React开发（119）:代码原因

  <Form.Item label="协议" name="模板文件" required>
                {getFieldDecorator(`agreementFilePath[${k}]`, {})(
                  <Upload
                    multiple={false}
                    onChange={this.handleFileChange}
                    beforeUpload={this.beforeUpload}
                    customRequest={(data) => this.onUpload(data, k)}
                  >
                    <Button>
                      <Icon type="upload" /> 上传文件
                    </Button>
                  </Upload>
                )}
              </Form.Item>

items.map不是一个function
