I think Amith Koujalgi is correct but also, in cases where the webservice responses are in JSON then it might be more useful to see the results in a clean JSON format instead of a very long string. Just add | grep }| python -mjson.tool to the end of curl commands here is two examples:
我认为 Amith Koujalgi 是正确的,但在 Web 服务响应是 JSON 的情况下,以干净的 JSON 格式而不是很长的字符串查看结果可能更有用。只需添加 | grep }| python -mjson.tool 到 curl 命令的末尾是两个例子:
GET approach with JSON result
使用 JSON 结果的 GET 方法
curl -i -H "Accept: application/json" http://someHostName/someEndpoint | grep }| python -mjson.tool
POST approach with JSON result
带有 JSON 结果的 POST 方法
curl -X POST -H "Accept: Application/json" -H "Content-Type: application/json" http://someHostName/someEndpoint -d '{"id":"IDVALUE","name":"Mike"}' | grep }| python -mjson.tool
