java实现get请求参数串转post请求(json字符串)

前一阶段，由于系统接口变更(由原get请求变更为post请求),导致对应接口的参数化数据需要进行处理。

注:post请求中,参数化数据需要使用json串。

如下图：

原get请求参数化信息：

S_CV_EDU_LEVEL=4&S_CURRENT_CAREER_STATUS=2&CompanyId=121111111&S_CV_JOB_LEVEL_ALL=16000100040000%3B16000100070000%3B16000100080000&ip=xx.xx.xx.xx&start=80&sort=complex_v17&rows=20&S_DISCLOSURE_LEVEL=2&S_EXCLUSIVE_COMPANY=%E6%B2%B3%E5%8C%97%E4%BA%92%E5%8A%A8%E5%BD%B1%E8%A7%86%E4%BC%A0%E5%AA%92%E6%9C%89%E9%99%90%E5%85%AC%E5%8F%B8%3B%E6%B2%B3%E5%8C%97%E4%BA%92%E5%8A%A8%E5%BD%B1%E8%A7%86%E4%BC%A0%E5%AA%92%E6%9C%89%E9%99%90%E5%85%AC%E5%8F%B8&S_CV_ACTIVE_TIME_LAST=1625209200%2C1632985200&S_WORK_YEARS=192210%2C202009&UserId=211111111&client=ihrsearch&DepartmentId=211111111&S_DESIRED_CITY=111

现post请求参数化信息：

{
    "parameter": {
        "S_CV_EDU_LEVEL": "4",
        "S_CURRENT_CAREER_STATUS": "2",
        "CompanyId": "121111111",
        "S_CV_JOB_LEVEL_ALL": "16000100040000%3B16000100070000%3B16000100080000",
        "ip": "xx.xx.xx.xx",
        "start": 80,
        "sort": "complex_v17",
        "rows": 20,
        "S_DISCLOSURE_LEVEL": "2",
        "S_EXCLUSIVE_COMPANY": "%E6%B2%B3%E5%8C%97%E4%BA%92%E5%8A%A8%E5%BD%B1%E8%A7%86%E4%BC%A0%E5%AA%92%E6%9C%89%E9%99%90%E5%85%AC%E5%8F%B8%3B%E6%B2%B3%E5%8C%97%E4%BA%92%E5%8A%A8%E5%BD%B1%E8%A7%86%E4%BC%A0%E5%AA%92%E6%9C%89%E9%99%90%E5%85%AC%E5%8F%B8",
        "S_CV_ACTIVE_TIME_LAST": "1625209200%2C1632985200",
        "S_WORK_YEARS": "192210%2C202009",
        "UserId": "211111111",
        "client": "ihrsearch",
        "DepartmentId": "211111111",
        "S_DESIRED_CITY": "111"
    }
}
