要将 PDF 二进制文件上传到 SAP，我可以使用 RFC 功能模块。此 FM 需要两个特定参数：
IC_ARC_OBJECT= 在 SAP (OAC2) 中定义 mime 类型的文档类IN_CONTENT_LENGHT= IMPORTING 数据类型，是文件的大小IT_CONTENT= IMPORTING 结构TBL1024表，包含文件字节的表，切成大小为 1024 的块ET_MESSAGES= 只是一个BAPIRET2检查错误的表（RETURN 表）
函数模块在 Python 程序中成功执行，但是当我在函数模块上中断以检查内容时，IT_CONTENT我可以看到表格的行没有正确填写：
FM的python程序调用的提取：
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']
python函数的提取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 中的参数结果如下：
IN_CONTENT_LENGHT= 000000007945 (7.8 kb)IT_CONTENT= 8 x 1 行：（4 行）

IT_CONTENT使用 FM 检查的预期结果ARCHIVE_OBJECT_GET应该类似于：

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，或者是否可以将二进制文件正确切割成 1024 块并将它们传输到 SAP 的表中。如何在python中使用SAP的字节类型？
非常感谢您的建议/支持。
