将pdf二进制文件上传到SAP上，我可以使用RFC函数模块。此FM需要两个特定参数：
-
IC_ARC_OBJECT=文档类，以定义SAP中的MIME类型（OAC2） -
IN_CONTENT_LENGHT=导入数据类型，是文件的大小 -
IT_CONTENT=导入结构表TBL1024，带有文件的字节，切成1024尺寸的部分 -
ET_MESSAGES=只是一个BAPIRET2表，要检查错误（返回表）
该功能模块在Python程序中已成功执行，但是当我打破函数模块以检查IT_CONTENT的内容时，我可以看到表的行未正确填充：
提取FM的Python程序呼叫：
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功能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中的结果是参数的以下内容：
-
IN_CONTENT_LENGHT= 000000007945（7.8 kb） -
IT_CONTENT= 8 x 1行：（4lines）LINE1 255044462D312E3300000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 LINE2 B89B067867673EAB00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 LINE3 5BF4CB23B9A7513700000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 LINE4 61DB44B3B0AAB12500000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 ...

使用FM ARCHIVE_OBJECT_GET检查的IT_CONTENT的期望结果应该是：

所以问题是只传输了第一个字节，其余的是落后的。
这与我做错了以下事实有关，或者不可能将二进制文件正确切入1024的块并将其转移到SAP的表格中。如何在Python中使用字节类型？
非常感谢您的建议/支持。
pyrfc-1.9.4-py2.7-win-amd64.egg解决了问题。
似乎是Windows Pyrfc 1.9.3版本问题，1.9.4发行版正常，
