问题描述

在使用postman进行接口测试的时候，总是会碰到一个问题，请求参数如果是 json 格式时是不支持注释的，会将注释也一并发送出去，后端接受后可能会导致数据不正确。

解决方案

使用正则匹配的方法，利用Pre-request Script（前置脚本）预处理发送出去的JSON格式信息

添加方法

处理效果

预处理函数代码

方法代码如下：

//去除json参数中的注释信息
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;if (tmp[0] === "\"" && !in_multiline_comment && !in_singleline_comment) {lc.lastIndex = prevFrom;tmp2 = lc.match(/(\\)*$/);if (!in_string || !tmp2 || (tmp2[0].length % 2) === 0) {in_string = !in_string;}from--; 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("");
