@sirfengyu 可否将原始的HAR文件发来看下？

重新看了下HAR的标准规范，是我理解错了，这里的确是有个bug。

"postData": {
    "mimeType": "multipart/form-data",
    "params": [],
    "text" : "plain posted data",
    "comment": ""
}
mimeType [string] - Mime type of posted data.
params [array] - List of posted parameters (in case of URL encoded parameters).
text [string] - Plain text posted data
comment [string, optional] (new in 1.2) - A comment provided by the user or the application.

Note that text and params fields are mutually exclusive.

有些请求类型的postData中是text，有些是params，并且两者互斥。
之前只考虑了text这种情况，而你的案例中用的是params，我修复下吧。

@sirfengyu 我刚修复了下，你升级到最新版再试下。

还是同样的har文件：报如下错误

@sirfengyu 修复了，问题在于你测试系统的Content-Type为application/jose，这种情况之前是没有兼容的。现在已经好了。
