我在尝试向yelp API（v2）发出get请求时收到以下错误：
/**/cb({"error": {"text": "Signature was invalid", "id": "INVALID_SIGNATURE", "description": "Invalid signature. Expected signature base string:
GET\u0026http%3A%2F%2Fapi.yelp.com%2Fv2%2Fsearch\u0026_%3D1442688327244%26callback%3Dcb%26location%3DSan%252BFrancisco%26oauth_consumer_key%3DXI67kdnHbzVrvcY6jAfQKQ%26oauth_consumer_secret%3DWg3-20tFWx82F952ORa7ZIotsVE%26oauth_nonce%3DXQbTeX%26oauth_signature_method%3DHMAC-SHA1%26oauth_timestamp%3D1442688327%26oauth_token%3Dazu7S1QVuyIhn-LrHvBWIMR99OXceUyY%26term%3Dfood"}})
以下是我的要求：
http://api.yelp.com/v2/search?callback=cb&callback=cb&location=San%2BFrancisco&oauth_consumer_key=XI67kdnHbzVrvcY6jAfQKQ&oauth_consumer_secret=Wg3-20tFWx82F952ORa7ZIotsVE&oauth_signature_method=HMAC-SHA1&oauth_token=azu7S1QVuyIhn-LrHvBWIMR99OXceUyY&term=food&oauth_timestamp=1442688327&oauth_nonce=XQbTeX&oauth_signature=boKHi1X0rcUfcic8EgOVpXQHi4M%3D&_=1442688327244
如何解决此错误？谢谢:)）
答案 0 :(得分：0)
您添加callback=cb两次删除一个，网址应为字母顺序
http://api.yelp.com/v2/search?callback=cb&location=San%2BFrancisco&oauth_consumer_key=XI67kdnHbzVrvcY6jAfQKQ&oauth_consumer_secret=Wg3-20tFWx82F952ORa7ZIotsVE&oauth_nonce=XQbTeX&oauth_signature=boKHi1X0rcUfcic8EgOVpXQHi4M%3D&_=1442688327244&oauth_signature_method=HMAC-SHA1&oauth_timestamp=1442688327&oauth_token=azu7S1QVuyIhn-LrHvBWIMR99OXceUyY&term=food
