在我的應(yīng)用程序中，我想使用Retrofit從服務(wù)器獲取一些數(shù)據(jù)。我寫了下面的代碼，但是當(dāng)運行應(yīng)用程序并調(diào)用 api 時顯示以下錯誤：E/socketLogResponse: Err : com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $請查看我上面的代碼并幫助我來自服務(wù)器的 API 響應(yīng)：{ "status": "ok", "time": 0.014972925186157227}ApiService 接口：@POST("api/log") Call<SocketPingResponse> getSocketPingLog(@Header("jwt") String jwt, @Body SocketPingBodySendData socketPingBodySendData);SocketPingResponse 類：public class SocketPingResponse { @SerializedName("status") @Expose private String status; @SerializedName("time") @Expose private Double time; public String getStatus() { return status; } public void setStatus(String status) { this.status = status; } public Double getTime() { return time; } public void setTime(Double time) { this.time = time; }}SocketPingBodySendData 類：public class SocketPingBodySendData { @SerializedName("auction_id") @Expose int auction_id; @SerializedName("data") @Expose List<SocketPingEntity> data; public int getAuction_id() { return auction_id; } public void setAuction_id(int auction_id) { this.auction_id = auction_id; } public List<SocketPingEntity> getData() { return data; } public void setData(List<SocketPingEntity> data) { this.data = data; }}

Retrofit 是類型安全庫。這意味著它只等待特定（預(yù)定義）類型的對象。如果服務(wù)器發(fā)送其他內(nèi)容 - 它會因錯誤而崩潰。這是你的情況。只需檢查原始服務(wù)器響應(yīng)，您就會發(fā)現(xiàn)有什么問題。

我認(rèn)為當(dāng)沒有數(shù)據(jù)返回時問題會返回字符串。后端通常會出現(xiàn)此類錯誤。這個錯誤以前發(fā)生在我身上。當(dāng)沒有數(shù)據(jù)可用時，您應(yīng)該檢查響應(yīng) json

嘗試更改您的 API 調(diào)用
從
@POST("api/log")
Call<SocketPingResponse> getSocketPingLog(@Header("jwt") String jwt, @Body SocketPingBodySendData socketPingBodySendData);
到
@POST("api/log")
Call<String> getSocketPingLog(@Header("jwt") String jwt, @Body SocketPingBodySendData socketPingBodySendData);
pingEntityList.addAll(socketPingDatabase.socketPingDao().getSocketPingEntityList());
SocketPingBodySendData pingBodySendData = new SocketPingBodySendData();
pingBodySendData.setAuction_id(auctionID);
pingBodySendData.setData(pingEntityList);
Toast.makeText(context, ""+pingEntityList.size(), Toast.LENGTH_SHORT).show();
Call<String> pingResponseCall = apis.getSocketPingLog(jwtToken, pingBodySendData);
pingResponseCall.enqueue(new Callback<String>() {
@Override
public void onResponse(Call<String> call, Response<String> response) {
if (response.body() != null) {
//Convert here your string response to Other POJO format
}
}
@Override
public void onFailure(Call<String> call, Throwable t) {
Log.e("socketLogResponse", "Err : " + t.toString());
}
});
