问题 I am using fetch to read data from a API: async _getDcnDetail(dcnId) { return await fetch(API_URL+'get_dcndetail', { method: "POST", headers: { 'Accept': 'application/json', 'Content-Type': 'application/json', 'Authorization':'Bearer '+ this.state.accessToken }, body: JSON.stringify({ DcnId: dcnId }) }).then(response => response.json()); } Then I call it: async componentDidMount() { let response = await this._getDcnDetail(dcn.DcnId); console.log(response); } But it "waits" eternally, it is

Rendering multiple TextInput when fetching JSON - React Native

由 独自空忆成欢 提交于 2019-12-11 13:26:16
问题 Is it possible to render multiple TextInputs from an API using React-Native? I am working on a project which fetches JSON from an API and first displays a list of Items (Only the title) using FlatList, then I click in one of them and navigates to next page which shows details of that selected item. However, there will be continuously new documents added in API which contains a different number of TextInputs, some might have 3, some 2 and so on. Document contains also a title, text, image but

Creating a form from mysql_fetch_array query

由 大憨熊 提交于 2019-12-11 13:04:25
问题 I have a field in a MySQL database called 'location' - it serves up North, South, East, West only. I have used this code to get only the 4 results that are distinct: $query_form = "SELECT DISTINCT location FROM hotel ORDER BY location ASC"; $result_form = mysqli_query($dbc, $query_form) or die('die query error'); $row_form = mysql_fetch_array($result_form, MYSQLI_NUM); I wanted to use the four results from this query to populate a table such that: <option value='1'>North</option> <option

@ManyToOne(fetch = FetchType.EAGER) fetch:加载策略 eager是马上关联加载 lazzy是只有get的时候加载 @OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL, mappedBy = "archiveTemplate", orphanRemoval = true) orphanRemoval 是从属删除 cascade:设置级联操作类型 如果是主键关联另外一个表 如果是一对多的关系（此表对应另外一个表的多张表）可以直接写 @OneToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL, mappedBy = "equipId", orphanRemoval = true) // 其中mappedBy中的值是要关联的另一张表的键 如果想用本表的非主键关联另外一张表的键可以用 @ManyToOne(fetch = FetchType.EAGER ) @JoinColumn(name="equipId", referencedColumnName="id",insertable = false,updatable = false) //其中name是本表的键，referencedColumnName是要关联表的键

问题 I am trying to connect my React app to the Jira Cloud API and can't seem to get past a 403 error. My code currently does a Auth dance using OAuth 2.0 and returns the token and cloudid.

I have ensured the user has the correct scope ([write: jira-work, read: jira

MySQL WHERE IN () + AND , PDO returns only one row

由 本秂侑毒 提交于 2019-12-11 09:33:03
问题 following query returns all wanted results if entered in phpmyadmin: SELECT postid, voting FROM postvotes WHERE userid = 1 AND postid IN (1007,1011,1012,1013,1014, 1015,1016,1017,1018,1019,1020,1021,1023,1025,1026, 1027,1028,1029,1030,1031) But PDO fails to fetchAll(). It just returns the first match like fetch(). What's wrong? PHP Code: private function userPostVotings( $postIDs ) { // $postIDs contains a string like 1,2,3,4,5,6,7... // generated through implode(',', idArray) try {

Rails.cache.fetch with expires_in only expire if new value is not nil

由 旧时模样 提交于 2019-12-11 07:48:15
问题 I want to do a simple Rails.cache.fetch and expire it after about 10 minutes. The cache gets filled with json data from an external API. However the external API is not reachable sometimes. So when the cache expires and tries to fetch new json data, the cache content gets invalid. How can I make Rails.cache.fetch ONLY EXPIRE the cache if the fetch_json returns valid data? However the cache should expire after 10 minutes if it receives new valid data. This is how I tried to do it, but it does
