Pyrfc：RFCTable 类型 TBL1024

Question

要将 PDF 二进制文件上传到 SAP，我可以使用 RFC 功能模块。这个FM需要两个特定的参数：

IC_ARC_OBJECT=文档class定义SAP中的mime类型 (OAC2)
IN_CONTENT_LENGHT = IMPORTING数据类型，就是文件的大小
IT_CONTENT = IMPORTING table of structure TBL1024, table with the 文件的字节，切成大小为 1024
ET_MESSAGES = 只是一个 BAPIRET2 table 来检查错误 (RETURN table)

功能模块在 Python 程序中成功执行，但是当我中断功能模块检查 IT_CONTENT 的内容时，我可以看到 table 填写不正确：

提取FM的python程序调用：

arc_object = "ZZ_PDF" 
content = Arc.get_arc_content(filename)
size = Arc.get_size(filename)
messages = []
result = connection.call("ZZ_UPLOAD_FILE", 
IC_ARC_OBJECT = arc_object,
IN_CONTENT_LENGTH = str(size),
IT_CONTENT = content,
ET_MESSAGES = messages)
messages = result['ET_MESSAGES']
for mes in messages:
     print mes['MESSAGE']

提取python函数Arc.get_arc_content(filename):

def get_arc_content(filename="file.pdf"):
    maxLineLength = 1024
    structure = []
    if filename == '':
        filename = 'file.pdf'
    with open(filename, 'rb') as file1:
        f = file1.read()
        n = 1024
        fl = [f[i:i + n] for i in range(0, len(f), n)]

    content = []
    for line in fl:
        lineapp = {
            u"LINE": line
        }
        print len(line)
        content.append(lineapp)

    return content

SAP 中的结果是以下参数：

IN_CONTENT_LENGHT = 000000007945 (7.8 kb)
IT_CONTENT = 8 x 1 行：（4 行）

IT_CONTENT 的预期结果，与 FM ARCHIVE_OBJECT_GET 核对后应该是这样的：

所以问题是只有第一个字节被传输，其余的都是尾随零。

这是否与我做错了什么有关，或者无法将二进制文件正确切割成 1024 的块并将它们传输到 table 到 SAP。 python?

如何使用SAP的字节类型

非常感谢您的 suggestions/support。

Answer 1

pyrfc-1.9.4-py2.7-win-amd64.egg 解决了这个问题。

似乎是 Windows + PyRFC 1.9.3 版本问题，1.9.4 分发完美，

非常感谢Srdjan Boskovic的支持
