Question

编辑：感谢您的建议。我更改了代码以实现json对象而不是字符串并在正文中发送

这就是我试图从调查猴子那里得到的细节。我得到的响应代码为200，但无法获得我需要的数据。有人可以让我知道我在做错了什么。可能是这个网址可以帮助指定我正在尝试做什么 https://developer.surveymonkey.com/mashery/requests_responses 这是o / p我得到{“status”：3，“errmsg”：“没有JSON对象可以被解码：第1行第0列（char 0）”}

Answer 1

POST正文的JSON编码无效。

您的代码String body=" '{\"fields\":[\"title\"]}'";

应为String body="{\"fields\":[\"title\"]}";

我建议在编码JSON对象时使用像json-simple这样的JSON库以避免无效的JSON。随着应用程序的发展，库也将更加灵活。

surveymonkey API调用返回状态代码3-无效请求
