B1if: How to call PUT Http in json format

[Lamine]

Hi,

I would like to perform an http call in json format to call an API that is exposed.

here is my http call method with PUT and i have an error message

com.sap.b1i.xcellerator.XcelleratorException: XCE212 Error performing the HTTP-call, HTTP-status is 404, Not Found

I use a httpCall atom :

<call xmlns="">

  <!--identifier-->

<query id="identifier" value="value"></query>

<!--optional - define your own query parameters - multiple elements allowed-->

<connect>

  <destProtocol>http</destProtocol>

  <destHost>urlmysebservice/</destHost>

  <destPort>80</destPort>

  <destPath>stocks/</destPath>

  <query>1004</query>

  <!--<proxyHost></proxyHost>

  <proxyPort></proxyPort>-->

  <method>PUT</method>

  <authentification>basic</authentification>

  <user>userws</user>

  <password>pwd</password>

<!-- <user2query> </user2query>

  <password2query> </password2query>

  <trustStoreURI>urlmysebservice</trustStoreURI>

  <keyStoreURI></keyStoreURI>-->

</connect>

<!--optional - document type definition-->

<!--<dtd>

</dtd>-->

<pltype>json</pltype>

  <!--optional - in case of POST request you specify here your request document-->

<payload>

  <xsl:value-of select="/vpf:Msg/vpf:Body/vpf:Payload[./@id=&apos;atom3&apos;]/text()"></xsl:value-of>

</payload>

<htta>

  <!--optional-->

  <!--optional - you can specify here your own http header definitions - multiple elements allowed-->

   <!-- <par id="httpheader.xml" value="text/xml"></par>

  <par id="htta.returnpltypeforce" value="text/xml"></par>

  <par id="htta.returnpltypedefault" value="text/xml"></par>-->

  <par id="httpheader.???" value="">

  <par id="httpheader.Content-Type" value="application/json"></par>

  <!--optional - you can specify here your own http header definitions - multiple elements allowed-->

  </par>

  <par id="htta.returnpltypeforce" value="json"></par>

  <par id="htta.returnpltypedefault" value="json"></par>

</htta>

</call>

Hi Lamine,

you already defined the payload type correctly:

<pltype>json</pltype>

as well as the htta segment:

<htta>
          <par id="httpheader.???" value="">
               <par id="httpheader.Content-Type" value="application/json"/>
          </par>

          <par id="htta.returnpltypeforce" value="json"/>
          <par id="htta.returnpltypedefault" value="json"/>
</htta>

please handover the <payload> as xml and not text or JSON format:

You can find the file with the required schema definition in the BizStore in following place: com.sap.b1i.system/xsd/json_pltype.xsd

You can start with an object using option 1, or with an array, using option 2.

<!--option 1 - starting in the root with an object-->
 <io xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:com.sap.b1i.bizprocessor:bizatoms" pltype="json" xsi:schemaLocation="urn:com.sap.b1i.bizprocessor:bizatoms json_pltype.xsd">
     <object>
       <!-- optional multiple of the following elements-->
       <string name="">value</string>
       <number name="">value</number>
       <object name="">...</object>
       <array>...</array>
       <bool name="">true/false</bool>
       <null name="" />
      </object>
  </io>

<!-- option 2 - starting in the root with an array-->
<io xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="urn:com.sap.b1i.bizprocessor:bizatoms" pltype="json" xsi:schemaLocation="urn:com.sap.b1i.bizprocessor:bizatoms json_pltype.xsd">
  <array>
     <!-- optional multiple of the following elements-->
     <string name="">value</string>
     <number name="">value</number>
     <object name="">...</object>
     <array>...</array>
     <bool name="">true/false</bool>
     <null name="" />
    </array>
</io>

There are also some json -> xml translators available in the internet to get the correct xml format of your json code.

Hi Bastian,

great thanks for your answer I tested and it works .

the payload format of the parameters was my mistake.

Did you know if there are  limitations on the lenght of parameters json if i want to expose a httpcall with json format as inbound ?

Thanks for help.

Regards,

Hi Bastian,

I follow this way, but have another error.
