Java 在Jersey REST服务中调用Google Geocode API导致内部错误

我在后端的jersey REST服务调用中尝试访问Google Geocode API时遇到问题。 当我这样做时，它会在服务器上导致一个内部HTTP 400错误 但是，通过浏览器或客户端调用直接调用地理编码API是可行的 此外，调用调用另一个jersey REST服务的jersey REST服务也可以工作 直接呼叫任何东西都有效。将一个jersey服务嵌套到另一个jersey服务中是可行的。但是在jersey服务中嵌套GoogleAPI调用失败了

呼叫定位服务（“A”）

定位服务：（“B”）

直接调用位置实用程序地理编码器（“C”）

调用谷歌地理编码API（“D”）的地理编码函数

调用样本测试中的调用（“E”）

在一次调用中调用两个测试服务端点（“F”）

调用测试函数中的调用：（“G”）

C-D成功 E-F-G成功了 A-B-D出现故障，并在服务器控制台上打印下面的stacktrace

更新：

当以下线路发生故障时，呼叫内呼叫测试（E-F-G）正常工作

WebTarget WebTarget=client.target（“http://localhost:8080/arenamaster-后端/api”）.path（“测试”）.path（“func3”）
替换为：
WebTarget WebTarget=client.target（“https://en.wikipedia.org/wiki/List_of_HTTP_status_codes");
阅读正文表明，谷歌地理编码API不接受非UTF-8字符编码。我不得不改变这一行来让它工作：

String request = "https://maps.googleapis.com/maps/api/geocode/json?address=" + new URLEncoder().encode(address_key, Charset.availableCharsets().get("UTF-8")) + "&key=" + API_key;
