java - foursquare 多请求收到 400 错误请求

Question

我正在对 foursquare api 调用多重请求，如下所示:

 https://api.foursquare.com/v2/multi?%2Fvenues%2Fsearch%3Fll%3D33.859868%2C-117.886133%26query%3DTarget,%2Fvenues%2Fsearch%3Fll%3D33.859868%2C-117.886133%26query%3DNordstrom&intent=browse&radius=16093&oauth_token=WS10PQFRUXACDDIJMN3JEEIHFOPA1UTMRZP0E41MWAF0HHJL&v=20130419

oAuth token 是向公众开放的通用 token

我使用以下 java 代码创建 url:

 String baseUrl  = "https://api.foursquare.com/v2";
    String action = "/multi?";
    String request1 = "/venues/search?ll=33.859868,-117.886133&query=Target";
    String requestEnc1 = URLEncoder.encode(request1);
    String request2 = "/venues/search?ll=33.859868,-117.886133&query=Nordstrom";
    String requestEnc2 = URLEncoder.encode(request2);
    String commonParams = "&intent=browse&radius=16093&oauth_token=WS10PQFRUXACDDIJMN3JEEIHFOPA1UTMRZP0E41MWAF0HHJL&v=20130419";

我收到 400 错误请求。不过，这看起来与此处文档中的示例类似:

url的构造方式有问题吗？

Answer 1

如果您在浏览器中打开该 URL，您可以看到从 Foursquare 返回的错误消息是 errorDetail: "Must Provide parameter requests"。您没有正确构建调用:https://developer.foursquare.com/docs/multi/multi
