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 =在SAP (OAC2)中定义mime类型的文档类
• IN_CONTENT_LENGHT =导入数据类型，是文件的大小
• IT_CONTENT =导入带有文件字节的结构TBL1024表，切割成大小为1024的块
• ET_MESSAGES =只是一个检查错误的BAPIRET2表(返回表)

函数模块在Python程序中成功执行，但当我中断函数模块以检查IT_CONTENT的内容时，可以看到表中的行没有正确填写：

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']

python函数Arc.get_arc_content(filename)的提取

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中参数的结果如下：

• IN_CONTENT_LENGHT = 000000007945 (7.8kb)
• IT_CONTENT =8x1行：(4行)

使用FM ARCHIVE_OBJECT_GET检查的IT_CONTENT的预期结果应该如下所示：

所以问题是，只有第一个字节被传输，其余的都落后于零。

这与我做错了什么事有关，还是不可能正确地将二进制文件切割成1024块，并将它们转移到一个表中以实现SAP。如何在python中使用SAP的字节类型？

非常感谢你的建议/支持。

Answer 1

用pyrfc-1.9.4-py2.7-双赢amd64蛋解决了这一问题。

似乎是Windows + PyRFC 1.9.3版本的问题，1.9.4发行版工作得很好，
