仅在chrome开发工具中使用xhr请求创建har文件 [英] Create a har file with xhr request only in chrome dev tools

问题描述

是否只有在chrome开发工具中可以通过xhr请求创建har文件?

Is there a way to create a har file with xhr request only in chrome dev tools?

尽管我可以在开发工具中过滤请求，但是当我将其保存为har文件时，它包含所有请求.

Even though I can filter the requests in dev tools, when I save it as a har file, it contains all the requests.

如果dev devtools不支持该功能，是否还有其他方法可以实现?

If the dev devtools doesn't support that, is there a alternative way to do this?

推荐答案

似乎没有直接过滤请求的方法.我所做的就是创建包含所有请求的har文件并过滤该文件，然后在删除不需要的请求后再次保存它.

Seems like there is no direct way to filter the requests. What I did was, creating the har file with all the requests and filter that file, then save it again after removing unwanted requests.

在har文件内的内容中有一个名为entries的条目.它包含我们在数组中发送的所有请求.我得到了har文件的内容，并使用JSONPath表达式对其进行了过滤.

There is a entry called entries in the content inside har file. It contains all the requests we have sent in an array. I got the har file content and filtered it using JSONPath expressions.

关于JSONPath ，要过滤的表达式application/json类型:$..entries[?(@.response.content.mimeType == "application/json")]

Expression to filter application/json types : $..entries[?(@.response.content.mimeType == "application/json")]

之后，我将条目数组替换为在har文件中过滤的条目数组，然后再次保存.这样，您可以获取带有过滤的请求的har文件.使用相关的JSONPath表达式

After that I have replaced the entries array with the one I have filtered in the har file and saved it again. This way you can get a har file with filtered requests. Same way you can filter XHR or any other types using the relevant JSONPath expression
