What should I do if php calls java to pass garbled xml string?

Solution to php calling java to pass garbled xml string: first use CURL to complete the request in the command line; then change [Content-Type: application/json] when calling the interface to [application/xml] That’s it.

Solution to php calling java to pass garbled xml string:

These two jobs are needed, give one PHP colleagues provide java interface, parameter content:

<xml>
<ToUserName><![CDATA[wxcc878e3a91463bb5]]></ToUserName>
<FromUserName><![CDATA[on2BF1J3NBTUCFChovU-CNOs1MxU]]></FromUserName>
<CreateTime>1348831860</CreateTime>
<MsgType><![CDATA[text]]></MsgType>
<Content><![CDATA[this is a test]]></Content>
<MsgId>1234567890123456</MsgId>
<BrandId><![CDATA[5]]></BrandId>
<HotelId><![CDATA[5]]></HotelId>
</xml>

request header:

method:POST.

Due to objective reasons, it cannot be called directly, so postman is used when self-testing the interface, and everything is normal when calling the interface. BUT, after going online,

org.dom4j.DocumentException: Error on line 1 of document was reported during testing: No content is allowed in the preface. Nested exception: No content is allowed in the preface.

But the log output:

<xml><ToUserName><![CDATA[wxcc878e3a91463bb5]]><\/ToUserName><FromUserName><![CDATA[on2BF1J3NBTUCFChovU-CNOs1MxU]]><\/FromUserName><MsgType><![CDATA[text]]><\/MsgType><Content><![CDATA[123]]><\/Content><BrandId><![CDATA[5]]><\/BrandId><HotelId><![CDATA[5]]><\/HotelId><\/xml>

There are more escape characters \ in the tag, use regular replacement: xml.replaceAll("<\\\\ /","</");, and then the output is normal.

But the above exception message is still there. . . . . .

Almost the same solution on the Internet: use an editor to open Save As and modify the encoding format. How could the program do this! ! !

With the assistance of colleagues, use CURL to request on the command line:

curl -X POST \
  http://localhost:21010/wx_reply/reply2User \
  -H 'cache-control: no-cache' \
  -H 'content-type: application/xml' \
  -H 'postman-token: 08ae772c-7891-aaa2-01ef-30dccf5ffac0' \
  -d '<xml>
<ToUserName><![CDATA[wxcc878e3a91463bb5]]></ToUserName>
<FromUserName><![CDATA[on2BF1J3NBTUCFChovU-CNOs1MxU]]></FromUserName>
<CreateTime>1348831860</CreateTime>
<MsgType><![CDATA[text]]></MsgType>
<Content><![CDATA[this is a test]]></Content>
<MsgId>1234567890123456</MsgId>
<BrandId><![CDATA[5]]></BrandId>
<HotelId><![CDATA[5]]></HotelId>
</xml>'

Found that the parameter is actually:

%3Cxml%3E%0A%3CToUserName%3E%3C%21%5BCDATA%5Bwxcc878e3a91463bb5%5D%5D%3E%3C%2FToUserName%3E%0A%3CFromUserName%3E%3C%21%5BCDATA%5Bon2BF1J3NBTUCFChovU-CNOs1MxU%5D%5D%3E%3C%2FFromUserName%3E%0A%3CCreateTime%3E1348831860%3C%2FCreateTime%3E%0A%3CMsgType%3E%3C%21%5BCDATA%5Btext%5D%5D%3E%3C%2FMsgType%3E%0A%3CContent%3E%3C%21%5BCDATA%5Bthis+is+a+test%5D%5D%3E%3C%2FContent%3E%0A%3CMsgId%3E1234567890123456%3C%2FMsgId%3E%0A%3CBrandId%3E%3C%21%5BCDATA%5B5%5D%5D%3E%3C%2FBrandId%3E%0A%3CHotelId%3E%3C%21%5BCDATA%5B5%5D%5D%3E%3C%2FHotelId%3E%0A%3C%2Fxml%3E=

In other words:

spring The content of the body in the request is encoded. After using URLDecode.decode(xml, I got the normal content, but found that there was an extra = after the parameter (see the parameters above).

Final inspection found: It was Content-Type:application/json when my php colleagues called the interface. After changing it to application/xml, the problem was solved.
