WSO2数据服务未绑定输入

问题描述

我正在尝试创建一个简单的数据服务，该服务将在数据库中插入具有以下定义的条目：

<data name="RESTLoggerDataService" serviceNamespace="" transports="http https">
  <config id="default">
    <property name="driverClassName">com.microsoft.sqlserver.jdbc.sqlServerDriver</property>
    <property name="url">jdbc:sqlserver://SERVER:1433;databaseName=DB</property>
    <property name="username">user</property>
    <property name="password">pass</property>
  </config> 
  <query id="CreateLog" useConfig="default">
    <sql>INSERT INTO Log (Date,Username,ServiceID) VALUES (?,?,?)</sql>
    <param name="Date" paramType="SCALAR" sqlType="STRING" type="IN" ordinal="1"/>
    <param name="Username" paramType="SCALAR" sqlType="STRING" type="IN" ordinal="2"/>
    <param name="ServiceID" paramType="SCALAR" sqlType="STRING" type="IN" ordinal="3"/>
  </query>
  <resource method="POST" path="Log">
    <call-query href="CreateLog">
      <with-param name="Date" query-param="Date"/>
      <with-param name="Username" query-param="Username"/>
      <with-param name="ServiceID" query-param="ServiceID"/>
    </call-query>
  </resource>
 </data>

这似乎不太有效，因为我通过CURL调用传递的参数都没有绑定。我尝试过：

curl -X POST -H 'Accept: application/xml'  -H 'Content-Type: application/xml' --data "@test.xml" http://localhost:90/services/RESTLoggerDataService/Log

具有以下XML：

<_postlog>
    <Date>2020-09-15 09:06:00.000</Date>
    <Username>KIRBJJ</Username>
    <ServiceID>WA233</ServiceID>
</_postlog>

但请返回以下内容：

似乎输入参数未正确绑定。有人可以看到我在做什么错吗？

解决方法

我已经使用MySQL创建了类似的数据服务，并且没有遇到任何问题。您可以尝试以下操作，看看是否进行了任何更改。通过如下添加名称空间来更改有效负载，然后尝试相同的中介。

import React from 'react';
import {RNCamera} from 'react-native-camera';
import Icon from 'react-native-vector-icons/dist/FontAwesome';
import {TouchableOpacity,Alert,StyleSheet} from 'react-native';

export default function Camera({onPicture}) {
  let camera;
  const [isTakingPicture,setTakePicture] = React.useState(false);
  
  async function takePicture() {
    if (camera && !isTakingPicture) {
      let options = {
        quality: 0.85,fixOrientation: true,forceUpOrientation: true,};

      setTakePicture(true);

      try {
        const data = await camera.takePictureAsync(options);
        // Alert.alert('Success',JSON.stringify(data));
        onPicture(data);
      } catch (err) {
        Alert.alert('Error','Failed to take picture: ' + (err.message || err));
        return;
      } finally {
        setTakePicture(false);
      }
    }
  }

  return (
    <RNCamera
      ref={(ref) => (camera = ref)}
      captureAudio={false}
      style={{flex: 1}}
      type={RNCamera.Constants.Type.back}
      androidCameraPermissionOptions={{
        title: 'Permission to use camera',message: 'We need your permission to use your camera',buttonPositive: 'Ok',buttonNegative: 'Cancel',}}>
      <TouchableOpacity
        activeOpacity={0.5}
        style={styles.btnAlignment}
        onPress={takePicture}>
        <Icon name="camera" size={50} color="#fff" />
      </TouchableOpacity>
    </RNCamera>
  );
}

const styles = StyleSheet.create({
  btnAlignment: {
    flex: 1,flexDirection: 'column',justifyContent: 'flex-end',alignItems: 'center',marginBottom: 20,},});

如果这不起作用，请启用线路日志并确认正确的有效负载已传递到数据服务。
