Fiddler:无法在

Question

我们使用Fiddler customRules.js脚本来处理我们的API测试(当其他公司没有测试服务器时来自它们的外部API)，其中如果有一个响应文件，我们会将一个响应文件发送回请求者，否则我们构建响应。这很好，但是我不能设置HTTP状态代码。

当我们生成响应时，在某些情况下，我们希望能够将HTTP状态指定为外部API可能发送的内容。

static function OnBeforeResponse(oSession: Session) {
    if (m_Hide304s && oSession.responseCode == 304) {
        oSession["ui-hide"] = "true";
    } 

    // Set Header values for later
    var HeaderContentType = 'text/xml;charset=utf-8';
    var HeaderServer = 'Apache-Coyote/1.1';
    var HttpStatus = 200;

    ...  // This is the removed code that determines text or file to return

    // At the end of our process to determine to send a file or error we try to send an error value in this case. For simplicity, I am just hard assigning it without using a variable as we normally would. 
    oSession.responseCode = 500;
    oSession.oResponse.headers.HTTPResponseCode = 500;
    oSession.oResponse.headers.HTTPResponseStatus = "500 SERVER ERROR";

    oSession.ResponseHeaders.SetStatus(500, 'Server Error');   // This also does not work

    // However this does work to add the file contents into the response when the file exists.
    var ResponseFile = new ActiveXObject("Scripting.FileSystemObject");
    if (ResponseFile.FileExists(ReturnFileName)) {
        oSession["x-replywithfile"] = ReturnFileName;

        // Error message returned as the ReturnBody was not populated and Response File not found
    } else {
        oSession.utilSetResponseBody(ErrorMessage);
    }

    return;
}

终于找到了。问题是，当使用oSession["x-replywithfile"]返回错误时，我经常返回一个文件。但是，这总是使状态成为200 OK，即使我试图在oSession["x-replywithfile"]设置之后更改状态。

oSession["x-replywithfile"] = ReturnFileName;
oSession.responseCode = 500;

这仍然将始终返回一个200 OK。

更改为下面的内容将有效。

var FileContents = ReadFile(ReturnFileName);
oSession.utilSetResponseBody(FileContents);
oSession.responseCode = 500;
