問題描述

wso2代理服務出錯 (Error in wso2 proxy service)

我有以下使用 google 電子表格連接器的代理服務：

<?xml version="1.0" encoding="UTF‑8"?>
<proxy name="googleTest" startOnLoad="true" trace="disable"
  transports="http https" xmlns="http://ws.apache.org/ns/synapse" statistics="disable">
  <target>
    <inSequence>
      <property name="messageType" scope="axis2" type="STRING" value="application/json"/>
      <googlespreadsheet.updateCells configKey="access">
        <key>14sCud5RqFt7O44Ol_GnTBgwFbZSnWAW‑dJ833ryfWY8</key>
        <worksheetId>1</worksheetId>
        <cellId>R2C6</cellId>
        <inputValue>Inc</inputValue>
        <row>2</row>
        <col>6</col>
        <cellVersion>1dzdhc</cellVersion>
      </googlespreadsheet.updateCells>
      <log level="full"/>
    </inSequence>
    <outSequence/>
    <faultSequence/>
  </target>
</proxy>

但是我運行此代理時出現以下錯誤：

[2015‑11‑26 19:15:04,506] ERROR ‑ RelayUtils Error while building Passthrough stream
org.apache.axiom.om.OMException: com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character '[' (code 91) in prolog; expected '<'
 at [row,col {unknown‑source}]: [1,1]

我該如何解決這個問題？請幫忙

參考解法

方法 1:

The exception you're having is the following:

Unexpected character '[' (code 91) in prolog; expected '<'

This looks like it is an issue with the contentType. Is seems like you're sending JSON data (starting with [), but the output formatter expects XML (starting with <).

Add the following property to specify that you're sending json data:

<property name="messageType" value="application/json" scope="axis2"/>
