postman的一些使用方法

1.当请求体为json格式时，如何添加注释（xml的时候注释很方便，但是json汇报注释一并作为请求体发出）
在网上寻找到答案，利用请求前脚本去除掉json中注释的内容，实现无感处理。

//  去除json参数注释方法
GlobalJsonMinify = function (json) {
 
    var tokenizer = /"|(\/\*)|(\*\/)|(\/\/)|\n|\r|\[|]/g,
        in_string = false,
        in_multiline_comment = false,
        in_singleline_comment = false,
        tmp, tmp2, new_str = [], ns = 0, from = 0, lc, rc,
        prevFrom
    ;
 
    tokenizer.lastIndex = 0;
 
    while ( tmp = tokenizer.exec(json) ) {
        lc = RegExp.leftContext;
        rc = RegExp.rightContext;
        if (!in_multiline_comment && !in_singleline_comment) {
            tmp2 = lc.substring(from);
            if (!in_string) {
                tmp2 = tmp2.replace(/(\n|\r|\s)*/g,"");
            }
            new_str[ns++] = tmp2;
        }
        prevFrom = from;
        from = tokenizer.lastIndex;
 
        // found a " character, and we're not currently in
        // a comment? check for previous `\` escaping immediately
        // leftward adjacent to this match
        if (tmp[0] === "\"" && !in_multiline_comment && !in_singleline_comment) {
            // limit left-context matching to only go back
            // to the position of the last token match
            //
            // see: https://github.com/getify/JSON.minify/issues/64
            lc.lastIndex = prevFrom;
 
            // perform leftward adjacent escaping match
            tmp2 = lc.match(/(\\)*$/);
            // start of string with ", or unescaped " character found to end string?
            if (!in_string || !tmp2 || (tmp2[0].length % 2) === 0) {
                in_string = !in_string;
            }
            from--; // include " character in next catch
            rc = json.substring(from);
        }
        else if (tmp[0] === "/*" && !in_string && !in_multiline_comment && !in_singleline_comment) {
            in_multiline_comment = true;
        }
        else if (tmp[0] === "*/" && !in_string && in_multiline_comment && !in_singleline_comment) {
            in_multiline_comment = false;
        }
        else if (tmp[0] === "//" && !in_string && !in_multiline_comment && !in_singleline_comment) {
            in_singleline_comment = true;
        }
        else if ((tmp[0] === "\n" || tmp[0] === "\r") && !in_string && !in_multiline_comment && in_singleline_comment) {
            in_singleline_comment = false;
        }
        else if (!in_multiline_comment && !in_singleline_comment && !(/\n|\r|\s/.test(tmp[0]))) {
            new_str[ns++] = tmp[0];
        }
    }
    new_str[ns++] = rc;
    return new_str.join("");
};
