json

问题 I've using Laravel, loading a db row into an Eloquent object. One of the columns is longtext, a JSON encoded array > 2 million characters long. The original error I was getting was json_decode failing on this column's value. I tested in tinker. Simplified test code: $item = Item::find(1); echo $item->long_text_field; var_dump(json_decode($item->long_text_field)); echo strlen($item->long_text_field); On my local vagrant instance this shows the correct values. ...long json array in text, same

问题 Scrapy seems to be pulling the data out correctly, but is formatting the output in my JSON object as if it were an array: [{"price": ["$34"], "link": ["/product/product..."], "name": ["productname"]}, {"price": ["$37"], "link": ["/product/product"]... My spider class looks like this: def parse(self, response): sel = Selector(response) items = sel.select('//div/ul[@class="product"]') skateboards = [] for item in items: skateboard = SkateboardItem() skateboard['name'] = item.xpath('li[@class=

问题 Instances of this class are part of a large object graph and are not at the root of the object graph: public class Day { public Day(LocalDate date, List<LocalTime> times) { this.date = date; this.times = times; } public Day() { this(null, null); } public LocalDate getDate() { return date; } public List<LocalTime> getTimes() { return times; } private final LocalDate date; private final List<LocalTime> times; } The object graph is converted to JSON using Jersey and JAXB. I have XmlAdapter s

问题 I'm carrying this on from this question, since the focus has changed. I am trying to send string data from a vapor server over a websocket. The client side is where the main question is. This code successfully receives the string, which is expected to be JSON (but not absolutely guaranteed -- out of scope). switch message { case .data(let data): print("data: \(data)") case .string(let str): // let data = str.message(using: .utf8) let jsonData = Data(str.utf8) print("string: \(jsonData)") do {

问题 I would like to be able to use computed values for sub keys when updating state in React. I understand how to use computed values in straightforward settings like this: this.setState({ [name]: value }); But I am having trouble getting key-value computation to work for a situation like this: constructor(props) { super(props); this.state = { foo: { a: 1, b: 2 } }; } const keyToChange = 'a'; const value = 3; this.setState({ foo[keyToChange]: value }); How can I make something that works like

问题 I am trying to extract the ids from each company_id from the following Json String String test = ["{\"company_id\":4100,\"data\":{\"drm_user_id\":572901936637129135,\"direct_status_id\":0,\"direct_optin_date\":0,\"direct_first_optin_date\":0,\"direct_last_optin_date\":0,\"direct_optout_date\":0,\"direct_last_form_date\":0,\"direct_last_form_id\":0,\"direct_last_promo_id\":0,\"anon_status_id\":600,\"anon_optin_date\":1446132360498,\"anon_first_optin_date\":1446132360498,\"anon_last_optin_date\

问题 I am deserialize a websocket message in real time. In the message (string of json) I receive there is a unix timestamp (long). As soon as each object is deserialized I need it to call a method ASAP so that I can capture the delay between the time the message was sent and received. With Json.NET that was simple I just added this method to my DataContract class: [OnDeserialized] private void OnDeserialized(StreamingContext context) { Timestamp = DateTimeOffset.FromUnixTimeMilliseconds

问题 I am trying to get information from the Spotify database through their Web API. However, I'm facing issues with accented vowels (ä,ö,ü etc.) Lets take Tiësto as an example. Spotify's API Browser can display the information correctly: https://developer.spotify.com/web-api/console/get-artist/?id=2o5jDhtHVPhrJdv3cEQ99Z If I make a API call with Invoke-Webrequest I get Ti??sto as name: function Get-Artist { param($ArtistID = '2o5jDhtHVPhrJdv3cEQ99Z', $AccessToken = 'MyAccessToken') $URI = "https:
