如何在Fiddler Script中自定义修改请求参数

//根据host判断
if(oSession.host=="www.baidu.com"){
    oSession.RequestHeaders.Remove("User-Agent");
    oSession.RequestHeaders.Add("User-Agent","Dalvik/2.1.0 (Linux; U; Android 9.0.1; onePlus666 Build/MOB31K)");
}

//请求拦截
var isTelecomAuth: boolean = false;
if(oSession.host == ‘www.xxxxxx.com‘ && oSession.url.Contains("/api/")){
    isTelecomAuth = oSession.url.Contains("/api/web/telecom/getTel");
    isTelecomAuth = isTelecomAuth || oSession.url.Contains("/api/web/telecom/addAuthRecord");
    
    //如果不是运营商授信，进行拦截
    if(!isTelecomAuth){
        oSession.host = ‘api.xxxxx.com‘;
        oSession.url =  oSession.url.Replace("/api/", "/");   
    }
}

if(oSession.host == ‘www.xxxx.com‘ && oSession.url.Contains("/api/xxx")){
    //更改后的JSON数据
    var mylogin=‘{"uids":[200005445],"card_type":1,"cmd":"2124525","token":"26fed74802233c112bb7e9fcb97a11ac"}‘;
    var requestJson=Fiddler.WebFormats.JSON.JsonDecode(mylogin);
    var reJsonDes=Fiddler.WebFormats.JSON.JsonEncode(requestJson.JSONObject);
    oSession.utilSetRequestBody(reJsonDes);
    
    //替换字符串
    //var strBody = oSession.GetRequestBodyAsString();
    //oSession.utilSetRequestBody(strBody.Replace("com.jyblife.risk.profile.service.AuthStateService","com.jyblife.risk.profile.service.AuthStateService"));
    
    //打印修改后的内容
    //MessageBox.Show(oSession.GetRequestBodyAsString());
