我在Unity内部使用Uber API,我可以登录然后进行身份验证以获取令牌,但是在调用实际API时遇到了障碍。
我认为我的问题是我需要以JSON格式拨打电话,但我不知道该怎么做。我是HTTP和API的新手。这是我的代码:
private IEnumerator TestRequest(){
Debug.Log(sToken);
WWWForm form = new WWWForm();
//WWW www = new WWW();
form.headers["Content-Type"] = "application.json";
form.headers["Authorization"] = "Bearer " +sToken;
form.AddField( "fare_id", "abcd");
form.AddField("product_id", "a1111c8c-c720-46c3-8534-2fcdd730040d");
form.AddField("start_latitude", "37.761492");
form.AddField("start_longitude", "-122.42394");
form.AddField("end_latitude", "37.775393");
form.AddField("end_longitude", "-122.417546");
yield return null;
using(UnityWebRequest uweb = UnityWebRequest.Post("https://sandbox-
api.uber.com/v1.2/requests", form)){
yield return uweb.Send();
if(uweb.isError) Debug.Log(uweb.error);
else Debug.Log(uweb.downloadHandler.text);
//GetVals(uweb.downloadHandler.text);
}
}
这在我的其他方面适用,但不适用于此,我认为它与内容类型为JSON有关,但我无法弄清楚如何以正确的格式发送它。抱歉,我可以更具体,我只是想了解这些事情。
非常感谢任何帮助!

与其他人一样,application.json
应为application/json
。
这是不唯一的问题。由于它是json,因此您不需要使用WWWForm
类。创建一个类来保存Json数据,然后创建它的新实例。将实例转换为json并将其传递给UnityWebRequest
Post函数的第二个参数。
<强> UnityWebRequest 强>:
对于UnityWebRequest
,请使用UnityWebRequest Post(string uri, string postData);
重载,以便传递网址和json数据。然后使用SetRequestHeader
设置标头。
[Serializable]
public class UberJson
{
public string fare_id;
public string product_id;
public double start_latitude;
public double start_longitude;
public double end_latitude;
public double end_longitude;
}
void Start()
{
postJson();
}
string createUberJson()
{
UberJson uberJson = new UberJson();
uberJson.fare_id = "abcd";
uberJson.product_id = "a1111c8c-c720-46c3-8534-2fcdd730040d";
uberJson.start_latitude = 37.761492f;
uberJson.start_longitude = -122.42394f;
uberJson.end_latitude = 37.775393f;
uberJson.end_longitude = -122.417546f;
//Convert to Json
return JsonUtility.ToJson(uberJson);
}
void postJson()
{
string URL = "https://sandbox-api.uber.com/v1.2/requests";
//string json = "{ \"fare_id\": \"abcd\", \"product_id\": \"a1111c8c-c720-46c3-8534-2fcdd730040d\", \"start_latitude\": 37.761492, \"start_longitude\": -122.423941, \"end_latitude\": 37.775393, \"end_longitude\": -122.417546 }";
string json = createUberJson();
string sToken = "";
//Set the Headers
UnityWebRequest uwrq = UnityWebRequest.Post(URL, json);
uwrq.SetRequestHeader("Content-Type", "application/json");
uwrq.SetRequestHeader("Authorization", "Bearer " + sToken);
StartCoroutine(WaitForRequest(uwrq));
}
IEnumerator WaitForRequest(UnityWebRequest uwrq)
{
//Make the request
yield return uwrq.Send();
if (String.IsNullOrEmpty(null))
{
Debug.Log(uwrq.downloadHandler.text);
}
else
{
Debug.Log("Error while rececing: " + uwrq.error);
}
}
如果UnityWebRequest
无效,请使用WWW
。有报告称有UnityWebRequest
的错误,但我个人没遇到过。
<强> WWW:强>
对于WWW
,使用public WWW(string url, byte[] postData, Dictionary<string, string> headers);
构造函数重载,它在一个函数调用中接收url,数据和标题。
[Serializable]
public class UberJson
{
public string fare_id;
public string product_id;
public double start_latitude;
public double start_longitude;
public double end_latitude;
public double end_longitude;
}
void Start()
{
postJson();
}
string createUberJson()
{
UberJson uberJson = new UberJson();
uberJson.fare_id = "abcd";
uberJson.product_id = "a1111c8c-c720-46c3-8534-2fcdd730040d";
uberJson.start_latitude = 37.761492f;
uberJson.start_longitude = -122.42394f;
uberJson.end_latitude = 37.775393f;
uberJson.end_longitude = -122.417546f;
//Convert to Json
return JsonUtility.ToJson(uberJson);
}
void postJson()
{
string URL = "https://sandbox-api.uber.com/v1.2/requests";
//string json = "{ \"fare_id\": \"abcd\", \"product_id\": \"a1111c8c-c720-46c3-8534-2fcdd730040d\", \"start_latitude\": 37.761492, \"start_longitude\": -122.423941, \"end_latitude\": 37.775393, \"end_longitude\": -122.417546 }";
string json = createUberJson();
string sToken = "";
//Set the Headers
Dictionary<string, string> headers = new Dictionary<string, string>();
headers.Add("Content-Type", "application/json");
headers.Add("Authorization", "Bearer " + sToken);
//headers.Add("Content-Length", json.Length.ToString());
//Encode the JSON string into a bytes
byte[] postData = System.Text.Encoding.UTF8.GetBytes(json);
WWW www = new WWW(URL, postData, headers);
StartCoroutine(WaitForRequest(www));
}
IEnumerator WaitForRequest(WWW www)
{
yield return www;
if (String.IsNullOrEmpty(null))
{
Debug.Log(www.text);
}
else
{
Debug.Log("Error while rececing: " + www.error);
}
