Provisional headers are shown？怎麼調試

Provisional headers are shown？怎麼調試

老外給了一個方法：

The way I found about the extension that was blocking my resource was through the net-internals tool in Chrome:

For Latest Versions of chrome

Type chrome://net-export/ in the address bar and hit enter.
Start Recording. And save Recording file to local.
Open the page that is showing problems.
Go back to net-internals
You can view Recorded Log file Here https://netlog-viewer.appspot...
click on events (###) and use the textfield to find the event related to your resource (use parts of the URL).
Finally, click on the event and see if the info shown tells you something.

For Older Versions of chrome

Type chrome://net-internals in the address bar and hit enter.
Open the page that is showing problems.
Go back to net-internals, click on events (###) and use the textfield to find the event related to your resource (use parts of the URL).
Finally, click on the event and see if the info shown tells you something.
翻譯下

一、 打開chrome://net-export/

1. 點擊start log to disk， 會彈出個框，選擇存儲在本地位置
2. 在瀏覽器上操做，復現你的問題
3. 回到剛纔那個頁面，點擊 stop logging
4. 而後打開這個地址： https://netlog-viewer.appspot... 點擊選擇文件，導入剛纔導出的日誌記錄
5. 選擇Events，搜索下你的接口，能夠看右邊的日誌，其實是有cookie的。

其餘

還有個常常用的地址：chrome://net-internals

能夠用來清除DNS緩存這些
