我正在尝试创建一个测试示例,其中我将TextView的内容设置为存储在IPFS中的文件的内容.
我正在使用此存储库来执行我的功能:https://github.com/ipfs/java-ipfs-api
我一直在多个地方看到似乎是多索引错误despit启用multidex:
defaultConfig {
applicationId "*****"
minSdkVersion 26
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
**multiDexEnabled true**
}
dependancies{
implementation 'com.android.support:multidex:1.0.0'
}
MainActivity.java:
@Override
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
这是我得到的错误:

local error: tls: no renegotiation
我不太明白如何解释这个？我知道这不是服务器上的问题，因为当我从 python 调用相同的请求时，它返回正常。这是我的代码：
package main
import (
"fmt"
"net/http"
"net/url"
"strings"
"time"
)
func main() {
timeout := time.Duration(20 * time.Second)
client := &http.Client{
Timeout: timeout,
}
data := url.Values{
"top": {"10"},
"lDate": {"2019-01-01"},
}
req, err := http.NewRequest("POST", "https://api.*********.com/AppAvailLoads?", strings.NewReader(data.Encode()))
if err != nil {
fmt.Println("Error in construction")
}
req.Header.Add("x-cdata-authtoken", "********")
req.Header.Add("content-type", "application/x-www-form-urlencoded")
resp, err := client.Do(req)
if err != nil {
fmt.Println("Error in request")
fmt.Println(err)
} else { …我正在尝试在标准 postgres:12 docker 映像中启用流复制，这需要更改pg_hba.conf. 我已经设法强制更新postgresql.confvia 使数据库使用它（-c config_file="<>"在 docker-compose 中传递标志而不是通过 init 脚本传递标志）。
但我找不到参数或标志选项来让数据库使用我的数据库pg_hba.conf，尽管尝试在复制到的启动脚本中这样做docker-entrypoint-initdb.d。
有任何想法吗？

use tokio::sync::oneshot; // 1.0.2
fn main() {
let (sender, receiver) = oneshot::channel::<u8>();
tokio::spawn(async move {
loop {
sender.send(3).unwrap();
}
});
}
创建此错误：
error[E0382]: use of moved value: `sender`
--> src/main.rs:7:13
|
7 | sender.send(3).unwrap();
| ^^^^^^ value moved here, in previous iteration of loop
|
= note: move occurs because `sender` has type `tokio::sync::oneshot::Sender<u8>`, which does not implement the `Copy` trait
