How to use posturl upload file?-CodePudding

PB in POSTURL the parameters of the function call to upload data ls_arg only one parameter, but if there are files, how to upload the file? The file to read and String format, and other parameters are combined and translated into a BLOB? Or there are other ways to solve?

Upload the binary file is a little trouble, give you a piece of code you consult

String ls_url ls_data, ls_args ls_header, ls_sql, ls_boundary
Blob lblb_args, lb_data
Long ll_cpu ll_i, ll_length
Int li_rc
Ls_url="http://localhost/PostUpdateBlob"
Ls_boundary="-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 7 db15a14291cce"//-- -- -- -- -- -- -- -- -- -- 7 db15a14291cce
"Ls_args +="-" + ls_boundary + "~ r ~ n
"Ls_args +='Content - Disposition: the form - data; Name="file"; Filename="aaa. Dat" ~ r ~ n '//name must be the file
Ls_args +='the content-type: application/octet - stream ~ r ~ n'
Ls_args +='~ r ~ n'

Lblb_args=Blob (ls_args EncodingUTF8!) + ab_data + Blob (' ~ r ~ n ~ r ~ n - '+' - ~ r ~ n + ls_boundary, EncodingUTF8!)
Ll_length=Len (lblb_args)
Ls_header="content-type: multipart/form - data; A boundary="+ ls_boundary + ~ r ~ n + & amp;
"The Content - Length:" + String (ll_length) + "~ r ~ n ~ r ~ n ~ r ~ n"
Li_rc=iinet_base. PostURL (ls_url lblb_args, ls_header, ii_httpPort, iir_msgbox)
If li_rc=1 then
Ls_data=https://bbs.csdn.net/topics/string (iir_msgbox ib_data EncodingUTF8!)
Return true
The else
Messagebox (' PostUrl error ', li_rc)
Return false
end if

Cannot upload by parameters, the previous code is used to my pb12

CodePudding user response:

Thank PB in life, you said in the # 2 "cannot upload by parameters, what meaning be? Whether does the # 1 to not do?"
I am using version 10.5, iir_msgbox object, no ib_data attribute, this property in 12 version is?

Didn't mean that, can't be directly through the parameters to upload you wrote "POSTURL function call parameters in PB, only one parameter ls_arg to upload data,", must use the method of 1 #

Answer: ib_data is an instance variable defined in iir_msgbox, to define the

Blob ib_data
