我想从以下内容中检索JSON数据: https://git.eclipse.org/r/#/c/11376/
请求网址:https://git.eclipse.org/r/gerrit/rpc/ChangeDetailService
请求方法:POST
请求标题:
Accept:application/json
Content-Type:application/json; charset=UTF-8
请求有效负载:
{"jsonrpc":"2.0","method":"changeDetail","params":[{"id":11376}],"id":1}
我已经尝试了 this answer ,但我得到了400 BAD REQUEST
。
任何人都可以帮我解决这个问题吗?
感谢。

以下代码适用于我。
//escape the double quotes in json string
String payload="{\"jsonrpc\":\"2.0\",\"method\":\"changeDetail\",\"params\":[{\"id\":11376}],\"id\":2}";
String requestUrl="https://git.eclipse.org/r/gerrit/rpc/ChangeDetailService";
sendPostRequest(requestUrl, payload);
方法实施:
public static String sendPostRequest(String requestUrl, String payload) {
try {
URL url = new URL(requestUrl);
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setDoInput(true);
connection.setDoOutput(true);
connection.setRequestMethod("POST");
connection.setRequestProperty("Accept", "application/json");
connection.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream(), "UTF-8");
writer.write(payload);
writer.close();
BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
StringBuffer jsonString = new StringBuffer();
String line;
while ((line = br.readLine()) != null) {
jsonString.append(line);
}
br.close();
connection.disconnect();
return jsonString.toString();
} catch (Exception e) {
throw new RuntimeException(e.getMessage());
}
}

我尝试了一个休息客户。
标题:
它工作正常。我用一个好身体检索200 OK。
为什么在请求中设置状态代码? 使用Accept:application / json,application / json,application / jsonrequest进行多次声明“接受”。只是声明就足够了。
