但搜索结果将不会显示。我在控制台中列出了以下错误
ERROR - SynapseJsonPath #stringValueOf. Error evaluating JSON Path <$.apiKey>. Returning empty result. Error>>> invalid path

但如果我像这样将GoogleAPI密钥直接放在init文件的配置中,我可以得到预期的结果
<http method="get" uri-template="https://www.googleapis.com/customsearch/v1?q={uri.var.searchQuery}&key=XXXXXXXXXXXXXXXXXXX&cx=XXXXXXXXXXXXXXXX"/>
有什么问题吗?看来您在JSON路径上有错误,请更改
<googleCustomSearch.listSearch>
到
试试看。使用下面列出的博客获取更多信息
JSON请求无效。你错过了“,”
{
“apiKey”:“XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX”,
“csiKey”:“XXXXXXXXXXXXXXXXXXXXXXXXXXXX”,
“searchPara”:“谷歌”
}
即使我更改了路径,我也收到了以下错误消息:{error:{errors:[1]0:{domain:“usageLimits”原因:“keyInvalid”消息:“Bad Request”}代码:400消息:“Bad Request”}因此它包含了您的错误..keyInvalid。。尝试使用其他一些应用程序帐户凭据
