    "searchStatus": 0,
    "errMsg": "success",
    "checkResults": [{
        "versionName": "versionNameSample",
        "versionCode": "versionCodeSample",
        "verifyInfo": "verifyInfoSHA256Value1234567",
        "size": 1234567,
        "packageType": 1,
        "url": "http://serverAddressSample/packageNameSample.fileTypeSample",
