问题 When interacting with an API used for building forms, I make an API call to get all the response values associated with my form. The API returns a deeply nested JSON object with all my form values. One of the many response objects looks like this: { "title":{ "plain":"Send Money" }, "fieldset":[ { "label":{ "plain":"Personal Info Section" }, "fieldset":[ { "field":[ { "label":{ "plain":"First Name" }, "value":{ "plain":"Bob" }, "id":"a_1" }, { "label":{ "plain":"Last Name" }, "value":{ "plain

问题 I have an application with a .NET c# middle tier and angular front end. I am calling an api which results in a long running process. In IE I captured a message saying net::ERR_CONNECTION_RESET. In Chrome, I'm seeing a failed status after 10 minutes. I looked in our log tables and event viewer. The process is running on the server without failure, but something is causing the api controller method to run multiple times, every 5 minutes. In my developer tools there is no network indicator that

问题 I'm trying to add a value to an enumerated type in postgreSQL-9.6, and am having trouble figuring out what I'm doing wrong. var tc = new NpgsqlCommand(@"ALTER TYPE attributeName ADD VALUE IF NOT EXISTS :a", conn); //tc.Parameters.Add(new NpgsqlParameter("a", NpgsqlDbType.Text)); //tc.Parameters[0].Value = "test"; tc.Parameters.AddWithValue("a", NpgsqlDbType.Text, "test"); tc.ExecuteNonQuery(); I tried both the commented out code and the current version, and both resulted in an exception.

问题 I am stuck with the installation of TPC-E EGen on Mac OS X (or Linux). I have downloaded the workload generator from TPC website : www.tpc.org/tpce/egen-download-request.asp but I failed to build it. When using the following command for building the utilities: cd Utilities/prj/GNUMake/ make I receive the following error: ../../prj/GNUMake/Makefile.EGenUtilities:136: ../../obj/DateTime.d: No such file or directory ../../prj/GNUMake/Makefile.EGenUtilities:136: ../../obj/EGenVersion.d: No such

问题 What is the best way to convert unixTimestamp to local time in the following scenario? I am using Pub/Sub Subscription to BigQuery Template. Dataflow fetches data in json format from PubSub, does the transformation, inserts into BigQuery Preferably, I want to use UDF for data transformation setup. (For simplicity,) Input data includes only unixTimestamp. Example: {"unixTimestamp": "1612325106000"} Bigquery table has 3 columns: unix_ts:INTEGER, iso_dt:DATETIME, local_dt:DATETIME where unix_ts

问题 I am using redis in a heavily multi-threaded java application and getting intermittent ClassCastException s. Reading through various discussions seemed to point out this might be because the Jedis connection instance getting shared between multiple threads (https://github.com/xetorthio/jedis/issues/359). The solution suggested is to use JedisPool which is thread-safe. I have configured redis through Spring redis support by using RedisTemplate. A thing to note is I am using multiple templates

问题 I have plotted some data with Python and tried to change the ticks with FuncFormatter . Now I want to change the segmentation into round numbers. I also want minor ticks in the same formation, in my case it would be a 1/x segmentation. I want the scaling to spread. The pictures will help you to imagine my issue. import numpy as np import matplotlib.pyplot as plt import matplotlib.ticker as tick x = np.array([805.92055,978.82006,564.88627,813.70311,605.73361,263.27184,169.40317]) y = np.array(

问题 I am trying to read every two lines of text, create a slide, and insert each line in the cells of a 2 by 1 table respectively using VBA code.

问题 I'm trying to define reusable enum types with json schema (input for phoenixnap/springmvc-raml-plugin). { "$schema": "http://json-schema.org/schema", "definitions": { "MyEnum": { "type": "object", "javaType": "foo.bar.MyEnum", "properties": { "Value": { "enum": [ "OPT_1", "OPT_2" ] } }, "required": ["Value"] } } } Is there a way to define the schema without the "Value" property and use the enum values directly? 回答1: schema definition with top level enum { "$schema": "http://json-schema.org
