，
rh-Content-Length：body.length
}
这是将新的标题替换为rh标题的部分（除了rh-之外，所有内容都是rh-），如果这样做更合理的话。）：
chrome.webRequest.onBeforeSendHeaders.addListener（function（data）{
newHeaders = false;
_.find（data （header.name ===ReplaceHeaders）&&（header.value））{
_.find（data.requestHeaders，function（ h）{
if（h.name.substring（0，3）===rh-）{
if（newHeaders === false）{newHeaders = [];}
newHeaders.push（{
name：h.name.substring（3，h.name.length），
value：h.value
}）;
}
}）;
return;
}
}）;
if（!! newHeaders）{
//更新标题
return {requestHeaders：newHeaders};
}
}，{urls：[< all_urls>]}，[requestHeaders，blocking]）;
当我发出GET请求时，我没有rh-ContentLength标题，它起作用没问题（我可以看到SendHeaders，onHeadersReceived等）。一切都被替换，并且响应如预期。但是，当我使用rh-Content-Length发出POST请求时，我只能看到onSendHeaders，之后什么也没有。
我的onSendHeaders对于GET和POST都有新格式标题。
好的，所以我在凌晨3点发布。在得到一些急需的睡眠后，我今天早上醒来，并与一位朋友谈论此事。他指出，这个错误实际上是在我的ajax调用中。我解决了这个问题，现在我可以从我的扩展中发送Content-Length。上面的代码确实有效。
关于我之前发布的代码的一些注记，以供任何人稍后搜索： 尽管未经过测试，在其他标题，Chrome说它不会通过。以下是谷歌表示它在onBeforeSendHeaders中没有提供的头文件列表（如 here ）： 希望这有助于您。 I'm trying to make my first Chrome Extension and it has been quite a learning experience. I'm almost done, but this last piece is killing me. I know Google doesn't want you to use Content-Length (as stated here), but I'm working with an API who's authentication requires it when I POST. This extension says it can do it but I feel like what I wrote should work. Was this recently blocked in a new version of Chrome? These are the headers I am sending: This is the section that replaces the "rh" headers with the new headers (everything with "rh-", except for the "rh-" if that even makes sense.): When I make a GET request I don't have the "rh-ContentLength" header and it works fine (I can see onSendHeaders, onHeadersReceived, etc.). Everything is replaced and the response is as expected. But when I make a POST request with "rh-Content-Length" I only see onSendHeaders and nothing after that. My onSendHeaders for both GET and POST have the newly formatted headers. Ok, so I posted that at 3:00 AM. After getting some much needed sleep, I woke up this morning and talked to a friend about it. He pointed out that the mistake was actually in my ajax call. I fixed that and now I can send Content-Length from my extension. The above code does work. A few notes for the code I posted above for anybody searching for this later: Although not tested, this should work on other headers that Chrome says it won't pass. Here is a list of the headers Google says it doesn't provide in onBeforeSendHeaders (as documented here): Hope this helps. 这篇关于我可以将内容长度标头注入Chrome吗？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
